Technical Information Page 1 of 2 Udi TOP/ Udi TOP Premium Sark Boards Product A very robust, wood-fibre sark board for rear-ventilated roofs and exterior wall constructions. It is waterproof but at the same time highly vapour-diffusion permeable. A professional alternative to standard sarking and breather membranes. UdiTOP/ UdiTOP Premium sark boards are used for the exterior cladding of rear-ventilated roofs and exterior wall constructions providing a vapour permeable, thermal insulating layer In compliance with the German Roofing Industry Association’s guidelines, UdiTOP/ UdiTOP Premium sark boards are declared suitable for roof slopes of up to 20° and provide an interlocking layer in 22, 35, 52, 60, 80 and 100 mm insulation thicknesses. Softwood fibres with a homogenous and water impermeable impregnation. Pressure resistant with a perceptible improvement in the level of cold-, heat- and sound proofing. Tested for water resistance over a weathering period of 12 weeks. Please take note of snow loading in winter! The optimisation of the thermal protection properties through the tongue and groove connection on all edges. UdiTOP Premium provides even better U-values through its sandwich-layer construction. Officially technically approved, CE-certified and subject to third-party supervision. Suitable for applications on insulated and non-insulated roof and wall constructions in accordance with DIN V 410810: DAA, DAD, DI, DZ, DEO, and WAB, WH, WZ. (German standards).

Technical Information Page 2 of 2 Udi TOP/ Udi TOP Premium Sark Boards Installation Roof sarking boards: UdiTOP Boards are installed starting at the eaves with the tongue of the board facing upwards to the roof ridge. The boards are then laid offset to one another in a tight interlocking manner. The cut-off from the end of the first row may be used to start the second row as long as this provides a sufficient offset overlap to the next rafter. The rest of the boards are then installed as previously described. Any protrusions or edge joints should be treated using UdiSTEAM Primer LF and...
