Three is the magic number for modern housing development
An innovative combination of three reflective, insulating and low emissivity construction membranes from Glidevale Protect has been used to deliver the magic formula for a new build apartment scheme in Plymouth, Devon, achieving good energy efficiency and a low overall U-value for the wall construction. Scheduled for completion in September 2020, the development named Victoria Views @ Arundel Crescent delivers a new modern living space of 24 apartments.
Timber PAK (SW) Ltd, a specialist timber frame manufacturer was appointed by Harrington Homes (SW) Ltd to construct closed wall panels at their offsite factory, followed by delivery and installation on-site. The approved wall make-up incorporated Protect TF InterFoil, a vapour permeable, reflective membrane installed back to back with Protect VC Foil Ultra, an internal air and vapour control layer on the warm side of insulation. Both were faced into still airspaces, ensuring low emissivity performance and preventing heat loss. Supported by Protect TF200 Thermo, an external, reflective breather membrane, this three-membrane solution met the client’s target U-value of 0.19W/m2K, resulting in no increase on overall wall footprint. This helped Timber PAK to reduce insulation material costs and ensure no impact on labour cost.
Ron Luker, Director at Timber PAK (SW) Ltd commented “The innovative idea to use TF InterFoil within a cavity designed into the closed panel delivered our target U-value and saved money on insulation material. This is now one of our standard wall types for clients and I would recommend this product combination for the more onerous new build specifications.”
