Find out moreSamac's premium 140gsm Rooftec Breathable Membrane offers exceptional durability against extreme temperatures and is subject to laboratory quality control to ensure dependability. Featuring an airtight and vapour-permeable design, it promotes excellent air circulation to prevent moisture build-up within the roofing structure.
Versatile enough to work in warm and cold roofing applications, this membrane is suitable for use in Scottish sarking boards, timber-framed, or metal-framed constructions. Ideal for use in well-sealed ceilings with a roof ridge height not exceeding 15 metres, it is also compatible with on-site altitudes not exceeding 100m above sea level and can be used in areas without significant site topography.
This Rooftec Breathable Membrane provides outstanding UV stability for three months and is straightforward and hassle-free to install. Simply place it directly over the insulating material on the rafters and stretch it horizontally over the entire roof surface. Ensure a minimum overlap of 20cm at the ridge and a 15cm overlap along the red guideline. For pitches under 22°, overlap by at least 20cm.
Seam, overlap, butt joint or membrane damage can be masked with Samac's membrane adhesive tape. When connecting to other substrates, such as masonry, use silicon or self-adhesive butyl tapes.
