 Thermal modification technology can be applied to just about any wood species to enhance dimensional stability and resistance to decay. Economically, it makes sense to thermally modify readily available species that are not naturally durable. Cambia's technology partner, Perdure through Canada's Wood Products Research Institute (Forintek Canada Corp) has studied how thermal modification affects the performance characteristics of wood. Please see the attached PDF illustrating the mechanical performance of thermally modified jack pine to untreated jack pine and western red cedar. Also, see the PDF illustrating the decay resistance of thermally modified trembling aspen compared to untreated trembling aspen and CCA pressure treated southern yellow pine. Mechanical strength and resistance to decay roughly correlate to density. Trembling aspen is a low density hardwood , prone to decay. Jack pine is a medium density softwood used for construction and pulp. |
