Co2 Thermotimber

In 2018 we decided to add another timber to our portfolio.

We assessed the durability, sustainability and cost to our customers of several timbers over a period of about 12 months and decided that Co2 Thermotimber (Thermowood®) would be another timber for us to supply to customers who`s requirements took them outside of our standard product range.

Co2ThermoTimber is produced by heat treating Finnish grown pine and spruce to temperatures in excess of 200 degrees centigrade. During the heat treatment, chemical and structural changes occur within the timber which alter and improve some of its basic characteristics. The resulting product is an altogether more durable and stable timber, an ideal cladding material for use in exposed areas such as external walls.

Technical information on Co2ThermoTimber

Durability - ThermoTimber is rated as class 2 which is durable. (BRE give a life span rating for this product of around 30 years).

Dimensional Stability - One of the benefits of this product is its stability, the thermal modified process reduces the moisture content in the board ensuring less movement.

Thermal Conductivity - Thermo has a thermal conductivity of around 20% less than standard softwoods. The thermal conductivity is y10 to 0.099 W/(m K).

Density - The density of this material is between 350 kg m3to 480 kg m3 when dried to a moisture content of around 6%.

Workability - While nail/screw holding capability on this product is around 20% less than usual due to the altered state of the cell wall caused by the heating process.

We source our timber from FSC/PEFC certified plantation we aim to keep our carbon footprint to a minimum and encourage sustainable practices.

Our Co2 Thermotimber is imported and we can supply four cladding profiles. We have decided to create a new website which displays prices and technical information.
