Proctor Wraptherm Airtight Membrane is an innovative, high-performance composite insulation and airtightness solution developed by Proctor Group for refurbishment and retrofit applications. This product combines a 10mm Spacetherm insulation blanket bonded to the face of Wraptite vapour permeable, airtight self-adhesive membrane, providing an innovative system that enhances both thermal efficiency and building airtightness.
Designed for use on the internal face of existing façades and wall constructions, Wraptherm helps reduce thermal bridging while creating a continuous airtight layer. This self-adhered membrane forms a durable seal against unwanted air leakage, helping to improve energy performance and occupant comfort.
Unlike traditional air barrier systems, Wraptherm remains vapour permeable, allowing moisture vapour to pass through the construction while maintaining an airtight envelope. Its vapour-open yet airtight design helps support healthy building fabric performance and moisture management.
Its ultra-thin profile makes Wraptherm ideal for projects where space is limited but thermal upgrades are required. By combining insulation and airtightness in a single product, Proctor Wraptherm provides an efficient solution for improving thermal performance and reducing heat loss in refurbishment projects.
