The Growing Automotive Glass Market in India

The auto component industry generated a turnover of US$ 78.7 billion (Rs. 6.73 lakh crore) in FY25, demonstrating a 14% compound annual growth rate in recent years.
Bangalore’s Role in the Automotive Glass Ecosystem
Bangalore has emerged as a significant hub for automotive glass manufacturing and supply in southern India. The city’s strategic location, excellent connectivity, and growing industrial infrastructure have attracted major glass manufacturers and suppliers. The Bommasandra Industrial Estate has become a key location for automotive glass production.
In order to establish itself in southern India, DURATUF started Bangalore Safety Glass Works Pvt. Ltd. (BSGW) in 1996 in the Bommasandra Industrial Estate, Bangalore. The company is a conglomerate of seven manufacturing units located in Delhi, Haryana, Indore, and Bangalore.
Impact Safety Glass Works Pvt. Ltd. , another Bangalore-based company, has a 35,000 sq. metre production facility in Bangalore with a daily capacity of 100 large glasses to cater to the heavy vehicle segment and 500 small windscreens for smaller vehicles. The company is working with all leading bus manufacturers in the country, including Tata Marcopolo, Ashok Leyland, Eicher and Mahindra Navistar.
Types of Bus Glass Solutions
Bangalore suppliers offer a comprehensive range of bus glass products for various applications and safety requirements.
| Glass Type | Description | Primary Application | Key Safety Features |
| Laminated Glass | Two glass layers bonded with a PVB interlayer | Windshields for buses | Cracks but stays bonded on impact; prevents occupant ejection |
| Toughened/Tempered Glass | Heat-treated glass, 4-5 times stronger than ordinary glass | Side windows and rear windows | Breaks into small, blunt pieces; scratch resistant |
| Acoustic Glass | Laminated glass with acoustic PVB interlayer | Premium buses, luxury coaches | Reduces noise penetration; improves cabin comfort |
| Solar Control Glass | Coated glass that reduces heat and UV radiation | All bus types | Lowers cabin temperature; protects from UV rays |
| Aluminium Window Frames | Pre-assembled frames with glass fitted | Complete window units | Saves installation time; ensures consistent quality |
Laminated Glass for Windshields
Laminated glass is the standard for bus windshields. It consists of two glass layers bonded together with a PVB (polyvinyl butyral) interlayer. When impacted, the glass cracks but the PVB layer holds the pieces together, preventing them from entering the cabin. This is particularly critical for bus drivers who need protection from flying debris and for passengers in case of accidents.
DURATUF’s laminated windshields for buses are manufactured to the highest safety standards, with the company producing glasses as large as 1.83 m by 2.6 m for buses.
Toughened Glass for Side Windows
Toughened (tempered) glass is heat-treated to be four to five times stronger than ordinary glass. When it breaks, it shatters into small, blunt granules rather than sharp shards, reducing the risk of injury. DURATUF’s side window glass for buses is toughened to handle constant vibration, repeated opening and closing, and exposure to sun and rain.
Impact Safety Glass Works has a daily capacity of 100 large glasses to cater to the bus segment and is capable of making side glasses for buses of sizes 1.7 to 2.4 metres.
Aluminium Window Frames
For bus body builders and fleet operators, pre-assembled units offer significant advantages. DURATUF’s aluminium window frames for buses come with glass already fitted inside the frame at the factory. This eliminates the need for on-site cutting, sealing, and adjustment, saving time and ensuring consistent quality.
Safety Standards for Bus Glass in India
All bus windshield and side window glass manufactured and sold in India must comply with stringent safety standards. Understanding these standards is critical for fleet owners and operators to ensure passenger safety and regulatory compliance.
IS 2553: The Primary Standard
The Bureau of Indian Standards (BIS) has established IS 2553 as the primary standard for safety glass used in motor vehicles:
- IS 2553 (Part 1):2018 – Classifies safety glass into two types: Toughened (Tempered) and Laminated Safety Glass
- IS 2553 (Part 2):2019 – Specifies requirements for safety glass used in road transport
Front windscreens shall be made of single piece laminated safety glass, plain, flat/curved with curved corners with PVB film as per IS 2553 (Part-2) 2019 latest. Windscreen glasses shall meet the requirements of BIS 2553: Part II-1992 or latest and that of CMVR and Bus Code.
Good quality windscreens maintain the visibility of the driver as well as not causing any injury during accidents.
AIS-068: Bus Window Safety Standard
AIS-068 (Amd. No. 1) sets the requirements for windows fitted on buses, ensuring proper ventilation, safety glazing, emergency accessibility, and protection against accidents. This standard regulates window design and glazing, ensuring proper ventilation, emergency access, and accident safety, which enhances passenger security.
Why Standards Matter to Fleet Owners
For fleet owners and operators, non-compliant glass can:
- Fail to protect passengers during accidents
- Shatter dangerously upon impact
- Provide inadequate visibility in adverse conditions
- Result in legal liabilities and regulatory penalties
- Lead to costly fleet downtime and repairs
When choosing a bus glass supplier in Bangalore, always verify that they use BIS-certified glass that meets IS 2553 and AIS-068 standards.
