ProctorPassive Wraptite UV-SA

Vapour Permeable Self-Adhering Airtight UV Resistant Membrane

Vapour Permeable Self-Adhering Airtight UV Resistant Membrane

ProctorPassive Wraptite UV-SA combines all the best properties of a UV resistant vapour permeable water and air barrier membrane in one innovative self-adhering product designed for use behind open jointed cladding. Wraptite UV-SA utilises a patented full coverage vapour permeable adhesive to provide high vapour permeability.


ProctorPassive UV-SA is suitable for installation in vertical wall constructions behind ventilated facades with regularly spaced open joints no greater than 30mm wide accounting for no more than 30% of total facade surface area. The rainscreen facade has to be ventilated according to the facade manufacturers installation instructions and with a min. 20mm ventilation gap.

Long term UV resistance is dependent on the percentage of the cladding that is open, the size of the openings, and the width of the cavity.
