Glidevale Protect TF200 Thermo Breather Membrane
Application

Developed to enhance the thermal performance of timber frame walls, Structural Insulated Panels (SIPs), Cross Laminated Timber (CLT) panels and steel frame construction.

Description

Protect TF200 Thermo is a robust, highly reflective, insulating breather membrane which has been developed to enhance the thermal performance of timber frame walls, Structural Insulated Panels (SIPs), Cross Laminated Timber (CLT) panels and steel frame construction, and offers Class 1 surface spread of flame to BS 476-7. It provides a significant thermal benefit along with strength and performance enhancements over other reflective breather membranes.


Features and benefits:

  • Aligned with STA Advice Note 18, with aged thermal resistance of 0.77m2K/W, incorporating printing and using typical 600mm stud centres.
  • Resists the passage of water, wind blown snow and dust into the interior of the building.
  • Low emissivity reflective surface enhances the thermal performance of the wall.
  • Helps to meet the requirements of Approved Document Part L and Scotland Part J.
  • Corrosion and damage resistant reflective surface.
  • UV and heat stabilised.
  • Good nail tear resistance compared with alternative membranes.
  • High burst strength, tough and durable.
  • Unaffected by conditions found in timber frame walls.
  • Meets the permeability requirements recommended by TRADA and NHBC.
  • BM TRADA independently certified for all applications.
