Slate for Bituminous Membranes

Natural slate granules are used as the self-protection layer of bituminous membranes: applied to the upper face of the membrane, they protect it from UV rays, increase its resistance to weathering and extend its service life.

The product is a black lamellar slate, washed and dried, with a specific weight of 1,25 kg/l.

It is available in the 0,6/1 mm, 0,6/2 mm and 0,6/2,5 mm sizes. For coloured membranes, coloured slate is also available.
