Durable Thermowood® decking boards

Thermowood decking
Thermowood® decking

 

​​​​​​​​​​​​​​​​​​​Metsä Wood’s ThermoWood® decking board is made from Scandinavian softwood. A chemical-free heat treatment is applied to the decking to improve its performance, making it naturally weather resistant in addition to being environmentally friendly. ThermoWood® deck boards can be left to weather naturally or a deck oil can be applied to maintain the rich colour.

ThermoWood® deck boards are grooved on one side and smooth on the reverse. Please refer to the table below for more details.

Our decking is PEFC certified and has a 15 year guarantee against rot and fungal decay, subject to correct installation and treatment of cut timber. ​​
