Advanced Cladding Technology
At the heart of every Keder greenhouse lies our unique 9-layer bubble laminate plastic cladding. This ultra-strong material creates thousands of light prisms per square metre, diffusing sunlight evenly across the growing area. The result is no scorch, no shadows, and consistent light levels that encourage healthier, more uniform growth.
Unlike glass or single-skin plastic, the bubble structure balances heat retention with transparency, helping to stabilise temperatures and reduce the risk of condensation - giving plants the ideal environment in which to thrive
Superior Steel Framework
Every Keder greenhouse is built around a robust steel framework that is designed to last for decades.
Manufactured from ZN35 high-tensile structural steel, with a minimum yield strength of 350 N/mm². All steel tube is pre-galvanised inside and out, providing complete protection against rust and corrosion.
With steel sourced from trusted UK suppliers due to their high standards of manufacture and full traceability on every batch.
Hoop spacing is standardised at every 2m across the full range of our structures with cross bracing on every hoop as standard.
Engineered for Extreme Conditions
Keder greenhouses are windproof up to 120 mph (proven) and have been tested under real-life heavy snow load conditions, offering unrivalled durability in challenging environments.
With a thermal R-value of 1.7, they also deliver excellent insulation and energy efficiency, making them cost-effective to heat through winter while staying cooler in summer.

Sustainable and Built to Last
Strength and sustainability go hand in hand with Keder’s approach to design as doors and gutters are integral to the structure
Sliding doors are made from galvanised steel box section, providing easy access while maintaining strength and security.
Full length galvanised gutters for effective rainwater harvesting.
Every part of the greenhouse is engineered to last while working with the environment.
Ventilation
Good ventilation is essential to plant health, and Keder greenhouses come equipped with efficient systems as standard.
Manual outer wall vents, operating on a simple and effective bob-weight system, encourage airflow from the top down to maintain a stable growing environment. We optimise the ventilation system based on the design as standard.
For larger or more advanced setups, additional options include automated side vents, central roof vents for multi-span structures, and end vents for further control.
Thermostatic electric units can also be integrated, allowing vents to open and close automatically based on your programmed temperature settings, creating an ideal microclimate with minimal effort.
Optional Extras
The details make all the difference, and every Keder greenhouse includes high-quality finishing features that enhance both function and longevity.
Optional extras include
-
One or two-tier timber staging fits neatly into the steel framework and is built to withstand up to 114 kg per 2m section, providing growers with strong, reliable working surfaces.
