Frequently Asked Questions
How thick should I choose for my polycarbonate sheet?
2mm and 3mm are suitable for light glazing, picture frames and craft projects. 4mm–6mm suits greenhouse panels, shed windows, machine guards and general glazing. 8mm–10mm is used for security screens and heavy-duty industrial applications. If in doubt, 4mm is the most versatile all-round choice.
What is the difference between polycarbonate and acrylic?
Polycarbonate is approximately 250 times stronger than glass and 30 times stronger than acrylic — nearly unbreakable. Acrylic is clearer (92% vs 90% light transmission) and more scratch resistant. Choose polycarbonate for strength and impact resistance; acrylic for optical clarity or display use.
Can polycarbonate sheet be drilled?
Yes. Standard HSS or wood drill bits work well. Use moderate speed, light pressure, and a scrap board underneath to prevent blow-out. We can drill holes for you — select Drilled Holes in the Optional Extras above.
Can polycarbonate be cut with standard tools?
Yes. A circular saw or jigsaw with a fine-tooth blade gives clean cuts. Score-and-snap works for 2mm–3mm sheets. Leave the protective film on during cutting to prevent scratches. Note: laser cutting produces toxic fumes and burns edges — not recommended.
Is polycarbonate UV resistant and suitable for outdoor use?
Yes. Our polycarbonate is UV-stabilised and suitable for outdoor use including greenhouse panels, shed windows, canopies, roofing and fencing. UV protection prevents yellowing and degradation over time.
Does polycarbonate expand with temperature changes?
Yes — approximately 0.07mm per °C per 100mm length. A 1000mm sheet can move ±1.2mm per 10°C. Always allow clearance in fixings and frames to accommodate thermal movement.
What is the minimum order for cut-to-size?
The minimum order value for cut-to-size sheets is £60.00 (inc. VAT). Minimum dimension is 100mm × 100mm. No minimum applies to standard pre-cut variants.
How is the sheet delivered?
Supplied with protective film on both sides. Packed with foam, cardboard and corner protection. Larger sheets are palletised. Same-day dispatch before 2pm Mon–Fri, delivered in 1–3 working days.
Description
Clear polycarbonate sheet is the go-to clear plastic when glass or acrylic would crack. Choose a ready-cut panel from 250 x 250mm up to a full 3050 x 2050mm sheet, in 2mm to 12mm thickness, for glazing, machine guards, protective screens, displays and DIY projects.

Why polycarbonate?
- Very high impact strength – far tougher than glass or acrylic, so it is used where breakage is a safety or security risk.
- Clear and lightweight – about half the weight of glass of the same thickness.
- Easy to work – thinner gauges can be cut, drilled and cold-curved on site.
Typical applications
- Machine guards and safety screens in workshops and factories
- Replacement glazing for sheds, outbuildings, greenhouses and doors
- Counter screens, sneeze guards and security glazing
- Retail displays, covers and protective panels
- Rooflight and canopy panels (check UV protection requirements for long-term outdoor use)
Cutting, drilling and fixing
- 2–3mm can be scored and snapped or cut with fine-tooth tools; thicker sheet is best cut with a fine-tooth circular saw or jigsaw, supporting the sheet close to the cut.
- Drill with a sharp HSS bit at low speed; keep holes at least 2x the hole diameter from the edge.
- Polycarbonate expands with heat – oversize fixing holes and do not over-tighten screws. Use washers or glazing tape rather than rigid clamping.
- Leave the protective film on until fitting; clean with mild soapy water only (no solvents).
