Security without grills
The aluminium window in the METAS® series has been specially developed to meet the requirements of police stations, courts, prisons, and forensic and military facilities. It offers protection on both sides against escape attempts from the inside and aided escape attempts from the outside. The special cell windows ensure the required level of security even without grilles.
Windows without grilles significantly improve rehabilitation acceptance in forensic clinics. With no grilles on the windows, inmates in holding cells in courts, forensic clinics or police stations are less likely to feel "incarcerated".
Testing on the opening and closing side
METAS® windows are tested in accordance with the European standard for burglar resistance DIN EN 1627-1630 in the following classes on both sides of the window:
- Fixed glazing: up to resistance level RC4 on the inside and outside
- Opening window unit: up to resistance level RC3 on the inside | up to resistance level RC4 on the outside
No opportunities for suicide attempts and vandalism
- The vent profiles and glazing beads are particularly solid, flush-fitted and rounded on request.
- The special design of the glazing beads prevents them from being removed, or the glazing gasket from being pulled out.
- It is therefore not possible for the inmates to take out the glazing.
- The special profile design means that both fixed lights and side-hung vents can be constructed in a way that prevents suicide attempts.
- The fittings are concealed, eliminating a further opportunity for suicide attempts, and it is not possible to remove the window vent.
- To reduce the risk of suicides and vandalism, window handles are not used on the opening window vents.
- The side-hung vent is only opened and closed for cleaning and ventilation by means of a special key held by staff. It is also tamper-proof.
Use
For high-security cells (German Federal Court of Justice) in prisons, holding cells in courts, forensic clinics, police custody facilities, military buildings and other facilities that require cells of this type.

Further technical properties
| Hardware | The hardware is installed concealed. No window handle is installed to prevent suicide and vandalism. |
Profile widths | Despite the high security components, the profiles are very small. |
| Glazing beads | Window sash and glazing beads are rounded and flush and offer therefore no risk of injury. The glazing bead can’t be removed and the glazing gasket can’t be pulled out by the inmates. |
| Installation | Installation in several building materials permitted. |
Areas of application
View
Left: The inmates can operate the outward-opening top-hung vent by means of a tamper-proof turn knob, while the internal perforated sheet protects against attempts to climb out or harm themselves.
View
Left: Inmates can open the windows themselves for regulated ventilation to supply fresh air. Right: The side-hung vent can only be opened by staff for cleaning; the window handle is removed afterwards.
