EXTERNAL ENVELOPE 59


Airtight protection for Scotland self-build


A. Proctor Group has been chosen to provide enhanced thermal performance and protection for a sea-facing SIPS construction selfbuild property on the west coast of Scotland. Wraptite is installed as an external air barrier and alternative to a traditional standard breather membrane. Wraptite is the only self-adhering vapour-permeable air barrier certifi ed by the BBA and combines the essential properties of vapour permeability and airtightness in one self-adhering membrane. The self-adhered nature of Wraptite and its high level of water resistance and simplifi ed detailing made it an ideal choice. Alongside the Wraptite membrane, the thermal and airtightness performance of Wraptherm is included in the build. Wraptherm is a high-performance membrane composite that is self- adhesive and consists of a 10 mm Spacetherm aerogel insulation blanket bonded to the face of Wraptite. The fi nal part of the airtightness and vapour barrier system is provided by Refl ectatherm Plus, a refl ective,


high-resistance vapour barrier 01250 872 261 proctorgroup.com for internal


walls, ceilings and fl oors that will signifi cantly reduce the risks of condensation by providing the highest levels of moisture resistance.
