About Our Polycarbonate Greenhouse Range
Our polycarbonate range tends to be with an aluminium frame, but we also stock wooden greenhouses here.
Why choose polycarbonate for your glazing?
Polycarbonate greenhouses are sturdy affairs, excellent for putting up with the rough and tumble realities of family gardens, flying footballs, and even attempted vandalism. They are sometimes known as perspex greenhouses.
Greenhouse Brands & Quality
Our wide selection of aluminium and polycarbonate greenhouses include designs from Halls, Eden, and Elite. Offered at affordable prices, these high-quality greenhouses will last for years and give excellent value for the money. There are cheaper alternatives out there, but the quick breakdown and failure of cheaper materials and construction mean early replacements and a loss of any perceived value the lower price might falsely promise. We only sell greenhouses that we would be confident in using ourselves, so you can benefit from our expertise and experience.
Large Sized Perspex Greenhouses
If you dream of a big greenhouse – or the abundant crops that would need one – we offer the 6x10 Halls Popular, each ten feet wide and fitted with twin wall 6mm polycarbonate glazing (better than the thinner 4mm versions). Still not enough? The 12x8 Elite Classique comes in at a whopping twelve feet across and is constructed with the same high-quality materials and glazing.
Each of these models can also be fitted with an additional set of double doors at the far end of the structure, so you can enter and exit from either end, or even place the greenhouse in an area where a through passage is required.
Strong Polycarbonate Glazing
Polycarbonate Greenhouse glazing is available in a twin-wall design, featuring 6mm thicknesses, which creates an insulating cavity between the panes, just like double glazing in a home.
The durability of these greenhouses is ideal for growing tomatoes, vegetables, herbs, and plants in your back garden or allotment.
Polycarbonate vs Toughened Glass
Glass greenhouses are more traditional in appearance, and the glass panels are completely transparent, making them more visually appealing. The toughened glass granulates when it breaks, which makes it safer than horticultural glass.
Polycarbonate glazing is not 100% transparent, so it's not as visually appealing as glass. However, it is the safest glazing you can choose, as the polycarbonate sheets won't shatter into pieces like glass.

John, 10/06/2020 Reviewed the 4x8 Elite Compact Aluminium Finish
"Excellent service from SWG, advised of delivery date and the greenhouse arrived a day earlier. Although I am a keen DIYer, the instructions sometimes were a bit of a challenge, however my wife was on hand to help! Also good support from Elite as needed. On my own it took about 18 hours in total to complete the build and it was easy to secure to my ready made base. Some areas of the instructions could have been a bit more explanatory (e.g Highlighting when extra bolts need to be inserted would have helped), but good when you figure it out. Only criticism is the door handles, did not fit them, will look for something locally a bit more friendly."
Nigel, 26/12/2017 Reviewed the 5x8 Elite Streamline Aluminium Finish
"Excellent phone service from both SW Greenhouses and Elite, delivery on time. Erection not for the faint hearted as much of the instrictions were vague, maybe more illustrations could help. The quality of the mouldings and accuracy of the fittings are superb resulting in a quality greenhouse. Fitting large panel toughened glass difficult until I slackened off most nuts. I Would recommend this greenhouse. Nigel. Cirencester"
