Product data
Field of application
- for vented pitched roofs
- minimum roof pitch 1,5°
- for installation directly on the thermal insulation / wood sheathing
- for roof pitches from 1.5° (seam welding)
- for roof pitches from 5° (SK DUO)
Is a vapour permeable roof underlay for installation directly on the thermal insulation or the wood sheathing. The underlay can be welded on the joints. The roof underlay is suitable for roofs with increased need for rain-tightness (because of small roof pitch for example). According to German classification it is UDB-A . The membrane guarantees extreme resistance against wind-driven rain while humidity in form of vapour still can pass the construction. Increased raintightness proved by Holzforschung Austria. (Report no. : 1158/2014-BB). Type: Standard = without adhesive tape, SK DUO = double sided adhesive tape.
