Polycarbonate multiwall sheets with UV protection, available in thickness from 4mm to 20mm.
Our multiwall polycarbonate sheets feature a unique multi-layer structure that provides exceptional thermal insulation while maintaining excellent light transmission. The hollow chamber design creates air pockets that significantly reduce heat transfer, making them ideal for energy-efficient building solutions.
All sheets come with co-extruded UV protective layer on the external surface, ensuring long-term resistance to weathering and yellowing. The UV protection guarantees a 10-year warranty against yellowing and loss of light transmission.
Available in twin-wall (2-wall), triple-wall (3-wall), five-wall, and seven-wall configurations to meet various thermal insulation and structural requirements. Custom lengths up to 12 meters available on request.
Why choose our multiwall polycarbonate sheets
Surface UV protective layer ensures long-term resistance to sun rays and material yellowing. The material comes with a 10-year warranty.
High clarity with up to 82% light transmission for clear sheets. Provides a high level of natural light while filtering harmful UV rays.
Multi-layer chamber structure with U-values as low as 1.2 W/m²K. Significantly reduces heating and cooling costs for energy-efficient buildings.
Virtually unbreakable - 250 times stronger than glass of equivalent thickness and 8 times lighter. Ideal for areas with extreme weather conditions or locations with a high risk of vandalism.
Superior thermal insulation directly affects lower energy consumption, thus reducing the negative environmental impact.
Suitable for flat and curved installations. Easy to cut, drill and cold-bend on site. Wide range of colors and thicknesses for any project.

Our multiwall sheets are available in a range of colors and tints
If you want a color not in our standard range, provide a material sample and we will produce a custom masterbatch. Please note production time will be longer than the usual 10–14 days.
Professional installation solutions for optimal performance
Aluminium and polycarbonate H-profiles for joining sheets side by side. Available for all thicknesses from 4mm to 20mm.
End closure profiles that seal the open ends of multiwall sheets, preventing moisture and dust ingress into the chambers.
Special thermal washers with UV-resistant gaskets ensure watertight fixing points while allowing for thermal expansion.
Choosing the right thickness depends on snow load, wind load, and span dimensions
Small greenhouses, interior partitions, decorative elements. Spans up to 700mm.
Standard roofing, carports, canopies, medium greenhouses. Spans up to 1050mm.
High-performance thermal insulation, large span projects, commercial greenhouses. Best U-values.
