Thermafleece Breather Membrane

This is a light-weight 100 gsm breather membrane ideal for installing on top of loft insulation as a protective layer or under joints to hold insulation in position from below.

This membrane can also be used as a conventional breather membrane over the rafter or on the cold side of a timber frame where a heavier weight membrane is not necessary.  Thermafleece Breather Membrane is installed with the white side facing inside and the grey to the outside.
