A · The briefCoxwell, established 1993. Polycarbonate roofing, façade and skylight systems.

We make the panels that let daylight through — without the heat, glare, or ageing of glass. Specified for India's largest atriums, stadiums and airports.

B · What we make better

Four reasons project teams keep specifying Coxwell.

A polycarbonate system is not a commodity. Every roof, façade, and skylight is a different load, a different climate zone, a different installation team. We engineer for all of them.

Daylight, designed

Up to 89% visible light transmission. Diffuse illumination up to 70% — glare-free, even light distribution with no harsh shadows or hotspots. Optional Antiglare/Softlite finish available across the range.

Built to outlast

UV protection co-extruded on both sides — not coated on afterwards, so it cannot peel or wash off. Designed for durable long-term outdoor performance.

Sustainably specified

Coxwell operates under ISO 9001 and ISO 14001 certified management systems. Product documentation available to support project-level green-building submissions. All panels are recyclable at end of life.

Engineered to fit

Custom widths, profiles, and colours. 6 mm to 40 mm thick; widths from 500 mm to 2,100 mm; lengths up to 12 m. Dry-fit installation on most systems — no wet seals, no specialist tools. One plant. One standard. From a residential carport to 18,000 m².

C · Products

Seven products.

Innovative panels (Prism, Vivid, Snapwall) bring climate-control, louver, and click-lock technologies. Traditional panels (Multicell, X-Fix, Coxwell Static, Coxwell Twinwall) are the workhorse range.
