Polycarbonate Greenhouses

Waltons polycarbonate greenhouses are designed to suit the needs of beginner and expert gardeners that are looking for a new space to grow their own vegetables, exotic fruits and flowers.

Polycarbonate is a fantastic material for greenhouses as it is 100% shatterproof and economically friendly. Polycarbonate also provides better insulation than glass as plastic retains heat resulting in a warmer greenhouse environment. Greenhouses with better heat retention perform much more effectively.

Our range of polycarbonate greenhouses are built to last and most of the polycarbonate greenhouses in the range are built with a robust aluminium frame. Polycarbonate greenhouses are also much easier to install than a glass greenhouses. The aluminium framing is also really light weight and easy to handle especially when putting it together. Any DIY novice should be able to put together one of our aluminium framed polycarbonate greenhouses with ease, all you need is a free day and a couple of friends and you'll have your brand new greenhouse up in no time.

To see some of our tips for installing a greenhouse check out our help and support section. Here at Waltons, we stock six ranges of Polycarbonate greenhouses. The ranges differ in style, size and quality.
