Polycarbonate guide

What is Polycarbonate?

A lightweight, impact-resistant and recyclable glazing material for daylit buildings.

Clear polycarbonate resin granules

Lightweight

Multiwall polycarbonate sheet from Gallina India is a lightweight material that reduces building costs while meeting the structure's loading requirements.

Translucent

Transparency is a key feature of polycarbonate. Integrated into roofs, vertical walls and skylights, Gallina multiwall sheets and panels make the most of daylight, creating a comfortable interior with good thermal insulation. Panels can be tinted to modulate light transmission, optimise shading and reduce overheating, and coloured pigments achieve effects that satisfy demanding architectural requirements.

Versatile

We supply an extensive range of products for translucent roofs and walls, skylights, and fixed or operable insulated windows. Continuous research has produced a series of steel and aluminium accessories to complete the range. Our systems are designed for simple, safe installation and compliance with most building codes, and are tested and certified for fire rating, loading and thermal performance.

UV and hail resistant

Gallina multiwall polycarbonate is tested for hail impact. A high-performance UV layer is co-extruded on the exterior surface for optimal performance under prolonged exposure to strong sunlight, and products are third-party tested and certified for accelerated weathering.

Safe

Multiwall polycarbonate has particularly high impact strength. Our products meet the requirements and safety standards for translucent glazing in public and private work environments.

Environmentally friendly

Extruding multiwall polycarbonate uses very little energy and has a minimal environmental impact. Polycarbonate is an energy-efficient solution and is 100% recyclable at the end of its life.
