Vapour Permeable Breather Membrane

Here at Insulation Superstore we have a range of vapour permeable breather membranes for your latest project from reputable brands such as Cromar, Tyvek and Easy-Trim.

What is a vapour permeable membrane?

Vapour permeable breather membranes allow water vapour to pass through the membrane, out of the roofing system or walls. This helps to reduce the amount of condensation build-up within the roof or wall and insulation, which can lead to long term problems such as mould and damp which can lead to serious structural issues. 

Vapour permeable membranes are installed on the outer edge of the insulation board or roofing board. They can also be fixed to wall structures. When installing vapour permeable membranes it is important to use  strong tapes to affix each layer of membrane, specifically on the joints to prevent any air leakage. 

Why install a vapour permeable breather membrane?

An average house produces 14 litres of moisture a day, and also experiences high levels of air leakage, which contributes to heat loss. Installing a vapour permeable breather membrane will allow the moisture to leave the building, whilst preventing air leakage, and therefore reducing heat loss. Additionally, installing vapour permeable membranes can also reduce the risk of rotting timber battens, joists and roofing systems, as the moisture levels are much lower.
