A Multiwall Polycarbonate Sheet is a lightweight, durable, and high-performance glazing panel made from layers of polycarbonate (a strong thermoplastic) with multiple hollow walls or chambers between them. These internal air pockets give the sheet excellent thermal insulation and strength while keeping weight low — a key feature that sets it apart from single-layer solid plastic or glass panels.
📌 What It Is
Material: Polycarbonate plastic formed into a sheet with two or more layers separated by vertical ribs.
Structure: Hollow multi-wall design (twinwall, triplewall, fivewall, etc.) improves strength and insulation.
Weight: Much lighter than glass despite being very strong.
🌟 Key Properties & Benefits
High Impact & Weather Resistance: Very tough — far stronger than glass and resistant to cracking or shattering.
Thermal Insulation: Air gaps reduce heat transfer, helping keep interiors cooler in summer and warmer in winter.
UV Protection: Often has a co-extruded UV layer that blocks harmful UV rays and prevents yellowing.
Light Transmission: Allows natural light in while diffusing glare, improving daylighting inside spaces.
Lightweight & Easy to Install: Easier to handle, transport, cut, and install than glass or solid plastics.
Fire and Sound Performance: Can meet fire safety standards and reduce noise due to the multi-layer structure.
