610mm x 450mm x 24mm Greenhouse Window (3mm Polycarbonate)

Virtually Unbreakable, Insulating & Built to Last

For maximum strength and long-term performance, our 3mm thick polycarbonate panel is the ultimate greenhouse glazing upgrade. This 610mm x 450mm x 24mm panel is a popular replacement size for Halls greenhouses and is 200 times stronger than glass. It is virtually unbreakable and highly resistant to impacts, storms, and harsh weather conditions.

Unlike standard glass, which can deteriorate over time, polycarbonate blocks 99% of harmful UV rays, protecting your plants while allowing even light diffusion to prevent hot spots and glare. Additionally, its insulating properties help maintain a stable greenhouse temperature, ensuring better plant growth throughout the year.

Replacing your greenhouse windows has never been easier - we deliver these panels straight to your door, saving you the hassle of searching for local suppliers or transporting fragile glass. If you need a different size or shape, we also offer custom-cut greenhouse windows tailored to your exact specifications.

For a seamless installation, check out our greenhouse window installation guide and get your new panel fitted in no time.

Good product as are the rectangular ones but this one is wrong size so can’t fit it. Thought I’d measured correctly.
