Abstract: Durability against fungal degradation and termite attack and fire resistance remain the biggest concerns with using cross-laminated timber (CLT) products in multistory buildings. Although mass timber products are inherently fire resistant due to their size, improving their fire performance in a way that further delays the spread of fire is always desirable. Additionally, in certain climates, such as the southern part of the United States, where wood products are exposed to hot and humid weather, a condition that is favorable for fungal growth and termite attack, CLT products should be properly protected. Borate is an environmentally friendly preservative that can be used to improve the fire performance of CLT products while also protecting them from deterioration by decay fungi and termite attack. This study is focused on investigating how borate treatment will affect the adhesive bonding properties and fire, decay, and termite resistance of cross-laminated timbers.
