Rosboro Custom GlulamCustom Treated Glulam

Rosboro utilizes local treaters to recommend the preservative option that best fits the intended use and provide a quality treated product. Rosboro recommends oil-borne or mineral spirit based preservatives for glulam since water-borne preservatives such as ACQ and ACZA cause excessive checking and splitting in glulam. Custom Douglas fir glulam can be ordered with specified treatment to protect against decay, mold, and insect attack. Preservative treatments are selected to meet requirements of commercial, industrial, or residential applications.
