What is a Breather Membrane?
In the same way that a gore-tex jacket protects a walker or a cyclist, a breathable membrane protects your building from wind, rain and condensation.
With the improvement of quality and the tightening of building regulations, modern properties are becoming ever more airtight. This is great for reducing cold drafts and your heating bills. However, a negative impact is that the steam created by cooking, showers and the very air you breathe, has no-where to escape but upwards into your roof.
