Product description
Breatheshield breathable roofing membrane, 120gsm – 1.5m x 50m. A vapour-permeable roofing underlay that keeps rain out and lets moisture escape the roof space.
A breathable underlay does two jobs at once: it sheds any water that gets past the tiles, and it lets water vapour out of the loft so timber and insulation can dry instead of trapping condensation. 120gsm is the standard premium weight, in a wide 1.5m roll for fewer laps across the roof. 50m per roll.
- Weight: 120gsm
- Roll size: 1.5m x 50m
- Type: vapour-permeable (breathable) underlay
Lay it across the rafters from the eaves up, lapping each course over the one below so water runs down and out. Tension it lightly so it doesn't sag between rafters. For a heavier, stronger sheet, step up to the 150gsm. Fix with our galvanised clout nails or staples.
