Ballistic Resistant Steel Windows UL 752 / NIJ III BR & BLAST

Harden Architectural Security

Ballistic Resistant Steel Windows

UL 752 / NIJ III BR & BLAST

Tested to withstand rifle-level ballistic threats for UL 752 levels 5 and 8, NIJ III and 7.62 x 39 rounds. Available as non-operable systems in various shapes with optional deal tray and engineered blast load ratings up to 40 psi / 300 psi-ms and beyond.

Design Overview

ANTI-TERRORISM LEVEL SECURITY where the threat of rifle-level ballistic and high level blast attacks exist

MINIMAL SIGHT LINES where a limited view of the window’s framing system is an important component of the overall building design

ARCHITECTURAL DESIGN the ability to form numerous shapes and configurations facilitates integration with other architectural elements

DESIGN FLEXIBILITY where architectural or security objectives require the use of large or ganged window systems

DURABILITY galvanized, structural steel provides maximum durability and low maintenance

Harden Steel Ballistic Resistant Windows offer an ideal solution where the call for high ballistics resistance is combined with requirements for minimalistic or uniquely shaped frames. The WSFV-N-B series are tested to meet multiple firearm threat levels including UL 752 (Levels 5 & 8), NIJ III and 7.62 x 39 rounds. The WSFV-N-EX is engineered to resist blast loads up to 40 psi / 300 psi-ms and beyond. Custom designs are available to meet combined blast and ballistic threats.

Installation Considerations
  • Windows are fully glazed at the factory, and require only minimal preparation prior to installation
  • Sub-frames can be shipped in advance of factory glazed window assembly
  • Three different methods of installation into the structure, depending on the stage and type of wall construction:
    • Pre-drilled and tapped plate-type embeds cast into concrete
    • Pre-drilled and tapped steel tube-type sub-frames bolted into the wall
    • Pre-drilled and tapped steel tube-type sub-frames welded to the wall structure
Maintenance

Regular inspection of window, trim and flashing is recommended.

Availability & Cost

Window systems are typically manufactured to order and subject to production lead times at the time of purchase.
