Heat and steam are used to thermally modify the wood to produce an exceptionally strong and durable wood that is perfect for outdoor use.
This process is achieved using natural methods and is non-toxic and chemical free, with one of the many benefits being improved insulation well suited for greenhouses.
After treatment the wood is a beautiful consistent colour that will last far longer than normal treated timber.

Swallow 4 x 8 Lean-to
Saturday, 24 December 2016  |  George

Pleased with almost everything.
Product is of good quality.
The lads who installed it were excellent
Two minor criticisms. One, condensation runs down inside the glass and pools on the frame of the outer wall. Two, the dimensions sent for the 'goalpost' are misleading. the height given of 8' 6" for the ridge is correct, but it is not made clear that the ridge sits on top of the green house so the goalpost needs to be no more than 8' 4".
