Greenhouse glazing options

There are a number of glazing materials for greenhouses available, and each has its own advantages and disadvantages. Here's what you need to know about the different types:

Horticultural glass

• Standard value option

• More fragile. The glass can shatter

• Lets in a lot of light

Toughened safety glass

• Strong and resistant to breakage

• Won't shatter - breaks into small bits

• Lets in a lot of light

Polycarbonate glazing

• Strongest option, hard to break

• Offers more insulation

• Lets in slightly less light

Styrene glass

• Plastic. Stronger than glass

• Can discolour over time

What size greenhouse do you need?

Greenhouse installation

Choosing a base for your greenhouse

You'll need a base to secure your greenhouse to the ground. Bases are sometimes included, or can be purchased separately. A base should be the same size or a few cms larger than your greenhouse. You'll also need to anchor your greenhouse to the base. An anchor kit may come with a base, or be sold separately.

    Assembling a greenhouse

    Our greenhouses come in kit form with all the necessary parts included for you to build at home. Greenhouses should be assembled by at least two people for practical and safety reasons. Special care should be taken when working with extruded aluminium and handling glass, so always wear protective gloves and goggles. 

      Best spot for a greenhouse

      • Somewhere flat, not bumpy or on a slope.

      • Away from trees to avoid shade and falling branches.

      • Near walls or hedges to offer protection from the wind.

      • Close to your house if you need mains power for lights and heating.

      • Close to a tap for water.

        Greenhouse shelving

        Once your greenhouse is in place, you'll need to kit it out with benches, shelving and racks. This will help maximise your growing space and provide extra storage for your gardening supplies.

          What to grow in a greenhouse

          One of the biggest benefits of having a greenhouse is that you can grow all year round. From vegetables to herbs and flowers, there is no limit to what plants can be grown.
