TECHNOLOGY

Blast-Proof windows and doors were developed by the world’s most experienced teams of engineers and other professionals in the field of blast mitigation and were subjected to a rigorous series of explosive detonations, structural stress, and AAMA testing. Blast-Proof systems operate a state of the art plant equipped with modern machinery dedicated to the manufacturing of blast mitigation window and entranceway systems. Our team is committed to the highest standards of quality, service, and support. Don’t hesitate to contact us with questions about your commercial and residential projects.

Blast-Proof System offers an extraordinarily sophisticated Energy-Absorbing system approach. This technology utilizes the window frames, glazing, hardware, and anchoring elements as energy dissipating components.

Upon impact produced by the dynamic load of the blast wave, the energy absorbing components undergo a gradual dynamic deformation, which absorbs a significant portion of the blast energy, and allows the window to stay in the opening, and continue to protect the building occupants.

The real-life experience of Blast-Proof System’s engineering team which include hundreds of thousands successful installations as well as the developing of numerous blast mitigation windows, doors and curtain wall systems, has provided Blast-Proof System with the expertise in designing and refining the product in order to meet the most demanding architectural criteria while providing the highest level of blast protection required.

All Blast-Proof System products are modular stackable units that are interconnected and can be installed mulled together within a single opening with no need for any steel mullions or other reinforcement.

“When blast pressure overcomes the strength of a conventional blast window, the thick glazing is projected into the protected space at high velocity, representing significant hazard to occupants of that area.”

“This ‘graceful failure’ of the Muntin window (an Energy Absorbing window developed by the Department of State) is in sharp contrast to the catastrophic failure mechanism of a conventional blast window manufactured with thick laminated glazing or monolithic tempered glass.”

TESTING

The B-Pro blast mitigation products have been tested for:

• DoD UFC4-010-01 ATFP criteria -2007
  - ASTM F1642 Hazard Rating
• GSA Performance Condition 2, 3a-3b
• AAMA requirements.

THE ENERGY ABSORBING ANCHOR (EAA)

Following extensive research, including hundreds of full scale blast simulations, Blast-Proof System has identified the most efficient energy dissipating component: the Energy Absorbing Anchor (EAA). The EAA is a small piece of galvanized steel sheet, which facilitates the transfer and dissipation of a significant portion of the blast load throughout the window and onto the supporting walls.

This allows Blast-Proof System to design light and economic windows, which in its turn allow the project architects and structural engineers to work freely with conventional wall materials that do not require reinforcement. The benefits of Blast-Proof System EAA have been utilized in numerous government and strategic projects by leading blast mitigation consulting firms ,such as Weidlinger Associates Inc.:

“...Weidlinger Associates Inc. (WAI) modeled and analyzed the Blast-Proof System... the benefits of the Energy Absorbing Anchor were significant... As a result of this study, WAI acknowledges the beneficial performance of Blast-Proof System and Energy Absorbing Anchor component.”
