Protective Louvers
Protect Ventilation Openings & Equipment Against Blast, Ballistic & Forced-Entry Threats
Ventilation openings and exposed equipment can create vulnerable points in otherwise protected facilities. Philadelphia Safety Devices offers protective louvers designed to help address blast, ballistic, and forced-entry threats while allowing air to pass.
Applications include air handling units, rooftop equipment, building openings, and equipment located inside or outside protected structures. Louver designs and protection levels are selected according to the project’s threat conditions, airflow needs, and force protection requirements.
Need Help Selecting the Right Protective Louvers?
Our team can help evaluate your application, opening dimensions, airflow needs, and protection requirements to identify an appropriate solution.
Blast-Resistant Louvers
Fixed louver assemblies designed to mitigate blast effects while allowing airflow. These systems can help protect building openings, portions of a structure, and equipment requiring ventilation.
Ballistic-Resistant Louvers
Protective louvers constructed with specialized armor steel profiles to help shield openings and equipment against ballistic threats from multiple directions. Configurations are selected to meet the project’s required ballistic protection level.
Forced-Entry-Resistant Louvers & Shutters
Louver and shutter systems designed to resist forced-entry attempts. Optional reinforcement can provide additional ballistic and blast resistance where multiple threats must be addressed.
