About Roofing Underlays
Securing your roof space is an important part of protecting the structure and energy efficiency of your whole build. Our range of roofing underlays, also known as roof underlayments, are purposefully designed to provide an essential secondary line of defence against water entry whilst absorbing any condensation that forms beneath your roof cladding. Fire retardant, airtight and vapour permeable, our advanced synthetic underlays ensure moisture can escape from your roof space in a stable protective layer that is both tear and shrink-resistant. Self-supporting and available in rolls of different sizes, they are easy to lay and can also be used to line walls and ceilings.
