WISA-Duo

WISA Plywood

    * required

    WISA-Duo is a mixed construction plywood for various end uses. The panel is a combination of birch and spruce veneers. Birch veneers make the panel strong while spruce veneers keep it light in weight. The birch face veneers give the panel an attractive and even surface which is suitable for e.g. painting.

    WISA-Duo is suitable for construction usage. This meets the necessary EN standard and it is also CE marked.

    Bonding

    Phenolic resin cross-bonded weather resistant gluing according to EN 314-2/class 3 Exterior.

    Surface

    Panels have clean sanded wooden surfaces.

    Available surface qualities are S (II), BB (III) and WG (IV) according to EN 635-2, as well as WGE (improved WG) quality.

    WG and WGE are for end uses where the technical properties of birch is needed, S and BB for end uses where a solid surface appearance is also required.
