Replacing Greenhouse Glass with 4mm Polycarbonate Panels

4mm greenhouse replacement polycarbonate panelWhen Mr Moody decided to upgrade his aluminium greenhouse, he chose to replace his original greenhouse glass with high-quality Marlon polycarbonate 4mm panels — a durable and increasingly popular alternative for modern gardeners.

Instead of reinstalling traditional glass, he ordered a 5-pack of our 4mm Clear Greenhouse Polycarbonate Sheet – 610mm Wide x 1220mm Long. These sheets are specifically designed as replacement greenhouse polycarbonate panels, making them ideal for standard aluminium greenhouse frames.

Why Switch from Greenhouse Glass to Polycarbonate 4mm?

More greenhouse owners are moving away from fragile greenhouse glass and upgrading to greenhouse glazing 4mm polycarbonate panels because they offer:

  • Excellent light transmission for strong, healthy plant growth
  • Much greater impact resistance than glass
  • Lightweight and easier handling during installation
  • Standard 610mm (61cm) width to fit most aluminium greenhouse frames

Mr Moody found the 61cm width to be a perfect fit for his existing structure, making the installation simple and hassle-free.

“I ordered 4mm polycarbonate in a 5 pack and very happy. Was packaged well and delivered quickly within specified time frame. The product is good quality (can’t comment on how long it’ll last as only just up) and the I guess standard 61cm fit my greenhouse well. Thanks.”
