Glidevale Protect Barriair VCL
Application

Suitable for timber frame, pre-cast concrete and traditional brick and block construction. Can be used on walls and ceilings to significantly reduce air leakage in any construction.

Description

Protect BarriAir with integrated lap and sealing tapes is a high performance and multi-purpose coated non-woven membrane which forms a highly effective air leakage barrier with vapour control qualities.


Features and benefits:

  • Suitable for timber frame, pre-cast concrete and traditional brick and block construction.
  • 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.
  • 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.
  • Separate Protect sealing tapes also available.
  • Ideal for Passivhaus projects.
  • Easy to cut and lightweight to handle in 1.5 x 50 m rolls.
  • 3 m wide option, without integrated tape, ideal for factory fitting.
