Polycarbonate Roofing for Industrial & Commercial Buildings

For most industrial buildings in India, 16 mm Multicell is the standard specification. It provides a U-value of 1.9 W/m²K, handles standard purlin spacing of 600–900 mm, and is certified to all applicable Indian and international load standards. For larger spans (1,000–1,200 mm between purlins), 20–25 mm or the X-Fix system is recommended.

Coxwell polycarbonate roofing carries a 10-year manufacturer's warranty against manufacturing defects, subject to standard terms. The UV protection is co-extruded into the panel surface — not coated on — which means it cannot peel or wash off.

It depends on the tint specification. Clear panels transmit both visible light and infrared heat — suitable for factories and carparks where heat gain is acceptable. For occupied spaces, Solar Ice or Ice tints reflect the infrared spectrum responsible for heat gain while maintaining daylight quality. For maximum heat control with premium performance, Prism is the Coxwell system specifically engineered for climate control.

Yes. Multicell and X-Fix panels are cold-bendable to a minimum radius of approximately 15× the panel thickness. For a 16 mm panel, the minimum cold-bend radius is approximately 2.4 m. Tighter radii require factory hot-forming. Vault and eye-shape profiles are among Coxwell's most common specifications — including 5,239 m² of vault roofing at Sarai Kale Khan Metro Interchange, Delhi.

Yes. Coxwell has delivered polycarbonate roofing to CPWD, PWD, AAI (Airports Authority of India), Indian Railways, NBCC, and multiple state PWDs. IS 14434 references and product documentation are available on request.

The minimum recommended pitch is 5° (approximately 1:12) for all Coxwell standing-seam systems. A 5° pitch ensures drainage and prevents ponding in the panel channels.

Polycarbonate (PC) has significantly higher impact resistance than fibreglass and UV co-extruded grades are designed for long-term weathering resistance. PVC sheets are cheaper but yellow within 3–5 years in Indian UV conditions and have poor impact resistance.
