Abstract: A laminated wood product comprising providing a plank presenting a pair of parallel major surfaces, a pair of minor surfaces, a pair of end surfaces and a longitudinal direction parallel with said major and minor surfaces and perpendicular to the end surfaces, said plank having a water content of more than 25% by weight, preferably more than 30% by weight. At least one of the major surfaces is laminated to a surface of a second member.

Abstract: The present disclosure relates to a method of producing a laminated wood product, comprising providing a plank presenting a pair of parallel major surfaces, a pair of minor surfaces, a pair of end surfaces and a longitudinal direction parallel with said major and minor surfaces and perpendicular to the end surfaces, said plank having a water content of more than 25% by weight, preferably more than 30% by weight, initializing at least one longitudinal crack in the plank, drying said crack initialized plank to a moisture content of less than 20% by weight, and laminating said crack initialized plank by gluing at least one of its major surfaces to a surface of a second member, thus forming the laminated wood product. The disclosure also relates to a laminated wood product, which may be formed according to the method.
