"silencers and acoustic treatment"

Opened in 2009, Droylsden Academy in Manchester is a contemporary, open plan teaching environment. The state-of-the-art secondary school serves 1,400 pupils, however since opening it had become apparent that its design and layout had some challenges, in a large part due to the sound pollution associated with the open-plan layout. Contractors Buildmain were briefed to reconfigure a number of areas in order to minimise reverberation and improve the learning environment – and looked to CMS Danskin to identify an appropriate remedial acoustic solution.The ChallengeOne area of the school that needed particular attention was the music room, which was too large to be conducive to effective music practice. Contractors Buildmain were briefed to reconfigure the space into four separate rooms, to provide a soundproof environment for music recital and practice. The new practice rooms were to adjoin an existing classroom and the communal corridor, so controlling reverberation was an integral part of the scheme – the architects had specified the control of sound levels up to 68dB.The SolutionA complete overhaul of the existing music rooms was required – partition walls were removed and a new layout designed to incorporate the four separate practice rooms, an internal corridor and a store room. To achieve the dB rating of 68, Buildmain opted for a combination of acoustic solutions provided by CMS Danskin, including SuperPhon panels in all four rooms.In order to control reverberation in the area, Buildmain constructed the new rooms using a twin-wall method, using 15mm Soundbloc plasterboard with an acoustic matting sandwiched between the layers. The walls were then over-clad using IsoMax Acoustic Insulation Clips. A total of 20 panels were installed by direct fix to the walls of each of the four new music rooms. The 50mm thick panels were supplied in three sizes; 1200x600mm, 1000x500mm and 1000x750mm, and the colour was matched to the school’s existing interior scheme.To offer even higher levels of absorption, CMS Danskin recommended SuperPhon acoustic wall panels to reduce reverberation times and reflected sound. To assist with the correct specification, a CMS Danskin representative visited the site, at short notice, to assess the rooms and subsequently advised on the best options for the SuperPhon panels.The ResultCMS Danskin worked closely with contractors Buildmain in order to meet the very tight time frame of six weeks to install the Superphon wall panels – the project needed to be completed within the school summer holidays, so that the rooms were ready for pupils on their return to school in September 2016.Paul Bryan of Buildmain said: “We had to fit eight weeks’ work into the six-week summer holiday, and CMS Danskin impressed us with their ability to turn around the product so quickly. Not only were they able to deliver to meet our schedule, they were also able to send out an expert to advise on the best options to meet the specification, all within the timeframe.”

The congregation at Grade II Listed St Patricks Church in Bolton, can worship without interruptions from the neighbouring bus interchange, with the installation of acoustic secondary glazing. 4 large gothic arched stained glass clerestory windows were treated with internal glazed units, stopping the ingress of the sound of stationary busses which can create 70-80dB. However the tricky window was the large chancery window overlooking the altar as 4.3m (h) x 3m (w). When now inside the church, the congregation would never know there is a bus interchange just outside; the acoustic secondary glazing treatment has worked miracles.

Hush Acoustics provided an acoustic treatment for the floors within the visitor centre of the first sake brewery in the UK, Dojima Sake Brewery. The client was concerned the excessive impact noise from busy areas would transmit through the floors and affect other spaces. The solution was to develop a floating floor design involving Hush Panel 28.Hush Panel 28 was specified for use within the visitor centre to provide an acoustic overlay floor treatment for the café area, which is above the main visitor centre, to help control impact noise from the busy environment.The specification was developed in conjunction with Alinda Barua from SCABAL Architects (Studio Cullinan and Buck Architects Ltd), which represented an excellent collaboration to arrive at the required acoustic improvements.

The BROEN-LAB Polyester Based Surface Treatment is our standard coating. The treatment provides the best protection against most chemicals, UV fading and heat, we have come across. All our taps, valves and regulators are light grey, while handles can be delivered in a wide range of colours, according to the European and the U.S. standards. Do you like the look of steel? When the industrial look is preferred, we recommend our Satin Chrome surface. It gives the taps, valves and regulators an elegant metallic finish and has excellent chemical resistance properties.

The end laps and mid laps to this ageing metal roof were affected by cut edge corrosion. Liquasil's Flexlap system was specified to treat the corrosion, in all, approximately 2000 linear metres. Where sheets overlapped, the bottom sheet was masked off as this does not usually require treatment under the Liquasil system, which was designed by Chartered Building Surveyors.

This is Liquasil's BBA Approved cut edge corrosion treatment, Flexlap, being installed to a large industrial warehouse in Hemel Hempstead during September and October 2018 as part of a refurbishment project. Flexlap was specified because it is less labour intensive and requires fewer materials than other systems. The unique Liquasiul Latent Defects Guarantee was issued upon completion. This covers materials, workmanship, safe access and Professional Design allowing you to specify with 100% confidence.

The roof of this bingo hall in Hamilton, Scotland was affected by cut edge corrosion. Liquasil's Flexlap cut edge corrosion treatment was specified to solve the problem. All surfaces were first prepared using wire brushes to remove any delaminating finishes, before being prepared with the Liquasil Corrosion primer. Once the primer had cured, the Flexlap hardened silicone top coat was applied to provide a moss and lichen resistant finish, offering 10+ years protection, all backed by Liquasil’s unique, Latent Defects Insurance Warranty.

The Treatment lagoon at Market Rasen is formed by creation of an earthworks bunded area, which is then lined with JUTAMAT 5000 (GCL) as a secondary containment liner; overlain by JUNIFOL 2.00mm HDPE geomembrane as the primary containment liner. Once the lagoon is formed and lined the provision of a JUINFOL 1.00mm HDPE floating geomembrane cover to contain all odours is implemented. It is therefore possible to inflate the floating cover, providing a simple means of methane storage. Currently lagoons of this type may be constructed more for their methane generation than in the past.

Regupol studwork isolating strips helped prevent flanking sound between suites at the new Hard Days Night hotel in Liverpool.The ChallengeWhen a suitable site was finally found for Hard Days Night, the eagerly anticipated Beatles themed hotel in Liverpool, an ambitious two-year development plan was put in place to convert the historic listed building into a prestigious four star hotel.Extensive alterations to the internal area of the building created 110 guest bedrooms, which included two exclusive Lennon and McCartney suites, bars, restaurants and function rooms as well as a wedding chapel.Designed to create a unique environment with a high quality feel, it was essential that Hard Days Night lived up to the expectations of the many visitors it would welcome. Part of this meant ensuring that bedrooms were adequately soundproofed, to ensure guests were not disturbed.As with many refurbishment projects, the floor construction was timber, which left Hornport Construction, the main contractors on the project, tasked with finding a compatible acoustic treatment that would help prevent sound transfer between bedrooms.The SolutionAlthough internal wall isolation was the specified acoustic treatment, Hornport Construction was able to make the final purchasing decision as to which products would be used. After consultation with CMS Acoustic Solutions, Regupol studwork isolating strips were identified as the most cost effective solution to deliver the required acoustic performance.Manufactured from recycled polyurethane (PUR) foam, Regupol studwork isolating strips are supplied at a standard thickness of 6mm, and widths to suit specific development requirements. Sitting beneath all types of timber partitions, the studwork strips reduce structure borne noise by absorbing sound and de-coupling the connection between floor and wall constructions.Resistant to ageing and deformation, Regupol studwork isolating strips offer long-term performance and will not collapse under high point loads.Available exclusively in the UK through CMS Acoustic Solutions, Regupol studwork isolating strips are supplied with comprehensive installation guidelines, making it simple for contractors to install independently on site. Easily laid, the Regupol material is bonded straight to the subfloor, with the partition erected directly on top.The ResultAt the Hard Days Night Hotel, Regupol studwork isolating strips were used to isolate the party walls separating the corridors and bedrooms. Designed specifically for use with timber, Regupol studwork isolating strips offered the ideal solution to isolate a party wall sitting on an existing timber floor.Gerry Abraham, site manager, Hornport Construction, concludes: “The Hard Days Night is a four star hotel, so high acoustic standards were imperative. We initially looked at timber sole plates with pre-fitted isolating strips, but this was quite an expensive route. We consulted CMS Acoustics who were able to provide a cost effective and high performing alternative with the Regupol studwork isolating strip – which was just as quick and easy to use.”

The ChallengeLocated in a mixed-use development with apartments directly above the gym facilities, Bannatyne Health Club Maida Vale, was faced with a Noise Abatement Order following a series of complaints from residents occupying the dwellings above. In a bid to remediate the situation, CMS Danskin Acoustics was brought in to trouble shoot the cause of the nuisance noise.The SolutionAn initial site visit by the CMS Danskin Acoustics technical team identified the ‘free weight’ area as the source of the impact noise. Inspection of the floor treatment confirmed that a generic sports flooring tile product had been installed, yet this would not offer sufficient levels of absorption for the impact of free weights hitting the ground.Recognising that a bespoke specification would be required to achieve the necessary sound reduction, CMS Danskin Acoustics commissioned Pace Consult to conduct subjective testing on-site using a range of acoustic system build-ups.To resolve the Noise Abatement Order as swiftly as possible and to protect against any further complaints, the highest performing floor-build up was installed as follows:Regufoam 220Regufoam 190FX75 Tile10mm High Impact MatThe combination of these materials delivered a highly absorptive, durable and resilient construction which reduced the noise generated in the free weights area to a level deemed acceptable by the Council – leading the Noise Abatement Order to be withdrawn.Martin Jones, Managing Director, Pace Consult, comments: “Remediation in gym environments is more common than many realise. In the absence of any legislative standards, the specification of acoustic treatments is left very open. That’s why subjective testing is crucial in any mixed-use development, it’s the only way to be confident the products specified will deliver the exact acoustic performance required.”

Light, air, acoustics and spatial organisation are well recognised as essential elements when designers work on medical and healing facilities. This is because they have an impact on the treatment of body and mind. Now a wealth of information is available from Troldtekt, a leading developer and manufacturer of acoustic ceiling and wall solutions. This is available in an online series of articles which focuses on visions and practices opportunities and pitfalls within healing architecture. Interestingly, the internationally acknowledged MIPIM Awards have in recent years started celebrating outstanding healthcare design. The award is an acknowledgement of the role architecture plays in healing and treatment of both physical and mental illnesses. The UK’s recent Mental Health Awareness Week also reinforces the severity of the issues around mental health.Right design is especially critical for people suffering from mental illness or feeling unwell. According to Swedish architects White Arkitekter, a good example is their design for the Ostra Hospital psychiatric facility where traditional conventions have been replaced by an open and unrestricted environment characterised by tranquillity and light. The area is also not isolated from the rest of the building. Another key aspect has been specifying superior acoustics, such as in the psychiatric ward in their design for the Södra Älvsborg Hospital in Borås. Recently shortlisted for the European Healthcare Design 2021 Awards in the Mental Health Design category, their starting point was that the architecture must cater for people’s need to feel safe and to improve their well-being. In designing the interior, the emphasis has always been on soft, round shapes (no sharp edges), while the colours strike a balance between providing stimulating sensory impressions and instilling a sense of calm. They say that the choice of materials, such as wood, also plays a key role because it adds warmth and naturalness. “Sound is an environmental factor that we’re very careful to incorporate correctly in psychiatric buildings,” explains White architect Peter Johnstone. “Creating subdued and comfortable acoustics helps to counteract stress and anxiety that can otherwise be triggered by a noisy environment. Apart from Sweden, international research shows that the therapeutic environment can be crucial to the treatment of mental disorders. In fact, research from Chalmers University of Technology proves that the right interior design, including perfect acoustics, can reduce both the use of physical restraint on psychiatric wards as well as the number of sick days among employees.Founded on the Cradle-to-Cradle design concept, Troldtekt’s natural and inherently sustainable panels are available in a variety of different surfaces and colours and contribute positively to a building’s BREEAM, DGNB and LEED ratings. In addition to their high sound absorption and tactile surface, they offer high durability and low cost lifecycle performance. Available in various sizes and in four grades from extreme fine to coarse, the panels can be left untreated or painted in virtually any RAL colour. Samples, case studies and technical guidance are available from tel 01978 664255 or Troldtekt.co.uk while the theme can be found at https://www.troldtekt.com/news/themes/healing-architecture

In this project, Hush Acoustics were tasked with a project in Douglas, the capital of the Isle of Man, to provide a solution for a beautiful mid terraced property recently converted into 4x spacious apartments over four floors.With the apartments located very close to a road, the issues became apparent after spending some time inside, with road traffic noise as well as public background noise clearly heard.Key to resolving the issues was to ensure appropriate acoustic measures were carried out when converting this existing property into apartments, and that the party walls and/or ceilings met the required standards for conversion under the Building Regulations, Approved Document E.Working with Andrew Bentley, the architect and Kevin Cretney of Kinrade Construction, a solution incorporating the following was provided:HD1044 ACOUSTIC BASEMENT SYSTEMThis system has been created with residential properties in mind and is made up of a combination of materials that offer excellent sound reduction within the specified area.The basement system is made up of Hush Slab 100 which is tightly packed within the joists, Hush Deep Resilient Bars, which are fixed horizontally to the underneath of the joists and Hush Multi Panel which is fixed to the underside of the bars. 15mm of Fireline Plasterboard is then used to over board the Multi Panel.HD1041 ACOUSTIC WALL LINING SYSTEMThis system has been thoroughly tested to exceed Building Regulations and our competitor’s wall lining products. It is made up of Hush Multi Panel, the 15mm Fireline which is then installed over, ensuring joints are staggered. The perimeters are sealed using Hush Isolation Tape, as well as our Acoustic Sealant. These boards are then fixed to the Deep Resilient Bars and Hush Slab 25 is fitted in between. The Bars are then fixed horizontally to the wall.The benefits of this system are its high standards of airborne sound reduction, can reduce both flanking and direct sound transmission and creates a minimum loss of space.HD1038 HUSH ACOUSTIC FLOOR SYSTEM MF28This floor system is a highly rated performer and has again been thoroughly tested within areas that require exceptional acoustic control. Made up of Hush Panel 28 which is laid over the chipboard deck and sealed using Hush Seal 20. The Hush MF Ceiling System is then installed to the underside of the joists, to the back of the plasterboard lining. Hush Slab 100 is then installed tightly within the ceiling void. Two layers of plasterboard is then installed to the underside of the MF system and all perimeters sealed with the Hush Acoustic Sealant.Outstanding resultsTests carried out on completion of the acoustic treatment showed immediate results, which completely exceeded the acoustic requirements for conversion within the Building Regulations and also surpassed New Build standards.Chartered Architect, Andrew Bentley, said, "Thank you for all your help and support. I will be happy to use your products again in future."

Providing a hermetically sealed entrance to the National Treatment Centre in Inverness, Scotland

Identified as one of 13 national Infrastructure sectors by the UK Government, the water industry has invested heavily in recent years upgrading perimeter security systems with the aid of LPCB (Loss Prevention Certification Board) and LPS1175 rated security fencing. The installation of 450 metres of fencing and various gates, including specially fabricated panels and bespoke fabrication work, was completed at an undisclosed water treatment works in the north of England as part of these upgrades. The project involved LPS1175 Issue 8: B3 (SR2) Combi™ SL2 Palisade security fencing, chosen by the Main contractors NMCN for its ease of installation, requiring no specialist tooling and the fact the system was designed to rake easily, solving issues raised with other security fencing solutions previously used.

BackgroundPure Gym has recently opened a brand-new facility in Canterbury. The gym hosts over 220 pieces of state-of-the-art equipment, including cardio apparatus, treadmills, rowers and spin bikes. Customers also get to benefit from a free weights zone and a fixed weights area, as well as access to a multitude of fitness classes.The ChallengeSituated on the first floor of a mixed-use development, a jack-up floor was specified to prevent vibrations from transferring into the building structure. However, to ensure the development was fit for purpose, Pure Gym believed additional treatment was needed to further enhance the performance of the floor and reduce unwanted noise.As such, Pure Gym commissioned an acoustic consultant to produce a report outlining the exact performance criteria that would need to be met across different areas of the gym. The report recommended individual performance standards for the free weights zone and the rest of the studio. One of the main challenges was to find a solution that would meet the specification but also be delivered for installation within a strict two-week period.In addition to the prompt supply time, the solution also needed to match the Pure Gym aesthetic guidelines and corporate colours. Pure Gym approached CMS Danskin Acoustics detailing the project specification, seeking advice on what solutions were available to meet the criteria.The SolutionCMS Danskin Acoustics used the consultant’s report to identify system build ups that would best achieve the specified performance detail. Two separate build-ups proposed by CMS Danskin Acoustics were subsequently approved for use. For the free weights area, a build-up of two layers of Regufoam® in grades 220 and 270, plus a 43mm everroll® Weightlayer (everroll multitile 43mm) was supplied. For the remainder of the studio, two layers of 15mm Regupol® Vibration 480 was supplied, complimented by a final floor finish of 10mm everroll®.The specified finish of black and grey EPDM was also matched by CMS Danskin Acoustics and all materials were produced for installation within the strict two-week time frame.The ResultCMS Danskin Acoustics was able to quickly identify solutions with the required technical capabilities from across the breadth of its product portfolio. The volume of material needed was in stock, allowing a quick turnaround for Pure Gym to meet the specified project completion date.Pure Gym opened to the public on the proposed launch date and is now fully operational. The treatments provided by CMS Danskin Acoustics are providing a robust solution to reducing unwanted noise, protecting the structure of the gym floor and preventing vibrations travelling into the structure of the building.CMS Danskin Acoustics is now one of Pure Gym’s preferred suppliers and has since worked on projects such as the new build of a two-storey facility in Croydon, and the refurbishment of the Winwick Quay site in Warrington.“The service CMS Danskin Acoustics provides is of an extremely high standard. Their expert advice, quality of the product and efficiency in getting the materials to site, were instrumental in allowing us to complete the project on time. The superb service has instilled a confidence in us to develop our relationship with CMS Danskin Acoustics as a trusted supplier,” commented John Graham, Pure Gym Property Development Director.

Millets Farm is a family run farm centre including farm shop, garden centre, leisure attractions and activity areas.  This award winning location has now turned to Marsh Industries twice in 5 years for expert advice on how to best support the expanding facilities onsite.In the first instance, a sewage treatment plant was required for its Children’s Activity Centre in 2017.  A Marsh Ultra:Polylok 125PE was selected for this popular destination.In 2021 this thriving regional attraction identified that the existing sewage treatment arrangements for the main Farm Shop, Restaurant and Function rooms needed to be upgraded.  Millets Farm again turned to Marsh Industries.  This time a Marsh Ultra:Polylok 250PE was required to cover the variety of facilities and their associated footfall alongside the increased staff numbers. With installation successfully completed in the Autumn between school holidays.

Silverstone Universal Technical College is one of the first UTCs to open in the UK.Silverstone College and other UTC’s are part of a government-funded programme to give those aged 14 – 19 unparalleled pathways into University Entrance and rewarding industry careers.We supplied and installed the Class ‘A’ Sound Absorption Acoustic Treatments throughout the new build college. Collaborating with the project team, Architect and the appointed Acoustician an effective and aesthetically pleasing sound absorption solution was developed which meets the Building Regulation requirements of BB93.A variety of Acoustic Absorption products were used in this project including, Absor-R Acoustic Baffles, Absorb-R Acoustic Rafts, Absorb-R Acoustic Fabric Wall Panels and Acoustic flooring.

NORclad have been supplying the timber cladding on this project over the past couple of years, a mixture of Tongue and Groove boards, feature fins, and open rainscreen profile.Areas for accommodation and high footfall required to also receive EuroClass B fire treatment.A HomeGrown Larch was selected for this project, having a fair spread of knots and character to be in keeping with its surrounding, a great example of selecting a suitable timber species that fits. Potentially if a timber with a lower knot content, or less defined grain would not have worked as well as this, in these natural surroundings.With English Grown Larch only being classified as slightly/ moderately durable by TRADA, the decision was made to use a high pressure treatment on all of the timber supplied for this project. NORclad Lite preservative treatment was selected, which allows the timber to naturally weather down to the silver grey as you’d expect from timber after being exposed to UV light, the treatment also offers a 30 year warranty against rot & insect attack.

Client: NHS HighlandLocation: Inverness, Scotland, UKYear: 2023Project size: 400 m²Vebro systems: vebrobound StoneAn attractive, slip-resistant alternative to tarmac was required for the outdoor areas surrounding an elective care centre in the heart of Inverness Campus.NHS Highland, one of the fourteen regions of NHS Scotland, provides physical and mental health services across the Highland and Argyll and Bute Council areas, covering an area of 32,500 km² and serving a population of 320,000 people.NHS Highland has opened a new elective care facility at Inverness Campus, a hub for world-class research and development in the life-sciences sector.The National Treatment Centre, based at the Inverness Campus, comprises an ophthalmology outpatient department, ophthalmology and orthopaedic theatres, inpatient wards, an imaging and diagnostics suite, as well as collaborative spaces, educational facilities, and office spaces.Not only does the centre cater to local needs, but it also goes beyond by fostering innovation and research, enhancing the scope and impact of clinical services provided.Vebro Polymers has supplied vebrobound Stone, a fully permeable, SUDs compliant resin-bound aggregate system that is ideally suited for use in public-facing external applications like hospitals and healthcare facilities. The permeable, seamless polyurethane resin bound aggregate system is designed for installation directly onto tarmac or concrete on terraces and external areas of commercial and institutional venues and delivers a stylish and low maintenance alternative to loose gravel, block paving or concrete.Available in a range of attractive aggregate blends, vebrobound Stone can complement existing structures to deliver a stunning welcome to institutional facilities such as this.Hendersons, established over 40 years ago and based in Moray in Scotland, provide first class resin flooring installation throughout Scotland.The company, who also offer a range of other services including painting, decorating and industrial cleaning, deployed their dedicated resin flooring team to transform Glenturret Distillery. Hendersons prides itself on the continual training of existing staff and development of trainees across its business, ensuring it continues to offer an unsurpassable service.

Oscar Elite exceptionally smooth acoustic plaster used on Grand Design Series 7. Oscar Acoustics' experienced in-house operatives installed Oscar Elite acoustic plaster directly onto the original concrete soffit at a depth of only 25mm and up the vertical faces into the feature light lantern. The end result was a flat white acoustic plaster finish, smoother than most conventional plastered and painted finishes, which made this potential sonic battle ground a relaxing and comfortable place in which to spend time.

One of the UK’s largest utility companies required adequate security protection to their portable water sites. Water is treated from the local river supply at the site, which then supplies the local area. Therefore, it is important to ensure that the site is protected from any trespassers or any other miscreants who may be up to no good. Sites of this nature must be kept safe and secure to ensure that the water supplies to the public are kept as clean and safe as possible. The site is operated 24/7 and required additional security support to ensure the large site is kept safe and secure.Project Brief for Water Treatment Works SecurityThe site is required to be protected in line with the company Risk-Based Approach (RBA) and security requirements from DEFRA with recommended security upgrades to the physical perimeter security fencing, video surveillance systems (VSS), access control and intruder detection systems.Perimeter security fencing was required to be upgraded to at least LPS 1175 SR2 (B3) level with detection and access control and careful consideration to the surrounding forest, home to several animals, including Wild Boar. This causes several problems for the site, including damage to the existing fence and potential water quality issues. In addition, the Drinking Water Inspectorate (DWI) are particularly interested in the vermin and pest control for the site, so designing the security solution had to consider this.The SolutionBinns Security was appointed as principal contractor for CDM and project managed the whole project from start to finish, including coordinating works. Based on the site's requirements, Zaun’s HiSec Super SR2 fencing was selected to upgrade the existing non-rated perimeter fencing and gates to LPS1175 SR2 standards, providing the client with perimeter fencing system with a guaranteed delay of at least 3 minutes.Designed with a height of 2.4m as a minimum with a 358 anti-climb mesh configuration makes it very difficult to scale and prevents climbing aids. To combat vermin and pest control, the perimeterfencing is also required to be buried at 300mm, which stops the vermin and also prevents burrowing from any potential intruders.Both pedestrian and vehicular gates were also upgraded to LPS1175 SR2 to match the fence line and provide operational access without compromising the site's security. This single layered LPS1175 SR2 rated fencing system was accompanied by Harper Chalice’s perimeter intrusion detection system (PIDS) FenceSecure, which provides an early warning for any unauthorised access. Additionally, this system provided a full perimeter PID system covering fencing, gates and pedestrian access points.more...

We were asked to provide teams at Scottish Water’s Treatment Works in Whitehillocks, Glenesk with safe access to a large chemical bund for operational and maintenance activities.A new installation, our client chose a GRP solution for its non-corrosive, low maintenance properties. We were tasked with designing, fabricating and installing the new platforms, the last phase taking just four days.As always, the project began with a detailed survey after which the CAD engineers created drawings to enable costings. The platform was initially constructed on our site at Brantham to ensure every component was accounted for and that the completed structure would meet all the requirements of our client.

The developer of an apartment conversion scheme in the Pennine hills village of Diggle near Oldham wanted to achieve superior sound reduction standards in the walls and floors and go beyond the minimum requirements set out by the Building Regulations.The Old Mill House project involved transforming a Victorian industrial building into several residential dwellings. The project’s design needed to comply with the requirements of Approved Document E, which sets out minimum standards in England and Wales for airborne and impact sound transmission between dwellings where there is a Material Change of Use.However, to deliver the highest quality living accommodation to potential buyers, the developer insisted that the acoustic specification not only met the minimum standards but went beyond them.To achieve their goals for the floors and walls, they approached Hush Acoustics for assistance in developing the specifications and providing the required products.Given the unique nature of the properties being created, the acoustic design for the flooring had to be compatible with underfloor heating and more unusual floor finishes such as stone tiling.The specification developed by Hush Acoustics for the separating floors beneath the floorcoverings featured a plywood timber deck, below which was the underfloor heating system and 8mm Hush FFR resilient underlay.For the ceiling side, Hush recommended standard acoustic insulation for use within the timber joists, two layers of 15mm Fireline plasterboard attached to the underside of the joists, the Hush MF Ceiling System to allow Hush Slab 100 to be fitted in the void created, finished with a layer of 15mm Soundbloc plasterboard.For the separating walls, two specifications were developed according to the types of walls. In areas where there was an existing masonry wall, a wall lining consisting of independent stud work, Hush Slab insulation and Soundbloc plasterboard was developed. In other areas of the scheme, a twin timber stud wall is recommended, again featuring Hush Slab insulation and Soundbloc plasterboard.As part of the process, the Hush Acoustics team undertook many site visits and guided the design and build process to ensure the correct installation was followed, and pre-completion testing was also arranged.The solutions developed and provided by Hush Acoustics fully met the developer’s goals to go beyond Approved Document E’s compliance standards according to the pre-completion tests.

ACOUSTIC insulation experts CMS Danskin Acoustics has worked with historic Standon Hall to specify and supply a range of acoustic products to reduce the impact of airborne and impact sound transmission in the Grade II listed Staffordshire venue.During the course of redeveloping the early 20th century country house into a high-quality wedding and business venue, Standon Hall made acoustics a key element for investment. CMS Danskin Acoustic’s in-house technical team conducted a site assessment in order to specify an insulation strategy to address structure borne noise and absorb sound.The objective was to prevent noise transfer between ground floor functions rooms and nine bedrooms and suites above. Andrey Magiy, Standon Hall’s MD, said, ‘During this two-year project to transform the hall into an outstanding venue we had an opportunity to address acoustics as floors were lifted to install new services. It was as important to prevent sounds from above being heard in meetings and conferences below, as it was to prevent noise from ground floor functions filtering up into the bedrooms.’The resulting acoustics strategy from CMS Danskin Acoustics involved the installation of 600sq m of Smartspan floor panels, Karma TNF70 high density stone-fibre batt and REGUPOL acoustic isolation strip. Challenges included the need to work from above to avoid disturbing fine, moulded lath and plaster ceilings below and the necessity to specify high performance acoustic materials of a thickness that wouldn’t increase bedroom and bathroom floor levels.Andy Hayes, CMS Danskin specification manager and IAO Affiliate, said, ‘Smartspan panels span across bearing structures such as, in this case, joists. They provide high acoustic performance, are easy to install, come in different thicknesses, such as the 32mm and 18mm used at Standon Hall, and have a reaction to fire classification (EN 13501-1) A1.‘Smartspan was also valuable for use in bathroom floors as it has excellent thermal conductivity making it ideal over UFH systems, has surface water absorption of only (EN20535) <300g/sq m is suitable for stone and ceramic finishes and, with a tongue-and-groove profile, it’s straightforward to install.’REGUPOL Acoustic Isolation Strip was also incorporated to reduce impact noise from first floor footfall. The strips are designed to sit beneath all types of partition walls and are described by the company as a simple and effective way to reduce structure borne noise. ‘Quick and easy to install, they provide long term performance without collapse or ‘bottoming’ out under high point loads, are resistant to ageing and deformation, are manufactured using recycled materials and are 100% recyclable.’~Karma TNF70 was also specified in places. Says the company: ‘It’s typically used in refurbishment projects for improving existing structures where access is only available from above and where additional acoustic and fire performance is required, such as in flats, offices, shops, and hotels. It’s lightweight, quick to install and is a dry system that won’t damage sensitive lath and plaster ceilings or fine plaster mouldings.’‘The products have been absolutely brilliant and we have great acoustics results for the primary rooms,’ said Standon Hall’s Andrey Magiy. Standon Hall opened for private hire for weddings and corporate events during 2021 and the bedrooms and suites were completed and launched in spring 2022.

Col.legi Montserrat in Barcelona is one of the most innovative schools in Spain. The school has departed from the traditional system of silence and listening to explanations and encouraging discussions. The means? Acoustic quality and low frequency absorption.

Hush Acoustics has successfully addressed a party wall noise problem for a homeowner in north London through the installation of its slimline HD1041 acoustic wall system, improving sound insulation without significantly compromising the room size.The owner of the semi-detached house in Hackney, contacted Hush to find a solution that would enhance the acoustic performance of a separating wall, ultimately improving the quality of life for their neighbours.The properties suffered from inadequate acoustic control within their original construction, allowing everyday sounds to pass through the party wall and become clearly audible next door.The brick wall in this particular case lacked the necessary mass and density to block sound waves generated by speech and activities like children playing. As a result, the noise disturbance caused stress and anxiety for the neighbours.Key to homeowner’s wishes was a solution that would not significantly reduce the size of the room. While retrofitting the wall with acoustic treatment would naturally increase its depth, the client understood the trade-off between volume reduction and improved soundproofing.Hush proposed three fully tested acoustic wall systems, each offering varying build-up thicknesses and sound reduction levels ranging from good to better and best. After thorough discussions between the Hush team and the homeowner, it was agreed that the Hush HD1041 Acoustic Wall Lining System would deliver the optimal solution. This system utilises a combination of high-performing acoustic materials, resulting in a wall lining that is only 55mm deep.A local contractor completed the installation of the acoustic wall system, with Hush providing full technical support and supervision throughout the process.Expressing their satisfaction with the improvements delivered by the system’s installation, the client said:“We have completed the work on the wall, and the results are excellent. The neighbours can barely hear anything now, and they no longer get disturbed when my son is up in the middle of the night. A heartfelt thank you to you and the team.”

A stunning design by architects Townscape, Peter O’Sullevan House is located at the front entrance of the British Racing School in Newmarket. It provides the horse racing community in East Anglia with a local specialist facility for treatment and training. The facility incorporates a hydrotherapy pool, gymnasium, treatment rooms, changing rooms, conference room, offices and meeting rooms. Forza Doors supplied high dB acoustic American White Oak veneer fire doors and solid American White Oak frames as well as Class 0 spread of flame fire-rated wall cladding panels. All the veneers were laid horizontally to match perfectly down the length of the corridors and open spaces. The feature grooves embedded into the doors provide a smart contemporary look and align with the adjacent panels.  As this innovative building needed a high level of internal finishes and fittings throughout, the contractor RG Carter chose Forza Doors. Just one of several jockey rehab centres we have had the privilege to supply in recent times. Consisting of open plan areas, treatment rooms and hydrotherapy zones, the finished project looks stunning.  

CMS DANSKIN ACOUSTICS recommended a bespoke combination of industrial acoustic materials to ensure noise at work compliance at ExxonMobil Oil Refinery. The ChallengeFawley Oil Refinery is the largest oil refinery in the UK. When ExxonMobil found that the noise output from two industrial fans at the refinery exceeded the levels specified by The Control of Noise at Work Regulations, it consulted CMS Danskin Acoustics for advice. To ensure the most cost effective and high performing materials were specified, CMS Danskin Acoustics evaluated the noise reduction required on-site. Evaluation of the acoustic data revealed that noise levels in excess of 118dB at 125Hz were being emitted by the fans. Based on these criteria, the technical team at CMS Danskin Acoustics recommended the use of a combination of specialist materials from its industrial acoustic range. The SolutionTo control the low frequency-biased sound, CMS Danskin Acoustics recommended and supplied the SuperLag Quietslab Laminate with Acoustic Barrier Type WB10 combination for the fan casings and associated ductwork. Creating a multi-layered, high performance system, two layers of SuperLag Quietslab Laminate, totalling 250mm thickness, with a core of 5mm Acoustic Barrier Type WB10, were bonded onto the fan casings and ductwork. A direct coupled lagging system, SuperLag Quietslab Laminate comprises long-stranded mineral fibres thermo-set with resins for the absorption of sound at the surface, as well as a high mass inner acoustic barrier core to reduce the transmission of sound through the material. Manufactured from a weight-enhanced, high-density material, Acoustic Barrier Type WB10 provides a flexible and cost effective treatment for chemical and refinery applications. In total, 1,000m2 of the SuperLag Quietslab Laminate/Acoustic Barrier Type WB10 materials were installed around the fans and ductwork to achieve the high levels of sound reduction required.ResultsThe high performance bespoke system specified by CMS Danskin Acoustics, significantly reduced the noise generated by the fans. This enabled ExxonMobil to comply with The Control of Noise at Work Regulations by bringing noise levels under the 85dB compliance level.

When Galaxy Insulation – Hush Acoustics’ parent company – moved into its new regional offices near Glasgow, the team wanted to ensure the spaces were pleasant to work in and acoustically comfortable.The offices at Blantyre to the south of the city are contained within a modern building in a business park. This is typically designed and optimised for versatility, energy efficiency and low maintenance with large windows to allow for plenty of natural light transmission.As is common with office buildings of this type, given the relatively low levels of soft materials and furnishings used in the fit-out and décor, once the team moved into their offices it quickly became apparent that the environment was echoey and acoustically uncomfortable as a result of reverberation.RESOLVING ACOUSTIC ISSUESBeing familiar with this issue, the team at Galaxy Insulation were keen to ensure that everyone in the new office could work without being disrupted by excessive background noise, which is often caused by soundwaves reflecting off hard surfaces like glass and wood.Galaxy Insulation turned to the team at Hush Acoustics for assistance with this issue, having seen how it had worked with clients across the UK to address similar reverberation problems. Hush started the process by conducting an acoustic survey to determine the extent of the problem and identify where sound absorber panels could be fitted to resolve the issue.Hush proposed fitting six Hush Absorber 50 panels in varying sizes, including 1800x1200mm, 1200×1200 and 1000x1000mm, which would be strategically mounted on the walls of the offices.This is a Class A absorber that comprises a specially formulated 50mm thick acoustic foam, hand-finished with an interior fabric, which is applied to the face, edges and back return.ADDING A CREATIVE DIMENSIONAs Hush Absorber panels are always manufactured to order in a fabric cover coloured to the requirements of the client, this presented an opportunity for Galaxy to use the new panels for decorative purposes too.Rather than apply a single colour or generic pattern, the local team leading the project wanted to celebrate their great city by printing large photographs of famous Glasgow landmarks onto the panels. A number of high-resolution photographs were sourced and supplied to Hush to arrange the fabric printing as part of the manufacturing process.Hush manufactured and supplied the absorber panels within three weeks from the date of order, and installed them all in a matter of hours to minimise disruption at the Galaxy Insulation offices. Feedback from the team gave the panels an immediate thumbs up, with the difference in acoustic comfort noticed instantly and the images giving the office a distinctive new look.CLIENT FEEDBACKJim Downie, Scotland’s Managing Director of Galaxy Insulation said: “What a transformation the absorber panels have made! Firstly, they look amazing with the vibrant colours of the photographs reproducing extremely well, reflecting our intention to celebrate Glasgow’s iconic buildings and skyline.“Acoustically, the offices are far more comfortable for everyone. We’re an extremely busy office here as we work with customers across Scotland, so we’re always speaking on the phone or talking to each other to deliver for clients. We wanted to ensure high levels of background noise did not result in reverberation and make the working environment potentially unbearable.“The team at Hush Acoustics were quick to understand our requirements which gave us complete confidence that their proposed solution would meet our needs. Now the panels are installed, it is clear that the Hush Absorber 50 panels have worked exactly as planned, working in the background to minimise the risk of nuisance reverberation.”

BackgroundThe Injured Jockey Fund (IJF) Oaksey House rehabilitation centre in Lambourn, Berkshire, was opened in 2009 by the IJF Patron, HRH The Princess Royal. Oaksey House provides specialist rehabilitation treatment for physical and neurological injuries, it has a fully equipped gym which includes a state-of-the-art anti-gravity treadmill. The centre has respite accommodation available for those receiving extended treatment and their carers. Educational courses on fitness and nutrition for the general well-being of young and aspiring jockeys are also on offer.Oaksey House is not only a rehabilitation centre for jockeys, but anyone with physical or neurological injuries. Although the centre was only opened in 2009, it was decided that a refit was required to make improvements to further support the people that pass through its doors. The refit included moving the gym to the first floor and building a hydro pool on the ground floor.The ChallengeRelocating the gym to the first floor was no easy task, primarily because the building structure was composed of a steel tray and concrete base. To accommodate gym activity, the floor build-up would need to be enhanced to prevent noise and vibrations travelling through the building.As a charity, the IJF had limited funds to work with, so flooring specialists, Sport & Fitness Flooring, worked with the architect and an independent consultancy to identify an effective solution within the specified budget. Moreover, the floor had to be designed to meet the needs of four distinct areas: a cardiovascular zone, a running track, main gym area and an entrance lobby.The project was unique because various performance requirements had to be met across the four areas but the floor level needed to be consistent throughout to make it accessible for wheelchair users. Sport & Fitness Flooring consulted CMS Danskin Acoustics – Gym Flooring Division to advise on potential solutions to address this challenge while remaining cost effective.The SolutionCMS Danskin Acoustics worked with Sport & Fitness Flooring to undertake on-site subjective testing to determine the level of sound reduction and vibration control that would be required. The primary objectives were to prevent vibration travelling into the structure of the building thus resulting in potential structural damage or unwanted noise levels on the ground floor below. Samples of different build ups were provided by CMS Danskin Acoustics on site for testing within a day of the initial request.“Throughout the planning stages CMS Danskin Acoustics acted as a ‘springboard’ for our ideas. They were extremely helpful in offering their expertise to find solutions to meeting the performance requirements of the floor,” said Darren Wood, Director of Sport & Fitness Flooring.Sport & Fitness Flooring worked with CMS Danskin Acoustics to identify a way of raising the floor in different areas to meet a consistent 84mm thickness throughout, without having an adverse effect on the acoustic performance of the flooring. CMS Danskin Acoustics developed a bespoke specification for the four key areas, with solutions subsequently presented to the architect and approved for use on the project.The ResultCMS Danskin Acoustics was able to meet the performance, volume, and diversity of product needed to effectively treat the floor at a competitive price and on budget.In the main gym area, a high-performance combination of everroll® Multitile (everroll Multitile 27mm) was bonded to Regupol® 40/80 Acoustic Foam and fitted to Regupol® Vibration 300. In the cardiovascular zone, Multitile (everoll Multitile 27mm) was bonded to Regufoam® 270 acoustic PU foam and fitted to ply which was adhered to Regupol® Vibration 300. The track was treated with BOK Sprint track bonded to a everroll® Impact Pad elastic layer, ply build up and Regupol® Vibration 300. Finally, concrete effect Luxury Vinyl Tiles (LVT) were used to create a purpose-built ramp up to the 84mm floor level from the entrance lobby.On day one of the build schedule, there was a timed delivery of the material. The bespoke order was exactly as specified and allowed installation to begin immediately with no delays. CMS Danskin Acoustics attended Oaksey House to provide expert on-site support and technical guidance on the installation. The project finished a week ahead of schedule, on budget and the flooring met all the performance requirements that were specified. Crucially, a consistent floor level was successfully achieved throughout the gym.“It’s quite common for suppliers to just sell a material and move on, but CMS Danskin Acoustics deliver a first-class expert and professional service from initial technical involvement, to tracking, delivery, installation and sign off. We regularly work with CMS Danskin Acoustics on various bespoke projects and are always confident in the solutions and expertise provided,” concluded Darren.

Achieving a Building Regulations compliant level of soundproofing in residential conversion projects demands the use of superior quality soundproofing materials and systems, which are deployed in the right way. It is an approach that a recent development in the south Manchester suburb of Levenshulme perfectly encapsulates, with outstanding results for the developer and future residents.Hush Acoustics was tasked to provide a solution for a conversion project at 31 Albert Road, Levenshulme by Meridian Construction & Refurbishments. It was converting the five-bedroom Victorian dwelling into two residential flats, which meant the separating floors had to be constructed in a way that would meet the acoustic standards set out in Approved Document E of the Building Regulations for England and Wales.Under Approved Document E, ‘material change of use’ projects like this must incorporate soundproofing in the floors between individual dwellings to reduce the risk of nuisance sound transmission. Evidence that the floor construction complies with the standards is normally provided to building control through post-installation acoustic testing, which on this project was undertaken by C80 Solutions.Hush Acoustics was invited to attend the site by Meridian when the building was at its early rip out stage. This provided an opportunity to get a clear understanding of the situation and discuss the options for the separating floors to ensure they would meet the requirements of Approved Document E.The floor structure was a traditional timber floor with floorboards. There was only a very limited specification in the design, so Hush was able to help by providing specialist technical consultation to develop the most cost effective and easy to install solution for the Meridian site team.Following the site visit and inspection of the building, Hush Acoustics’ soundproofing specialists developed an acoustic product specification for the separating floors that would not only meet the minimum standards of the Building Regulations, but exceed them with ease.Hush-Panel 17, a thin MDF overlay board which incorporates a 10mm Hush-Felt resilient layer, was installed over the structural deck. This was glued using Hush-Bond Panel Adhesive and isolated at the perimeters using Hush-Seal 20.The structural deck consisted of the original floorboards that had been overboarded with a thin plywood. This provided a solid flat surface to install the acoustic flooring. The existing ceiling was left in place where possible to avoid the need for ripping out where it was not required, which allowed for a new acoustic ceiling to be installed. This consisted of two layers of 15mm Fireline plasterboard on a suspended frame with Hush-Slab 100 sound absorber slabs placed within the ceiling void.As part of the service, Hush Acoustics arranged for the acoustic testing to be carried out by testing partner C80 Solutions. They recorded the following results:Airborne – 53 dB DnTw+Ctr and 52 dB DnTw+Ctr (the higher, the better)Impact – 48 dB LnTw and 43 dB LnTw (the lower, the better)These are very good acoustic figures for a separating floor in a residential conversion project of this kind, demonstrating what can be achieved with a combination of high quality soundproofing materials are combined and installation correctly.Ultimately, this outstanding acoustic performance for the separating floors will help to ensure a high level of satisfaction for the future residents of these modern apartments.

Liquasil's BBA Approved cut edge corrosion treatment was specified for use on this metal roof on an industrial unit in central Birmingham. Liquasil SWT Primer was first applied to all rusted areas. SWT stands for "Surface and Wet Tolerant" meaning that it can be applied to wet and rusted surfaces. The primed areas were then coated with Liquasil's Flexlap - a purpose made silicone polymer coating to provide total protection from further lap corrosion.

JCW Acoustic Supplies supplied & installed an acoustic enclosure to counteract the increase noise generated by the installation of a new more powerful generator required due to expansion.

Hush Acoustics provided a range of acoustic products for the construction of Warren Court, a new development of 9x luxury two bedroom apartments. Working with Marlowe Building Contractors, we provided advice and materials for the apartments’ soundproofing to give acoustic performance better than New Build standard.The Standard Assessment Procedure (SAP) energy ratings had already been calculated and passed before Hush were involved with the acoustic design. The building’s structure consisted of lightweight masonry walls and a timber joist floor structure, which could not be changed due to SAP compliance. As a result, Hush was tasked with developing a comprehensive design to ensure compliance to Approved Document E of the Building Regulations with this form of construction detail. The biggest issue was the continuous lightweight block walls that may be thermally very efficient, but present major difficulties acoustically. To go over and above the new build standard, it was necessary for all blockwork and timber floor joists to be isolated on Hush Resilient Seating. Ceilings were also isolated by using Hush Suspended Ceilings in the main and an Enhanced Clip and Channel System was used where the floor/ceiling heights were at a premium. Hush Panel 28 was provided throughout as the floating acoustic flooring system.We carried out pre-completion sound tests which achieved results well in excess of the new build standard. Airborne sound test results ranged from 49 dB (DnTw+Ctr) to 61 dB (DnTw+Ctr) and impact achieved 46 dB (LnTw), 16 dB better than the required new build standard.
