Polycarbonate roofing sheets are a lightweight, impact-resistant alternative to glass. They’re commonly used to create covered outdoor areas, insulated roofing systems and weatherproof structures without the weight or fragility of traditional glazing.

At Omega Build, our range of polycarbonate roofing sheets is suited to everything from simple DIY projects through to professional installations, with options available in multiple thicknesses, finishes and sizes.

Standard Polycarbonate Roofing Rectangles are available:

• 4mm Twinwall Clear Polycarbonate.
• 10mm Twinwall Clear, Bronze and Opal Polycarbonate.
• 16mm Triplewall Clear, Bronze and Opal Polycarbonate.
• 25mm Fivewall Clear, Bronze, Opal, Bronze/Opal and Heatguard/Opal Polycarbonate.

What Are Polycarbonate Roofing Sheets Used For? 

Polycarbonate roofing sheets are used wherever you need a durable, translucent roofing solution that balances light, insulation and strength.

Our customers use our roofing sheets for applications including:

• Conservatories & extensions – allowing light in while improving thermal performance
• Lean-to roofs – ideal for side returns or garden structures
• Greenhouses – supporting plant growth with diffused light
• Walkways & commercial roofing – offering long-lasting, low-maintenance cover 

Because polycarbonate is far stronger than glass and significantly lighter, it’s especially useful where ease of installation and safety are important.

Why Choose Polycarbonate Over Glass?

Polycarbonate has become a go-to roofing material because it solves many of the common issues associated with glass:

• Doesn’t shatter – highly impact-resistant and safer to install
• Lightweight – easier to transport, handle and fit
• Thermally efficient – multiwall sheets help retain heat
• UV protected – prevents yellowing and extends lifespan
• Cost-effective – delivers performance without the price of glass systems

Thicker sheets (such as 16mm, 25mm or 35mm) provide greater insulation, making them ideal for year-round use in spaces like conservatories or enclosed outdoor areas.
