Lightweight impact resistant racing windows

Step into the future of motorsport glazing with polycarbonate windows—where strength, safety, and performance come together on the track.

Offering more than 200 times the impact resistance of glass and around 30 times that of acrylic, polycarbonate is the smart choice for motorsport. It stands up to heat, improves insulation, and provides superior UV protection—all in a much lighter package than traditional glass, making installation and modifications easier and more efficient.

Polycarbonate isn’t just for racing, either. Its strength and reliability mean it’s used in heavy machinery, protective gear, and other demanding environments worldwide.

Whether you’re a competitive racer or a passionate enthusiast, polycarbonate windows are a proven upgrade for safety, performance, and ease of use.

Why RacePlastics Polycarbonate Windows?

Each of our polycarbonate windows is carefully made to order by our experienced UK team. Designed for motorsport, they offer lightweight performance, high strength, and maximum safety. Unlike Perspex or other acrylic alternatives, polycarbonate is shatterproof and significantly stronger than glass—ideal for competitive driving.

Our standard windows are 4mm thick to meet Motorsport UK regulations. For greater durability, we also offer 5mm FIA-compliant versions and hard-coated options for added scratch resistance.

Choose from clear, bronze, or grey finishes to suit your car’s style. You can also add sliding windows to one or both front doors if preferred.

With Race Plastics, you get precision-built motorsport glazing with proven strength, smart customisation, and track-ready reliability.
