Glidevale Protect TF200 Thermo Breather Membrane

Application

Low emissivity insulating breather membrane developed to enhance the thermal performance of external 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. Designed for use on the external wall, on the cold side of the insulation.


Features and benefits:

  • Aligned with STA Advice Note 18, with aged thermal resistance of 0.77 m²K/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.
  • Used within an unventilated cavity helps to create a radiant barrier to prevent heat loss and deliver a energy efficiency benefit on the wall's overall thermal performance.
  • Helps to meet the Building Regulations requirements in the UK and Ireland.
  • Corrosion and damage resistant reflective surface.
  • UV and heat stabilized.
  • 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.
