Purewood Structural Panels
Purewood Structural Panels (PSP’s) are an innovative solid wood construction system developed by Pacific Timberworks (patent pending). This method of construction aligns itself with our mission of using building materials that offer sound ecological and healthy-living benefits.
Purewood Structural Panels are made of untreated, locally grown wood from sustainably managed forests and are manufactured entirely without glue or other toxic ingredients. PSP’s extend their ecological benefit by making use of the ample supply of pine beetle wood or combination of wood species – fir, cedar, hemlock, that fit our criteria.
To produce the panels, tongue and groove connections are manufactured onto 2” x 6” and 2” x 8” dimensional lumber and dry-stacked on top of each other in alternating directions (horizontally, vertically and diagonally). The individual layers are then pre drilled at their intersections and “screwed” together (completely metal and glue free) through our proprietary, innovative solid-wood screw made of hardwood. A tapped screw hole in combination with the expansion of the solid-wood screw, through consumption of residual ambient humidity (solid-wood screw has 5-7%, the dimensional lumber 12-18% relative wood moisture content) guarantees that the individual layers are connected to the solid-wood screw creating a static unit. PSP’s are manufactured in thicknesses ranging from 11.4cm to 34.2cm, widths up to 3.0m and lengths up to12.0m to suit a range of strength requirements for applications as wall, ceiling and roof elements. Optionally, the interior can be finished in aesthetically appealing smooth surfaces by pre-drilling the inner layer half-way through.
As a company, PSP’s fit into our top priority of using ecologically responsible products that promote healthy living. Pacific Timberworks is making its mark in the construction industry as an innovator and user of ecological building products to provide and promote a healthy living environment.
