Abstract
A laminated veneer lumber product utilizes low density veneers and is able to provide an edge stiffness value or MOE of at least 2,000,000 psi. This is the same strength as attained with high density veneers. The product has adjacent surface layers formed of low density incised veneer sheets having a moisture content of at least about 6% or adjacent surface layers formed of low density incised veneer sheets impregnated with phenolic resin and dried to a moisture content not exceeding about 5%. The surface layers are positioned on both sides of adjacent core layers which are either formed of high density veneer sheets or are formed of low density incised veneer sheets impregnated with a phenolic resin and dried to a moisture content not exceeding about 5%. The surface layers of low density incised veneer sheets having a moisture content of at least about 6% are densified against the core layers by at least about 5%.
