How to Use This Calculator

Enter the threat level per GSA/DoD standards and standoff distance in feet.
Set the window area and aspect ratio.
Review the required glass makeup (monolithic, laminated, or blast film) and frame anchorage forces.
Verify the hazard rating meets the target protection level (low, medium, or high).
Use the anchorage forces in structural design to specify connection hardware.
