As part of Soundis’ ongoing work supplying high-quality acoustic flooring at various Premier Inn’s around the UK, we were brought on to provide acoustic flooring to their Penrith site, one of Premier Inn’s many new sites across the UK.Due to it’s service and close proximity to the Lake District, this hotel has become extremely popular in just a short period of time.Just like a number of our other Premier Inn projects, we supplied an acoustic flooring system to the 1st and 2nd floors. This superb system provides excellent levels of soundproofing while being used in a shallow floor build up.We also supplied XPS Insulation on the ground floor with a 22mm T&G chipboard overlay, maximising durability for the increased footfall.The system we supplied reduced the overall noise within the hotel, allowing Premier Inn to fulfill it’s promise of a good night’s sleep. This installation carried out by UK Acoustic Systems proved to be a great success, reducing the noise levels within the building and helped ensure the most comfortable stay possible for guests.

Up to 186 floors of the world’s tallest building were levelled with ARDEX products – the largest volume of levelling and smoothing compound used on one project in the company’s history.

A 40,000m2 flooring refurbishment of Heathrow Airport’s Terminal 1 helps 12 million passengers a year to experience a faster and more comfortable journey, from check-in to take off.

The synergy of ARDEX products was the only solution to protect the original Grade II listed tiles from the installation of 24 tonnes of moisture-sensitive granite slabs on the new floor.

Lululemon specified ARDEX polished Concrete Topping (PCT) as it gave them the complete freedom to accomplish almost any design they desired whilst still offering a durable retail floor system.

National Flooring Co Ltd, one of our Approved Contractors was approached by Moy Construction Co Ltd who were awarded a contract to refurbish the swimming pool and changing areas at Perseid School in Surrey. The school offers an educational provision for children with learning difficulties and/or physical/sensory difficulties, and therefore, safety was paramount. As part of the refurbishment a hardwearing, slip-resistant flooring system that offered excellent longevity was essential. The floor had been previously tiled, but due to water ingress, kept failing and required frequent repair. Rising maintenance costs and risk of slips prompted the school to look for alternative solutions and resin became an obvious choice. A Degafloor resin floor provides a seamless, hardwearing, and impermeable finish that will offer years of service. Moy Construction Co Ltd removed the existing floor tiles and installed a new screed prior to the installation of the resin system. From the offset, achieving a floor finish with a suitable slip rating was non-negotiable.The Degafloor QTA system is a quartz trowelled system which can be laid to falls. The system, which is broadcast with a quartz aggregate, provides excellent slip resistance, even in wet conditions, ensuring high levels of safety are always maintained. The project, which included the swimming pool surround and adjoining changing rooms, totalled 145 sqm of floor and 135 lm of cove. The installation was completed over 5 days and to the satisfaction of Moy Construction Co Ltd, who were happy to have the project completed to a high standard, on time and within budget.

The British Museum opened its doors in 1759. Now home to some 8 million works from a number of different cultures, the museum stands as an iconic London attraction. The Museum made the decision in November 2013 to replace the restaurant’s old flooring, as it could no longer handle the vast number of visitors. W B Simpson Ltd, was the chosen tiling contractor to complete the new installation. Marc Poland, Director at W B Simpson Ltd said “The architect consulting on this project specified we use ARDEX UK’s products.

1,400m² of PanDOMO® Floor, and 700m² PanDOMO® Wall provided the luxurious seamless finish required by Delugan Meissl Architects. At its opening in 2012, the orchestra pit was the largest of its kind globally and is reputed to provide some of the best acoustics in Europe.

In densely populated urban areas of the cities, where the number of floors in housing is sometimes limited and private gardens are rare, a rooftop terrace or patio is becoming a popular design choice. However, many residential buildings with rooftop gardens don’t see much daylight and careful consideration is required to determine an access point to the roof terrace. For such rooftop projects, a new dimension of roof access is offered by the LAMILUX Flat Roof Access Hatch Comfort range, designed to give a generous daylight intake in attic apartments alongside convenient access to the roof terrace creating an air of grace and beauty both internally and externally. The LAMILUX Flat Roof Access Hatch Comfort range now introduces its fourth product into the family, giving more choice and flexibility when creating a luxurious living space with an exclusive ambience. Featuring unrestricted use as a natural ventilation device and convenient access to the roof terrace, the indoor climate also benefits from the high energy efficiency of the range thanks to the thermally broken frame and excellent air tightness values.The existing Solo and Duo Flat Roof Access Hatch products from LAMILUX open laterally by moving one or two panels horizontally to create direct access to step onto the roof terrace, whilst the space-saving hinged opening Swing variant swiftly opens its one meter by 3000 or 3500 mm long aperture to 84 degrees in just 25 seconds. The fourth, and newest addition to the Access Hatch Comfort repertoire the Square, makes it possible, for the first time, to also use spiral and platform staircases underneath. Until now, access to the roof was limited to straight stairways due to the elongated rectangular shape of the roof access hatch range. The Square only takes 45 seconds for the concealed hydraulic drives to silently open the 4m² glass element of the skylight by 70 degrees. As with the Swing, the new variant does not require any additional space on the roof terrace than its own size in closed form, even when open, thanks to its swing mechanism.   Visually, the aluminium border frame throughout the product family, attracts attention as an architectural highlight. The aluminum profiles and the reveal surface can be coated in all RAL colours offering further choice and exclusivity. Since the glass panes and frame feature a flush edge detail both internally and externally, and all variants are designed with an inclined surface, the range boasts not only a visually appealing seamless design, but also ensures that rainwater can run-off easily without leaving any dirty edges or water ponding. Safety is standard in the Flat Roof Access Hatch Comfort product family with fall-resistant glazing which can be walked on to a limited extent for cleaning purposes. As an additional safety feature, a light barrier is installed as standard which prevents the closing of the access hatch as soon as it detects something in the entrance area. In terms of energy, the new roof access hatch continues the tradition of all LAMILUX skylights: The overall system, which is free of thermal bridges and isothermally balanced and the option of special glazing meets modern demands for sustainability, energy efficiency and climate protection which ultimately save heating costs and minimizes condensation. All four products in this family have one further thing in common: They are delivered completely pre-assembled to the construction site, lifted onto the roof by a crane provided by the customer and then installed swiftly and easily. This minimizes the risk of errors and saves valuable time – both for the contractor and for the apartment user who ultimately gains access to the roof terrace.

A Degafloor Approved Installer - The National Flooring Company Ltd were approached by a A 4-star hotel, in the South of England, who had decided to update their flooring system around the swimming pool. The existing floor tiles, which had started to debond posed a trip hazard and therefore needed to be replaced. The client also advised they were experiencing problems with standing water.Following the removal of the existing floor tiles, the installation of a new screed was required to build back the levels and ensure there were adequate falls in the floor for water to run back into the pool. Throughout the installation, the gym remained open, and it had been advised that the pool closure needed to be kept to an absolute minimum. The National Flooring Company installed the Degafloor Deep Fill Mortar Repair system, a fast-curing underlayment, which ensured the refurbishment programme could continue with no downtime due to curing.The existing drain was removed and replaced, along with the light box and leveller covers, which all received new stainless-steel units. A new trim was fixed around the perimeter of the pool and the Degafloor resin system, which has an excellent bond to metal surfaces, was abutted up to all the stainless-steel items. The Degafloor QTA system used within the project, is a quartz trowelled system that can be laid to falls. The system is broadcast with aggregate to provide an extremely slip resistant finish, even under wet conditions, making it ideally suited to a swimming pool surround. Coved skirting was installed around the perimeter of the room creating a completely impervious finish, with no weak spots and therefore reducing future maintenance costs. The full refurbishment was completed over 12 days, ensuring that the closure was kept to a bare minimum.The clients main requirements were they required an anti-slip floor that would eliminate the current situation they had with standing water. They specifically requested that the closure was kept to a minimum as they are a "member's club" as well as facilitating the hotel, which remained open throughout the installation. The client was extremely satisfied with the end result and felt they now have a floor finish that is much better suited to their environment.

The existing waterproofing had failed due to a previous poor installation, the result of which saturated the insulation below the exterior roofing. New high performance solutions were specified that included a range of IKO roofing waterproofing systems to protect both the flat and pitched roofing areas of the building. IKOslate, a robust and durable tile was specified for the pitched roof due to vandalism and the fragility of the current system, whereas a tapered scheme was required for the flat roofing - IKO Ultra Prevent alongside a cold applied liquid solution (IKO Polimar) for the more intricate details.

This resulted in:Quicker install & less use water than a wet screed systemImproved acoustic performanceImproved fire performanceImproved thermal efficiency resulting in reduced energy costs for the end userHigher loading performance, creating a solid substrate for the finish to be applied directly toReduction in overall embodied carbon & installation of a product that offers a high recycled contentLifetime guarantee of the buildingClick the link below to read the full case studyhttps://www.instacoustic.co.uk/case-study/kings-cross-london-n1c/

Find out why we recommend rafter ventilation slides when using spray foam insulation in pitched roofs where a high-resistance roof membrane is in place. The rafter slide not only provides ease of access to the external roof for future repairs/replacement, when ventilated appropriately, it can be effective at managing moisture.

Lewis Deck was chosen, on this particular project in London, for a number of the key benefits the system brings. These being the strength of the system with only needing a thin concrete screed on top, the acoustic qualities & vibration control properties and the speed an ease of installation. This project even requested much longer sheets than standard in an effort to speed up the installation process. In fact you can see from the main photo above that some of the sheets were extremely long. The longest being just over 6.5m.This project was the installation of a new suspended, loadbearing concrete floor above an existing floor below. The space being used as a plant room for the hospital. The Lewis Deck was installed over a suspended steel grid of Light Gauge Steel C-section joists. A thin concrete was then installed over the top.This was a quick installation with the Lewis Deck being installed and then used as a safe working deck ahead of the screed being pumped in.

The $10-billion dollar development required a rooftop waterproofing and flooring system that could withstand the islands continual exposure to heat, moisture and sunlight. ARDEX provided the perfect system to cope with such an extreme environment.

This extensive 9,000m2 new build project, covering 4 key operating theatres, two treatment rooms, assessment units, a discharge ward and an admission department benefitted from a full ARDEX flooring system.

refurbishment project posed particular challenges in respect of the flat roof, which consisted of a solid concrete deck, followed by screed laid to falls, a thin dense concrete layer and three bituminous membrane layers. The new roof specification required the application of new insulation to upgrade the thermal performance and a new single ply waterproofing membrane. Due to the location of this project and the presence of existing bonded layers, adhesive application was ruled out at an early stage and a mechanically fastened solution was sought.Initial pull-out tests confirmed that fixing was required through the existing screed and direct into the concrete deck. With the roof’s high exposure rating and dimensions, wind load calculations indicated that only corner and perimeter zones should be used, which demanded a high density of fasteners in these areas.the solutions provided by SFS included its TIA adjustable fastener in combination with the isoweld® 3000 heat induction welding system. This fastener system included specially coated isoweld® stress plates combined with 230mm and 300mm FI-R-20 sleeves and the 150mm long TIA fastener. These were installed through the insulation and screed layers and were mechanically fastened into the concrete substrate.The fasteners were applied through the insulation boards in a field fix grid pattern followed by the Protan SE single ply waterproofing membrane, which was then installed using the specialist isoweld® 3000 system, welding the membrane directly onto the isoweld® stress plates. This provided an extremely secure fix, without having to duplicate fasteners, and the associated drilling, and without the need to penetrate the waterproof membrane as would be necessary on seam fix systems.

This project involved the construction of a Data Centre just outside Dublin, with a focus on incorporating a green roof. MOY collaborated with the client, their design team, the main contractor, and the roofing installer to execute the roof installation for an extensive green roof. The green roof utilized MOY's Paraflex FM Global approved Warm Roof System, featuring Paratherm T 120mm insulation board and an anti-root cap sheet. The final touch included the installation of a sedum blanket grown in Ireland, containing native Irish sedum species registered in the national biodiversity database, creating a durable and vibrant living roof.

The client desired a green roof at the back of this beautiful family home. Access was very restricted. The speed and ease of transporting and installing our modular trays meant minimum disruption for the homeowner. Trays were delivered to site on pallets and handballed to the roof. The modules were laid down onto a geotextile fabric. Pebbles were then laid around the perimeter between the trays and any outlets to provide the required firebreak. Vegetation blended quickly creating a seamless green roof and, looking out from the upper floors, a sense of continuity from the house across the garden.

The Protec System was used to waterproof the domed green roof areas of this striking, sustainable house development which was featured on Chanel 4’s Grand Designs. With an ambitious vision and a tight budget, Robert and Milla Gaukroger set about transforming a dated 1980’s house overlooking Lake Windermere into a state-of-the-art, eco-conscious home. Since the house lay in beautiful hillside surroundings, in order to blend into this setting, the domed roofs of the house were to be covered with a wildflower meadow mix to provide a green roof construction.The SolutionThe Protec System was chosen as a waterproofing membrane for the roofs as it is ideally suited for green roof applications. Lightweight, flexible and highly durable, the system can easily accommodate structural expansion movements and is tough enough to resist root penetration. The Protec system was applied to over 350m2 of domed roof to provide a long-lasting waterproofing membrane.The key reasons why Eastleigh chose Protec are the same reasons that has seen it become one of the fastest growing cold-applied liquid roofing systems in both the new build and refurbishment markets. Combined with the timber cladding to the verticals of the building, the finished aesthetics of the development blended seamlessly with the surrounding areas.A warm roof build-up that can be made waterproof at multiple stages:For larger projects the Protec system can be made temporarily waterproof at two stages prior to the application of the full waterproofing system. The first stage is upon installation of the sealed, aluminium-faced vapour barrier.The second phase follows the reinforcing of the foil-faced insulation board joints with Protec resin and taping mat. This enables a much more controlled approach to the installation with a greatly reduced chance of rain causing disruption and damage during the works.Highly flexible membrane:Regardless of the size of the roof, Protec forms a homegenous membrane, without a single joint or seam and without the need for any expansion joints.RapidCure technology for quick installation:The application of Protec as a liquid, through to the curing process where a solid, tough membrane that can be walked over, takes only 30 – 60 minutes. This enables large sections of the roof to be fully completed in a short space of time.Installing the Roofing SystemsThe Protec System provided waterproofing to all flat roof areas as well as the extensive parapet wall sections. The roof areas were made up of two designs: the Protec Warm Roof System (approx 7,500m2) and Protec applied to concrete as part of an inverted roof design (approx 1,000m2).The roof installation was carried out with a planned, phased approach that was synchronised to the wider construction schedule. For the warm roof areas, the first stage was to fill the troughs of the structural metal roof deck with acoustic insulation infills that will dampen external noise within the leisure centre. Next, the crowns of the deck were primed ready to receive the self-adhesive vapour barrier.The use of a high-performance aluminium vapour barrier not only eliminates the risk of condensation within the roof, but also provides temporary waterproofing protection, which is extremely useful on larger works such as this.The Polyroof RES Insulation boards, which comprised of a two layer system totalling 170mm to achieve a U-Value of 0.14 W/m2K, were bonded using high-performance PU adhesive to the vapour barrier. Following the wind uplift calculations it was determined that mechanical fixings were not required for this application – making for an extremely rapid installation. As you can probably imagine, fixing through 170mm of insulation into the crowns of the metal deck can be a tricky and time-consuming task.A key advantage of using a tongue and groove insulation system is that the finished surface of the roof is smooth and level without any unsightly board steps that can also lead to standing water issues. The insulation board joints were sealed using Protec resin with Polymat Taping Mat 450 which, in addition to providing additional strength to the joints, also creates a temporarily waterproof layer.For the inverted roof sections, Protec was applied directly to the primed concrete/screed surface. The membrane was inspected by Polyroof Technical Services, signed off and then covered with inverted roof components. An interesting fact when using Protec in inverted roof situations is its incredible durability performance – as tested by the BBA, Protec “can provide an effective barrier to the transmission of liquid water and water vapour for the design life of the roof in which it is incorporated”.Monitoring and CompletionThroughout the duration of the contract, Polyroof Technical Services carried out regular site visits that were reported back to Interserve as part of Polyroof’s free-of-charge contract monitoring service. This enabled the client to keep up-to-date with the progress of the roof installation in detail and also provided peace of mind that the original specification was being closely followed and implemented.Polyroof worked closely with the Roofline Group during the installation, enabling the challenges were identified and solved in an efficient and coordinated manner – saving the client time and money.
