Permo Sec Metal Underlay

25m x 1.5m roll (sometimes referred to as hairy chest) is used below standing seam zinc roofing, it should be laid across the roof from verge to verge, starting at the eaves and working up towards the ridge.

Permo Sec Metal fulfills a number of important purposes.

Permo Sec Metal helps prevent condensation beads on the rear of the zinc panels. Any beads which form on the rear of the zinc will come into contact with the strands of woven polypropylene mesh and are transported away to the membrane.

It also helps to create an air flow along the rear side of the zinc, carrying away any moisture below the surface of the zinc.

Should any water happen to get below the zinc the membrane acts as a secondary protection layer.

Permo Sec Metal will achieve up to 8db of sound resistance and help towards reducing any rain drumming sound entering the building.
