SINTEF Technical Approval - TG 20457 Side 3 av 3 In general, it is recommended to cover the wind barrier with an external cladding as soon as possible. However, it is considered that the wind barrier system can remain uncovered, as indicated in clause 4 "Properties", provided that the building is not subjected to large amounts of driving rain. It is also a prerequisite that all joints are protected with tape and that all board edges (for instance along the bottom, sides and top of the wall, and around wall penetrations) are protected against rain. When the boards are used for wind bracing, as specified in section 4, all board edges shall be supported by studs of at least 45 mm width. Screws SINIAT WAB 41 screws with length of at least 42 mm must be used when fixing in wood. For steel studs, the screws must have a length of at least 32 mm. Sealing of joints SIGA Wigluv sealing tape, with a width of at least 50 mm, must be used. Horizontal joints must be sealed with two tape strips where the upper tape strip overlaps the lower tape strip with 25 mm before the vertical joints are sealed. The surface of the boards must be dust-free and dry before the tape is applied. The manufacturer's instructions must be followed. Transport and storage The boards shall be covered during transport and stored on a levelled support in dry conditions. 7.
