High-Performance Polycarbonate Windows Engineered for Extreme Environments

Yes. Polycarbonate is a durable, lightweight thermoplastic with up to 250 times the impact resistance of glass at roughly half the weight. That impact advantage is why it is used in applications that demand both durability and reduced weight, from heavy equipment to defense glazing.

Polycarbonate windows are highly resistant to impact, chemicals, and extreme weather, which makes them well suited to harsh industrial and heavy-equipment environments. Their light weight also makes installation and handling easier than glass, reducing both labor and the risk of breakage during service.

Uncoated polycarbonate is softer than glass and can scratch, which is why hard coatings matter. Five Star's Fusionite™ hard-coat is engineered for abrasion resistance, with Taber abrasion results of less than 2% haze, so coated windows hold up to repeated cleaning, weathering, and field use over a long service life.

Common options include anti-fog, anti-scratch (hard coat), UV-resistant, anti-static, anti-glare, anti-reflective, and chemical-resistant treatments. The right coating depends on the application; coatings are selected to match the window's operating environment and performance requirements.

For impact-driven applications, polycarbonate is the stronger choice. It offers up to 250 times the impact resistance of glass while weighing roughly half as much. Five Star windows add Fusionite™ hard-coat protection for scratch and weather resistance, combining the impact advantage of polycarbonate with the surface durability buyers expect from glass.

Cost depends on size, shape complexity, coatings, certification requirements, and order volume, so pricing is quoted per program rather than per unit. The best way to get an accurate figure is to share your application and target volume; OEM programs at production scale typically achieve a lower per-unit cost than one-off parts.

Yes. Custom prototypes are produced to your project specifications, typically delivered within two weeks of an initial consultation and CAD file submission, so you can validate fit and performance before committing to production.

Polycarbonate windows are used across automotive, motorsports and racing, heavy equipment and agriculture, mass transit, aerospace, and defense — anywhere impact resistance, optical clarity, and durability are critical.

The process begins with an initial consultation, followed by an NDA and CAD file submission. From there, the design and prototype phase validates the part before moving into full production.
