Hush Acoustics was tasked with providing an acoustic separating floor solution in an extensive material change of use project in Southall. Phoenix House was being converted by Vascroft Construction from an office building to residential flats, in a project which involved building into the basement, adding two floors and expanding at the rear.The development of 149 flats, each of which comprises 2 bedrooms, 1 ensuite, 1 bathroom, 1 kitchen/living area, required an effective design for the separating floors to ensure they would be effectively soundproofed throughout across multiple different floor finishes.After assessing a number of floor construction materials, Hush Panel 28 floating floor panels were selected to meet the acoustic performance targets. Using this panel meant that throughout the bedrooms and living areas a simple underlay could be laid before the finished carpets or engineered timber floor were installed. Hush Panel 28 was also suitable for the floors in the wet rooms and entrance hallways by applying Detromat on top of the panel to form an anti cracking surface.A team of more than 100 operatives worked on site, with every 1000 sq. m of floor completed per week, which Hush Acoustics supported to ensure Vascroft could meet the project’s strict delivery schedule.

New Era was specified to provide a high level of acoustic isolation for this 3000m2 residential project in Fitzrovia, London

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.

The SiteExCel London opened in November 2000 and was the integral component of a huge regeneration project in the area of the Royal Victoria Docks next to the River Thames. The Phase 2 project had the primary objective of increasing the existing flat floor space by 32,500m² resulting in an incredible one million square feet of flexible floor space. This projected the already highly regarded Excel  London into the position of a world class exhibition and conference venue.  Close to London City Airport and with it’s own dedicated station on the Dockland Light Railway the centre manages to attract millions of visitors per year and is a major employer within the local community.The ProjectHaving worked with Sir Robert McAlpine on numerous projects, Bolton Gate Company were extremely pleased to be chosen to again work alongside this Main Contractor particularly on this prestigious project.   The contract initially involved the supply and installation of a range of 30 and 60 minute fire rated shutters to satisfy the requirement for fire compartmentation between different exhibition spaces and to communal walkways throughout the Exhibition Centre. As the fire strategy developed it became evident that, for particular areas including some of the largest openings (7m x 10m), the fire shutters were required to provide fire integrity but this also had to be combined with an acoustic rating of up to 17dB RW. At the time, acoustic rated fire shutters did not exist on the market as a single product solution and consequently it was typical to supply two separate shutters with one to satisfy each requirement but, given space limitations, this was not a viable option. The SolutionDrawing on years of experience, Bolton Gate Company were committed to developing a workable solution in order to fully satisfy the project requirements.  Moving away from the standard ‘single skin’ type fire rated rolling shutter, efforts were concentrated upon manufacturing a new insulated type shutter that would be capable of providing the acoustic rating. The new shutter design was subjected to a series of rigorous testing, include both fire and acoustic tests all of which were in keeping with the very latest standards. The testing proved to be highly successful and we were pleased to complete our contractual obligations using the very first Fireroll Acoustic shutters which had achieved an E120 fire rating and 22dB RW acoustic rating. The Fire Shutter - Fireroll Acoustic provided a compact, hard wearing, yet aesthetically pleasing single shutter solution which was entirely suitable for incorporation into such a highly regarded exhibition and conference centre.

The Leicester FC state-of-the-art £100m elite sports training facility occupies a 185-acre site in Seagrave, Leicestershire. Designed by KSS Architects, a world-leading specialist in the design of major sports venues and training centres, the project was a core aspiration of the club’s Chairman Vichai Srivaddhanaprabha who tragically died in 2018.The training centre is regarded as one of the most advanced in Europe in terms of its quality, scale and sustainability ambitions. KSS specified Rockfon® Mono® Acoustic – a seamless acoustic ceiling – for key areas throughout the site. Son of Khun Vichai and current Leicester City Chairman, Aiyawatt Srivaddhanaprabha, “A new training ground has been a dream many years in the making, so it is with great pride that we have been able to deliver this. Seagrave will be a pivotal part of the club’s operation for generations to come.”Rockfon Mono Acoustic – the perfect matchAround 430m2 of Rockfon Mono Acoustic ceilings are installed to ensure optimum sound control while delivering a seamless, smooth, aesthetic. Among others, these spaces include the hydrotherapy pool area, the 1st Team changing room and the Owners Suite.KSS Associate Director Lorenzo Pierini, commented, “Rockfon Mono Acoustic was the clear choice for use throughout these spaces as it gave us the contemporary, minimalist look we wanted, while meeting the demanding acoustic control required.”The ultimate alternative There are several acoustic ceiling options available but for the ultimate in looks and sound control, an acoustic render provides the perfect solution. With Rockfon Mono Acoustic, the ceiling tile substrate is installed and then finished with a specialist acoustic render to create a seamless surface. Mono can be used for ceilings, walls, or to create bespoke islands. Its versatility means it can be used to form curves, easily transitioned into plasterboard or integrated into existing mouldings. Outstanding performance Mono achieves Class A sound absorption and Class A2 fire protection whilst delivering 87% light reflection and greater than 99% light diffusion. Thanks to its core of naturally occurring, non-hygroscopic stone wool, it provides no sustenance to harmful micro-organisms, embodies high humidity resistance and is impervious to most environmental pressures. It is Bronze level Cradle to Cradle Certified® and can also contribute valuably to LEED, BREAM and WELL Building Standards.Installation courtesy of Pacy & Wheatley. Pacy & Wheatley Director Craig Wheatley, “The scale and ambition of this project is truly epic. As with the majority of modern developments, large windows, stone, structural steel and other resonant architectural elements can generate unwanted sound. That’s where Mono Acoustic really scores as it does not necessitate a compromise between style and sound control – a win win – if you will. Its flexibility meant we could seamlessly integrate linear and spot lighting at Leicester and neatly incorporate hatches for easy access to the services above. In the pool area the system also enabled us to elegantly transition into plasterboard perimeter upstand abutments.”The wider masterplan The training ground masterplan includes the Vichai Srivaddhanaprabha Building, which houses the primary training, medical and administrative hub. There are twelve full-size pitches, a show pitch with a 499-seat stand to allow academy teams to play in a match environment, The King Power Centre – the site’s central point, housing a full size indoor pitch and media centre that moulds into the landscape, an integrated training centre for first-team and academy squads including fitness and hydrotherapy suites, tactics, media, dining facilities and a nine-hole recreational golf course. McLaren were appointed Main Contractor at Seagrave and were responsible for leading the project. Senior Project Manager at the firm, Simon Ruddick, “The unrelenting progress of this project from day one was a testament to our continued ethos of partnering with key customers, and working to overcome delivery challenges... We have overcome some of the most challenging weather in recorded history too, and of course restrictions due to the COVID-19 pandemic.”McLaren Managing Director, South, Jay Newman, “It has been an honour to partner with Leicester City to deliver their new training facility, set to shape the players of today and tomorrow. Building on our considerable experience in sports and leisure, Seagrave has become one of the most modern training facilities in Europe.

Acoustics are a particular issue in swimming pools due to the large areas of tiling, and because water itself is also highly reflective of sound. Hawkins\Brown architects needed a material that would provide high performance sound absorption whilst being compatible with the specialist environmental conditions of a pool. As this is within a school, speech intelligibility is of particular importance for learning – and the BASWA discretely provides this crucial function. BASWA was chosen for its high acoustic performance and system quality including the marble surface coating, which may be used in high humidity environments as standard.

Hush Acoustics provided the acoustic floor and wall solutions for a development in Ellesmere Port, Cheshire involving the conversion of a former Woolworths store turned snooker hall, which was being transformed into a ground floor sports shop with nine first floor apartments above. In addition to meeting the acoustic performance requirements, the client was also keen to ensure the design would meet the fire regulations required.Following a site visit, the Hush HD1030 system was specified for the separating floors. This is compliant with UK Building Regulations Approved Document E and is suitable for refurbishment projects with timber structures that incorporate lath and plaster ceilings – all with the benefit of a 1-hour fire resistance at ceiling level.We worked closely with EH Building Contractors to ensure the HD1030 acoustic floor system was installed to the required standard. For the separating walls, Hush Twin Frame Metal Stud Party Walls were installed onto the plywood structural floor and isolated using Heavy-Duty Isolation Tape. The stud walls were insulated using the Hush Slab 100 Sound Absorber, ensuring the cavity between the two stud frames were kept clear.The client had initially discussed keeping the original existing lay in grid ceiling within the shop, however, in order to achieve outstanding acoustic performance, the majority of the perforated metal panels from within the lay in grid ceiling had to be removed. Some of the original ceiling could be retained, however, with higher performing ceiling tiles used to replace it in other areas, maintaining the original features as per the client’s request.Once completed, acoustic testing was carried out on site to determine the success of the acoustic design and installation. First of all, the twin metal stud wall was tested, which achieved an airborne performance of 56db (DnTw+Ctr). An airborne sound test was then conducted between the sports shop and one of the first floor apartments which showed a performance of 47 dB (DnTw+Ctr).All of the acoustic performance goals were achieved without any significant ceiling treatment and our client was happy with the results.

Hush Acoustics were tasked with providing a solution to reduce an impact noise issue on the upper floor of a luxury five-bedroom detached home in Knutsford, Cheshire.Home to a professional football player, the issue stemmed from the noise on the flooring of his snooker room. Impact noise from footsteps when using the room was generating nuisance noise within the living area directly below, which was making it difficult for others in the family to enjoy this space.Working with Short Construction, building contractors based in Wilmslow, Hush supplied 167x sheets of our Hush Panel 33 to solve the issue. This is a versatile, high performing acoustic flooring which is widely used in timber construction, making it ideal for the timber separating floors in this property.With a combination of our eco-friendly acoustic felt and our rubber barrier mat, the Hush Panel 33 performs to all UK Building Regulation requirements as well as the Robust Detail performance targets for timber frame developments. Its unique composition makes it easy to install and quick to use.The product works by creating a high mass barrier and isolating the floor finish from the structure. As the nuisance noise issue in this situation was due to impact noise, it was key to introduce a high performing acoustic floor product to break the connection of the floor finish from the structure. This, in turn, improved the impact performance of noise transmission through the floor structure, giving the client the desired effect and enabling him to use the snooker room as intended.

Tudor House was opened as the offices for Hatfield Rural District Council by the Marquess of Salisbury in 1930. A grand old building, it was built in a Georgian style with a host of period features.When its purpose as a public administration building was over, a proposal for a conversion (material change of use) into apartments was put forward by Lioncrest. Whilst not a listed building, they proposed to retain all of the period features and, where time had taken its toll on the building fabric, restore and renovate the brickwork and stonework back to its former glory.Permission has been given to convert the offices into seven new luxury apartments comprising of four two bedroom apartments and three one bed apartments. The largest apartment was constructed in the roof space which entailed reconstructing the existing roof incorporating two large dormer windows and five roof lights. The building includes a large basement which was converted into stores for the occupants and for each of the apartments to have an allocated car parking space.Lioncrest consulted with Hush Acoustics at the design stage of this development for soundproofing advice and assistance with the design, specification and supply of the materials needed.There were a number of design issues to take into account due to the history of the building and the period features. Our soundproofing experts worked closely with Lioncrest to develop the most economical and convenient acoustic system to achieve the high results sought. The detailed and careful installation of the Hush materials allowed some fantastic sound reducing results giving the owners of the apartments a very good standard of living.A variety of products were combined to achieve the necessary sound reduction throughout the building’s separating floors, ceilings and walls. These included Hush Panel Cem 28, Hush Slab 100 Sound Absorber, Hush Seal 20 perimeter strip, Hush Bond Panel Adhesive, Hush MF Ceiling System and Hush Acoustic Hangers.Through detailed planning from Lioncrest with regard to the schedule, Hush Acoustics were able to deliver all acoustic materials to site ensuring that the deadline for completion was met. 

The project at 83 East Street involved converting an existing office facility into 16 new flats.Soundis was tasked by the main contractor, Innovate Space, to supply an acoustic flooring system in order to provide a comfortable atmosphere for residents to live in and to comply with Approved Document E of Building Regulations.After examining the project, we recommended two different flooring options. The main contractor opted for the option that resulted in a faster installation time.Soundis supplied and our installation partner UK Acoustic Systems installed a Soundis dry screed acoustic flooring which was a high quality, interlocking flooring system using gypsum fibreboard technology, in order to provide a solution for soundproofing difficulties, effectively and efficiently.

Optimising acoustic comfort within radiology facility, LondonHush Acoustics transformed the acoustic environment within a radiology facility where staff and clients experiencing noise nuisance within both a boardroom and video conferencing room, which was noticeably affecting speech clarity.Renowned as specialist consultants throughout the UK, Australia and further afield, offering 24-hour radiology reporting, Everlight Radiology offers urgent after hours and daytime consultant radiologists to hospitals throughout the world. Hence, it was imperative that their rooms were treated quickly in order for the practice to continue with their duty of care and excellent service.After considering printed acoustic boards from another supplier, which would have offered Class C absorption, Everlight’s chief executive officer contacted Hush to gain more specialist advice on sound absorption.Upon a visit to the Everlight Office, we found the rooms to be suffering from very high levels of reverberation and echo noise. Through our professional and technical advice, along with carrying out an acoustic assessment, we presented the client with a recommended solution based around Hush Absorber Panels 50 & 50A panels. The reason for including the Hush Absorber 50A panel in the specification was because it was imperative for the ceilings to be treated in order to get the sound result that our client was anticipating.Faced with a vast array of asymmetrical ventilation ducts and lights on the ceilings in the rooms in question, additional consideration was needed regarding the placement of the acoustic panels. A plan was drawn up to give possible layout options, which were agreed by the client.Unlike the client’s initial consideration prior to contacting Hush, Hush Absorber Panels are Class A absorbers, made from fabric wrapped 50mm thick acoustic foam. They have built in support frames to allow for bracket fixing, to provide an air void behind the absorber for enhanced acoustic performance. Class A absorption is of the highest level, with Class E being the lowest and this scale ensures simple comparison between acoustic products, which is important when choosing the right product for maximum impact on sound reduction and speech clarity.Included in the client’s brief was a request for particular panels to be printed. The client wanted to incorporate their brand logo and hero statements, intended to remind their clients and staff members using the room of their key messaging and values. The pictures supplied to Hush were designed in-house and delivered in high resolution which ensured an outstanding result.The client expressed interest in having larger boards for the video conferencing room to the bespoke sizing of 2050 x 1300 x 50mm. These panels were made to order, and provided in colours Chrome and Smoke, which were then organised in a checked pattern on the ceiling. Hush 50A Absorber Panels were installed using suspension packs, which allows for the air void behind, whereas the Hush Absorber 50 Panels were installed using the Hush Absorber Adhesive, making them clean and easy to install.The client was delighted with the finished result, not only in terms of practically and the acoustic improvements but aesthetically too. The colours chosen along with the custom printing reflects the business looking smart, clean and contemporary and resolves the reverberation issues that they were originally facing.

The Koningin Elisabethzaal in the northern Belgian seaport of Antwerp is unusual in every respect. Located at the heart of an architecturally charming city, structurally merged with a world-famous zoo, and boasting an immensely varied history as a concert hall, it transformed from an acoustic ugly duckling into a gleaming swan of aural experience. At the core of this metamorphosis is the design by the renowned American acoustician Larry Kirkegaard, who completely remodeled the hall acoustically. Golden metal fabric by GKD – GEBR. KUFFERATH AG (GKD) plays a key role in his concept. The woven texture really underlines the one-of-a-kind spatial experience in its use as large-scale cladding for ceiling, walls, and balustrades.One of 65 participants in an international competition to redesign and remodel the Koningin Elisabethzaal, the consortium comprised of SimpsonHaugh Architects (London) and Kirkegaard Associates (Chicago) produced the winning design. Kirkegaard’s ambitious concept, which employed structural and technical agility to aim for nothing less than a world-class standard for the new concert hall, played no small part in this success. The original hall was opened in 1897, served as a hospital ward during the First World War, morphed into a venue for boxing and wrestling matches during the Olympic Games a few years later, and was reopened in 1960 following major destruction in the Second World War. The fan-shaped design of this building, which was not intended to be used purely as a concert hall, contributed greatly to its poor acoustics, which achieved only six out of ten points on the rating scale. Plus, although it provided a stage, there were no rehearsal rooms for the orchestra and soloists. One aim of the new building was therefore to finally offer a home to the Antwerp Symphony Orchestra. The new Koningin Elisabethzaal is the centerpiece of the Elisabeth Center, which was also newly built as an ultramodern 25,000-square-meter conference center. When redesigning the concert hall, the planners decided to reduce its size in order to optimize the acoustics. This resulted in an enormous light-flooded foyer with atrium in the Elisabeth Center. Architect Ian Simpson embedded the new building into the historical complex in such a way that the art nouveau façades that had previously been hidden by the building were revealed once more and the old halls remained largely untouched. One of these halls, the Loos Hall, connects the new 2,000-square-meter concert hall with the historical part and also serves as the foyer of the Elisabeth Center. With its high stuccoed ceilings and rich marble decor, it provides a representative space for exhibitions and receptions. The new four-story building comprises various conference and meeting rooms for up to 1,900 participants, the concert hall with a capacity of 2,000 guests, extensive logistics facilities, VIP and catering areas, administrative offices, and soundproofed rehearsal rooms.An acoustic embrace in a shoe boxThe designers selected a shoe box shape for the concert hall, which classical music lovers deem to be a guarantee of optimum acoustics. This is aided by a perfectly balanced distance between the stage and the wall and an unusual seating arrangement in the parterre and the two galleries. Doing without a permanent apron also prevents a loss of sound. A curved wall means that the largest distance between the stage and audience seats is 30 meters, so that every guest feels part of what is happening on stage and can see and hear equally well from all seats. Movable reflectors clad in metal fabric and suspended from the ceiling as well as frames covered in the same fabric ensure that the sound is able to unfold throughout the entire hall. At the same time, the semitransparent membranes conceal the bare ceiling and the technical installations above. In designing the walls, Kirkegaard Associates chose a wave-shaped oak wainscoting. The cavities were filled with lava sand to prevent vibrations. With this construction, the acousticians drew on the sound experience of earlier concert halls, which employed arm-thick stone walls to reflect low-frequency sound back into the hall. As such, the walls and the rear wall of the stage in the Koningin Elisabethzaal form an acoustic embrace which ensures that the echo is not absorbed but is fully reflected to the stage.Metal fabric for good soundThe same fabric that was used for the ceiling elements also covers the movable reflectors on the back wall of the stage: gold-colored powder-coated Alu 6010. For the ceiling and stage wall, GKD fitted a total of 204 frames, some of them wave-shaped, with 1,600 square meters of this fabric type. Four-meter-long and 2.50-meter-wide panels were fastened to the frames provided by the customer with thin stainless steel wires at intervals of ten centimeters. GKD also incorporated the cutouts for the lights exactly according to the specifications. A first for the weave specialists was that the entire construction consisting of frames and fabric was then coated in the desired shade of gold. This required special pretreatment in order to ensure homogeneous coloring of the components made from different materials – steel and aluminum. Prior to selecting the material, Kirkegaard Associates had carried out extensive tests on the GKD fabrics in order to achieve the best possible sound and space experience. As such, GKD was involved in the planning process with architects and acousticians from a very early stage. The decisive factor in opting for metal fabric was the acoustic neutrality. In addition, the exclusive look, flexibility, and robustness of the GKD fabrics corresponded to the ambitious design concept. That is why the fabric from GKD – Omega 1520 with gold-colored coated weft – was also chosen for the balustrades of the galleries. It fits flexibly to the bidirectionally curved corners of the balustrade and is also resistant to impact thanks to tensioning in the direction of the cable. When fitting the front and rear of the balustrade elements with 400 square meters of this fabric type, the curve needed to be followed exactly. GKD selected a slightly conical panel cut for this purpose in order to realize the radius by tracing a polygon.The clever interaction between the design of the hall shape, ceiling, wall, and balustrade is what gives the new Koningin Elisabethzaal its excellent acoustics: with 9.3 out of 10 points on the rating scale, it is considered almost perfect. At the opening concert, Belgium’s Queen Mathilde personally handed over the hall, which offers a world-class space and sound experience, to the public.

Hinchley Wood School in Esher, Surrey is a mixed comprehensive academy, providing education for 11-18-year olds. They tasked Hush with a project to improve acoustic comfort in their sports hall following the success of a previous project to install Hush Absorber Panels within their canteen in 2016.Mike Robeson, Director of Finance and resources at the school, contacted us regarding their purpose-built Sports Hall in which they were experiencing severe reverberation issues. The Sports Hall has been in use for many years to carry out PE lessons and other sporting activities, along with being used as an Examination Hall.When being used for exams, the school were having to temporarily lay a carpet on the floor to dampen the sounds within the hall, hoping to create a calming and relaxing atmosphere with minimal echoes. However, this was unsatisfactory, and they sought an effective long term solution.When conducted a site visit which enabled us to measure the Sports Hall to be 8.5m in height, 27m in length and 18 m wide. The ceiling area features metal trunking around it and measures 486 sq. m in total. We calculated that 230.4 sq. m would need to be acoustically treated.In order to effectively treat the reverberation issues within the area, we specified 192x 50mm Hush Absorber panels to make the hall acoustically fit for purpose and they would need to be directly bonded to the metal deck.The panels that we supplied the school were from our new Polysorb range, in which the product itself is made from polyester as opposed to foam, giving equally excellent acoustic results. We also supplied these panels with a hard face material, to be damage protected from any equipment which may make its way up to the ceiling.The Polysorb panels are manufactured from 100% recyclable Polyester, in which a minimum of 45% is from post consumer waste PET (Plastic Bottles). The panels have been designed for exceptional sound absorption qualities, whilst being light-weight, impact resistant and durable. These panels can also be cut to any required size and finished in your chosen design.We allowed 5 working days to be able to fit the panels and were able to finish within 4. Whilst installing them, we also rescued 12 footballs and a whole host of shuttlecocks from the ceiling area!We are pleased to have been able to help the school with their reverberation issues and to make a positive impact on the pupils learning, as well as making for a more appropriate and less noisy exam hall.

Harbour Light Assisted Living CIC housing association approached Hush Acoustics to upgrade the floor within one of its flats to offer a higher level of soundproofing in line with the specific requirements of one of its tenants.The housing association, which specialises in providing bespoke accommodation and services to assist people with disabilities to fulfil their responsibilities as tenants and help them live an independent life, sought to improve the acoustic performance of a separating floor in the flat for a new resident. The individual suffered from an Autistic Spectrum Condition (ASC), also referred to as Autism Spectrum Disorder (ASD), which meant any flooring solution had to be appropriate for their needs, not only to reduce both impact and airborne ‘noise nuisance’ encroaching to the flat below, but also to ensure the final floor finish could be fully bonded to the acoustic substrate. The potential noise issues were regarded as higher than typical domestic noise which meant a more robust specification was required.The solution was provided by Hush Mat 15 with Hush Ply 28 overlaid. This provided the required mass, flexibility and isolation, as well as a robust surface to allow the floor covering to be directly bonded, ensuring it could not be lifted.

Soundis were required to supply and install the Absorb-R GypLine αw acoustic plaster to the underside of the central staircase and to various meeting rooms around the BSKYB TV Meeting Centre.Offering unrivalled levels of sound absorption...The project presented challenges, programme constraints and critical interfaces with Mechanical & Electrical trades all of which were dealt with by the site and installations team in a professional manner.The Absorb-R GypLine αw finish offers unrivalled levels of sound absorption but also ensures walls and ceilings are clear of panels and visible acoustic solutions, providing a virtually seamless monolithic surface for walls and ceilings in a choice of RAL colours.This was ideal for the BSKYB project team as it complied with all of their requirements and expectations. Soundis along with our installation partner UK Acoustic Systems have completed numerous similar projects using the Soundis Absorb-R GypLine αw Acoustic Plaster.The Absorb-R GypLine aw system achieves the “best” aesthetic finish possible with a range of finishes available. Absorb-R GypLine αw is now being specified and utilised in a large number of office, hotel and leisure projects throughout the UK.

An additional two-story extension to the side of the main building will form a new restaurant and additional rooms.Old Granada Studios is a true Manchester landmark; a building brimming with heritage and history. The re-invention of this famous building will create a place where people come together to work, stay and play. It will be a new cultural destination for the city. It will be a culture of cool places, a world-renowned hotel, studios, workspace, food and drink.The old Granada Studios is anchored by the internationally renowned Soho House Group with their stylish members’ club, restaurant, bar and the new concept Mollie’s Motel. The iconic studios have also been modernised and activated by Manchester Studios with the best production and broadcast facilities in Manchester, they are once again the city’s leading creativity complex for TV, film, music and digital content.Soundis supplied of an area approximately 7,000 sq meters, across 9 different levels which consisted of various flooring build ups.  Systems included, the Soundis Cradle & Batten Acoustic Flooring System to help improve both airborne and impact performance, this system is also compliant with Robust Details FFT2. Overlayed were the Soundis Dry Screed Panels; applied to level the structural deck to minimum of SR2 Standards. Another flooring system we supplied at this project was the Soundis CineSystem Ultra Floor offering many additional acoustic benefits. This system also offers the greatest strength, whilst the large dead load that the floated slab provides, ensures minimal movement under the addition of any live loading.

The ChallengeLocated in a densely populated area of London, the Balham branch of Waitrose had a responsibility to minimise the impact of its operations on the surrounding neighbourhood. Supermarkets are deceptively noisy, a solution was required in order to maintain low noise levels within the proximity of the store.Closely monitoring store activity, Waitrose identified that deliveries risked causing a disturbance to nearby residents – because metal cages used to carry stock generated high levels of noise when rolling across the uneven concrete floor, particularly when empty.To reduce noise levels during delivery times, Waitrose needed a durable acoustic flooring solution that would directly attenuate sound and withstand the impact of the cages. This was where CMS Danskin were able to step in and provide a valuable and reliable solution.The SolutionAfter reviewing the performance requirements of the store, CMS Acoustics recommended and installed High Impact Mat. Manufactured from a non-reflective and slip resistant material which exceeds the highest safety standards, CMS High Impact Mat reduces excess sound by cushioning and absorbing impact sound.Composed of reclaimed rubber, EPDM granulate and PUR binder, CMS High Impact Mat is an environmentally friendly product available in a range of thicknesses, from 4mm to 12mm. At Waitrose, the material was specified at a thickness of 10mm.The ResultQuick and easy to install, CMS Acoustics completed the 150m2 installation of High Impact Mat in just two days. Critical to minimising disruption to store operations, CMS High Impact Mat was able to carry traffic just 24 hours after installation.Waitrose branch manager, Steve Baller, commented: “As part of our commitment to minimise disruption to our neighbours it was important to find a product that would reduce noise. CMS High Impact Mat has proven to be an excellent product, the sound levels have been reduced substantially and the floor is able to withstand the weight of loads coming into the warehouse.”

In 2015, Quinn London Ltd started the refurbishment of The Market Building, in Brentford which involved the conversion of Offices to residential dwellings as a ‘Material Change of Use’ project. Soundis provided acoustic solution options for this project, in order to ensure a cost effective Value Engineering Exercise, on behalf of the Main Contractor.As the 1st floor required a deep void system due to new soil pipes and waste pipes having to be installed along the corridor within the building for kitchens and bathrooms, it was agreed to utilise Soundis Cradle & Batten System. This provided a service void for the pipes of 300mm whilst the other areas of the floor were treated with the system at 80mm FFH. The Soundis cradle & batten acoustic floor was then overlaid with a Soundis a high quality, interlocking dry screed system gypsum fibreboard.The Soundis cradle & batten floor system has been installed on the existing concrete and existing timber structural floors to provide a level floor over the un-even sub-deck. The service void provided by Soundis cradle & batten system can be used for other flooring applications, such as underfloor heating.Our Cradle and Risers are manufactured from 100% recycled materials assisting to the sustainability targets of projects.

A leading supermarket in Leicestershire situated near a flourishing housing development came to the attention of local residents when the noise associated with the running of a major mixed retail outlet became too much by the constant flow HVG. Jacksons employed multiple solutions for this issue including - Installing a large 13.2m Acoustic gate with a 9m opening and a smaller single leaf automated swing gate with Acoustic fencing which helped to reduce noise levels from running components within the supermarket delivery area.

When American architect, Louis Sullivan, in 1896, said, “Form ever follows function” he probably hadn’t foreseen the creation of the Statutory List of Buildings of Special Architectural or Historic Interest that would have its origins in the devastation left in the wake of the Second World War.The ChallengeThe preservation of old buildings is challenging enough but additional issues arise when it comes to refurbishments and renovations, particularly if there is a material change of use. Suddenly, a building that was created for one purpose is given another, sometimes radically different, purpose. The form can’t follow the function if the function is allocated post-construction. Significant modifications can help align an old building with its new function but, in the case of Grade II listed buildings, for example, the interior can’t be fundamentally changed and function is forced to compromise.Even when there is no significant change of use, modern building regulations demand performance standards that didn’t even exist at the time that buildings currently being renovated were originally envisioned and created. The requirements of Part E of the Building Regulations, governing soundproofing between floors of a building, are relatively easy to shoehorn into a renovation project as these tend to be concealed beneath floor finishes and screeds. Problems with reverberation are far more difficult to tackle and even though there is very little regulation surrounding this issue, BB93 of the Building Regulations, governing reverberation levels in schools, tends to be employed as an effective benchmark.When reverberation levels reach a certain point, they can become more than just an irritation, with the overlap between what is currently being said and what was said a couple of seconds ago becoming genuinely disruptive. In schools, this can make it extremely difficult for children to follow what their teacher is saying. For this reason, BB93 demands a reverberation time of 0.8 seconds or less, with 0.4 seconds being seen as ideal. Reverberation time is described as the time taken for the sound pressure to fall by 60 decibels after the original sound has ceased abruptly. So, in the case of BB93, 0.8 seconds or less after a sound has been made, that sound should have decreased by 60dB. 60dB is a significant drop, the difference between a construction site with pneumatics drills and a busy department store.It is in situations like this, when form and function appear determined to have nothing to do with one another, that architects and the designers of construction materials are driven towards increasingly innovative and paradigm-shifting solutions. The stereotype of the architect who is concerned only with form and is completely disinterested in function is, thankfully, a thing of the past (if these individuals ever really existed at all). Modern architects don’t create buildings so much as living and working spaces, where physical aesthetics are neatly balanced with a host of other concerns, such as the quality of an environment’s acoustics.Although regulation sets crucial, legally-enforceable parameters, few architects need to be incentivised to aim high when it comes to a building’s acoustics.This drive towards innovation has resulted in widely differing solutions. Reflector panels and diffusers redirect sound waves or disburse them more evenly through the listening environment, reducing nuisance noise. These solutions tend to be employed in lecture halls or auditoria, where a certain amount of volume is desirable, but the quality of the sound is crucial. The most commonly employed anti-reverberation product is the sound absorption panel. These fabric covered panels are mounted on the walls of a room or suspended from the ceiling. When the sound wave enters the open cell structure or fibrous composition of the panel, it bounces around like a pinball. The friction resulting from each instance of impact is converted into low-level heat which is absorbed into the material. When the sound wave re-emerges, its energy, and consequently its ‘loudness’, is significantly diminished. This tends to be the solution of choice for classrooms and is generally considered to be the quickest and most cost-effective route to BB93 compliance.Some acoustic challenges are more demanding than others. The renovation of the Picton Reading Room, part of the £50 million redevelopment of Liverpool Central Library, being a case in point. Not only is the reading room contained within a Grade II listed building, it also boasts an elaborate coffered saucer dome. Domes are something of an acoustician’s nightmare, as they focus rather than distribute sound, exacerbating reverberation problems. All of which means a dropped pencil in the Picton Reading Room sounds like a Keith Moon drum solo. Why Cornelius Sherlock, the reading room’s architect, decided to incorporate a dome – one 100 feet in diameter and 56 feet high – into his design for a space that was intended for quiet study is a little bewildering, even if his work does predate Sullivan’s remarks by a couple of decades.Thousands of hours of work have gone into restoring the ceiling of the Picton Reading Room, with plaster, paint and gold leaf being matched as closely as possible to the original 1875 design. Given the need to be true to the form of the original, certain anti-reverberation solutions were unworkable. Reflectors, diffusers and baffles couldn’t be suspended from the ceiling, as all those thousands of hours of work would be hidden from view and the Nineteenth Century aesthetics undermined. Wall-mounted sound absorption panels were not a viable option, as there was very little wall to speak of, with three levels of solid wood bookshelves encircling the room, almost up to the beginning of the dome.Recent innovations in the area of acoustic plaster held the solution. Sound absorbent plaster has been around for some years, offering a smooth appearance which conceals a porous, granular structure similar to that found in sound absorption panels. However, until recently, the amount of sound absorption offered has always been limited to Class ‘B’ and Class ‘C’. Now, however, Class ‘A’ acoustic plaster systems are available. It was just such an acoustic plaster that CMS Danskin used for the Liverpool Central Library project.Because of the limited surface area in the Picton Reading Room, Ellie Morris, CMS Danskin’s Technical Support Coordinator, hit upon the idea of applying the acoustic plaster into the soffits beneath the balconies of the upper shelving areas. The results were a resounding (or un-resounding) success. A relatively small amount of an innovative product, cleverly applied brought a 138-year old listed building’s acoustics in line with contemporary standards and not a hint of compromise in sight.

Belonging to the hospital and the University of Medicine of Rotterdam, the Erasmus medical centre is an internationally recognized centre of excellence. As a learning centre, the building of 16 000 sqm contains a central lobby, conference rooms, learning rooms and offices, on 3 stairs. It welcomes more than 400 working or learning desks. Thank to the spectacular ceiling, the central lobby is very bright and spacious. 4500 m² of acoustic stretched ceiling has been installed to improve the sound comfort. Architect : Claus en Kaan

When CMS Danskin Acoustics Limited was engaged by Progressive Group to ensure the Shangri-La Hotel’s 42 floors in the Shard were effectively soundproofed, it wasn’t a straightforward assignment. From the very first sketches drawn on a napkin by Piano during dinner with entrepreneur and property developer Irvine Sellar, the Shard was always intended to be ‘all about the windows’, with expressive façades of angled glass reflecting sunlight and the sky, and affording 360° views of the city.Unfortunately, when the glazing is central to the design, floors can get in the way of the overall effect, and the temptation is to minimise floor heights (within Building Regulation parameters, of course). This presents a significant challenge to acoustic insulation installers. In short, the thinner the floor, the harder the soundproofing material has to work acoustically and the more physical punishment it has to endure.For approximately 70% of the floors, Progressive applied a Gyvlon liquid screed at a 40mm minimum thickness. The screed was pumped from ground level, with the largest pour in excess of 80m3 covering an area of 1,680m2. In approximately 30% of the floor areas, however, the floor screeding level could not be raised because of the existing floor-level transom in the curtain walling. This meant that there were instances of screed thicknesses of approximately 25mm in places.CMS Danskin’s Regupol E48 (REGUPOL sonus curve 8) was specified, a Robust Detail approved (E-FC-6) high-performance screed isolation material. E48 (REGUPOL sonus curve 8) was perfect for those ‘thin screed’ areas, with its maximum load bearing capacity of 3000kg/m3 (30kN/m2), combined with a mean average impact sound insulation performance of 46dB and a mean average airborne sound insulation performance of 49dB, both values well in excess of the requirements of Part E of the Building Regulations.Building Regulations aside, E48’s (REGUPOL sonus curve 8) ‘over-performance’ is crucial for a hotel as exclusive as the Shangri-La. The award-winning, globe-spanning hotel group prides itself on providing a customer-focused experience, with the emphasis very much on luxury. Intrusive noise from above or below a guest’s accommodation would almost certainly undermine those efforts. Plus, with this being a flagship project for the Shangri-La – their first hotel in Europe – ‘fit for purpose’ simply wasn’t an option.As a Robust Detail underscreed, E48 (REGUPOL sonus curve 8) has already been rigorously pre-tested to ensure it achieves a minimum performance of 5dB over and above Part E, thus eliminating the need for Pre-Completion Testing. However, CMS Danskin and Progressive, having worked together successfully on the exclusive One Hyde Park development, preferred to adopt a partnership approach, with the emphasis on planning and testing, giving absolute certainty to all parties and making full use of all the skills, expertise and experience at their disposal. To this end, Paul Absolon, CMS Danskin’s Technical Director, worked closely with Progressive’s technicians, carrying out off-site simulations and fitting trials with varying screed thicknesses. Only once both parties were satisfied with every aspect of E48’s (REGUPOL sonus curve 8) acoustic performance in a ‘real world’ situation did the installation proceed.More than 16,000m2 of E48 (REGUPOL sonus curve 8) were installed over approximately 3 months, with Progressive and CMS Danskin maintaining their close working relationship throughout.Tony Cooney, Estimating Manager at Progressive Group, said, “The completion of the screed and insulation work on the Shangri La Hotel development was a fantastic achievement and it presented a number of very challenging situations – both technical and logistical. Solutions to these challenging situations are achieved by the co-operation of all parties involved – including material suppliers. The technical assistance provided by CMS Danskin on this Shangri-La project and other prestigious contracts in the London region in recent years has been exceptional and we look forward to continuing our excellent relationship.”Said Paul Absolon, “It was a privilege working on a project as ground-breaking and culturally significant as The Shard, and it was a pleasure working with the professionals at Progressive Group again. At CMS Danskin, we like to be put to the test. The Shard certainly was a challenge and we’re proud to have met that challenge and delivered.”

Efficient Approach Dramatically Reduces Turbine Noise at CCGT Power StationsTen years after it was first used at Uskmouth, this innovative approach to soundproofing that reduces insulation depth by up to 76%, is once again commissioned in France.Dangerous Levels of NoiseModern dry cooling systems offer many benefits over traditional systems in CCGT power stations, but they have the disadvantage of being a complex source of noise transmission. The turbine noise recorded coming from the dry cooling system at the Severn Power CCGT Power Station at Uskmouth was between 130dB(A) and 135dB(A). Exposure to these levels of noise, a full 50dB above The Control of Noise at Work Regulations 2005 “upper action level”, will cause both immediate and permanent damage.When acoustics and soundproofing specialist, CMS Danskin Acoustics, were brought in by SPX Cooling Technologies, designers of Uskmouth’s dry cooling system, they discovered not only high levels of noise but also that the noise generated had a very low-frequency bias, the most difficult noise spectrum to treat.Solutions for low-frequency noise issues typically involve wrapping the problem in significant quantities of acoustic insulation, with many standard solutions being as deep as 500mm to 700mm. The sheer volume of lagging required for an insulation-based approach to a project like Uskmouth, with 8,000m2 of ducting to be covered, would be expensive, time-consuming to install and prohibitively disruptive.The New Approach proven at UskmouthThe challenge of producing a soundproofing system that would be cost effective and efficient to install was taken up by CMS Danskin Acoustic’s Technical Direct Paul Absolon. CMS Danskin has a reputation for effective, high quality acoustic solutions tailored to the specific challenge, and this solution was no different.Exploring the wide range of acoustic materials from the company’s industrial acoustics range, Paul opted for a combination of materials working in concert: the unique CMS HTIB elastomeric isolation pads, constructed from a polyurethane-bound rubber granulate with excellent dampening and isolation characteristics; QuietSlab SVX3, a high-performance, mineral- fibre acoustic lagging; and WBKT Acoustic Barriers, a high-density, barium-sulphate-loaded thermoplastic polymer, which is thin, flexible and easy to work with.By using a bespoke combination of materials which each tackled specific aspects of the problem, CMS Danskin Acoustics were able to create a soundproofing solution with a construction depth of just 170mm, between 66% and 76% thinner than the 500-700mm standard solution. Disruption was minimised and material costs reduced.Once complete, the system was rigorously tested by SPX Cooling Technologies and Uskmouth’s main contractor, Siemen’s Energy. CMS Danskin Acoustics’ solution had reduced the noise generated by 39%, to just 82-83dB(A), under the 85dB “upper action level” listed in The Control of Noise at Work Regulations 2005.Peter Ullrich, project director, Siemens Energy, commented at the time:“Effectively controlling noise and reducing sound emissions was a top priority for us in the Uskmouth project. Not only was it essential that the dry cooling system satisfied all the legal acoustic obligations and regulations but just as important was that neighbouring properties were not disturbed by additional noise levels.”Repeat Success at LandivisiauTen years on, the same successful approach has been applied to the dry cooling system at the new CCGT Power Station at Landivisiau in Brittany, north-western France. Also built by Siemens, the dry cooling system was supplied by SPG Dry Cooling. In the case of Landivisiau, even greater sound reduction was required, from approximately 140dB(A) to below The Control of Noise at Work Regulations limit of 85dB(A).To meet this challenge, SPG and CMS Danskin collaborated on extensive testing at the acoustic testing laboratory of SRL Technical Services. The reductions achieved during testing as part of the specification process were some of the largest reductions in sound ever measured at SRL.Once the specification was confirmed, CMS Danskin worked with SPG to ensure that materials for the multi-layer acoustic solution were prepared and delivered efficiently so that SPG’s installers always had the correct materials on site. The installation of the acoustic soundproofing was completed in October 2021 and the power station entered commission as planned in April 2022.“CMS Danskin Acoustics Limited successfully supplied the acoustic material package for the project which was tested at SRL to give an overall lab test reduction of 68dB Rw.”Robert Hill, Project Manager, SPG Dry Cooling
