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.
Thermafleece Breather Membrane comprises 3 layers; two outer layers composed of a non-woven polypropylene and an inner breathable microporous film. It is designed to be used on the "cold" side of the installation. For a breather membrane designed for use in the "warm" side of an installation see the Variable SD Membrane. If in any doubt about which breather membrane you need for your project, please contact us.
Thermafleece Breather Membrane is ideal for supporting insulation between suspended floor joists or as a protective layer above insulation installed between floor joists to prevent the accumulation of debris on top of insulation. The membrane can be nailed or stapled to the underside of the floor joist if access permits. Alternatively the membrane can be installed from above the rafter.
For best performance staple the membrane to the lower side of the joist and run the membrane across before stapling to the lower side of the next joist before running over the top of the joist and repeating. Ensure an overlap of at least 100mm between layers of membrane.
Thermafleece breather membrane can also be laid on top of loft insulation to keep the insulation clean and free of debris.
