25mm Opal Five-Wall Polycarbonate Sheets

Our 25mm Opal Polycarbonate Sheets provide outstanding thermal performance, excellent light diffusion and exceptional strength. The five-wall construction delivers significantly improved insulation compared with thinner polycarbonate sheets, while the opal finish creates a bright and comfortable environment by softening natural sunlight.

Ideal for conservatories, garden rooms, commercial buildings and premium roofing projects, 25mm opal polycarbonate offers a high-performance glazing solution that combines durability, energy efficiency and attractive aesthetics.

The opal finish diffuses sunlight evenly across the covered area, reducing glare and creating a softer, more comfortable level of natural illumination. Unlike clear sheets, which allow direct sunlight through, opal polycarbonate helps minimise bright spots and excessive solar gain.

This makes it particularly suitable for spaces that are regularly occupied throughout the year.

Five-Wall Construction

The advanced five-wall structure contains multiple insulating air chambers that help improve energy efficiency while maintaining excellent structural strength.

U-Value: Approximately 1.6 W/m²K

Superior Thermal Performance

25mm polycarbonate sheets are often selected for projects where insulation is a priority. The multiwall construction helps reduce heat loss during colder months while also contributing to a more comfortable environment during warmer weather.

This makes them an excellent choice for year-round use areas such as conservatories and garden rooms.
