Proctor Wraptite is a high-performance, self-adhesive vapour permeable air tightness membrane that revolutionises modern construction. This unique breather membrane provides a simple yet effective way to achieve a consistent airtight external seal, dramatically improving the building's thermal performance and energy efficiency. It combines the critical properties of airtightness and vapour permeability into one robust, easy-to-use product. This outstanding external breather membrane is made with Triple layer polypropylene micro-porous film laminate, with a proprietary acrylic moisture vapour permeable adhesive and siliconecoated PET release liner Key Features & Benefits Exceptional Airtightness: The primary function of the Wraptite membrane is to deliver outstanding airtightness. By creating a continuous seal, it significantly reduces air leakage and prevents unwanted lateral air movement through the building envelope, leading to substantial reduced heating and cooling costs. Highly Vapour Permeable: While being completely airtight, Proctor Wraptite is also highly vapour permeable. This allows trapped moisture vapour from within the structure (e.g., from timber framing) to escape efficiently. This feature is crucial for preventing condensation and protecting the structural integrity of the building. Effortless Self-Adhesive Application: Wraptite is a self-adhesive airtightness membrane, which ensures remarkable ease of installation. Its patented adhesive backing provides a secure bond to most substrates without the need for specialist sealants or tapes at the overlaps. This creates a solution that is yet airtight – but also self-adhered, saving significant time and material costs on site. No primer required. Also, it can left exposed for up to 120 days during construction Durable & High-Performance: As a leading airtight breathable membrane, Wraptite is engineered for durability, providing a robust, long-lasting solution for the building envelope. Applications Proctor Wraptite® is suitable for a diverse range of applications in both commercial and residential construction like: SIPs panels Steel and timber framed constructions Façade systems Cassette Floor construction Unventilated warm roofs Exterior Gypsum Sheathing Aluminium (painted or mill finish) OSB Rigid insulation Cast-in-place concrete Rigid vinyl Pre-painted steel Galvanized metal Precast concrete Steel Concrete block Plywood
