BC Wood Specialties Group – Thermally Modified Pacific HemFir
Pacific HemFir is widely valued for its high strength to weight ratio, its clear straight grain, and warm honey-colored appearance. It is used extensively in construction, joinery, millwork, windows and doors, as well as for preservative treatment and industrial applications. Due to its relatively low stability and natural durability, untreated Pacific hemlock is generally not used in exterior applications where it may subject to biodegradation. However, thermal modification can be used to improve selected properties for Pacific HemFir. Key benefits include increased greater dimensional stability, lower water absorption, lower equilibrium moisture content, and increased durability. These changes may make it suitable for use in exterior above ground applications such as siding, decking and fencing.
Thermal modification describes several processes that are used to improve wood properties by exposure to elevated temperatures in low oxygen environments. Processes include open and closed systems, using steam or other media to reduce oxygen content, and various time/temperature profiles.
