Summary
Large volumes of hardwoods are available in Eastern Canada with qualities that do not meet the requirements of appearance wood products. There is therefore a real potential for the use of these in structural products such as glulam and cross-laminated panels. However, it appears that the laminations of these species are different from the softwoods for which the adhesives have been developed. In order to support the development of structural products using hardwoods, bonding conditions (roughness, porosity, pH, etc.) but also standard delamination tests (ASTM D905-2008, ASTM D52662013) must be documented.
