Traditional, highly-modified SBS roofing felt, used for single-layer insulation of wooden sloping roofs. Mechanically fastened with roofing staples or roofing nails.

Application

The product is used for waterproofing on steep roofs, on wooden substrates made of boards or OSB boards as an independent single-layer insulation and as a base layer under discontinuous roof coverings such as weave roof, weave metal sheets, bituminous shingle, etc. It can be used as a top layer in coverings multi-layer, consisting of traditional roofing felt, including for single-layer renovation of such roofs. Roofing felt as insulation for discontinuous roofing with a minimum slope of 14 (25%), for independent insulation, it is intended for roofs with a minimum slope of 20 (36.4%).
