Black Thermowood

Our black Thermowood is an excellent quality product which is provided ready to fit and has an expected 10 year maintenance period. This makes it an ideal solution for your project if you don’t want to treat and re-treat the wood yourself.

The wood is dried and all of the moisture is taken out of it, which makes it as stable as possible and means the timber won’t move very much because it can’t dry any further. Thermowood is weather resistant and remains stable in temperatures ranging from -40o to 40o.

The timber itself is a high grade softwood which contains sound knots and no resin. The finished product is highly resistant to decay as long as it is used above ground and not in constant direct contact with soil and/or water.

The black topcoat which is applied forms a layer of film over wood and helps to prevent water penetration. This treatment adapts to the climate allowing the wood to breathe.

The timber is provided in a T&G profile which can be fitted either horizontally or vertically. The profile is designed to be secret nailed along a small groove in the wood. The timber can still split under nailing, so pre-drill your holes and then rest the board on the nail/screw head (make sure you use stainless steel).

As we hold the boards in stock we can usually get the timber out to you in 7-10 working days. The boards are usually supplied 4.5m and longer although that is subject to change depending on availability (we don’t offer cross-cutting on these boards).

We also have a Painted Black Featheredge Cladding option available online.
