Nine Elms Parkside: Under Screed Acoustic LayerWhen carrying out a large-scale housing development it pays to rely on tried and tested products to provide acoustic certainty. Regupol 7210C (REGUPOL sonus core 5) is one such product. With a long history of reliability, it is now being installed in the UK’s largest single-phase build to rent development.The ProjectNine Elms Parkside is the redevelopment of a 5.6 hectare Royal Mail depot site in Wandsworth, a key part the Vauxhall Battersea Opportunity Area, sitting between Battersea Power Station and Nine Elms market and adjacent to the new US Embassy. The scheme is master planned around the new Nine Elms Linear Park, part of a new green link connecting Battersea Park in the west, along the Thames to Lambeth Palace Gardens in the east.Blocks B and D Nine Elms Parkside were acquired in 2019 by real estate groups Henderson Park and Greystar who contracted Telford Homes to construct 641,000sft of residential space to a design by Allies & Morrison.The scheme consists of 894 build to rent apartments in two twin blocks of 10 to 17 storeys, each of which also features 12,500sft of amenity space with a rooftop swimming pool, gym, pet spa, children’s play space, private dining rooms, cinema rooms and a sky lounge. There are two large outdoor terraces, yoga gardens and community herb gardens complete with beehives. The scheme will also contain 25,000 sq ft of retail and community space.CMS Danskin is supplying Regupol 7210C (REGUPOL sonus core 5) Acoustic Resilient Layer to Stanmore, the leading drylining and façade specialist subcontractors who are carrying out the screeding between floors in the apartments.The project to supply commenced in 2020 and we have to date supplied over 96,000m2 of the product. Topping out took place in July 2021, residents will begin to occupy the scheme in 2022 and the units are expected to be fully complete in 2024.Acoustic insulation for new build apartmentsSince 2004 the Building Regulations require that separating floors between apartments meet specific requirements for airborne and impact sound transmission. The requirements are set out in Approved Document E, Resistance to the passage of sound.With a 150mm concrete slab, common in multi storey new build apartments under 18 storeys, a product is required to isolate the structure from a floating screed, thereby significantly reducing impact and airborne noise and enhancing the living conditions of occupants of the apartments.Regupol 7210C (REGUPOL sonus core 5) Acoustic Resilient Layer is an isolating layer specifically designed for this purpose and is the go-to product for floating screeds over 150mm concrete slabs.Regupol 7210C (REGUPOL sonus core 5) Acoustic Resilient Layer isA high performing insulation that delivers superior impact and airborne performance.An under-screed product designed to isolate screeds from the main structure simply and conveniently.Manufactured from recycled materials – typically aircraft tyres – making it cost effective and sustainable.Compatible with all types of floor screed, making it adaptable across a project and between projects.Aimed at constructions where Pre-Completion Testing (PCT) is preferred to a Robust Detail (RD) approach.Testing under screed insulation for acoustic performancePre-Completion Testing of acoustic floor installations gives a contractor more flexibility, allowing alternative layouts between apartments. If the designer wants to make changes to the layout of apartments, they won’t need to change the Robust Detail as each eventuality can be tested on site. With a project of over 860 flats a 10% required test rate would produce 86 acoustic tests, but the flexibility of using a PCT solution like 7210C (REGUPOL sonus core 5), and its reliability as an established product, makes that regime cost effective.Telford Homes, a long-standing customer of CMS Danskin, were looking for a Pre-Completion Testing product for Nine Elms blocks B and D. Regupol 7210C (REGUPOL sonus core 5) Acoustic Resilient Layer is an established product from an established brand, so not only were Telford Homes familiar with the product, but their experienced screeders Stanmore were also confident that testing on site would not raise any issues.Over a year into the project all the tests carried out so far have been successful.Supply chain reliabilityFor a large project with over 100,000m2 of product required over a long contract period, reliability of supply is essential. Any delay in supply can hold up wet trades and affect the critical path. With support from our supply chain partners, CMS Danskin has ensured over 96,000m2 of product has been delivered on time to date.Specify Regupol 7210C (REGUPOL sonus core 5) Acoustic Resilient LayerRegupol 7210C (REGUPOL sonus core 5) Acoustic Resilient Layer is a tried and tested solution to under screed insulation over a concrete slab, be it in apartments, hotels, education buildings or student accommodation.

Chelmsley Wood Shopping CentreBauderflex bituminous waterproofing systemSynopsisChelmsley Wood Shopping Centre, located in East Birmingham, was experiencing leaks with their current flat roof waterproofing system and so they needed a quick, high quality solution to remedy the situation. Although competitors had suggested the only option was to strip the roof, Bauder found a more cost-effective answer by using our in house Troxler Moisture Gauge to identify any areas of wet roof construction, removing the saturated areas and then overlaying the whole roof area.Bauder Building BoardProject:Chelmsley Wood Shopping Centre Location:BirminghamProject Type:RefurbishmentRoof Area:4500m²Specifier:Black Cat ConsultancyApproved Contractor:BBR Roofing LtdProject challengesThe works were to be undertaken in the middle of winter on the existing single ply covering which kept freezing when the operatives were drying the surface. Fixing down of the insulation boards (to the existing waterproof covering) was a noisy operation which also exposed the retail tenant below to risk of water ingress. Work had to be undertaken on a roof where ridges and valleys had to be navigated whilst managing the waterflow.The specification allowed for the removal and replacement of the saturated areas as identified by our moisture mapping survey. This operation had to be planned to ensure that the retail stores were not put at risk in terms of water ingress, but still managed to keep the works progressing to schedule. This was particularly difficult due to the exposed site and the inclement weather encountered. The resultAs a result, Large sections of cable bespoke design had to be developed with Bauder to overcome these challenging site details without the need to decant the retail tenants below. trays and handrails had to be lifted in situ so the roof works could be completed without compromising electrical or mechanical install.By working closely with the centre, a method of work was developed which fulfilled these criteria in terms of waterproofing, health and safety and business protection of the shopping centre. System installedBauderflex bituminous waterproofing system1 BauderFLEX K4EA torch applied SBS elastomeric bitumen capping sheet, featuring spunbond polyester reinforcement to allow the finished product to cope with structural movement without fracture.2 BauderTEC Sprint DUOA self-adhesive elastomeric bitumen underlayer with DUO lap technology.

Comprising of nine shops and several residential flats, properties 29-47 High Street Polegate required a full roof refurbishment after complaints of water ingress into the residential buildings. Proteus Waterproofing conducted a thorough survey which revealed that the existing roof build up, made up of a timber deck and 2-layer felt, had been previously repaired but was now at the end of its serviceable life.Being a residential building with a combustible deck, protecting individual properties from internal fire spread was a key consideration. Compartment walls were identified allowing Proteus Waterproofing to provide a solution that would meet regulatory guidance relating to the junction of compartment walls and roofs in Approved Document B whilst meeting the needs of the client.Proteus Waterproofing specified their robust reinforced bitumen membrane range of Proteus Pro-Felt®, including a bespoke hybrid insulation approach, where instead of a full replacement consisting of entirely non-combustible insulation, a scheme was designed to meet the requirements above and either side of the compartment walls, offering the client the most cost-effective solution possible that would also mitigate any unnecessary increase of weight loading elsewhere on the roof.High Performance WaterproofingThe waterproofing and existing deck were stripped back and re- decked with 18mm plywood. When removing the existing waterproofing, our approved contractor, carefully recorded the exact location of the party walls as no drawings of the upper story flats were available.Proteus Pro-Felt® SA AVCL was used as a vapour control layer to allow for the application of the hybrid combination of 150mm Proteus Pro-Therm PIR insulation and 150mm Proteus Pro-Therm Mineral Wool insulation. A thermal calculation was undertaken to ensure that the final result met the requirements of Part L of the National Building Regulations. These were both adhered with Proteus Pro-Bond Foaming Adhesive. Proteus Pro-Felt® SA Underlay Plain was laid and finished with Proteus Pro-Felt® Ultima Plus Fireguard Mineral Capsheet, providing the client with a fully waterproofed Part B and Part L compliant roof, guaranteed for 20 years.Proteus Waterproofing worked closely with the Proteus Approved Contractor, to ensure the project was delivered to a high standard.Health & SafetyWhen working on occupied buildings, safety is always of utmost importance, as well as keeping disruptions to a minimum.

Completed in 2016, The Woodsman’s Treehouse is a unique property set high up in the branches of a 200-year-old oak tree in Dorset. The fantastic property is six metres tall and sits 30 feet up in the trees.The Woodsman’s Treehouse needed high performing insulation for the walls in order to keep its guests warm year-round. Due to the already compact area he was building the treehouse in, Guy didn’t want to compromise on space when it came to the thickness of the walls. He needed space saving insulation that still maintained the performance levels of traditional insulation, in order to make sure the heat produced from the wood burner didn’t escape from the building.SuperFOIL provided the project with our SF60 multifoil insulation, which is the world’s highest performing multifoil. The insulation is just 100mm thick, so was the perfect solution to ensure space wasn’t compromised, whilst still offering high thermal performance. The insulation has a 3-in-1 design which consists of three layers- insulation, vapour control and radiant barrier. What this meant was that the treehouse would be protected from condensation whilst still maintaining the right temperature, whatever the season. Offering excellent value for money, SF60 is ideal for both new build or retrofit projects and is certified by BBA and LABC, ensuring it meets the needs of building regulations. The insulation is also made from 40% recycled materials and is fully recyclable at the end of its 50+ year lifespan, so contributed to the sustainability of the project.

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.

As part of an exciting regeneration project in Cardiff, Lowfield Timber Frames specified SMARTPLY AIRTIGHT panels alongside a supply of their timber kits for a development of 12 two-bedroom houses in Heath, Cardiff.As part of an exciting regeneration project in Cardiff, Lowfield Timber Frames specified SMARTPLY AIRTIGHT panels alongside a supply of their timber kits for a development of 12 two-bedroom houses in Heath, Cardiff.The homes are built to strict Passivhaus standards, offering improved health and wellbeing conditions for occupants whilst requiring very low levels of energy for space heating or cooling. Additionally, using timber frame for the construction lowers the carbon footprint of the development.The major benefit of a Passivhaus build is the reduced energy consumption during the operating life of the structure. This will ultimately lead to reduced energy costs, heating bills, and even lower carbon emissions for the planet.The average air test result for the 12 homes came in at below 0.5 ACH. A Larsen truss panel (a lightweight wall extension which creates extra wall space to a house insulation) was also used in the project. It was 330mm deep with the finished wall make-up being closer to 500mm.Darren Jarman, Managing Director of Lowfield Timber Frames, commented: “The Highfields scheme in Cardiff was just one of several passivhaus schemes we have completed over the past 2 years. We now have an external wall build-up that not only meets the passivhaus standards, but also has extremely low embodied carbon credentials.“The external wall has been fire tested and achieves the airtightness required, all in all, reducing the heating requirements and the running costs of the property.”SMARTPLY AIRTIGHT is an airtight OSB/3 panel with integrated vapour control and air barrier properties for use as structural sheathing in timber frame structures. The airtightness is engineered into the OSB panel substrate, whilst the factory applied specialist surface finish technology provides increased and constant vapour resistance on the warm side of construction. The panels are suitable for both new build and renovations.The distinctive green layer of SMARTPLY AIRTIGHT is a UV cured coating providing increased and constant vapour diffusion factor. In addition, it provides a smooth and durable surface for taping the connections.The panels made to OSB/3 grade, are moisture resistant and can be used in humid conditions (service class 2). The hygroscopic nature of the OSB panel acts as a humidity buffer to help prevent interstitial condensation within the timber frame structure in limited cases of reverse diffusion.Jarman concluded: “Whilst there are other products available which will achieve the airtightness, we feel SMARTPLY AIRTIGHT is the most robust solution available and eliminates the possibility of accidental damage, resulting in a failed test.”The ambitious project is part of the ‘Cardiff Living’ programme, a 10-year partnership between Cardiff Council and Wates Residential, which will deliver 1,500 new homes at sites across the city.Discover more about SMARTPLY AIRTIGHT and its applications here: https://mdfosb.com/en/products/smartply-airtightFind out more about Lowfield Timber Frames here: https://www.lowfieldtimberframes.co.uk/Twitter: @LTFltd
