Product Information

Full details

The PolyX 25mm Multiwall Polycarbonate Sheet is a high-specification glazing solution ideal for homeowners and professionals constructing conservatories, lean-tos, or high-performance roofing structures. It provides exceptional thermal insulation and structural durability while remaining lightweight for easier handling during installation. Please note that while the opal finish is excellent for light diffusion and privacy, it is designed for fixed glazing systems and requires proper edge sealing to maintain its lifespan.

Extended Product Information

FAQs

Can I use this for vertical windows?

While it can be used for privacy glazing, it is primarily engineered for roofing applications due to its thickness and thermal properties.

Which side should face the sun?

The side of the sheet featuring the protective UV-resistant layer must always face outward.

How do I clean the sheets?

Use a soft cloth with warm, soapy water. Avoid pressure washers and abrasive materials.

Is this sheet easy to cut to size?

Yes, it can be cut easily using a fine-toothed saw or a jigsaw, provided the sheet is well-supported during the process.

What is the expected lifespan?

The product has a life expectancy of at least ten years when installed and maintained correctly.

Troubleshooting

Condensation inside the sheet channels

Ensure that breather tape is applied to the bottom edge and that the drainage holes in the glazing bars are clear.

Sheet is expanding or buckling

Ensure you have left adequate expansion gaps in the glazing bars, as polycarbonate naturally expands with temperature changes.

Pros and Cons

Pros

  • Excellent thermal properties for energy efficiency
  • Lightweight construction reduces structural load
  • High impact resistance for long-term durability
  • Opal finish eliminates glare and provides privacy
  • Class 1 fire safety rating

Cons

  • Not suitable for curved applications
  • Requires specific compatible glazing bars
  • Opal finish reduces visibility compared to clear sheets

Setup, Compatibility & Care

For installation, ensure you are using a professional-grade self-supported glazing bar system to secure the sheets. Always use compatible EPDM rubber gaskets to allow for natural thermal expansion and contraction of the polycarbonate. To cut the sheet, use a fine-toothed circular saw or a jigsaw with a blade designed for plastics. Keep the flutes clean by sealing the top and bottom edges with breather tape, followed by an end closure profile to prevent dust and moisture buildup inside the channels. To clean the surface, use only mild soap and water; avoid abrasive pads or harsh chemical cleaners which can strip the protective UV coating.
