In 2019 Inpro were asked by Skanska to tender for an expansion joint product line addressing the exterior cladding of this unique facility. At that time, several other manufacturing companies were being considered for the wide ranging scope of movement joints required. However after in depth interviews, only Inpro was able to offer all the complex joint solutions required in one primary supplier.Detailed Sustainability product information was submitted and verified by third parties.Complicated Shop Drawings and take-offs of the massive 6-building involved depicting multiple complicated transitions between varying substrates, differing products and a range of geometries for the custom-made solutions.Demonstrated our ability to overcome complex technical and field-related problems.Were involved with hours of online meetings with the main stakeholders- Skanska technical teams, the Architectural team and the Installing Contractor in a collaborative approach to implement best practice and minimize risk.This was an Inpro team project including Senior Product Management, Sustainability team, estimation and commercial management who all played an important part to land this iconic development with SKANSKA.

The hospitality industry has been hit hard by the pandemic as visitors, for obvious reasons, have been conspicuous by their absence. Hotel Savoy in Luleå took advantage of the situation by completely renovating the hotel’s restaurant with new surfaces, design and furnishings.The old brick wall in the interior of the restaurant had taken its toll. In order to find a new material that would fit in, they looked for a wooden panel that could also contribute to a better atmosphere in the form of an acoustic absorbing solution. But finding such a product that would also meet the fire requirements of the premises was not the easiest thing to do.We at Gustafs received the request at the same time as we were working on the development of our new product, Lamellow+. In short, the Lamellow panels delivered to the Hotel Savoy in Luleå became a pilot project for the product. The panels installed in the restaurant are made of American Oak wood veneer with a grey gypsum core and Wool grey acoustic felt – a combination that feels natural and minimises the contrasts in the product. The panel was also approved by the fire engineers working on the project, thanks to the natural fire protection provided by the reinforced fibreboard.

A cladding replacement project, Klasse G-board and C-board have both been utilised due to their A1 fire-rated, fully non-combustible classification.

The 2019 Special Olympics Cauldron Abu Dhabi was designed and fabricated in Yorkshire by Stage One Creative Services Ltd. It was then anodised using a selection of colours from our Anolok Bronze range. The anodised panels were then air freighted to Dubai where they were installed to create this magnificent cauldron prior to the opening ceremony. Each county did their own text which was applied underneath the logo using our UnAtex process. The main aim of this project was to ensure the material would be A1 fire rated due to flames being projected from inside the cauldron, hence making fire rating imperative.

The non-profit organization Living Architecture has realised four special holiday homes across England, each one is an extraordinary example of contemporary architecture, designed by leading architects. The most spectacular of the projects is the ‘Balancing Barn’ in Suffolk (Uk), designed by the Dutch bureau MVRDV. In the 30-metre long house, which juts out 15 metres over the edge of a rise, Reynaers CP 155-LS (Lift & Slide) was used for the large sliding windows. The large protruding section meant that it was possible to place another large window in the floor as a complement to the architectonic spectacle.

To extend and refurbish the Luton and Dunstable University Hospital’s Emergency Department. This £14.5 million project included the creation of a new entrance into the healthcare facility to provide the local community with greater accessibility to quality care and critical services

Dacatie's Frame Formers were used in the development of 2, 3 & 4 bedroom homes in the attractive market town of Hinckley.Including a New Primary School, an Amphitheatre, Children’s Play Area, New District Centre, Playing Fields alongside additional landscaped open spaces.

Challenge As part of a major Council Housing refurbishment project Portsmouth City specified the installation of a new vinyl floor covering to all stairwells with new Equality Act compliant stair nosings. The Equality Act offers best practice guidance and recommendations on how to make stairways safe and accessible for partially sighted people. Any new stair nosings for the project would therefore need to feature appropriately sized dimensions, a contrasting band of colour and tactile hazard warning surfaces to assist with user safety.

Floor Furnishings were tasked with fitting flooring in University lecture theatres. The spaces, which would be used by large volumes of people, had to be Equality Act compliant and meet building regulations related to stepped access and slip resistance. Nathan Jefferies, Director of the flooring contractor contacted Quantum to seek technical advice on which Stair Nosings would meet these standards. Quantum provided information on a Stair Nosing that would meet the criteria for this project and this information was passed onto the Architect working on the University buildings.

The ProjectCapital Content is a media content production team based in Cobham. The company provides videos, photography, audio, and various other marketing and branding media for a range of businesses and individuals.Capital Content approached G Harding Flooring, a flooring contractor, to “bring their office to life” with design featured flooring. The company records podcasts, film shoots and other advertising material for clients at their workplace, so the designs needed to match their own vision of how they wanted to be perceived.Glenn from G Harding Flooring carried out a site inspection with the owner of Capital Content, and discussed how to best incorporate their business logos and assets into the flooring layout. This would involve sourcing stair nosings and carpet tiles which would match the colours of the company’s branding.The ApproachGlenn contacted Quantum Flooring to talk about which stair nosings would be suitable for the job. Q-Range DUO Stair Nosings have tread inserts on both the tread and the riser of the profile. This enables the profiles to have either one colour on both or, as with this project, a different colour on the tread and riser for design purposes.Q-Range DUO allowed G Harding Flooring to pick colours for the tread and riser to match Capital Content’s branding and logo. As Glenn says: “We wanted to create a visual ‘wow’ factor to the entrance of the office where visiting clients would be first greeted on arrival – the staircase. Samples of additional colours to match Capital Content’s own branding was a big plus.“By using Quantum’s extensive colour bank, not only were we able to find a perfect match, we found 2! The colours, a bold pink for the tread, and a vibrant blue for the riser, gave the stairwell an abundance of colour that would change as you walked up it.”The OutcomeG Harding Flooring installed the Q-Range DUO profiles using Q-Fix Stair Nosing Adhesive. This has ensured a solid, firm and secure fixing which can withstand the traffic anticipated for the workplace. The stair nosings achieve the aim of an eye-catching entrance to the office, while making the stairs safe and easy to navigate.The branded theme is continued throughout the office, where G Harding Flooring installed hand cut logos and patterns utilising carpet tiles. The results are outstanding, with the offices being an excellent example of G Harding’s flooring design skills, and showcasing Capital Content’s brand and logo.As Glenn from G Harding Flooring says: “The client wanted to show the importance of branding, attention to detail and how to stand out from the crowd as this is a key service they provide to their clients. Where best to start and show off their visions? In their very own workspace.”

The ProjectAlbion Mills is a high-end, purpose-built office complex near Willerby Shopping Park in Hull. It is a two-storey building, with numerous office suites for businesses to utilise.The custodians of Albion Mills planned to revitalise the interior of the offices. The new-look space would need a design with an understated colour scheme, which would be suitable for a working environment. This would include resilient flooring in parts, with carpet tiles adjacent to it. To link the vinyl and carpeted areas, a flooring transition would be needed.The flooring transition would need to bridge the gap between the two floorcoverings, incorporating the different thicknesses of the resilient and carpeted flooring without creating a trip or slip hazard. The design of the new offices called for the transition to be curved into different shapes, meaning that they would need to be suitable to curve on-site.The ApproachFloors Hull were appointed as the flooring contractor for the refurbishment. After deciding on the floorcoverings they would use for the project, they needed a flooring transition that would link the two together. Floors Hull decided that Quantum Flooring Solutions’ TopClip transitions range would offer the best option.TopClip is a range of flooring transitions which consists of 4 uPVC tops, which can fit into 6 different bases; 2 aluminium and 4 uPVC. All of the uPVC bases can be curved to a radius of approximately 750mm. Between them, the TopClip range can transition between practically any different gauge or type of floorcoverings.For the Albion Mills project, Quantum’s QTC42R top was used with the QVB1 uPVC base. This meant that the profiles could be curved into the necessary shapes. In order to get around tight curves, it can help to gently heat the profile with a hot air gun. This would have to be done skilfully by Floors Hull, so the profile would not become distorted.The OutcomeSteve McDonald from Floors Hull fitted the flooring in Albion Mills, along with the TopClip transition profiles. The end result looks fantastic, with the QTC42R and QVB1 curving well. As Steve says: “A very small amount of heat was used to create this tight radius, but the product itself was very flexible and went round with ease. Fantastic transition profile.”TopClip tops have 3 “teeth”, which allow them to be pushed flush to both floorcoverings which they transition between. This ensures that TopClip fits snugly on both the carpet and vinyl in Albion Mills, minimising the risk of trips. The tops are also slip resistant and durable, for extra safety.The flint coloured QTC42R tops look great with the dark and light grey carpet tiles. They fit perfectly with the aesthetic of the refurbished offices. Floors Hull, with the help of Quantum Flooring, have ensured that Albion Mills has a modern, professional design scheme for prospective tenants.

The ProjectRobinsons is one of the largest independent breweries in the UK. It has a rich history, with the family brewing in the centre of Stockport since 1849. Its main building is called the Unicorn Brewery, after the pub which the family originally ran from 1838.The bottling plant needed a refurbishment, to help keep employees safe. The brewery requested a highly slip resistant flooring surface, to deal with the inherent risk of liquid spillages in the plant, which could cause hazards. To go with the floorcovering they also needed a hard-wearing, robust, and highly slip resistant stair nosing.The stair nosing would need to have low slip potential in both dry and wet conditions, to help ensure safety in the plant. The main way the Health and Safety Executive (HSE) assesses the slip resistance of flooring and stair nosings is by using a pendulum test, which measures the friction of a surface. In this way, a pendulum test value (PTV) can be given to different products. Any stair nosing must have a PTV of 36, or more, in dry and wet conditions to be considered low slip potential.The ApproachSteven Holland Flooring contacted Quantum Flooring to discuss the most appropriate stair nosings for the project. They decided to go with Quantum’s Ecoglo slip resistant yellow tread material, Eglo-34, fitted into double-channel SF225R Slenderline carriers.Ecoglo tread infills are often utilised for their photoluminescent qualities. From just 30 minutes of charge with either natural or artificial light, Ecoglo’s photoluminescent strips can provide 7 hours of glow in either internal or external environments. Ecoglo also has a slip resistant silicon carbide tread material.Eglo-34 is one of the highly slip resistant silicon carbide tread infills in the Ecoglo range. It has a PTV of 70 in dry conditions, and 66 in wet conditions. These both easily exceed the minimum required guidelines for low slip potential in HSE publications, and slip resistance in BS 8300-2:2018. This made Eglo-34 ideal for Robinsons Brewery.The OutcomeSteven Holland Flooring expertly cut Quantum’s yellow Eglo-34 silicon carbide strips to size, and fitted them in both channels of the SF225R aluminium stair nosings. As Ecoglo tread material is secret fix, there was no need for plugs to hide the screws.The result looks fantastic and helps to ensure the safety of all employees at the Robinsons bottling plant. The stair nosing is durable and has very low slip potential, with the double channel Eglo-34 double treads maximising the surface area of grip. The SF225R profiles have a ramped back, to remove any trip hazard at the back of the steps.With the help of Quantum’s stair nosings, Steven Holland Flooring have ensured a safe, secure and visually pleasing staircase in Robinsons bottling plant. The installation will be used for years to come, helping to prevent slips, trips and falls on the spiral stairs.

Challenge The Hexagon is a well established multi purpose venue, in the heart of Reading that was built in 1977. As well as drama productions, it hosts a range of events such as Dance, Comedy, Classical Music, Rock and Pop concerts. The venue can hold up to 1600 people, with much of the capacity arranged in levels of banked arena-style seating with stepped access. The nature of the performances at the venue mean access up and down these stairways by patrons is often in low light levels which means there is a risk of slips and falls.

Southampton Airport is an international airport serving over 40 destinations. As the 18th busiest UK airport, it handled over 1.7 million passengers in 2013. Safety and security are paramount at any airport and emergency procedures and facilities need to be flawless and well maintained. Improvements were required to the emergency staircases in the airport’s multi-story car park. Previously, only a yellow strip was painted on the edge of the concrete steps across the 5 stairways, which meant the potential slip hazard was great.

The ProjectLoughborough College provides a range of courses in further education, along with apprenticeships and professional qualifications. It is based on one of the largest student campuses in Europe, sharing the area with Loughborough University. Over 2000 students attend the college, with some living in adjacent halls of residence.The college staircases needed to be refurbished. The flooring was previously terrazzo, and this was to be changed to a rubber flooring. This was suitable in terms of durability and slip resistance for the large amount of people on the campus. To complement the flooring, the stair nosings had to be equally hard-wearing and safe.The stair nosings needed to adhere to all Building Regulations guidelines, along with BS8300:2-2018 and the Equality Act. This meant that they needed to have great slip resistant properties, and stand out from the black flooring to create a ladder effect on the staircases. This would help people to navigate the stairways, especially those with visual impairments.There was a special request from the college which would help to attain this noticeable difference between the stair nosings and the steps: “Hot Rod Pink” tread material, to match Loughborough College colours.The ApproachMidlands Flooring was hired as the flooring contractor for the refurb. As Hot Rod Pink is not a standard stair nosing colour, Dave Wilson from Midlands Flooring got in touch with a number of manufacturers to see if anyone could rise to the challenge.Within 24 hours, Quantum Flooring returned its proposal for manufacturing bespoke Hot Rod Pink tread material specifically for Loughborough College. The unique stair nosing tread would be made from the same material as Quantum’s normal tread, meaning it would be slip resistant and suitable for the frequent foot traffic.Quantum’s SR125R stair nosings were chosen to fit the tread material into. These profiles have a ramped back, to ensure that there would be no trip hazard on the staircases. They are raked back on the riser, to ensure a perfect fit on the steps. Plus, Quantum’s UTA aluminium stair edging trims were fitted, providing a safe and aesthetically pleasing finish to the side of the steps on the open string stairs.The OutcomeQuantum ensured a fast turnaround on the stair nosings, using the QSMS free measuring service. A Quantum representative electronically measured all of the steps to their precise lengths, and sent the results to the distributor Carpet & Flooring in Birmingham for the stair nosings to be cut and drilled.Midlands Flooring fixed the stair nosings with Q-Fix contact adhesive, ensuring a strong bond to the steps. Secret-fix was used to drill the profiles, meaning the tread material could be fitted on site, and there was no need for unsightly plugs to hide the screws in the tread. Quantum’s SR125R stair nosings with Hot Rod Pink tread material look fantastic in Loughborough College. The college was delighted with the results.Loughborough College has a unique, on-brand stair nosing tread for its refurbished stairways. Midlands Flooring did a fantastic job on the project, and Quantum backed them up with innovation and expedience.

A Manchester based passive fire protection specialist has utilised products from the range of FIREFLY – including the versatile Phoenix Smoke & Flame barriers – to achieve the compartmentation of concealed spaces within the new Macclesfield manufacturing facility of a world-leading pharmaceutical giant.Firetech UK Ltd. is a key sub-contractor to DES for the construction of the extensive new laboratories and production plant for AstraZeneca, part of the FTSE 100 company’s continuing investment at its East Cheshire site for the distribution of drugs to markets around the world. Firetech was established more than 25 years ago and makes extensive use of FIREFLY  flexible fire barriers for its work on both commercial and domestic contracts. In the case of the Macclesfield project, Firetech purchased the FIREFLY  products via national distributor, Encon.  The Contracts Manager for Firetech UK on the Macclesfield Project, Josh Dodds comments: “We work nationwide though predominantly in the North-West of the country and have been using FIREFLY  products for the past five years, including here on this very large new plant.  Early on in the contract we installed a large quantity of Titan Lite™ 120:60 fire barriers in the ‘Amenities Area’ of the building and then when we were tasked with installing a series of smoke and flame barriers in the ceiling voids over the laboratories, we proposed the Phoenix product as being the most cost-effective solution. The work consumed approximately 540 square metres of the Phoenix to create a series of vertical barriers valued at some £50K.  Although we were able to employ standard details for the installation of the Phoenix barriers  and the Collaroll which wraps some of the beams and other features, FIREFLY has been involved from the earliest stages, providing general guidance and carrying out inspections.  The project has gone very well.”FIREFLY Phoenix is a lightweight smoke and flame barrier which facilitates compartmentation within buildings to provide up to 120 minutes’ integrity under BS476 Parts 20 & 22.  Certified by IFCC, the flexible and straightforward to install material is suitable for both new-build and retrofit situations.  Manufactured from woven and non-woven glass, the FIREFLY range is designed to optimise resistance to flame and smoke as well as offer heat protection in a wide range of scenarios. The flexible barriers are easy to install horizontally or vertically using a full selection of ancillary products.  Used mainly in the construction industry across the UK and Europe, FIREFLY fire barriers help to contain fire, giving building occupants extra time to evacuate and the fire service to enter safely.Images shown are taken during installation and some sections of the installation might be incomplete.

“How good is Knauf Insulation’s specification and technical support? Let’s put it this way, I’ve used Rocksilk® RainScreen Slab for every façade project since.”- Nikesh Patel, Façade Design Manager at A2O Cladding The Weald of Kent Grammar Annexe extension is a new three-storey satellite facility for Tunbridge Wells Grammar School for Boys in Sevenoaks. It comprises state-of-the-art classrooms for a cohort of 90 boys. A2O Cladding were appointed by Willmott Dixon to deliver the technical design and installation of the façade, which is finished with a white and grey silicon render set against a red Corium brickslip façade. One of their first tasks was to finalise the insulation specification based on three key requirements: thermal performance, non-combustibility and sustainability. Meeting the thermal performance challenge The first factor, the thermal performance of the rainscreen façade system, initially proved more difficult than expected. Nikesh Patel, Façade Design Manager at A2O Cladding explained: “U-values provided by the architect for a rainscreen façade system are a bit belt and braces because they’re based on assumptions. So, once we’ve confirmed the sub-structure, we redo them to ensure they’re an accurate representation of the building’s thermal performance.”   “The problem is the manufacturer we were working with couldn’t deliver the U-value of 0.18 W/m2K because they didn’t have the right software.” For most applications, the simplified methodology used for calculating U-values is sufficient. But it is not recommended for rainscreen façade systems, because it does not take into account the complex interaction between the Steel Frame System (SFS) and the insulation. Instead, a blanket correction factor is applied, which can lead to the over-specification of insulation – as it had in this case. To prevent this, 3D U-value calculations should be used. They thermally model the build-up based on the complex interaction between the insulation and the rails and brackets. This ensures greater accuracy giving the specifier a true picture of how the build-up will perform after construction, so it matches its design. But most manufacturers don’t have the capability to undertake these complex calculations in-house, so outsource the service to a third party at a cost to the contractor. Before they went down this route, A2O Cladding asked project architect Bond Bryan for advice, who suggested they contact Knauf Insulation.  “We’d not used Knauf Insulation before so didn’t know the standard of their technical support. The biggest tick in the box was they do free 3D U-value calculations – it really helped to keep the project on track.”  Using these calculations, the Knauf Insulation Technical Support Team recommended Rocksilk® RainScreen Slab for the façade insulation. The product has a thermal conductivity of 0.034 W/mK and crucially, a depth of just 150mm would meet the required U-value.  They also recommended 150mm of Rocksilk® EWI Slab with a thermal conductivity of 0.036 W/mK to insulate the rendered external walls. A2O Cladding also decided to use Knauf Insulation’s OmniFit® Slab 35 to insulate the junctions at roof level to ensure continuity of insulation. Fire safety at every height All three products have the best possible Euroclass A1 reaction to fire classification, so will not contribute to the development or spread of fire, should it occur. This meant they met the second specification factor, non-combustibility.  “The Annexe extension is under 18m tall but that would never influence our choice of insulation material. The A2O ethos is that we don’t touch combustible stuff when there are suitable non-combustible solutions available. I mean why would you introduce that risk? Using Mineral Wool insulation gives us, and the school peace of mind.”  Patel goes on to explain that Willmott Dixon has a reputation for quality and will only authorise the use of tested and certified systems. “As the façade contractor, it’s our job to ensure the quality of the supply chain. The fact that Rocksilk® RainScreen Slab is BBA certified for use in high rise buildings and for so many different build-ups meant it met the rigorous standards demanded for the project.” A focus on sustainability But choosing suppliers isn’t just about performance and fire safety. The third factor in the specification process was sustainability.  “As we finalise the technical design, we need to provide Willmott Dixon with a Technical Submittal for every product, and this includes details of its green credentials. It was another example of how Knauf Insulation makes things simple for contractors. They have EPDs for every product and all the relevant ISO standards, so our insulation specification sailed through.” As well as producing products that improve the thermal efficiency of buildings, Knauf Insulation has been taking steps to reduce the carbon footprint of its products. One example of this is its unique bio-based binder, ECOSE® Technology, which contains no added formaldehyde or phenol. ECOSE® Technology is made from natural raw materials that are rapidly renewable and is 70% less energy-intensive to manufacture than traditional binders, so it is more environmentally friendly. From technical support to performance and sustainability, Knauf Insulation scored top marks in all categories – which meant that A2O Cladding didn’t need to compromise on any of their specification requirements or criteria. 

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.

As a consequence of the Grenfell tragedy, an assessment of the building envelope was carried out on the 275nr residential apartment block in the centre of Leeds. It was found to be non-compliant with current regulations and in urgent need of replacement.The VariAL-SF system was selected as it complied with an A2 fire rating, with EN13501-1 classification by third parties, and satisfied the detailed planning constraints.The importance of the cladding refurbishment and replacement on this high-rise residential building cannot be understated. The building was identified by West Yorkshire Fire & Rescue Service late in 2019 as being high risk from the perspective of residents safety, due to the fact it was clad in flammable panels and onus was placed on the building owner to take swift action to make the building safe. As such, an ambitious 52 week programme for complete removal of the existing cladding and replacement was set out and achieved by the project team, despite significant limitations in terms of access and logistical challenges.To the passer-by, there is barely any discernible difference in the aesthetic of the building’s new facade, the colour-matching of the panels is incredibly accurate and allowed for a seamless transition to a much safer environment for the building’s residents.The apartment block was in the middle of a built up residential area. The contractor needed to obtain road closures from Leeds city council for two main roads which ran the full length and one side elevation.Furthermore the other main elevation was a pedestrian walkway with access to the apartment block , a hotel and several commercial buildings therefore safe access routes and segregation had to be installed and coordinated with the various parties involved.In addition, the building had to be reclad using 125ft cherry pickers working off the main road and pedestrian walkways therefore protective tracking systems had to be laid over the tarmac and paving to protect the existing materials.Throughout the building refurbishment, which took exactly 52 weeks, access to all the various buildings was maintained and contractor site personnel worked closely with adjacent building owners and especially the management team of the apartment block which accommodated 270 apartments to ensure minimal disruption.
