Laminated windshields and toughened vehicle glass for makers, body builders and fleets.
CLSG started in 1987 making laminated OEM windshields, and vehicle glass still runs through the plant every day for vehicle makers, coach builders and state transport fleets. Unlike most auto glass suppliers, we laminate in our own plant rather than buying in and reselling, so one conversation covers the drawing, approvals and dispatch.

Armoured Vehicle Glass
A laminated windshield is two layers of glass bonded to a PVB interlayer. When a stone hits, the glass cracks but sticks to the PVB, so the driver keeps a screen in front. The same principle sits behind our REAL SAFE Laminated Glass for buildings.
Side and rear windows are often toughened, the glass the trade calls car tempered glass. It's heat treated so that if it breaks, it falls into small blunt pieces instead of long shards. We make it alongside our laminated windshields and quote both by model.
Where each one goes on a vehicle comes down to what should happen when it breaks.
| Point | Laminated | Toughened |
|---|---|---|
| Build | Two glass layers + PVB | One heat-treated pane |
| When struck | Cracks, stays in one piece | Breaks into small blunt pieces |
| Holds together when broken | Yes | No |
| Usual place | Windshields | Side and rear windows, cabins |
| Can be made bullet resistant | Yes, with more plies | No |
Customers include Tata and Volvo-Eicher, bus body builders such as JCBL, Azad, Sutlej and Paras Motors, and fleets like Delhi Transport Corporation and Haryana Roadways. Read About CLSG for the full list of certificates.
Whether you build buses, run a truck fleet or source glass for a new body, the same few details decide how fast a quote comes back and how well the glass fits. Settle them first and we can price the laminated windshield, side glass and back glass in one go.
None of this is a hurdle. A photo of the old glass and the model name is enough to start, and our team fills any gaps on a call.

A laminated windshield is two layers of glass bonded to a PVB interlayer, so it cracks but stays in one piece. Car tempered glass, also called toughened glass, is a single heat-treated pane that breaks into small blunt pieces. Windshields are laminated; many side and rear windows are toughened.
ARAI Pune and CIRT Pune approvals, plus e-certification from UTAC, France and RDW, Netherlands for specific models made for OEMs. The plant runs to IATF 16949:2016, certificate 0444022 issued by SGS.
Often, yes. Send the model, the part you need and a drawing or sample if you have one. We'll tell you whether we can make it and quote by model.
Yes. Windscreen is the usual word in India and the UK, windshield in the US. Both mean the front glass, and both are laminated so the screen cracks but stays in the frame.
No. Our windshields are laminated, because a broken front screen has to stay in place. Toughened glass, called tempered glass in the US, goes into side windows, rear glass and cabin panes.
Toughened glass can't be cut, drilled or edged after toughening, so every hole and notch is made first. For a laminated windshield, the drawing fixes the size and curve so the screen sits right in its frame.
