1.5m wide roof tile underlayment/3-layer breathable membrane
High vapour permeable,
Light weight, easy to install,
Anti-skipping for pitched roof,
UV resistance for 3 months
3-layer waterproof roof membrane/roof tiles underlayment
Material: A three layer highly breathable, fully waterproof
membrane, constructed from high tensile spun-bonded nonwoven layers, around a microporous
polypropylene film. The outer layer forms the functional waterproof surface; the middle layer is
the breathable waterproof membrane and the inner layer protects the membrane from abrasion
and damage, also giving additional strength. This enables the fabric to allow
moisture vapor to pass through, whilst remaining fully waterproof. We can provide various colors on
upper surface, printed with the trade name and head lap lines.
Use: Breathable roofing underlay positioned immediately above the
insulation layer in a warm pitched roof, or in a cold pitched roof (ventilated or
unventilated). Breathable roofing underlay for use under tiles and sheeted roofs, over open rafters or on to
fully boarded substrates.
Breather membrane for timber frame wall construction.
