The functionality and versatility of wood-based composite panels give them universal appeal. When properties such as high strength, light weight, good insulation and ease in use are required, wood-based composite panels become the ideal choice for many applications.

Although wood is widely used as a building material, it has certain natural shortcomings. Notably, wood is inclined to swell and shrink in response to changes in relative humidity. Wood is also susceptible to degradation because of attack by microorganisms, like fungi, and is therefore not naturally durable.

These shortcomings have limited the use of solid wood and wood composites in many markets and applications. Poor durability and dimensional stability will, for example, cause wood panels to crack and delaminate over time. The good news is that composites containing acetylated wood chips, particles, fibres, etc. demonstrate to have superior dimensional stability and durability, even in extreme weather conditions, meaning they can now be used in situations and applications where normal wood panels cannot.

Renowned institutes both inside and outside Europe have extensively tested and evaluated the Tricoya panels and conclude the performance is so outstanding the material safely can be used in very adverse exterior environments. Note that configurations may vary to some extent, as wood feed stocks, resin systems and panel forming conditions have a certain influence on the dimensional stability and durability of the end product.
