What sizes can you cut polycarbonate sheets to?

We can cut your polycarbonate sheet to any size up to 6m in length and 2.1m in width. Enter your exact dimensions using the calculator tool on the page.

How accurate is the cut?

Sheets are cut to within ±5mm tolerance and arrive clean, sealed, and ready to install.

Are sheets ready to install when delivered?

Yes. Each sheet is blown out to remove dust and debris, then sealed with breather and blanking tape before dispatch.

Do I need to seal the sheet ends myself?

No. We apply breather and blanking tape before dispatch. You’ll just need to fit closures or U profiles for a finished edge.

What thickness should I choose?

Choose 4–6mm for greenhouses and cold frames, 10mm for sheds and budget roofing, 16mm for lean-tos and carports, and 25–35mm for conservatories or all-year rooms.

What colours are available?

Clear, Opal, Bronze, Bronze/Opal, and Solarguard. Each offers different levels of light transmission and heat control.
