Cell windows of the series METAS®

Security without grilles

The SAELZER METAS® cell window offers certified protection without grilles. Windows without grilles improves the acceptance of the therapy in forensic hospitals. The inmates in police station or in the court have without grilles not the oppressive feeling to be "imprisoned" (design options table below).

Tested from both sides

METAS® windows are tested on both sides in accordance with the European standard for forced entry resistance DIN EN 1627-1630):

Fixed glazing:
                         inside and outside, up to resistance level RC4
Operable window elements:
                         inside, up to resistance level RC3
                         outside, up to resistance level RC4

No risk for suicide attempts and vandalism

The window has no exposed edges inside. All fittings as well as the glazing bead and gasket are covered. Sash profiles and glazing beads are particularly massive, rounded and flush. The gap between frame and wing is covered so that no wire can be inserted to commit suicide.

Application

In detention facilities, courthouses, forensic hospitals and police stations.
