The Palram - Canopia Balance 10x20 gives you a bright, sturdy growing space with room to work in comfort.
The clear single wall polycarbonate side panels pass over 90% of daylight so plants get the light they need. The twin wall polycarbonate roof spreads that light and blocks harmful UV rays while adding insulation. The natural silver powder coated aluminium frame never needs painting.
The Balance uses a sliding panel system, so there are no fiddly glazing clips. The panels slide into the profiles and hold firm in wind. When we build one this size, we fit the extra support beams and corner plates first to keep the frame square.
The galvanised steel base plinth is included and bolts down through ready made anchor holes. The double doors are wide, lock shut and sit on a low threshold, so you can wheel a barrow straight in. 5 roof vents keep air moving on warm days.
Not Suitable for Windy or Exposed Positions
If you are in a windy or exposed position we recommend a Glass Greenhouse, preferably a Toughened Glass Greenhouse.

Frequently Asked Questions
-
What are the different types of Polycarbonate Glazing?
Clear Polycarbonate: This polycarbonate is completely clear like glass. It is very thin at 0.2mm, but extremely tough and shatterproof.
Twin Wall Polycarbonate: This polycarbonate is virtually unbreakable and high impact resistant. They are slightly opaque, preventing strong sunlight exposure, yet offer 80% light transmission with high thermal insulation. The panels are 100% UV protected and will not discolour, fracture or shatter.
-
Is polycarbonate glazing strong enough?
Yes it’s shatterproof and high impact resistant. However, as polycarbonate is very light, we do not recommend placing these greenhouses in exposed areas with high wind.
-
Does the greenhouse come with a floor?
No, there is no floor or base. These greenhouses are ideally to be placed on a concrete, slab or decking base.
-
How do I secure the greenhouse to my foundation?
We recommend securing the greenhouse to a hard, level surface (concrete, slabs, or decking) immediately after construction. This is essential for the stability and rigidity of your new greenhouse. You can use a screw and a washer through the compatible pre-drilled holes in the greenhouse frame into a raw plug in your concrete/slab surface.
-
Will you let me know when the delivery is?
Yes, you will be notified by text where you can then pick which delivery day suits you. Easy!
How to Prepare Ground for a Greenhouse Base
A solid base is the backbone of any greenhouse. You might think skipping this step saves time, but trust me?I've seen plenty of greenhouses fail because of poor foundations. A dodgy base causes more headaches than you'd believe.
What happens with a bad base? Glass cracks. Doors jam. The structure twists. Water pools where it shouldn't. And fixing these problems costs way more than doing it right first time.
Best Position for a Greenhouse UK: Expert Placement Guide 2026
The best position for a greenhouse in the UK is south-facing with the ridge running east to west. Keep at least 2 metres from buildings and trees, on level ground with good drainage. A south-facing 6x8 greenhouse runs 3-5 degrees C warmer than the same model facing north.
