Greenhouse Glazing 4mm Polycarbonate 1220mm x 610mm (4' x 2') pk10 CLEAR

Greenhouse Glazing 4mm Polycarbonate

These premium clear 4mm polycarbonate sheets are engineered to provide the ideal balance of strength, clarity, and practicality for greenhouse glazing. Each sheet measures 1220mm x 610mm (4' x 2'), and they are supplied in packs of 10, making them perfect for full greenhouse refits or routine maintenance.

Their multiwall cell structure diffuses light beautifully while still allowing excellent light penetration, promoting healthy plant growth. The ribbed design increases rigidity, giving each sheet superior impact resistance compared to traditional glass — meaning less risk of breakage from weather, debris or accidental knocks.

Lightweight and extremely easy to work with, these sheets can be cut and installed with minimal tools, making them a favourite for DIY gardeners and greenhouse owners looking for a long‑lasting, low‑maintenance solution.
