Thermo-treated wood

Thermowood production – as scientifically based industrial timber modification – has been in active use for more than few decades, while in recent years its demand has gained surprising momentum.

ThermoWood is essentially natural wood, processed with heat (180–215°C), steam and water in specifically adjusted and controlled heating cycles. Being entirely ecological and free of any chemicals, the treatment process irreversibly modifies physical and chemical properties of timber resulting in extremely durable and exceptionally sustainable material, friendly to both humans and nature. The modification also improves its dimensional stability and thermal insulation qualities.

Unlike ordinary wood, ThermoWood contains no natural resins nor formaldehydes. It has a pleasant scent, its weight is lighter, and texture subtler, smooth to touch. After undergoing a full processing cycle, ThermoWood acquires its typically warm caramel tint. The surface can be safely exposed to the elements outside, although, with time, the natural UV radiation will transform the colour to greyish hue.

ThermoWood is irreplaceable in environments with dramatic temperature and humidity fluctuations, which makes it an ideal material for outside cladding, decking, balconies, fences, and saunas. Due to its aesthetically pleasing appearance, eco-friendliness, and dimensional stability, ThermoWood is an increasingly popular choice in contemporary interior design.

We provide standard and custom profiles with improved durability, a darker brown tone for use in interior and exterior applications. Thermowood is resin and pith free, you can easily apply glue, paint, oil finishing or surface treatments like a fire-retardant coating or simply leave it natural.
