Technical Specifications: Brand: A. Proctor Group Product Type: Breather Membrane Range: Wraptite Permeability: Airtight & Vapour Permeable Roll Size: 50m (Length) x 1.5m (Width) Depth/Thickness: 0.6mm Why Choose Proctor Wraptite? The Proctor Wraptite membrane is a market-leading external air barrier that simplifies installation while providing excellent airtightness and vapour permeability. It enhances thermal efficiency by minimising energy loss, making it an essential component for modern sustainable construction. Proctor Wraptite FAQs What makes Proctor Wraptite different from other air barrier membranes?Proctor Wraptite is a fully bonded exterior air barrier membrane that provides excellent airtightness and vapor permeability. Unlike other membranes, it does not require mechanical fixings, thereby minimising the risk of thermal bridging and allowing simpler installation. How does Wraptite promote energy efficiency in buildings?By minimising unwanted air leakage, Wraptite assists in maintaining a more consistent indoor temperature and thereby reduces the need for heating and cooling. This leads to less energy consumption, enhanced comfort, and better building performance overall. Is it possible to use Wraptite in new constructions and refurbishments?Yes. Wraptite is ideal for new-build and retrofit projects alike. It is especially suited to recladding projects, as it enables the provision of an external airtight layer without interfering with the internal structure. Is this membrane suitable for high-rise buildings?Yes. Wraptite has been tested and rated according to BS EN 13501-1 standards with a fire rating of B-s1,d0. This makes the classification suitable for application in high-rise buildings where fire performance is a critical factor. Do I need additional tapes to close Wraptite overlaps?No. Unlike most conventional membranes, Wraptite is fully self-adhered, so overlaps automatically create an air-tight seal. Nevertheless, Wraptite Tape is provided for detailing at complicated junctions, penetrations, and repair. Is it possible to apply Wraptite on all substrate types?Indeed, Wraptite adheres well to a wide range of surfaces, including timber, concrete, steel, sheathing boards, and rigid insulation. It has a high level of adhesion that creates an air-seal with no primers or secondary fixings required. Is Wraptite a vapour control layer (VCL)?Wraptite is a vapour-permeable, airtight breather membrane that provides the means of letting moisture out while enabling airtightness. Unlike conventional internally positioned Vapour Control Layers (VCLs), Wraptite is positioned on the exterior to facilitate detailing and eliminate potential risks of condensation. Does Wraptite provide weather protection during construction?Yes. Proctor Wraptite acts as a temporary weatherproofing layer upon installation, shielding the building from wind-driven rain and moisture until the final cladding or external finish is established. Is Wraptite suitable for airtightness in Passivhaus construction?In fact, Wraptite has been successfully used in numerous Passivhaus-certified projects. Its high airtightness, when combined with vapour permeability, makes it an ideal solution for achieving exceptionally low air leakage rates. How does Wraptite behave around fixings and penetrations?Wraptite has undergone testing to demonstrate low air leakage, even when penetrated by fasteners. Its self-adhesive quality minimizes the likelihood of air movement occurring behind the membrane. As an extra precaution, Wraptite Liquid Flashing or an EPDM washer may be applied around fasteners. Can Wraptite be used on extensions and smaller structures?Indeed, although most commonly applied in high-performance commercial buildings, Wraptite also proves extremely valuable for residential projects, including extensions. Even if the primary building is not airtight, applying Wraptite to an extension will still enhance overall energy performance. What is the expected lifespan of Wraptite after being installed?Proctor Wraptite is engineered to deliver long-term performance and durability. It retains airtightness and weather resistance throughout the lifespan of the building when correctly installed and protected with external cladding.
