Aluminum Ballistic Resistant (BR) Windows deliver laboratory tested protection against rifle-level ballistic rounds in a complete system designed for energy efficiency and modern architectural appeal. Available in a wide variety of performance ratings for both fixed and teller window applications, they can also be engineered to resist significant blast loads with a “no hazard" rating. Ross aluminum window designs utilize high strength aluminum alloy components for durability and a thermally broken frame with industry leading U-values and condensation resistance.
