Underlays

The protective coat for your roof

Underlays protect against water penetration and provide a back-up to the roof cover as a complement to the roof structure. The Braas Monier range includes permeable, impermeable and reflective underlays depending upon the performance requirement and application. They help to keep the wind out, prevent heat and cold loss and save energy. The different types of membranes are constantly enhanced to meet increasingly stringent quality and technical requirements. Braas Monier tests them in its own wind tunnel and laboratory and they are also evaluated externally. All are CE-marked and comply with national standards.
