Building Membranes

Building membranes help manage moisture and air movement within roofs, walls and floors. The right product depends on the construction and whether you need breathability, vapour control, airtightness or waterproofing.

Options include Tyvek HouseWrap to protect wall structures from external moisture while allowing water vapour to escape, Novia Black+ Essential for a lightweight, economical breather membrane, and Novia 500G Air and Vapour Control Layer to restrict moisture vapour entering the structure from indoors and help reduce air leakage when correctly sealed.

Browse our range below and compare building membranes by application, vapour resistance, water resistance, fire classification and roll size to find a suitable product for your project.
