Product Information

Full details

The PolyX 25mm Multiwall Polycarbonate Sheet is an ideal solution for contractors and homeowners looking to build or refurbish conservatory roofs, offering a superior balance of thermal insulation and structural durability. This high-specification material provides excellent light diffusion and impact resistance while remaining lightweight for easier handling; however, it requires precise installation using compatible glazing bars to ensure optimal weatherproofing and long-term performance.

FAQs

Which side faces the sun?

Always install the side with the printed protective film facing upward/outward, as this is the side treated for UV protection.

Can I use these sheets for vertical windows?

While highly durable, these are specifically engineered for roofing and overhead applications. Check local building codes for vertical glazing requirements.

Do I need special tools to cut them?

A standard power saw with a fine-toothed blade designed for plastics is generally sufficient to achieve a clean cut.

How do I clean the sheets?

Use a soft sponge or cloth with warm water and a mild detergent. Avoid harsh chemicals or abrasive scrubbing pads which can damage the finish.

What is the expected lifespan?

The material is designed for at least ten years of service when installed and maintained correctly.

Is this sheet clear or opaque?

This is an Opal finish, which is translucent; it diffuses light to reduce glare but does not allow clear visibility through the sheet.

Troubleshooting

Moisture buildup inside the flutes

Ensure the edges are correctly sealed with appropriate breather tape and that the bottom end is not fully sealed to allow for drainage.

Sheet expansion causing creaking noises

Check that the glazing bars allow for thermal expansion and that the fixings are not overtightened.

Pros and Cons

Pros

  • Excellent thermal performance for energy efficiency
  • Lightweight design simplifies manual handling during installation
  • High impact resistance compared to standard glass
  • Class 1 fire safety rating for added protection
  • Long 10-year lifespan for reduced replacement frequency

Cons

  • Requires specific self-supported glazing bars for proper installation
  • Not suitable for applications requiring high-transparency glass views
  • Cutting requires proper tools to avoid damaging the multiwall flutes

Setup, Compatibility & Care

To ensure the longevity of your PolyX sheets, always install them with the UV-protected side facing outward, as indicated on the protective film. Proper installation necessitates the use of compatible self-supported glazing bar systems, which provide the necessary expansion room for the material while maintaining a watertight seal. When cutting the sheets, use a fine-toothed saw to prevent splintering of the multiwall flutes. Keep the edges sealed with breathable aluminum tape to prevent condensation and debris from entering the internal chambers. For maintenance, a periodic wash with mild soap and water is sufficient to keep the surface clear and prevent abrasive damage.
