Product Information

Full details

The PolyX 35mm Multiwall Polycarbonate Sheet is an ideal choice for contractors and DIY enthusiasts working on conservatory roofing or high-durability outdoor structures. It offers exceptional thermal efficiency and structural strength in a lightweight form, making it easier to handle than traditional glass. While it provides excellent light diffusion through its opal finish, users should note that the 35mm thickness requires specific compatible glazing bars to ensure a proper, weather-tight installation.

FAQs

Can I use this sheet for vertical walls?

Yes, it is suitable for vertical installations, though it is primarily designed for structural roofing applications.

Which side faces the sun?

The side with the UV-protective film must face outwards. This is clearly marked on the manufacturer's protective packaging.

What is the minimum life expectancy?

The product has a minimum life expectancy of ten years when installed according to the provided guidelines.

Is this material fire resistant?

Yes, the sheet carries a Class 1 fire rating, making it suitable for standard building regulation requirements.

How do I cut the 35mm sheet?

A fine-tooth circular saw or a jigsaw with a blade suitable for plastics works best. Ensure the sheet is supported to prevent vibration.

Troubleshooting

Condensation inside the flutes

Ensure that proper breather tape is applied to the bottom edges and the top is sealed with foil tape to prevent moisture ingress.

Sheet expansion or contraction sounds

Ensure you have left adequate expansion gaps within the glazing bars during installation to allow for thermal movement.

Surface appears cloudy or damaged

Verify the protective film was removed correctly and avoid using ammonia-based cleaners which react with polycarbonate.

Pros and Cons

Pros

  • Excellent thermal performance for all-season use
  • Lightweight construction simplifies handling and lifting
  • Opal finish effectively minimizes glare
  • High impact resistance compared to glass
  • Compliant with Class 1 fire safety standards

Cons

  • Requires specific glazing bar systems for best results
  • Opal tint reduces total light transmission compared to clear versions
  • Cutting 35mm thick sheets requires precision tools
  • Not suitable for applications requiring high-transparency views

Setup, Compatibility & Care

Installation requires a compatible self-supported glazing bar system to accommodate the 35mm thickness. Ensure that the UV-protected side of the sheet is facing outwards; this is typically indicated by a protective film on the top face.

Maintenance Tips:

  1. Use a mild soap and water solution with a soft sponge for routine cleaning.
  2. Avoid using abrasive cleaning agents or harsh chemicals that could scratch or degrade the surface.
  3. Regularly inspect the edges and joints to ensure no debris has accumulated that might impede thermal expansion or drainage.
  4. Ensure the open ends are sealed with appropriate breather tape to prevent moisture and algae build-up within the internal flutes.
