Description
Guntis Sosins and colleagues characterise aspen wood after heat treatment under pressure. Their study from twenty twenty-four uses a pilot chamber with nitrogen gas. Thermal modification improves wood stability without chemical preservatives. A closed, pressurised process may treat wood more evenly.
Boards were heated for up to three hours at moderate temperatures. Treated wood lost mass and shrank in every direction. Moisture uptake and swelling dropped to less than half of untreated levels. Stiffness rose slightly, while bending strength dipped modestly. Hardness and water capacity of cell walls also shifted. The trade-offs look favourable for building uses. Aspen, a fast-growing wood, gains durability from the process.
