Breathable Membrane for use in floors and walls
Vapour permeable membrane roll for use with Thermafleece insulation.
Thermafleece Breather Membrane is a light weight vapour permeable underlay designed for use in floors and walls or on top of insulation as a protective layer to prevent contamination of Thermafleece by dust and debris in Floors.
The material meets EN 13859-1 for pitched roofing and EN 13859-2 for walls. Thermafleece Breather Membrane has good water resistance, high breathability and is lightweight and easy to handle. The membrane is coloured light-grey on one side and white on the other with no text or images on either side, except a 150mm overlap line.
Thermafleece Breather Membrane comprises 3 layers; two outer layers composed of a non-woven polypropylene and an inner breathable microporous film
