Harden Architectural Security

High Security Aluminum Windows


DOS certified to withstand 5 or 15 minutes of simulated “mob” attack. 15 Minute models are also certified to resist rifle-level ballistic rounds. Both models are available as non-operable systems with optional deal tray or deal drawer and engineered blast load rating up to 40 psi / 300 psi-ms and beyond.

Design Overview

ANTI-TERRORISM LEVEL SECURITY where conformance to U.S. Department of State forced-entry / ballistic resistant threat levels and high blast protection is required

ENERGY EFFICIENCY where window thermal performance is important to overall building design considerations

CONDENSATION RESISTANCE thermal break vastly improves the frame’s ability to resist interior sweating and freezing

ARCHITECTURAL APPEAL provides the look of a commercial aluminum window system and complements modern architectural design

DESIGN FLEXIBILITY where architectural or security concerns require the use of large windows, ganged window systems or unique shapes

DURABILITY high strength aluminum alloy provides maximum durability and low maintenance

Harden’s FE/BR Windows safeguard prominent and mission critical buildings, guard houses, control rooms, cashier areas, executive offices and anywhere the highest levels of protection, aesthetics and sustainability are important considerations. Engineered blast resistance may be added for more comprehensive security.

Aluminum Windows are ideal for facilities where the aesthetics of aluminum and the thermal properties of thermally-broken systems are critical. FE/BR versions satisfy specific forced-entry, ballistic and blast resistance requirements of the U.S. Department of State.

Tested to Department of State Standard SD-STD-01.01 Rev. G (Amended), Harden Aluminum FE/BR Windows offer an ideal solution where the call for high ballistic and forced-entry resistance competes with targets for design excellence. The WAFV-05 and WAFV-15R all-aluminum, fixed window designs are tested and certified to withstand simulated “mob” attack for 5 minutes and 15 minutes respectively. The WAFV-15R is also resistant to 5.56 M193 & M855 and 7.62 M80 ballistic rounds. Both models can be engineered to resist blast loads up to 40 psi / 300 psi-ms and beyond.

Applicable Standards, Testing and Certifications
  • Department of State, SD-STD-01.01 Rev. G (Amended): Certification Standard – Forced Entry and Ballistic Resistance of Structural Systems
  • ASTM E283: Standard Test Method for Determining Rate of Air Leakage Through Exterior Windows, Curtain Walls, and Doors Under Specified Pressure Differences Across the Specimen
  • ASTM E331: Standard Test Method for Water Penetration of Exterior Windows, Skylights, Doors, and Curtain Walls by Uniform Static Air Pressure Difference

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

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.
