Collection: Airtight & Windtight Membranes

Airtightness and Widtightness are important aspects to consider when building or renovating. Air leakage into and out of a property can be detrimental to the thermal performance of insulation. Creating an airtight seal in the property with an airtight & windtight membrane can prevent cold air from entering and hot air from escaping. 

We also have a range of airtight tapes and accessories to go along with the airtightness membranes.
