25mm Opal Heat Guard Multiwall Polycarbonate Sheet
Our 25mm Opal Heatguard Polycarbonate Multiwall Sheet combines coextruded UV protection, a heat-reflective silver outer layer and a light-diffusing opal interior to reduce solar heat gain by up to 50% while providing natural, softened daylight. Ideal for sunrooms, conservatories, and rooflights, this sheet keeps spaces cooler, especially in sunny, south-facing areas. At night, the opal interior reflects artificial light, creating a ceiling-like effect.
-
UV1 Protection: UV resistant on one side, effectively blocking harmful UV radiation and preventing yellowing.
-
Sheet(s) ends can be pre-taped with aluminium and anti-dust tape. The aluminium tape is placed at the top of the sheet and the anti-dust at the bottom of the sheet.

Information
Our 25mm multiwall polycarbonate sheets are Class 1 Fire Rating BS476/7.
Twinwall and Multiwall polycarbonate sheets are UV-protected, but only on one side! Look for the protective film with writing on it — this is the UV-protected side and should face the sun. The other side has no UV coating and should face away.
Opal Heatguard Polycarbonate Multiwall sheets are expertly designed with dual-layer color combinations to minimize heat build-up and solar glare while allowing softly diffused, natural daylight to fill your space. These sheets feature an innovative heat-controlling silver outer layer that reduces solar heat gain by up to 50%, complemented by a light-diffusing opal interior layer. Ideal for applications like sunrooms, conservatories, and roof lights, this material is perfect for creating a comfortable, well-lit environment. Specifically crafted for sunny, south-facing spaces, the Heatguard Multiwall Polycarbonate reflects and repels heat, keeping interiors cooler even in peak sunlight. The opal interior enhances daylight while reflecting artificial light at night, producing a soft, ceiling-like effect.
Pre-taping Service: Sheets come with aluminum and anti-dust tape applied to the ends of the sheet to prevent dirt and debris from entering the flutes. If you don't want taping, please specify at purchase. During preparation, a 10mm strip of protective film is removed, leaving a visible score line; this is standard practice and does not impact quality.
The open ends of the sheets need to be sealed with sheet closures.
We cannot guarantee where the blade lands when cutting the sheets, so it is not possible to ensure hard edges on all panels.
Please store and lay this material flat in a cool, dry place prior to installation.
