Polycarbonate Greenhouses
Polycarbonate greenhouses for sale
Our range of polycarbonate greenhouses for UK gardens combine twin-wall polycarbonate glazing with durable aluminium frames to create practical growing spaces for gardens of all shapes and sizes. Whether you're looking for a compact design or a larger greenhouse with polycarbonate panels, you can compare different footprints, door configurations and glazing thicknesses across the range.
From straightforward entry-level models to larger greenhouses with thicker twin-wall panels and additional features, you can compare the options below and find the right greenhouse for your garden and growing plans.
Why choose a polycarbonate greenhouse?
Polycarbonate is a practical alternative to traditional glass greenhouse glazing. The twin-wall panels used across our range consist of two layers with air spaces between them, helping to provide insulation while still allowing natural light into the greenhouse.
Polycarbonate is also lightweight and resistant to impact, making it well suited to everyday use in the garden. Combined with an aluminium frame, it provides a low-maintenance greenhouse construction designed for long-term outdoor use.
With panel thicknesses ranging from 6 mm to 16 mm depending on the model, our range gives you the flexibility to choose a greenhouse specification that suits your requirements and budget.
Polycarbonate greenhouse panels and glazing
Our greenhouses use twin-wall polycarbonate panels rather than single-sheet glazing. The two layers are separated by internal channels, creating pockets of air within the panel. This construction helps improve insulation compared with a single sheet while keeping the glazing lightweight. The translucent panels also diffuse incoming light rather than creating the completely clear appearance associated with traditional greenhouse glass. Across the current range, models are available with twin-wall sheets from 6 mm to 16 mm thick. The exact thickness depends on the greenhouse and product range you choose.
Durable aluminium frames
Polycarbonate glazing is combined with aluminium frames across our greenhouse range. Aluminium is well suited to outdoor greenhouse construction because it is lightweight, requires relatively little maintenance and does not rust in the same way as untreated steel. Frame design, dimensions and included components vary between models, so it is worth comparing the individual product specifications as well as the glazing thickness when choosing your greenhouse.
Choosing the right polycarbonate panel thickness
Polycarbonate panel thickness varies across our greenhouse ranges, giving you several levels of specification to choose from.
Our Standard and Hobby greenhouse models shown in the range use 6-8 mm twin-wall sheets. Expert models use 10 mm twin-wall glazing, while selected Pro greenhouses are available with 10 mm, 12 mm or 16 mm twin-wall panels.
As a general rule, thicker twin-wall panels contain larger insulating air spaces and provide a more substantial glazing construction. The best option for you will depend on how you plan to use the greenhouse, the specification you want and your budget. Always check the individual product details before ordering, as glazing thickness varies by model.
Polycarbonate, glass or polytunnel?
Polycarbonate, glass and polytunnels all provide protected growing spaces, but differ in their glazing, insulation, durability and appearance. Compare the options below to find the right fit for your garden.
Polycarbonate sheet greenhouse
- Lightweight, impact-resistant glazing
- Twin-wall panels provide insulating air spaces
- Diffuses incoming light
- Choice of panel thicknesses
- Low-maintenance aluminium frame
- Suitable for a wide range of garden sizes
Classic glass pane
- Traditional greenhouse appearance
- Clear glazing provides high visibility
- Allows plenty of natural light inside
- Heavier and more fragile than polycarbonate
- A good choice if clarity and traditional styling are priorities
Polytunnel
- Flexible cover stretched over a supporting frame
- Creates a protected growing environment
- Typically offers a different construction and appearance to a rigid greenhouse
- Useful for larger growing areas
- An alternative where rigid polycarbonate or glass glazing isn't required
Which greenhouse material should you choose?
If you prioritise lightweight, impact-resistant glazing and insulating twin-wall panels, a polycarbonate greenhouse may be the right choice. Choose glass if you prefer a traditional appearance and clear glazing, or consider a polytunnel if you want a flexible covered growing structure.
Choose the right polycarbonate greenhouse style
The layout of your garden can be just as important as the size or glazing specification when choosing a greenhouse. Our polycarbonate range includes both freestanding and lean-to designs, giving you different ways to make use of the available space. A freestanding greenhouse gives you a self-contained growing area that can be positioned in a suitable open part of the garden, while a lean-to greenhouse is designed to sit alongside an existing wall.
Lean-to polycarbonate greenhouses
A lean-to polycarbonate greenhouse is designed to stand alongside an existing wall, making it a useful option where a full freestanding greenhouse is not the best fit. Its compact layout can work particularly well beside a house, garage or other suitable garden wall while still creating an enclosed growing area for plants, herbs and vegetables.
Freestanding polycarbonate greenhouses
Freestanding polycarbonate greenhouses offer flexibility when you have space for a separate growing structure in the garden. Our range includes a wide variety of footprints and specifications, from straightforward models with 6-8 mm twin-wall glazing through to higher-specification greenhouses with thicker panels, taller sidewalls and included foundation frames on selected models.
Our service
Polycarbonate glazing is a long-lasting and effective alternative to greenhouse glass. The sheets provide a host of benefits, which complement the strong frame made of aluminium. Available in a wide range of sizes, plastic greenhouses feature glazing sheets from 6 mm to 16 mm thick.
