What is Thermally Modified Wood?

Thermally modified wood is solid timber enhanced through a controlled heat treatment process using only heat and steam, without chemicals. The process is carried out in a fully automated thermal kiln system imported and installed by Finnish specialists, ensuring precise and consistent performance.

Equipped with core wood sensors, the system enables real-time monitoring and automatic control throughout the treatment cycle, typically ranging from 24 to 60 hours depending on species and initial moisture content.

The high-temperature, oxygen-reduced process degrades hemicellulose and permanently alters the wood’s hygroscopic structure. As a result, equilibrium moisture content is reduced to approximately 4–5%, with significantly lower moisture uptake under ambient conditions.

These modifications improve biological durability, dimensional stability, and resistance to moisture.

Controlled kiln drying ensures uniform moisture content and stable performance during fabrication.

Pricing

Red Grandis offers a cost-efficient and sustainable alternative hardwood, combining reliable performance with consistent plantation supply.

Thermal Modification Process

Step 1: Drying

Timber is gently dried at up to 130°C to remove moisture and prepare for safe high-heat treatment.

Step 2: Heating

Wood is heated to 185–230°C in low-oxygen steam conditions, triggering permanent structural and chemical changes.

Step 3: Modification

Cell structure is altered to reduce water absorption, improve decay resistance, and eliminate the need for chemicals.

Step 4: Cooling & Reconditioning

The timber is gradually cooled, and moisture is reintroduced with steam to stabilise it.

FAQs

Frequent Ask Questions about Noawood (Thermally modified wood)

What is thermally modified wood, and how does it differ from untreated wood?
Thermally modified wood is timber that has been treated at high temperatures (typically above 170°C) under controlled conditions to improve its durability, stability, and resistance to moisture.
In contrast, untreated wood refers to timber that has not undergone any modification or chemical treatment. It is far more susceptible to rot, fungal growth, insect attack, and dimensional instability when exposed to outdoor conditions.
The high-temperature treatment changes the wood’s cellular structure, reducing its ability to absorb moisture and making it less hospitable to fungi and insects. This results in significantly improved resistance to decay, warping, and biological degradation.
Maran Timber offers thermally modified wood under its Noawood product line, which includes options for both decking and cladding. These products are engineered to deliver premium performance in all-season climates while offering a sustainable alternative to traditional hardwoods.
Noawood uses select Malaysian tropical hardwoods, including Merpauh for decking and Meranti for cladding, both of which are thermally modified to enhance their strength and weather resistance. These species are chosen for their availability, workability, and suitability for thermal modification.
Noawood is ideal for exterior applications due to its superior durability and dimensional stability. Common uses include decking, cladding, facades, soffits, fencing, and outdoor furniture, especially in environments exposed to moisture, sunlight, and temperature fluctuations.
