Klober's Permo extreme RS SK2 allows tiles and slates to be laid below recommended pitch
On building extensions, existing windows or pipework may preclude the normal minimum pitch for a tile or slate, however, Klober Permo underlay enables profiled tiles to be laid as low as 12.5°, flat tiles and slates 15° and plain tiles 22.5°. Permo extreme RS SK2 can be laid counter-battened on 12mm ply board or OSB sarking board, providing scope to use clay or concrete plain tiles and match the primary roof covering. Permo extreme acts as a weatherproofing layer in its own right and, with features such as high UV and tear resistance (shear tested to > 300N), the product can provide a means of temporary waterproofing for up to eight weeks. A monolithic, thermoplastic polyurethane (TPU) coating and double self-adhesive strips also provide a permanent seal at laps. Klober's Permo underlay has a capillary stop to prevent formation of condensation and a robust PES fleece to provide high mechanical load capacity.
