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
Co-extruded UV protective layer ensures long-term resistance to weathering, yellowing, and hail damage. 10-year warranty included.
High clarity with up to 82% light transmission for clear sheets. Provides abundant natural daylight 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 — 200 times stronger than glass and 8 times lighter. Ideal for areas prone to extreme weather or vandalism.
Superior thermal insulation translates directly into lower energy consumption, reducing both environmental impact and operational costs.
Suitable for flat and curved installations. Easy to cut, drill and cold-bend on site. Wide range of colors and thicknesses for any project.

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.
Anti-dust tape for the bottom edge and breather tape for the top edge. Essential for long-term clarity and performance of the sheets.
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.
