Celotex Insulation used on Somerset conservation houses

17 Oct 11 For the traditionally designed Alvington Place housing development located in the Conservation Area of Alvington near Yeovil, Somerset, insulation was needed that could be relied upon to deliver superb thermal efficiency at the right price.

Having used Celotex’ renowned insulation boards in the past, developers Strongvox opted to use it again on the cavity walls of the scheme.

With a strong track record as a turnkey developer in the West Country, Strongvox design, build and sell their properties with a large emphasis on local architecture, traditional materials and fitting in with the surrounding vernacular. Its Alvington Place development proved no exception consisting of a variety of 40 two, three and four bedroom quality homes, planned in line with regional design and constructed from established materials fitting in perfectly with the beautiful local area.

Strongvox selected 50mm Celotex CW4000 for the cavity walls of the homes at Alvington Place. With 60% of the UK’s carbon footprint a direct result of the built environment, providing high performance insulation is crucial to the nation’s move to sustainability and provides savings for homeowners in the face of rising energy costs. The use of high performance insulation was also pivotal to Strongvox’s commitment to building the most thermally efficient homes.

The thermal properties of Celotex CW4000 have made it a consistently popular choice with architects and specifiers. Made from PIR (polyisocyanurate) with foil facers for improved emissivity, it offers an impressive lambda value of 0.022 W/mK as well as BBA (British Board of Agrement) certification and an ‘A+’ rating when compared to the BRE Green Guide 2008.

The boards also hold uniform thermal performance across the product for supremely reliable performance. In addition to excellent thermal performance, Celotex CW4000 has low Global Warming Potential and zero Ozone Depletion Potential.

With a good strength to weight ratio, Celotex CW4000 insulation boards are easily handled and can be cut and shaped onsite with hand tools. Strongvox’s operatives placed the boards between cavities and held them in place with clip-ties to create a high performance thermal envelope. As the boards do not trap moisture – unlike fibre and mineral wools – they provide long lasting and reliable performance and are especially suitable for cavity walling, where high levels of moisture can affect the integrity of masonry.

As well as cavity walling, Celotex offers products that can be used in a variety of other applications, including pitched and flat roofs, timber and steel frames and in under-screed flooring.

With approximately 50% of the Alvington Place development complete and families already enjoying their new build homes, the scheme provides well built houses in an attractive rural environment. Benefitting from good value and high performance insulation, the families can boast reduced heating bills and carbon footprints for years into the future.
