Advanced Polycarbonate Windows for Mass Transit Vehicles
Transform your transit fleet with American-made polycarbonate windows and composite panels — engineered for municipal buses, school buses, charter buses, light rail, subway cars, trams, commuter rail, high-speed rail, and people movers.
When transit glazing fails, passenger safety, fleet uptime, FMVSS No. 217a anti-ejection compliance, and operating cost efficiency are all at risk.

By leveraging proprietary technologies and a commitment to sustainability, we empower transit agencies and original equipment manufacturers (OEMs) to build safer, more efficient fleets that meet modern transportation challenges.
What Happens When Transit Glazing Fails
Without proper materials and coatings, transit vehicle windows can shatter, crack, scratch, or fail prematurely under the demanding conditions of public transportation — exposing passengers and drivers to safety risks, agency procurement to compliance gaps, and operators to costly fleet downtime.
When transit glazing fails — in service or in accident scenarios — it creates real operational risk:
- Passenger injury risk from shattered glass during accidents, collisions, or vandalism incidents
- FMVSS No. 217a anti-ejection and ANSI Z26.1 visibility compliance gaps
- Costly fleet downtime, replacement cycles, and rising operating costs
- Reduced fuel efficiency and missed emissions targets when window weight isn't optimized
Mass Transit Window & Composite Manufacturing Capabilities
From initial design consultation through scalable fleet production — Five Star supports the complete mass transit window and composite panel program lifecycle with proprietary Fusionite™ coatings, precision forming, CNC machining, and ISO 9001:2015 quality systems.
Proprietary advanced coatings deliver superior scratch resistance, UV protection, and longevity, applied with precision for consistent performance across all transit products.
Advanced forming processes enable creation of complex shapes and large-scale windows — from flat panels for buses to curved windshields for high-speed rail.
High-precision machining ensures every window and panel component fits perfectly, reducing installation time and improving reliability across transit fleet rollouts.
Products designed to meet or exceed FMVSS No. 217a anti-ejection glazing and ANSI Z26.1 visibility safety glazing standards for federal and industry compliance.
Fiber-reinforced composite panels for interior partitions and exterior side panels — lightweight, durable, and customizable to vehicle finishes.
Rapid prototyping and scalable manufacturing — capable of meeting both small transit agency needs and large OEM fleet rollouts with consistent quality.
Mass Transit Window Performance Requirements
Polycarbonate windows for mass transit vehicles must meet strict demands across six performance areas:
| Requirement | What It Means in Practice |
|---|---|
| Impact Resistance | Up to 250 times more impact-resistant than glass — withstands vandalism, accidents, and thrown objects without shattering |
| Optical Clarity | Approximately 90% light transmission — comparable to glass, with no optical distortions for drivers or passengers |
| Lightweight Construction | 50% lighter than glass — reducing vehicle weight up to 30% for measurable fuel efficiency and lower emissions |
| FMVSS & ANSI Compliance | Meets or exceeds FMVSS No. 217a anti-ejection glazing and ANSI Z26.1 safety glazing visibility standards |
| Coating Performance | Fusionite™ scratch, UV, and chemical resistance validated for harsh transit environments and frequent cleaning agents |
| Custom Geometry | From flat panels for buses to complex, curved windshields for high-speed rail — produced to exact vehicle specifications |
