The PolyX 35mm Multiwall Polycarbonate Sheet is a high-performance roofing material ideal for DIY enthusiasts and trade professionals working on conservatory roofs or large-scale glazing projects. Its primary benefit is a superior strength-to-weight ratio that provides excellent thermal insulation and structural integrity without the heavy burden of glass, though installers must ensure compatibility with appropriate glazing bar systems to maintain a watertight seal.

Always face the side protected by the UV-resistant film (indicated on the packaging or protective masking) toward the outside.
While intended primarily for roofing, they can be used vertically if supported correctly, though they are specifically engineered for the structural requirements of roof pitches.
Clean with lukewarm water, a mild detergent, and a soft cloth. Never use abrasive sponges or window cleaning chemicals.
Polycarbonate generally has high fire resistance ratings, but you should consult the specific technical data sheet for your local building regulation requirements.
The flutes provide structural rigidity and act as air pockets to enhance the thermal insulation properties of the sheet.
No, you should not paint or apply additional coatings to the sheets, as this may react with the polycarbonate and damage the material or void its integrity.
Ensure the bottom edge is sealed with correct breather tape and the top edge is fully sealed to prevent moisture entry while allowing ventilation.
Use a fine-toothed circular saw or a dedicated polycarbonate blade to minimize vibration and splintering.
Ensure that the sheets are not fitted too tightly in the glazing bars, allowing for natural thermal expansion and contraction.
Installation requires a self-supported glazing bar system to ensure structural support across the width of the sheets. Always ensure the side marked with the UV-protective film is facing toward the exterior, as improper orientation will lead to premature material degradation. When cleaning, use a mild soap solution and a soft cloth or sponge; avoid harsh abrasive cleaners or scrapers, which can damage the Solarguard coating. Regularly inspect the edge seals and glazing bars to ensure they remain clear of debris and that the moisture-permeable tape at the bottom edge is intact.
