Global Heat-treated Wood Market Strategic Research Report

Scope of the Report

The global Heat-treated Wood market size is predicted to grow from US$ 476 million in 2025 to US$ 649 million in 2032; it is expected to grow at a CAGR of 4.6% from 2026 to 2032.

Heat-treated wood is the wood or limber that has been exposed to high temperatures.

There are usually two classifications for the “Heat Treated (HT)” in the market:

The first one is based on the recommendation of the International Standards for Phytosanitary Measures (ISPM) 15, the wood that is used to package materials, such as pallets, require a less intense temperature for treatment. Generally, the temperature is around 133°F (56°C), and the duration is about 30 minutes. In this case, HT wood can stop the spread of insects and disease through international trade.

The second one is thermal modification of the wood. It needs to treat the wood for a certain period of time in a low oxygen environment of 160°C ~ 230°C. This time periods can reach to 96 hours. This heat treatment can improve the dimensional stability of the wood, remove or slow down the internal stress of the wood, and at the same time improve the preservative properties of the wood.

This report focus on the second type of heat-treated wood. For this type of HT wood, several heat treat processes have appeared on the market. Among them, the ThermoWood process, which comes from Finland, has achieved a great breakthrough in business, and it is also the most widely used process.

Thermory, Oy Lunawood and Ducerf Group are the top 3 companies in global heat-treated wood market and account for about 60% of total market share. Geographically speaking, Europe is the largest producer of heat-treated wood, holds a share over 60%, followed by North America. In terms of type, softwoods segment holds an important share of about 60%. In terms of application, exterior applications segment account for over 60% of the global share.

Heat-treated wood is mainly classified into the following types: hardwoods and softwoods according to the tree species. Softwoods segment is the most widely used type which takes up about 65.5% of the total revenue market, it is mainly due to the big players are located in Nordic region and have large amount of pine and spruce.
