Multiwall Polycarbonate Sheet
Rigid, cellular polycarbonate panels designed to provide effective thermal insulation while allowing high levels of natural daylight. The multi-cell structure reduces heat transfer and improves energy efficiency, making these sheets suitable for applications requiring both light transmission and thermal performance.

Frequently asked Question
Multiwall polycarbonate sheets are rigid thermoplastic panels with a cellular structure that provides light transmission along with improved thermal insulation.
The internal air chambers reduce heat transfer, improving thermal performance compared to solid sheets of similar thickness.
Yes, they are commonly used in skylights, roof lights, and translucent roofing systems in industrial and commercial buildings.
Yes, they provide diffused natural light while reducing glare compared to clear glazing materials.
Yes, they are typically manufactured with UV-protective layers to resist yellowing and surface degradation.
Polycarbonate has high impact resistance, making multiwall sheets suitable for areas prone to hail and debris impact.
Yes, they are significantly lighter than glass, reducing structural load on the building.
Yes, within manufacturer-specified bending radius limits, they can be curved for architectural applications.
Proper sealing of sheet ends and correct orientation of flutes are essential to prevent moisture ingress and condensation buildup.
Thickness, light transmission requirements, insulation performance, UV protection, load conditions, and application type should be evaluated.
