25mm Clear Polycarbonate Roofing Sheets

Our PolycarbonateX 25mm Clear Multiwall Polycarbonate Roofing Sheets  are designed for projects where insulation, thermal performance and maximum natural daylight are the highest priorities. Manufactured from high-quality multiwall polycarbonate, these roofing sheets are ideal for conservatories, garden rooms, premium pergolas, verandas and year-round outdoor living spaces.

The clear finish allows maximum light transmission while the 25mm multiwall construction helps improve insulation, reduce heat loss and minimise noise from rainfall. This makes 25mm polycarbonate a popular choice for homeowners looking to create bright, comfortable and usable outdoor spaces throughout the year.

Compared to thinner roofing sheets, 25mm polycarbonate provides enhanced rigidity, improved thermal performance and excellent weather resistance, making it suitable for both domestic and commercial applications.
