DuPont Tyvek Supro Breather Membrane Underlay 1.5m x 50m

DuPont Tyvek Supro Breather Membrane is a superior vapour-permeable underlay, able to provide air tightness and moisture protection in both commercial and residential buildings, especially designed to be used in various roof applications including cold, warm or hybrid and metal low pitched roofs, sarking board systems and floors and walls. It presents a highly cost effective solution due to the fact that it does not require ridge tile or soffit ventilation, nor additional airspace. It can be installed vertically and horizontally, laid directly on top of insulation material, laid under counter-banners or over the roof rafters. It provides a maintenance-free and durable solution, since it can withstand normal roof conditions unless overexposed to sunlight. In order of maintaining the roof water-tightness, it is important that all potential damages to the products are repaired prior to adding the tiles or slates.
