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.

The Palram - Canopia Mythos 6x6 in Green features easy to build construction with full Twin Wall Polycarbonate throughout.

The Mythos 6ft x 6ft greenhouse is packed with some excellent features. The Twin Wall Polycarbonate roof panels both defuse harmful UV rays while adding insulation to the greenhouse which also features a slide in system which helps with wind resistance and helps stop glazing popping out in windy conditions. There is also a proper opening door with latch.

This Green Palram - Canopia Mythos 6x6 has a single opening roof vent for ventilation, an outward opening door, aluminium base and integral gutters.

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 Greenhouses.

Slide-In Glazing System

Palram - Canopia Greenhouses benefit from this neat glazing system where the polycarbonate just slides into a groove within the frame to make it secure.

Integrated Gutters

You get integrated gutters on both sides of the greenhouse. Simply attach a length of hosepipe with a jubilee clip to the universal fitting!

Locking Outward Opening Door with Latch

Easy to secure with a padlock.

6x6 Palram Canopia Mythos Green Polycarbonate Greenhouse

When panels came out during windy weather, I ended up employing a glazing company to ease the panels back into place. They then used silicone sealant on all the panel edges, inside and out, to try to keep them in the frame. If thinking of a greenhouse, stick to glass and ignore the polycarbonate panels. This has been an expensive disaster for me.

Greenhouse Buyers Guide 2025

This comprehensive 2025 guide helps you choose the perfect greenhouse by exploring crucial factors from size and materials to optimal location and essential accessories.

Make an informed decision by understanding how to assess your needs, compare material pros and cons, and ensure proper ventilation and positioning for a thriving greenhouse.

How to Prepare the 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.

Placing your greenhouse in the right spot makes all the difference between thriving plants and disappointing results. As a greenhouse specialist who's spent 15 years helping UK gardeners optimise their growing spaces, I've seen first-hand how position affects everything from temperature regulation to plant health.

Let me share what actually works in our unique British climate. The greenhouse position might seem like a minor detail, but it's one of those things that can make or break your growing success. I made this mistake myself when I first started - my poorly positioned greenhouse meant I was fighting an uphill battle with inadequate light and temperature fluctuations.
