Keder Greenhouse – The Strongest Greenhouses in the UK

Keder Greenhouse is a UK-based designer, manufacturer, and installer of the strongest, most resilient greenhouses on the market, engineered as a complete premium growing system. Every Keder structure is purpose-built to endure the UK’s harsh and unpredictable weather while delivering consistent, high-performance growing conditions year-round.

At the core of each greenhouse is advanced 9-layer bubble-laminate cladding, designed to diffuse light evenly across crops while providing superior insulation and UV protection. This material optimises plant growth by improving light penetration and maintaining stable internal temperatures, even during colder months.

Supporting the cladding is our heavy-duty ZN35 galvanised high tensile steel frame, rigorously engineered and wind-rated to withstand speeds of up to 120 mph. This exceptional structural strength makes Keder Greenhouses the strongest greenhouses in the UK - capable of standing up to extreme weather, high snowfall loads, and exposed locations without compromising safety or performance.

With an impressive R-value of 1.7 insulation, Keder’s system dramatically reduces heat loss compared to traditional glass or single-skin plastic structures. The result is lower energy demand, reduced running costs, and a more stable growing environment that supports reliable crop production throughout all seasons.

Unlike standard greenhouses, Keder’s approach treats the structure as a fully integrated growing solution rather than a simple shelter. The combination of ultra-durable materials, precision engineering, and professional installation ensures each greenhouse delivers unmatched longevity, reliability, and productivity.

From commercial growers to research facilities and high-performance horticultural projects, Keder Greenhouse provides the strength, stability, and growing performance professionals rely on - making us the clear choice for those who want the strongest greenhouse systems in the UK.
