Balanced Hazard Protection.
Home Safe, Every Day.
Hazard and Blast Resistant Buildings
Patented FORTRESS Protective Buildings are blast resistant buildings constructed from modular components that provide design flexibility as well as multi-hazard protection from fragment, overpressure, thermal, toxic, and extreme weather events. Using innovative modular construction, our buildings are quickly fabricated, shipped, installed, and ready for occupancy.
We have partnered with industry leading companies to offer a turnkey blast resistant building that provides a high degree of protection from a range of hazards. Due to our patented modular design, site owners and operators not only benefit from knowing that building occupants will be protected, but can also appreciate that project costs and site disruption will be minimized.
Hazard Design Basis
3/4" steel required for same resistance to 1" projectile
8 psi, >>200 ms (very long) duration with minimum wall displacement
1/4" impinged saturated propane jet fire for one hour; <139°F inside air temperature
<0.1 ACH main building, <0.03 ACH interior SIP room
Extreme weather (i.e., Hurricane Cat 5 wind/debris)
Hazard resistant when it matters

Thermal: Panel and Joint Testing
See the results of a ¼-inch impinged saturated propane jet fire for 1-hour.
Thermal: Panel and Door Testing
See the results of a ¼-inch impinged saturated propane jet fire for 30-minutes.

“As FORTRESS’s Senior Construction Manager, my main goal with each project is to safely install and fitout our turnkey blast resistant building as efficiently as possible with minimal disruption to the site. What makes me proud is when I hand over the keys to the finished building, I get to congratulate the project team on not only purchasing a high value building, but ensuring that the building’s personnel are protected beyond blast – for thermal, fragment, and toxic exposure as well. We really are redefining protective buildings.”
