Multiwall Sheets

Devraj Roofing lightweight cellular Polycarbonate multiwall sheets offers optimum impact strength and superior thermal insulation. Its exceptional light transmission makes Devraj Roofing the perfect choice for diverse roofing, wall cladding, and glazing applications.

These are a favorite with interior decorators and marketers, as Devraj Roofing solid polycarbonate sheet delivers a unique appearance and value addition to their designs.

We offers a unique combination of material properties that makes it superior to other thermoplastic material or glass, making it the ideal product for roofing, glazing and fabrication.

Polycarbonate Sheets are co-extruded with high-density ultraviolet rays in order to provide excellent resistance to colour and surface degradation. They offer a combination of properties such as high transparency, high impact and fracture resistance, high heat resistance, good dimensional stability and good electrical insulation property.
