Polycarbonate Hollow Sheets

Polycarbonate hollow sheets—commonly known as multiwall polycarbonate sheets—are lightweight, durable, and thermally insulating materials made with multiple layers and air pockets between them. They are ideal for applications requiring strength, light transmission, and insulation.

Key Features of Polycarbonate Hollow Sheets:

Feature Description
Structure Typically twin-wall, triple-wall, or more complex multiwall layers with air gaps in between.
Light Transmission High (up to 80%) depending on sheet thickness and color.
Thermal Insulation Air pockets reduce heat transfer, making them energy efficient.
Impact Resistance Extremely strong—up to 200 times stronger than glass.
UV Protection Often co-extruded with a UV-protective layer for outdoor durability.
Fire Resistance Self-extinguishing and compliant with many fire safety standards.
Lightweight Easy to handle and install, even in large sheets.
