Polycarbonate (PC) is ideal for hot weather and is one of the best-performing transparent plastics in terms of heat resistance.

Key Advantages: This material typically has a glass transition temperature of around 140°C-150°C. This means that even under intense summer heat (even inside cars or in greenhouses where temperatures exceed 80°C), it maintains extremely high dimensional stability and will not soften, deform, or fail structurally.

Crucial Performance:

Impact Resistance: It retains excellent toughness even after heating and will not become brittle at high temperatures like ordinary plastics.

UV Protection: High-quality PC sheets usually have a UV coating that blocks 99% of UV rays, protecting people and furniture from radiation damage.

Low Thermal Conductivity: While not as insulating as wood, its thermal conductivity is much lower than glass, effectively slowing heat penetration.

It is essential to leave sufficient expansion joints during installation. Although heat-resistant, its coefficient of thermal expansion is relatively high. If it is too tightly secured, the sheet may develop ripples or cracks due to thermal expansion in extremely hot weather.
