Protect BarriAir Air Barrier & Vapour Control Layer

Protect BarriAir is a high performance and multi purpose coated nonwoven membrane which provides a highly effective air leakage barrier along with vapour control qualities. Protect BarriAir installed on the warm side of the structure immediately adjacent to the insulation can be used on walls and ceilings to significantly reduce air leakage in any construction helping to meet Building Regulations and Standards requirements for air tightness.

- Provides an airtight system when installed with sealed laps.
- Dramatically reduces heat loss through the building fabric.
- Improves the thermal performance of all insulants by reducing convection flows.
- Tough, durable with high tear resistance.
- Easy to cut and lightweight to handle in 1.5 x 50m rolls.
- Provides support to mineral wool and rock fibre when fixed to timber frame studs or rafters.
- Helps to avoid interstitial condensation risk within insulation in accordance with BS 5250.
