Heat Treated Wood

Eco-friendly thermowood market is growing in popularity over the years, leading to tens of thousands of cubic meters of raw material being processed every month in the world. There is demand, so supply is growing rapidly. As the heat treatment of wood emphasizes defects and defects in the quality of the wood, all products are made from high quality raw materials. The ash used in production grows in well-maintained North American forests, which provide good growth conditions and high quality drying standards. And the raw material used for the production comes from spruce and pine wood from northern and central Finland. In this part of northern Finland, slow growth gives the wood a high density and has a relatively small branch crown.

Types of wood used

• The main species – Pine (Pinus Sylvestris) and Spruce (Picea Abies)

Pine grown in northern Finland is the main raw material. Only wood with healthy twigs is used to ensure the highest quality of the finished product. As a result, production is well known and trusted for its superior quality.

The properties and quality requirements of spruce wood used in production are very similar to those of pine and its requirements. The most commonly used spruce wood is in the production of painted products, structural joists and other similar products. In terms of production, knots are the main difference between pine and spruce: in spruce wood, knots are smaller but relatively firmer, which makes them less susceptible to damage during the wood production process.

• Other species – knotless Radiata Pine (Pinus Radiata) and knotless Canadian Ash

Many other types of wood are suitable for thermal modification. The product range includes two types of knotless wood also, thermally modified Radiata pine and Canadian ash. Radiant pine is used for the production of exterior finish in cladding and siding and interior decoration products. Canadian ash is denser and harder than softwood and is ideal for decking and flooring products as well as facade finishing.

Quality of heat treated wood

All of our products are of the highest quality, which is achieved by manufacturers combining know-how, modern technology, high-quality raw materials, well-trained staff and systematic quality control. Innovation and continuous product improvement play an important role in the choice of products on the market. Many different types of wood have been tested since the start of the thermal process. To find the most suitable wood for heat treatment. Research is an ongoing process aimed at expanding high quality products that fully meet the expectations and choices of end users.

Therefore, long-term cooperation and continuous positive feedback from leading timber traders in key markets across Europe, USA, Japan, Australia, etc. Ensures that heat-treated wood products are environmentally friendly, high quality, long lasting, durable and rewarding. To this day, thermowood products are the recognition of quality standards!
