Hollow Multiwall Polycarbonate Sheet

Our Hollow Multiwall Polycarbonate Sheets are designed for projects that require daylighting together with improved thermal insulation. The internal wall structure reduces heat transfer compared with solid single-skin sheets, making this category suitable for greenhouses, enclosed rooflights, walls, covered walkways, and commercial building envelopes.
We offer hollow PC sheet options from 4 mm to 25 mm. The 4-12 mm range is suitable for lightweight roof, wall and greenhouse applications, while the 15-25 mm multiwall range is designed for projects with higher insulation requirements. Standard reference width is 2,100 mm, with cut-to-length supply available. Customer-provided catalogue data shows reference U-values from 3.9 to 1.8 W/m²·°C, depending on thickness and structure.
Available configurations include customised colour, light transmission, thickness and panel length. This category can be used for agricultural and commercial greenhouses, daylighting roofs, translucent walls, enclosed corridors, public canopies and energy-conscious industrial enclosures. We can support selection based on frame spacing, roof geometry, climate, insulation target, daylight requirement, and installation method.
