Superior decay resistance
In classifying Stellac® Thermally Modified Timber (TMT), we have taken as our guidelines the European Standards covering natural durability. In short, this mean that the Stellac® process improves decay resistance by decreasing moisture content and minimizing the nutritive sources for decay and fungi.
As a result, Stellac is the only company that is able to thermally modify the timber to fulfill the criteria defined in the EU standards relating to natural durability. The timber processed by Stellac technology is classified in 5 classes: T5 (lower level - 190 C), T4, D3, D2 and D1 (higher level - 250 C) where for instance thermally modified spuce and pine in classes D2 and D1 fulfill the criteria defined the EU standard's for hazard classes 4 and 5. Tests with pine have shown that Stellac Wood processed at our D2 levels can be used in direct ground contact or exposed to fesh water.

With Stellac’s precise and unique process control system, you will enjoy a high level of flexibility and produce products that meet the highest of requirements and expectations when it comes to durability. |
The graph below shows how the StellacWood durability is improved at each treatment levels. Durability tests made with Spruce (Picea abies) and Pine (Pinus Sylvesteris) show that untreated wood loses its mass by 70% where Stellac Wood at D2 level loses its mass only only 5%. At D1 level, wood processed with Stellac technolgy remains 100% intact.
Increased dimensional stability
As a result of low equilibrium moisture content and low water absorption, the deformations usually caused by fluctuations in air humidity are reduced significantly with the Stellac® process. This will increase customer satisfaction, for instance by eliminating the gaps between floor tiles normally caused by shrinkage.
The graph below shows how dimensional stability is affected at each thermal modification level of the Stellac® process. As an example, tests results for Spruce (Picea Abies):
Matching colors with your needs
Stellac enables you to achieve a wide range of color tones using a single wood species. With Stellac’s precise process control system, you will enjoy a proven homogeneity of colors within each kiln load; meeting your highest quality requirements, load after load. (PICTURE)
No more resin-related issues
Wood resin is dried out during the Stellac® process, giving you an excellent base for further processing, such as coating.
