Polycarbonate skylight roofs – Lightweight and energy-efficient
Polycarbonate panels outperform other plastic roofing materials in terms of strength, stability, and durability, making them the ideal choice for skylight roofs and covers in buildings. They offer UV resistance, waterproofing capabilities, and a lightweight design, resulting in lower transportation and handling costs. Polycarbonate’s exceptional thermal insulation performance plays a crucial role in daylight architecture, providing warmth during winter and coolness during summer. Polycarbonate daylighting contributes significantly to energy conservation and sustainable development.
