Additionally, polycarbonate is significantly more impact-resistant than traditional materials like glass, making it a safer option in areas prone to impacts or accidents. It can withstand high winds, hail, and accidental blows without shattering.

  • UV protection:

Twin wall polycarbonate sheets are commonly coated with a UV-resistant layer during manufacturing. This layer blocks the harmful ultraviolet rays from the sun. As a result, it prevents yellowing, brittleness, and degradation of the polycarbonate material over time. The UV protection prolongs the lifespan of the polycarbonate sheets, ensuring long-term performance and aesthetics.

  • Light transmission:

Despite being lightweight, twin wall polycarbonate allows significant light transmission. The clear and transparent nature of polycarbonate sheets ensures natural light penetrates indoor spaces. This helps reduce the reliance on artificial lighting during the day. The diffused light creates bright and welcoming internal environments. This feature is particularly important in areas prone to limited sunlight.

  • Easy to work with:

Twin wall polycarbonate is relatively easy to cut, drill, and install. It can be shaped and adjusted to fit specific requirements without the need for specialized tools or skills. The lightweight nature simplifies handling and placing during installation. The flexibility of polycarbonate sheets allows for custom designs and applications.

  • Fire resistance:

Some twin-wall polycarbonate sheets are engineered with fire-retardant properties, which inhibit the spread of flames. This enhances safety in case of fire accidents. These fire-resistant twin wall polycarbonates comply with fire safety regulations in commercial and residential buildings.
