Handling and working with ThermoForest Thermowood is much like working with conventional lumber. No special tools are required, just sharp blades; for smooth cuts and to prevent the fine grain from being ripped or torn. Effective respirators, as well as eye protection, are recommended for any sanding or cutting operation.

Dr. Mat Leitch and the Wood Science department at Lakehead University reports that, “Processing at temperatures between 150C and 200C does not decrease the mechanical qualities as is reported for other thermowood systems.”

As with other products, it is recommended that in some cases, depending on the location of the attachment/joint and the species of the stock, pre-drilling may be required.

The use of deck screws is also recommended to reduce the risk of splitting in some species. However, in most applications, air nails are practical and efficient fasteners, as twisting problems found in traditionally treated lumber is not a problem.

Thermowood absorbs water and water based glues more slowly than untreated wood and may require longer “setting up” times. Common adhesives and two-component bond agents are recommended for use when gluing heat-treated wood.

Like any natural wood product, Thermowood is susceptible to graying when exposed to sunlight (ultra-violet). If maintaining the natural color is desired, protecting the wood with a coating of commercial UV protection is recommended.
