Keder cladding
Steel Frame

Keder Cladding

The cladding is a layered laminate plastic that has been specifically developed to combine light transparency with exceptional heat insulation – perfect for healthy plant growth. It is UV stabilised. 


This means an even spread of light throughout the structure, and much better thermal properties (which means lower heating costs in winter). 

The result of this being optimum growing conditions for your crops with the bonus of a material that needs very little maintenance and is long lasting.

Steel Frame

The frame is made from high tensile British steel and is fully galvanised inside and out. This means no corrosion or degradation in the framework.


The same structural steel is used for some of our accessories/options:

1.       Extreme brace kit: Designed to reinforce the structure primarily for areas of poor weather, be it wind or heavy snow. The extreme brace kit can also be used as a crop rail as it runs the length of the structure.

2.       Crop rails: These are fitted to the frame and sit between two ribs of the greenhouse. They can either be made to fit the entire length of either side or just a 2m section to fit any area.

3.       Roof vents: A manual roof vent is fitted as standard, but an optional automated roof vent is available. This uses a wax plug and piston system meaning automation without the need for electricity. We recommend one for every 4m of greenhouse length.

4.       Through door or disabled access: A free of charge option should you wish to have through access with a door each end, rather than an opening window at one end.

Domestic 3x8 internal with extreme bracing and staging


All timber used is the construction is sustainably sourced and is pressure treated and dipped for maximum longevity. The same can be said of our timber options:

Staging:  With a slatted wooden top and a base which fits over the steel frame, our staging is incredibly strong and each 2m length can withstand up to 18 stone in weight.

Domestic internal with side staging and roof vent.

Please note, domestic range greenhouses are available as a self-build kit or can be installed by our team of professionals at an additional cost.
