Maximum Security Louvers
Ventilation Coupled With Combined Threat Resistance
Tested to Department of State Standard SD-STD-01.01 Rev. G (Amended) and UL 752 Level 8, Harden Maximum Security Louvers offer the utmost in DOS certified ballistic and forced-entry resistance while providing essential ventilation for mechanical equipment used to support building operations. Certified to withstand a simulated “mob” attack for 60 minutes and 5.56 M193, 5.56 M855 and 7.62 M80 ballistic rounds, these louvers are designed to provide the ultimate in protection. Insect screening to impede pest infiltration is provided as standard.
Design Overview
ANTI-TERRORISM LEVEL SECURITY where conformance to U.S. Department of State forced-entry / ballistic resistant threat levels is required
DESIGN FLEXIBILITY numerous cladding and trim options offer the ability to complement other building materials
DURABILITY structural steel materials and high-quality finishes provide extreme durability and low maintenance throughout the life cycle
The uniqueness of Harden Maximum Security Louvers can be seen in their simple, efficient design. Structural steel “T” frames combine with chevron-style inserts to create a system that is effective in both shedding rain and deflecting bullets. Widely accepted as the basis of design on many projects, the louvers have been utilized in a wide variety of applications.
Factory welded to simplify installation in the field, modules are constructed in sizes up to 4′ x 10′ (1.22 m x 3.05 m). Louvers can be ganged together to create an even larger louver wall.
