Advanced Cladding Technology
At the heart of every Keder greenhouse lies our unique 9-layer bubble laminate 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, our tubing is almost twice as strong as standard alternatives, with a minimum yield strength of 350 N/mm².
Each length is pre-galvanised inside and out, providing complete protection against rust and corrosion.
With steel sourced from trusted UK suppliers and full traceability on every batch, you can be confident that your structure is both sustainable and built to withstand the test of time.
Engineered for Extreme Conditions
Keder greenhouses are proven to withstand some of the harshest conditions nature can throw at them.
They 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.
This resilience means growers can operate with confidence, knowing their crops and investment are protected all year round.

Sustainable and Built to Last
Strength and sustainability go hand in hand with Keder’s approach to design.
The frames are manufactured from locally sourced, high-strength ZN35 steel and complemented with sustainably sourced timber that has been pressure treated and dipped for maximum durability.
Optional 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.
Combined with integrated 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.
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.
Doors & Gutters
The details make all the difference, and every Keder greenhouse includes high-quality finishing features that enhance both function and longevity.
Sliding doors, made from galvanised steel box section, provide easy access while maintaining strength and security.
Integrated guttering is manufactured from pre-galvanised steel sheets and runs the full length of the structure, offering reliable rainwater collection and protection against weathering.
With a low ridge height of just 2.9m, Keder greenhouses are also suitable for sensitive sites, including areas of natural beauty or locations where planning permission may be an issue.
