Security windows SECUFIRE®

Security windows in steel tube frame construction for elegant, slim elements with expansive glazing.

Multiple tests against various threats

Security window in steel tubular frame construction for elegant, slimline structures with a high proportion of glass. The stable yet slimline steel tubular frame construction in the SECUFIRE® series provides elegant protection against multiple threats. Even with the combined protection against a range of different types of threat, high resistance classes can be achieved with a high proportion of glass:

Forced entry and break-out resistance up to RC4 (test on both sides), bullet resistance up to FB4-NS and protection against bomb attacks (100 kg of explosives | distance of 22 m). In addition, fire protection up to F90/EI90 can be provided depending on the design, place of use and the other security requirements.
