STORM PROOF
GREENHOUSES
With over 35 years of industry-leading expertise, Keder Greenhouses provide a revolutionary solution for expert growers, smallholders, and domestic gardeners.
Unrivalled in design, a Keder is neither a traditional greenhouse nor a polytunnel.
Instead, it combines cutting-edge materials and advanced engineering to deliver an exceptional growing environment.
At the heart of every Keder greenhouse is its unique 9-layer ultra-strong bubble laminate, creating thousands of light prisms per square metre. This ensures no scorch, no shadows, and the perfect balance of light diffusion for optimal plant growth. Coupled with a sturdy high-tensile steel support frame, Keder greenhouses are windproof up to 120 mph (proven), making them a robust and reliable choice, even in extreme weather.
Thanks to its high-performing thermal R-value of 1.7, Keder greenhouses offer a true year-round growing proposition.
Whether you're an expert horticulturist, giant vegetable grower, smallholder, crofter, or keen gardener, a Keder greenhouse will stand the test of time - lasting over 30 years.

Our Domestic range of greenhouses caters for virtually every size of garden.
Its unique modular system can be extended as your requirements increase and can also be relocated if required.
We can provide our 2m and 3m wide greenhouses as either self build kits for the competent DIY enthusiast (we provide a full instruction manual and video) or we can offer an installation service by our professional construction team for an additional charge + mileage + accommodation if required.
Our cold frames are supplied as a self build kit basis only.
Made from high tensile steel frames, paired with our advanced cellular cladding system, this ultra strong combination offers an environment far safer and longer lasting than a traditional glass greenhouse and far more superior than ordinary polytunnels.

David Domoney explaining the benefits of a Keder
"We’ve had several greenhouses and polytunnels over the years but NOTHING like a Keder Greenhouse, it is a premium quality product. We did a lot of research prior to the investment and particularly liked the videos showing the construction process and the materials used."
"We needed a polytunnel that would withstand the winter gales here on Orkney. We came across the Keder Greenhouses website and were immediately impressed with their site, choices and customer service. We settled for a 3m x 8m design with extra bracing kit. The greenhouse arrived on one single pallet which amazed us, the whole thing was packed to perfection. My husband managed to erect the greenhouse all by himself with very little help from me. They went above and beyond to ensure that we were happy and pleased with our purchase. So, if you are thinking of buying a polytunnel/ greenhouse I would strongly advise you to check out their website and contact them for any extra information."
"We put up our 3x8m Keder this time last year. It has survived a rather long Shetland winter and is filling up nicely for its first full growing season. It’s enabled me to get off to a good start with seedlings and over wintering cuttings coming along nicely. Although our growing season is short we make up for it with longer days, the Keder fabric maximises the light and helps retain heat well. I was a little worried about ventilation as it can get a little breezy at 60 degrees north but even with gusts of 30mph today I’ve had the doors open all day and all is well. Overall, I’m very happy with the Keder Greenhouse and if money were no object I’d certainly get another."
