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.

6x8 Palram Canopia Harmony Green Greenhouse Clear Polycarbonate

Good value compared to glass greenhouse. However bear in mind that these are lightweight and will move around in strong winds so need to be anchored down. In my view it needs more than one opening as they suffer from condensation.

6x4 Palram Canopia Harmony Green Greenhouse Clear Polycarbonate

I love my greenhouse! It's perfect for me. The transparent look of glass without the fear of it being smashed! OK, the panes are a little wobbly but my tomato plants didn't mind that last year and it withstood its first winter in Yorkshire, so I'm happy.

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.
