Delhi’s public transport network is the lifeline of the National Capital Region. Every day, thousands of buses—from school buses carrying children to city transport fleets moving millions of commuters and luxury coaches travelling between cities—depend on one critical component for safety and comfort: their windows.

Whether you are a school administrator ensuring the safety of young passengers, a fleet operator managing city transport buses, or a coach builder looking for reliable glass solutions, finding the best bus glass manufacturers in Delhi is essential. This comprehensive guide explores everything you need to know about bus glass solutions—from laminated windshields and toughened side windows to emergency exit glass and aluminium window frames—and helps you find the most trusted manufacturers in Delhi.

The Growing Demand for Bus Glass in India

India’s bus transportation sector is expanding rapidly. According to industry reports, the Indian glass industry is valued at around ₹45,000–50,000 crore (USD 5.5–6 billion) as of 2025 and is growing at an estimated CAGR of 8–10%. The automotive segment represents a significant portion of this market, with the automotive tempered glass market showing impressive growth.

Key drivers of bus glass demand in Delhi include:

Expanding public transport networks – Delhi Transport Corporation (DTC) and state transport undertakings continuously add new buses to their fleets
Growing school bus fleets – Increasing number of schools and student populations drive demand for safe school buses
Private bus operators – Growing demand for intercity and intracity bus services
Bus body building industry – Delhi and surrounding regions host numerous bus body manufacturers
Replacement demand – Existing buses require regular glass replacement due to wear and tear

North India’s Leadership in Automotive Glass

The North India region leads the automotive glass market, driven by concentrated automotive manufacturing hubs, established OEM supply chains, and strong vehicle assembly presence. Haryana and Delhi NCR, in particular, have emerged as the preferred destination for automotive glass manufacturing and supply.

AIS Windshield Experts recently expanded its network to 28 centres across Delhi NCR, opening new locations in Noida Extension, Greater Noida, Dilshad Garden, Mayur Vihar, and Narsinghpur (Gurugram). This expansion reflects the growing demand for automotive glass services in the region, including commercial vehicles like buses and trucks.

Types of Bus Glass Solutions

Bus windows come in several configurations, each designed for specific applications and safety requirements.

Glass Type	Description	Primary Application	Key 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	Breaks into small, blunt pieces; scratch resistant; high safety in breakages
Sliding Windows	Windows that slide horizontally or vertically	Passenger windows	Provides ventilation; available in larger sizes; fully framed sliders
Fixed Windows	Permanently sealed windows	Passenger windows	Maximum structural integrity; no moving parts
Emergency Exit Windows	Push-out or break-out windows	Emergency egress	Quick opening in emergencies; meets AIS-068 standards
Aluminium Window Frames	Pre-assembled frames with glass fitted	Complete window units	Saves installation time; ensures consistent quality; custom-built

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.

Toughened glass used in automobiles offers high safety in case of breakages and is scratch resistant.

Sliding Windows

Sliding windows are a common feature in many buses, providing ventilation for passengers. These windows slide horizontally or vertically within a frame, allowing passengers to control airflow.

Features of sliding bus windows:

Available in larger sizes
Fully framed sliders for better vibration resistance
Heavy-duty profile for durability
Glass choices: Clear, coloured, flat, or curved
Any combination of fixed and sliding windows

Fixed Windows

Fixed windows are permanently sealed in the bus structure. They offer maximum structural integrity and are typically used in areas where ventilation is not required or where sliding windows would compromise safety.

Emergency Exit Windows

Emergency exit windows are a critical safety feature in all buses. These windows are designed to open quickly in emergencies, allowing passengers to evacuate the vehicle.

Types of emergency exit windows:

Push-out windows – Designed to open outward to provide for emergency egress
Break-out windows – Designed to be broken in emergencies using emergency hammers

Aluminium Window Frames

For bus body builders, pre-assembled units offer significant advantages. DURATUF’s aluminium window frames for buses come with glass already fitted inside the frame at the factory. DURATUF started manufacturing aluminium windows for urban bus applications where high technology is deployed to design and manufacture custom-built windows complying with production specifications.

Safety Standards for Bus Glass in India

Bus window glass must comply with stringent safety standards to ensure passenger protection.

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 Toughened (Tempered) and Laminated Safety Glass
IS 2553 (Part 2):2019 – Specifies requirements for safety glass used in road transport

Front windscreens must be made of single piece laminated safety glass, plain, flat/curved with curved corners with PVB film as per IS 2553 (Part-2) 2019.

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.

AIS-063: School Bus Safety Standard

AIS-063 (Amalgamating Amendments 1 to 9 & Amd. No. 10) outlines the specific requirements for school buses, including design, structural strength, emergency exits, seating, and safety measures like first-aid kits and fire extinguishers.

Why Standards Matter

Non-compliant glass can:

Fail to protect passengers during accidents
Shatter dangerously upon impact
Provide inadequate visibility in adverse conditions
Result in legal liabilities for bus operators and body builders

When choosing a bus glass manufacturer in Delhi, always verify that they use certified glass that meets IS 2553, AIS-063, and AIS-068 standards.

School Bus Glass Solutions

School buses carry the most precious cargo—children. Safety is paramount, and glass plays a critical role.

School Bus Windshields

School bus windshields must use laminated safety glass as per IS 2553 (Part-2) 2019. The laminated construction ensures that in case of impact, the glass cracks but stays bonded, protecting young passengers.

School Bus Side Windows

Side windows in school buses use toughened glass that breaks into small, blunt pieces upon impact, reducing the risk of injury to children.

Emergency Exit Windows

School buses must have emergency exit windows that comply with AIS-063 requirements. These windows must be capable of being opened from inside the bus in case of emergencies.

Key safety requirements for school bus glass:

Single piece laminated safety glass for windscreens
Toughened glass for side windows
Emergency exit windows that open quickly
Compliance with AIS-063 and IS 2553 standards

Coach and Luxury Bus Glass Solutions

Coaches and luxury buses require glass that combines safety with aesthetics and passenger comfort.

Acoustic Glass

Premium coaches often use acoustic laminated glass with a special PVB interlayer that reduces noise penetration, providing a quieter, more comfortable ride for passengers.

Solar Control Glass

Coaches travelling in hot climates benefit from solar control glass that reduces heat and UV radiation entering the cabin, keeping passengers comfortable and protecting interiors from sun damage.

Tinted Glass

Tinted glass offers privacy for passengers while reducing glare and heat. It is commonly used in luxury coaches and premium buses.

City Transport Fleet Glass Solutions

City transport buses face unique challenges—frequent stops, dense traffic, and high passenger turnover. Glass solutions for city fleets must prioritize durability and safety.

Durable Toughened Glass

City buses require side windows that can withstand constant opening and closing, vibration from frequent stops, and exposure to urban pollution. DURATUF’s side window glass for buses is designed specifically for these demanding conditions.
