All Swallow greenhouses are now made from Thermowood.
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.

Beautiful, well made, perfect!

We are so delighted with our new potting shed. It is much more spacious than we had imagined and feels really well constructed and sturdy. The wood is beautiful and it has made our whole garden feel much nicer. Self opening windows are a great bonus, and the installation team were great. Excellent service, would highly recommend!
