Thermo ash decking board

THERMORY® Collection offers decking for exterior use.

The durability of THERMORY® decking boards is achieved by intense modification, which produces an environmentally friendly alternative to both tropical hardwoods and impregnated wood. Thermal modification significantly improves wood's resistance to mold and rot.

THERMORY® decking can be installed using several visible and invisible installation systems.

Thermal modification is a computer-controlled process carried out in a special kiln at high temperatures. Only steam and heat without any chemicals added result in increased stability and durability, extending the lifetime of the wood considerably.

Natural wood feels warm and inviting in both interior and exterior design. Especially for outdoor use, it is important to choose wood that is not only attractive but also durable. Thermally modified wood offers precisely that. The stability and durability of Thermory Ash are guaranteed by a thermal modification process called Intense, during which the wood gets heated up to 215 degrees.

Thermally modified wood is characterized by an even dark tone and beautiful wood grain. 

Without protective maintenance, even thermally modified wood will eventually turn silver-grey, although the material will retain its weather-resistant properties. Natural grey cladding is popular in places such as Scandinavia, where they do not put emphasis on maintaining the original color of the wood and the weathered tone actually becomes part of the exterior design. However, it is possible to preserve the color by regularly coating it with UV-protection oil.

Thermory Ash has become an integral part of the work of architects.

Process

• The process uses only heat and steam (no chemicals)

• Industry's top thermal modification kilns

• Computer controlled process

• Two modification levels: 
  • Medium (peak temperature 190º C)

  • Intense (peak temperature 250º C)

Stability

• Higher dimensional stability 

• Lower equilibrium moisture content

• Less likely to warp, bow, cup, twist, or shrink

Durability

• Highest possible durability of natural wood 

• Thermory pine has durability class 1

Responsibility

• Chemical-free thermal modification process

• Sourced from well-managed American and European forests

• No rainforest woods

• No plastic

• No toxic waste
