Mass transit windows must perform through vibration, weather, repeated cleaning, public-facing use, and long service intervals, while supporting scalable OEM manufacturing and consistent fleet performance.
Lightweight Performance for Fleet Efficiency
Less weight than traditional glazing supports vehicle efficiency, easier integration, and better long-term fleet performance.
Durable Surfaces for Daily Service
Built for repeated cleaning, weather, vibration, and long service cycles in passenger-facing environments.
Engineered Fit for Complex Platforms
Custom formed windows and transparent panels designed for repeatable OEM fitment across bus, rail, and shuttle programs.
Lifecycle Cost Efficiency
Fewer replacements and lasting durability deliver better long-term value across high-volume transit programs.
Polycarbonate Windows for Transit Platforms
We support transit OEMs with custom formed windows and transparent panels designed for fit, durability, optical clarity, and production readiness across bus, rail, and shuttle platforms.
Our transit-specific glazing approach is built around durability, safety compliance, and lifecycle cost savings, with Fusionite™ hard coats for daily cleaning and CGIII-grade glazing that meets FRA Parts 223 and 238 for rail.
