Norfolk Greenhouses are available in two models; SPACESAVER and ULTIMATE. The frames for which are identical in material (galvanised steel) but differ in size.
Our greenhouses are clad in glass clear panels of semi-rigid sheet cut to size, with 5 year guarantee against deterioration. Flexible PVC has the same heat retention, ultra violet stabilisation, and safety properties, but looks just like glass. Why change a good idea that has worked well over the last 40 years?
In addition, our Greenhouses have translucent twin wall roofing panels for added insulation and direct sunlight protection.
