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.
Why use polycarbonate for greenhouse glazing?
The glazing of our polycarbonate greenhouses is made from twin-wall polycarbonate panels. These sturdy plastic panels are made up of two transparent sheets connected at even intervals, creating cells of trapped air with effective insulation properties.
Polycarbonate panels or sheets for greenhouses have the following characteristics:
Lightness and strength
High impact resistance
Good thermal insulation
Excellent light transmission
Long life
Twin-wall polycarbonate for greenhouses is therefore ideal for outdoor use in the garden. Polycarbonate sheets provide effective protection from rain, wind and snow. Another advantage of the double-walled polycarbonate greenhouse is that the greenhouse glazing is UV-resistant thanks to a protective UV film.
Our greenhouse is made entirely of polycarbonate and aluminium. The high quality frame made of aluminium holds the greenhouse panels in place, with no overlap between the glazing sheets.
Polycarbonate greenhouse vs glass greenhouse: a comparison
Glass is a traditional choice for greenhouse glazing, offering excellent clarity and longevity, but it tends to be heavier and more fragile compared to polycarbonate. Both materials have their merits, with glass being scratch-resistant and providing aesthetic appeal to your garden while polycarbonate offers practical advantages, being durable and exhibiting impact strength.
Polycarbonate sheet greenhouse
- Light & resistant material
- UV protection
- Anti-shattering sheets
- Cheaper to replace
Classic glass pane
- Heavier than plastic sheets
- Susceptible to impact
- Can cut if broken
- Costly to replace
Glass greenhouses also have plastic roofs
The strength, longevity and light transmission of our plastic panels are also used in the roof and gable panels of GFP greenhouses that are glazed with glass. As well as being an important safety consideration, plants appreciate the even distribution of light throughout the greenhouse.
Our polycarbonate greenhouse in different sizes
We offer our polycarbonate greenhouse in a wide range of sizes. Our smallest plastic greenhouses start from a 2.5 m² polycarbonate greenhouse. A small plastic greenhouse is an ideal alternative to a polytunnel for smaller plants, affording you easy access and durability. A walk-in garden greenhouse is a good option for gardeners who want to grow a wider range of plants.
Our polycarbonate greenhouse in different thicknesses
Our polycarbonate greenhouse in different thicknesses The polycarbonate greenhouse is fitted with panels of different thicknesses. The thickness of the greenhouse polycarbonate sheets plays a part in the choice of model: the thicker the sheet, the stronger and better insulated the polycarbonate greenhouse glazing is.
We offer polycarbonate sheets from 6 mm to 16 mm. The 6 mm and 8 mm polycarbonate greenhouses provide good protection and insulation at a good price. A model with a 10 mm polycarbonate sheet for a greenhouse offers even greater resistance and insulation for your plants. For optimum, safe, long-lasting protection, we recommend a greenhouse glazed with 16 mm polycarbonate sheet.
