Features of Double Wall Polycarbonate Sheets

Superior light transmission: Twinwall polycarbonate greenhouse panels provide up to 80% light transmission and diffuse sunlight evenly, helping support healthy plant growth.

Excellent thermal insulation: The double-wall hollow structure offers better thermal insulation than glass, helping reduce heat loss and improve greenhouse energy efficiency.

High impact resistance: Polycarbonate panels resist hail, snow, debris and impact, making them suitable for agricultural, construction and outdoor roofing applications.

Weather and UV resistance: A co-extruded UV layer helps prevent yellowing and aging, supporting long-term outdoor use in greenhouses, skylights and canopies.

Lightweight and easy to install: Twinwall PC sheet is much lighter than glass and can be cut and installed more easily, reducing roof load, labor and transportation cost.

Custom options: HSQY can supply different thicknesses, colors, widths and sheet sizes for greenhouse, roofing, skylight, signage and storm panel projects.
