Thermafleece Breather Membrane is a lightweight and vapour-permeable underlay designed for use on floors, walls, or as a protective layer above insulation. Comprising three layers - two outer layers of non-woven polypropylene and an inner breathable microporous film - this membrane is specifically designed for use on the "cold" side of installations.

Key Features:

Construction:

• Comprises two outer layers of non-woven polypropylene and an inner breathable microporous film.

Versatility:

• Ideal for supporting insulation between suspended floor joists or as a protective layer above insulation installed between floor joists to prevent debris accumulation.

Installation:

• Membrane can be nailed or stapled to the underside of floor joists if access permits or installed from above the rafter.
• For optimal performance, staple the membrane to the lower side of the joist, run it across, staple it to the lower side of the next joist, then run it over the top and repeat.
• Ensure a minimum overlap of 100mm between layers.

Additional Applications:

• Suitable for laying on top of loft insulation to keep it clean and free of debris.

Dimensions:

• Width: 1.5m
• Roll Length: 16.7m (Area: 25m²)
• Roll Length: 50m (Area: 75m²)

Key Facts:

• Waterproofing membrane
• Highly vapour-permeable
• 3-layer laminate with a microporous core
• Good tensile and nail tear strength
• Grade F (Fire)
• 1 month UV resistant
• CE compliant
• Recyclable

Installation Note:

• Install the membrane with the grey side facing away from the insulation.

Thermafleece Breather Membrane provides an effective and versatile solution for maintaining a protective layer in various insulation applications. Its three-layer construction and vapour-permeable design make it an ideal choice for optimizing insulation performance.
