Daltex FrameTX® Thermo

DALTEX® FrameTX® Thermo is a multi layer breather membrane that enhances the thermal performance, reducing the U-value (thermal transmittance)

Daltex® FrameTX® Thermo is a high performance breather membrane specifically designed to enhance the thermal performance of timber & steel frame structures. Daltex® FrameTX® Thermo reduces the U-value (thermal transmittance) of walls by insulating the cavity between the frame and outer cladding, thereby inhibiting radiant heat transfer across the cavity. Daltex® FrameTX® Thermo is particularly effective as the breathability of the membrane is not compromised by its thermal properties, thereby minimising the risk of condensation in the structure.
