Secondary Security Glazing

Enhanced protection without disruption.

Secondary Security Windows provide additional security in instances where existing windows need additional reinforcement with an added level of resistance to help fend off attacks without the need to modify or alter the original window.

Designed to be unobtrusive to avoid drawing attention to high-security areas within a building, Secondary Security Windows are frequently used to protect staff in secure enclosures, such as cash offices and other higher risk areas, without changing or removing existing windows.
