BAE Systems' glass-clad polycarbonate products are constructed using proprietary, polyurethane high-adhesion bonding layers to form a multi-ply composite laminate.

This capability provides latitude in the design process. The glass and polycarbonate composite laminate is superior to single material glazing concepts and provides three primary benefits:

• Up to 60% reduction in thickness and weight compared to conventional glass and air gap security systems
• Increased ballistic tolerance
• Structural integrity of polycarbonate with the weathering abrasion, chemical and flame resistance of glass

Armor window systems:

BAE Systems Armor windows are composite laminates of polycarbonate, glass and polyurethane that are 40 to 60% lighter and thinner than conventional glass designs. Multiple impact ballistic tolerance ranges from 17 gr. fragmentation to 20mm FSP and from .22 caliber handgun to in excess of .50 caliber armor piercing protection. Window configurations resistant to explosion shrapnel and blast overpressure exceeding 200 psi are also available. Armor window systems are non-spalling and provide:

• Extreme ballistic protection and tighter impact patterns
• Lighter weight
• Improved optical characteristics
• Higher visible light and infrared transmission
• All climate reliability

Electronic shielding:

Electrical interference and electronic threat protection is achieved through the use of a variety of transparent metallic coating systems within the window. A significant range of frequencies can be attenuated to prevent instrument interference or damage, electronic eavesdropping, and jamming. Effective shielding against threats including RFI, EMI EMP, NEMP and microwaves has been demonstrated in excess of 20 GHz. Similar transparent coatings with controlled resistivities can also promote RCS reductions. Transparent metallic coating systems provide:

• Maximum shielding effectiveness
• Essentially no target resolution loss
• High visible light transmission
• Compatibility with night vision goggles and infrared navigation aids
• No adverse affect on window optical quality or color recognition

Optical shielding:

Optical threats such as nuclear flash and the thermal effects of heat pulse, infrared and laser can be effectively attenuated or filtered in nominal window sizes through the use of special transparent coatings

Superior optical quality:

Armor window system optical properties include higher light transmission, excellent visual clarity and aircraft quality optics. Optical distortion and deviation are minimal, even in armor thickness exceeding 2 inches, wherein displacement is typically less than 3 mins. of arc.

All-weather vision:

BAE Systems laminated glass fixed windows and sacrificial panes are electrically heated for continuous all-weather vision. When powered, ice, frost, snow, and condensation are removed within minutes. This anti-ice/fog capability is achieved through the application of a thin, transparent, metallic coating to provide electrical heating of the laminate.

Total capability:

Available in performance ranges from 24 volt inputs to 440 volt marine requirements.

Universal applications:

The system can be incorporated within any of our laminated windows including Armor. Meets or exceeds MIL-W-18445.

Clear vision:

Continuous high light transmission clear coatings without frit lines or embedded wires to obscure vision.

Temperature/power control:

Sensing devices can be incorporated within the window to provide precise temperature control and power regulation. These devices are silent, reliable and more energy efficient than warm air blowers, providing a cost effective solution for new construction or retrofit requirements.
