Frequently asked questions



What is the lead time, for installation?

For an installation of a greenhouse typically within 4 weeks of order confirmation, for larger projects or full commercial typically within 2 months.

What makes your greenhouses different to others?

Our greenhouses have a life expectancy of 20+ years and require almost no maintenance. There is no need for shading, the light is diffused so there is no scorching to the plants.

The cladding ensures no shadows are cast so plants don’t struggle for light.

The heat retention is superb – like a duvet for your plants.

Our extremely strong steel tubing is galvanised inner and outer – meaning they won’t rust from the inside.

The greenhouses are designed and manufactured to withstand the strongest wind speeds experienced in the whole of the United Kingdom, including the Scottish Highlands and islands.

They are totally safe when compared to glass, there is nothing to shatter.

If accidently damaged, they can be repaired just by the damaged section.

They can be extended – so they can grow with you!

How is the greenhouse secured?

4m wide and above greenhouses have foundation as standard, these are 50cm cubed blocks at every 2m point around the base of the greenhouse.

Who does the foundation work?

All the foundation work is done by our dedicated installation team. 

Can I move the greenhouse?

They can, but please be aware that any Keder Greenhouse 4m wide and above have foundations that require specialist Keder knowledge to do so.

How much room do you need around the greenhouse to be able to build it?

4m wide and above greenhouses must have a minimum of 1m clear access all around the structure for movement of mechanical equipment.  

What ventilation options are there?

4m wide and above greenhouses have manual drop-down side vents as standard, which can be upgraded to electric thermostatically controlled if required.

This system of opening from the top down ensures the best ventilation and removes excess heat faster.

This system also means that the soil at ground level is not dried out quickly.

Should you be looking at a multi-bay option, we can look to lift the mid-bay higher than the outer bays to allow higher vents in the eaves.  We call this our cathedral system.
