Bullet & Blast Resistant Operable Windows

An operable window introduces moving parts and seams, which naturally present unique engineering challenges for ballistic defense. We design our systems so that the tracks, sashes, and locking mechanisms offer the exact same protective integrity as a solid wall. 

Here is how our operable systems manage active security:

• Multi-Level Ballistic Ratings: Our moving sashes are configured with UL 752-rated glazing and reinforced framing. This ensures targeted protection against specific caliber threats, covering everything from standard handguns to high-powered rifles.

• Precision Sliding and Hung Mechanics: Heavy ballistic glass can quickly bind or wear out standard window tracks. We utilize heavy-duty, low-friction balancing systems and roller assemblies to ensure projected-out, single-hung, or horizontal sliding configurations open smoothly with minimal physical effort.

• High-Security Latching Systems: A window is only secure when it stays locked against an aggressive threat. Our operable units feature heavy-duty, impact-rated locking hardware that tightly clamps the moving sash into the fortified frame, preventing forced entry or compression failures.

• Blast and Dynamic Impact Resistance: Moving windows must still contain the intense pressure of an explosive event. Our assemblies are structurally reinforced to transfer blast overpressure away from the glass and into the surrounding wall architecture.

• Integrated Transaction Accessories: To facilitate safe, high-volume exchanges, we can incorporate package drawers, secure document slots, and counter-mounted deal trays directly into the operable window framework.

• Acoustically Optimized Communication: Open windows allow for direct speech, but when secured, clear communication is still vital. We offer non-glare, natural voice transmission systems or integrated electronic intercoms to allow easy dialogue through a closed barrier.

• Discreet Architectural Profiles: Upgrading a high-visibility service counter does not require an industrial, institutional appearance. We powder-coat or anodize our precision-milled aluminum frames to match your existing interior millwork or exterior storefront facade.
