Permo forte underlay – helping roofers stay safe

Among its market-leading vapour permeable roofing underlays, Klober Permo® forte is a heavy duty, 4-layer product with a built-in safety grid designed to help prevent falls through the roof. Its mesh reinforcement gives a degree of strength vastly superior to lightweight 2-layer membranes while Permo forte SK2 also has self-adhesive edge tapes which provide a lasting airtight seal of laps. As one of the highest performing and most widely specified underlays since such products were first introduced, Permo forte can be used on fully supported or unsupported tile, slate or metal roofs. In addition to having BBA and IRB certification it has also been independently tested by the BRE for wind uplift performance.
