Multi-wall polycarbonate is a lightweight and extremely durable building material made of polycarbonate resin, whose unique structure provides excellent thermal insulation. Its main advantages include high impact and weather resistance (from -40°C to +120°C), UV protection, low weight that doesn't burden the structure, and high light transmission of up to 84%.

The panels should be installed with channels facing the direction of water flow, which prevents moisture from accumulating inside the chambers. It's important to maintain expansion gaps, allowing for thermal expansion of the material, and to properly secure the ends of the panels with tape: solid at the top and vapor-permeable at the bottom. The UV-filtering side (marked on the protective film) must always face outward.

Solid polycarbonate is a modern, safe alternative to glass, being significantly lighter and much more resistant to breakage. Unlike glass, this material does not crumble upon impact, which increases safety, and its processing (cutting, drilling) is much easier and does not require specialized tools.

Sources offer sheets in clear, smoked (brown), graphite, and opal (milky). The sheets are available in standard sheets (e.g., 2050x3050 mm), but it is also possible to order cut-to-size sheets.

This material is widely used in construction, agriculture, and industry. It is most often used for greenhouses, terrace roofs, carports, skylights, as well as infill for balustrades and partitions.

For terrace roofs, 10 mm or 16 mm thick panels are most often recommended, as they provide optimal rigidity. The color choice depends on your needs: clear provides maximum illumination, while smoked (brown), opal (milky), or graphite versions reduce heat gain and protect against glare.

Thanks to its transparency and enormous mechanical strength (comparable to aluminum), solid polycarbonate is used as a safe infill for windows and doors, acoustic screens, machine guards, and in bus shelters and walkway structures. It is also used for aesthetic terrace roofing, where a glass-like appearance is required.

Yes, solid polycarbonate sheets available from sources have a UV protective layer (often double-sided, labeled 2UV), which protects the material from yellowing and loss of mechanical properties. This ensures they maintain their aesthetic appearance and durability for many years, even with constant exposure to sunlight.
