Barn Conversion Makes Efficient use of YBS SuperQuilt
A widespread shortage of rigid foam insulation boards has led a regional builder to successfully trialling YBS SuperQuilt multi-layer insulation for the conversion of a single storey stable structure into a spacious and energy efficient new dwelling.
Bray and Sons is a specialist in exclusive new build and refurbished residential projects, mainly around the Boston area of Lincolnshire and is currently close to completing the four bedroom property in the village of Wrangle. The Boston branch of Jackson Buildbase has supplied fourteen rolls of SuperQuilt for the conversion which Jason Bray and his team have used to line both the exterior walls and areas of the roof.
Jason explained: “When I bought this old stable block, which dates from 1865, the walls were in a fairly poor condition, but we have stabilised them and improved the thermal performance by constructing an inner face of Fibolite blocks to create a solid 9” construction. There is, though, a shortage of the rigid foam boards we would normally use to line barns and other ‘traditional’ builds, so we decided to try the YBS SuperQuilt.
In fact we think it is slightly quicker and easier to install, simply stapling it over the face of the vertical DPM membrane which is screwed to battens fixed vertically up the blockwork, finished with a layer of standard plasterboard and a skim coat. Then also we have used it within the kitchen and lounge where the ceiling is vaulted, fixing the SuperQuilt across the underside of the rafters, having pushed 100mm of Knauf OmniFit insulation up between them to leave a 25 mm air gap.”
Jason summed up the success of SuperQuilt for this retrofit application: “The surveyors overseeing this project and the issuing of the NHBC type guarantee are Butler & Young, who are happy with the build-up for both the walls and roof. Overall, with some 210 square metres of SuperQuilt used for the conversion of this four bed, two bathroom luxury property, I feel the product has been a great success and I would specify it again.”
Recognised by the NHBC, compliant with Part L of the Building Regulations, and holding an Agrement Certificate, SuperQuilt is suitable for both new-build and refurbishment work. It comprises 19 layers including reflective foil, expanded polyethylene and polyester wadding to provide a cost effective and user-friendly alternative to much thicker insulation materials. Installed with a 25mm cavity it controls not just radiated energy, but thermal conduction and convection, while also combating thermal overheating in the summer months.
