Airtight Membranes

Our range of airtight membranes for vapour control and airtightness. Membranes are used to ensure the airtightness of a building by preventing draught and heat loss.

They also help reduce structural damage from occurring over time by preventing damp and mould growth in the building fabric. Overlapping membranes need to be sealed together using airtight tape in order to create one continuous airtight layer. These are the products that will keep your building dry and airtight, ranging from basic vapour control layers and breather membranes to more intelligent variable membranes.

The necessary level of airtightness does not have to be harder to establish, but it is essential to choose the best solution to ensure the fabric’s performance.

We offer a range of airtight membranes which enable airtightness and vapour control in roof and wall connections, with products from Gerband and our own Passive House Systems range.
