Product Q&A

Q:What is the difference between breathable and non-breathable roofing felt?

Non-breathable felt acts as a complete barrier and requires ventilation below to prevent condensation. Breathable membranes contain a microporous film that allows moisture vapour to escape while still repelling water.

Q:Do I still need ventilation when using a breathable membrane?

Breathable membranes greatly reduce condensation risk, but most roofs still require some ventilation at the eaves and ridge to meet building regulations and manage residual moisture.

Q:How long will a breathable membrane last?

When properly installed and protected by the roof covering, breathable membranes can last for several decades. Their lifespan may be reduced by prolonged UV exposure, incorrect fixing or mechanical damage, so always follow the manufacturer's instructions.

Q:Which way up do I lay a breathable membrane?

Most membranes have a printed or darker side that should face upwards during installation. This side offers better UV resistance. However, since most are vapour-open on both sides, performance is not significantly affected if installed the other way up.

Q:What are the available thickness and weight options?

The thickness ranges from 0.3mm to 0.6mm, and the weight options are 70g to 220g.
