PROCTOR Wraptite UV Self-adhesive UV Vapour Permeable Airtight Membrane - 1.5 x 50m
Proctor Wraptite UV is a Class B fire-rated membrane that combines the best properties of vapour permeability and air tightness in one innovative, self-adhering product, which is specifically designed for use behind open jointed cladding.
Wraptite UV has exceptional water resistance and UV resistance to provide a “shadow” appearance within open rainscreen façades. Manufactured from polyester and a functional coating, with a proprietary acrylic moisture vapour permeable adhesive and silicone-coated PET release liner.
Wraptite UV bonds (no mechanical attachment) to multiple substrates for air tightness and ease of installation, negating the requirement for a primer, sealants or tapes. The product provides an initial grab with a full curing time of approximately 6 hours depending on environmental conditions.
Wraptite UV prevents lateral air movement enhancing the buildings thermal performance. With a rating of Sd 0.06m, it provides a high vapour permeability in a commercial quality, self-adhered, airtight breathable membrane.
To protect the membrane from mechanical damage, the joint openings in the façade covering have to be less than 40% of the area, and a maximum of 50mm wide.
Whilst for use behind open jointed cladding, the membrane is specifically designed for those who require protection against water ingress for extended periods of time, in a range of applications, including the storage and transportation of volumetric modules, offsite panelised systems and/or within high rise façade construction.
Wraptite UV would also provide a shadow gap detail behind window flashing details, or in open jointed façade systems in offsite construction, rainscreen and timber cladding systems.
