Glidevale Protect TF Interfoil
Application

Designed specifically for use within a timber frame wall panel to enhance its thermal performance.

Description

Protect TF InterFoil is an innovative, highly reflective insulating breather construction membrane, designed specifically for use within a timber frame wall panel to enhance its thermal performance. When installed facing into an unventilated airspace within the studs, Protect TF InterFoil effectively blocks infra-red radiation and increases the thermal performance of the airspace, and hence the overall U-value of the wall when compared to fully insulated construction.


Features and benefits:

  • Allows use of 0.032/ 0.035 lambda fibrous insulation to reduce cost and improve the acoustic performance of the wall.
  • Enables 0.03/0.032 lambda EPS alternatives to be used within timber frame construction.
  • Low emissivity reflective surface enhances the thermal performance of the wall.
  • Meets the permeability requirements recommended by TRADA and NHBC to prevent interstitial condensation.
  • Helps meet regulatory requirements.
  • Corrosion and damage resistant reflective surface.
  • UV and heat stabilised for long term durability.
  • Unaffected by conditions found within timber frame walls.
