ProctorPassive Corners – vapour permeable factory formed window corners.
ProctorPassive Corners are factory formed from a robust 3-ply polypropylene textile to protect the building fabric and insulation from moisture ingress during construction and for the life of the building. Unlike non vapour permeable products such as foils, tapes, bitumen based membranes and other sealants, ProctorWrap Corners are highly vapour permeable to let your building breathe.
ProctorPassive Corners are made using a unique welding process in the UK to a patented design for ease of installation. In addition to keeping out wind driven rain and drafts, the material permits vapour to escape without reaching dew point thus preventing condensation and related problems such as mould, timber rot, corrosion and loss of thermal resistance of the insulation.
