Insulation plays its part in creating energy-saving coastal property “Intelligent use” of multi-foil insulation takes the heat off garden rooms 058 JULY 2017 RCIMAG.COM Zink Copper Stainless 01992 801927 www.almhm.co.uk When it came to the design brief for the property, the owners Sue and Dick Russill, who are keen walkers wanted to make the most of the panoramic views of the Pembrokeshire Coast. Dick explained: “Our main design considerations were to maximise the enjoyment of the views, to make the house eco-friendly, not to go overboard with technical gadgetry, to be able to accommodate visitors in great comfort and to ensure a nonobtrusive visual impact given the beauty of the surrounding countryside and coastline.” The couple wanted the construction to be timber-frame with high levels of thermal insulation, and for the home to be able to make the most of passive solar gain. They also wanted to have plenty of glazing so that someone entering the house from the front door could come inside and immediately see straight through to the sea views out the back. Working with Scandia-Hus, a designer and supplier of Swedish energy-saving homes, Sue and Dick were able to come up with a design that matched all their requirements, as well as their budget. Bluestone Builders were also able to help the Russils achieve their dream home and increase the already high levels of insulation to ensure sustained thermal comfort. The wall insulation comprised 70mm of rigid insulation panels using Celotex GA4000, along with a multifoil blanket enveloping the exterior frame. The pitched roof insulation included 120mm Celotex XR4000 boards, as well as bubble insulation membrane and mineralwool cladding. Both Celotex GA4000 and Celotex XR4000 enabled the pitched roof and flooring throughout the property to achieve lower U-values, with the inclusion of low emissivity foil facings further enhancing thermal performance within cavity air spaces. Both certified under BBA certificate number 95/3197 and 16/5352, with low global warming potential (GWP) and zero ozone depletion potential (ODP). Celotex XR4000 and Celotex GA4000 were not only easy to install, but crucially were able to future-proof the energy performance of the Pembrokeshire property. Aside from insulation requirements, the exterior was covered in fibre-cement cladding in a grey colour that complemented the contemporary appearance of the building, whilst fitting in well with the surroundings. The Russills say their home surpasses their expectations, with its bright and airy rooms and panoramic views. Sue also commented that visitors: “Can’t believe how warm and comfortable it is, even without the heating on”. She says this is the result of the high levels of thermal insulation, as well as the large amount of glazing on the eastern-facing side of the house, which maximises solar gain. The cliff-top home is designed to make the most of the stunning vistas and Sue and Dick Russill can now enjoy the views from their energysaving, stunning property.

The company aims to enable property owners to make use of their outdoor rooms all year round and to achieve this a lightweight, timber-framed replacement roof structure using YBS SuperQuilt multi-layer insulation was developed. YBS says that the choice of its BBA accredited product ensures that the Insullite conservatory roof achieves Building Regulation approval, while maintaining a low profile appearance complementary to existing conservatories. Neil Birchall, managing director of Insullite, commented: “The Insullite solid tiled conservatory roof has been intelligently designed to solve all of the common problems that conservatory owners face; we do this by using a multilayered foil insulation system. Our solution features a SuperQuilt 19 layer multi–foil insulation, which has an excellent thermal value as it deflects the extreme hot and cold temperatures away from the occupied space. We also employ a sound deadening insulation, which unlike rigid materials, completely silences the weather. “This intelligent use of insulation technologies means that the Insullite tiled conservatory roof achieves a U-value of 0-18 W/m²K – meaning the insulation system is one of the best on the market. Conventional conservatories with glass or Perspex roofs are either freezing cold in winter or boiling hot in sunny summer weather, owners choosing our solution can enjoy their conservatory all year round.” Explaining why his company chose YBS as a key supplier, Birchall added: “We assessed all of the multi-foil products available on the market and found that YBS SuperQuilt best suited our system needs. This was partly because we needed one that was externally reflective to combat solar gain in hot weather and also it is fitter friendly, being cross-stitched and therefore rip resistant. “Thanks to the thermal performance that we can offer and our ability to produce an improved, tiled roof for any size of existing conservatory, we are seeing business growing steadily with turnover now in excess of £1 million a year.” Recognised by the NHBC and compliant with the current version of Approved Document L to the Building Regulations, SuperQuilt comprises of 19 layers including reflective foil, expanded polyethylene and polyester wadding, which they say provides a cost effective and user-friendly alternative to much thicker insulation materials. Installed with a 25mm cavity, the company says that it controls not just radiated energy, but thermal conduction and convection. It creates an effective vapour control layer and will also combat thermal overheating in the summer months. www.insullite.co.uk INSULATION
