Whether you’re repairing storm damage, building from scratch or upgrading from glass, these greenhouse-ready polycarbonate panels are designed to give your plants the protection and stability they need - all year round.

What These Panels Do for Your Plants

Polycarbonate helps to protect your plants from cold snaps, overheating and shattered glass - keeping conditions more consistent, so you get stronger growth, fewer losses and less stress managing temperature swings. 

It’s light enough to handle solo, strong enough to withstand knocks and designed to fit easily into most metal or timber greenhouse frames - without the worry of glass smashing.

Which Thickness Should You Choose?

What About Light Levels?

Will It Fit? Can Anyone Install It?

Yes - these sheets are light, easy to handle and simple to trim with basic tools. Ideal for DIYers and tradespeople alike. They work with most standard greenhouse frames and don’t need specialist skills to fit.

You’ll just need glazing bars, end caps (and breather tape for multiwall panels to prevent condensation inside the flutes). Screws or clips secure them in place and flashings or trims can be added if needed.

Want to skip the cutting? Some of our polycarbonate sheets are available pre-cut to size.
