The Ultimate Growing Environment

With over 35 years of industry-leading expertise, Keder Greenhouse has developed a solution that is unlike anything else in the horticultural world.

We are manufacturers, designers, and installers of high specification commercial greenhouses. Commercial customers can choose the specifications of design they require depending on their individual growing needs.

A Keder is neither a traditional greenhouse nor a polytunnel; instead, it combines the strengths of both while eliminating their weaknesses.

By using advanced materials and innovative engineering, Keder structures create an unrivalled growing environment that supports true year-round production, making them the choice for professional growers who demand reliability and performance.

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.

Fully Installed & Stress Free

Unlike many greenhouse suppliers, Keder provides a complete, fully installed solution, ensuring everything is fitted correctly and performs as intended from day one.

Our experienced team handles the entire process, from preparing spot foundations at two-metre intervals to the final installation of doors, staging, and vents.

Typical builds are completed within one to four weeks, depending on size, leaving you with a ready-to-use structure.

This professional service eliminates stress and disruption, so you can focus on what really matters - growing.

Flexible Modular Design

Every Keder greenhouse is designed with flexibility in mind, allowing you to create the perfect layout for your growing needs.

Available in standard 8m+ widths with unlimited length in 2m increments, the modular construction makes it easy to adapt, extend, or reconfigure your space over time.

Additional doors, partitions, and crop rails can be integrated seamlessly, while ventilation, staging, and access options ensure your greenhouse works exactly as you need it to.

Whether for small-scale commercial growing, research, educational projects, or large horticultural operations, the adaptability of Keder makes it a future-proof investment.

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

Climate Control and 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 & Finishing Touches

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.
