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 for use on the "cold" side of the installation.
- For a breather membrane designed for use in the "warm" side of an installation, see the Thermofloc Variable SD Membrane.

Application
Thermafleece Breather Membrane is ideal for supporting insulation between suspended floor joists or as a protective layer above insulation installed between floor joists, preventing the accumulation of debris on top of the 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, run it across, staple to the lower side of the next joist, run it over the top of the joist, and repeat. Ensure an overlap of at least 100mm between layers of membrane.
Thermafleece breather membrane can also be laid over loft insulation to keep it clean and free of debris.
The membrane should be installed with the grey side away from the insulation.
