Polycarbonate Roofing Sheets for Domestic and Commercial Projects

Polycarbonate is a practical alternative to traditional glass roofing. It allows natural light into the space while remaining significantly lighter and highly resistant to impact. This makes it easier to handle and suitable for projects where strength, weather resistance and straightforward installation are important.

Our range covers small garden projects as well as larger domestic and commercial roofs. Different structures, thicknesses and finishes are available to provide the right balance of light transmission, insulation, rigidity and cost.

Types of Polycarbonate Roofing Sheets

Twinwall sheets are commonly used for lighter DIY roofs and sheltered structures. Multiwall sheets contain additional internal layers, increasing stiffness and insulation for conservatories, carports and larger spans. Corrugated sheets suit simple agricultural, garden and canopy applications, while solid polycarbonate provides a smooth clear appearance with exceptional impact resistance.

Why Choose Polycarbonate Roofing?

Polycarbonate combines high impact strength with low weight, helping make roof panels easier to move, cut and fit than glass. UV-protected roofing sheets are designed for long-term outdoor exposure and are available in clear, bronze, opal and other finishes to control brightness, privacy and heat build-up.

Clear sheets provide the highest light transmission, while bronze and opal options soften glare and can make covered areas more comfortable. Thicker multiwall products also create insulating air pockets within the sheet, helping improve thermal performance.

Popular Applications

Polycarbonate roofing sheets are suitable for conservatories, lean-to roofs, pergolas, patio covers, carports, entrance canopies, greenhouses, garden buildings, covered storage areas and commercial roof glazing.

Choosing the correct thickness and support spacing is important. A small pergola may only require a lightweight sheet, while a conservatory or wider roof span normally benefits from a thicker multiwall product with greater rigidity and insulation.
