The Corotherm 25mm Clear Multiwall Polycarbonate Roofing Sheet is a premium glazing solution built for maximum strength, insulation and light clarity. Manufactured with a seven-wall internal structure, this 25mm multiwall sheet delivers exceptional thermal performance with a U-value of 1.6W/m²K, helping reduce energy costs and maintain indoor comfort year-round.
Constructed from durable polycarbonate, it is up to 200 times stronger than glass, offering reliable resistance against hailstones, accidental impacts and general wear. Unlike traditional glazing, it will not crack or shatter, making it a trusted choice for high-traffic or exposed areas.
Ideal for a wide range of home and garden projects, this sheet is commonly used for conservatories, canopies, lean-to roofs, carports, veranda covers, greenhouses, porches, and vertical glazing. The optically clear finish allows generous natural light to pass through while maintaining a clean, modern appearance.
Despite its thickness, the sheet remains lightweight and easy to handle, meaning it can be cut and installed on-site with basic tools. A minimum 10° roof pitch is required for proper water runoff, and it should be installed using low-modulus neutral cure sealant and butyl flashing tape for best results.
Offering low condensation risk, a self-cleaning surface, and a 10-year manufacturer’s guarantee, this sheet provides a long-lasting, low-maintenance solution for any glazed roofing application.
