Fire protection windows

from Wikipedia, the free encyclopedia

Fire protection windows prevent fire flashover on or in buildings .

Fire protection windows, like fire protection doors and other construction elements for openings in fire protection walls, have different fire resistance requirements, from 30 minutes (F30) to 120 minutes (F120) and more (classes of resistance time). Windows in the outside area are marked according to European rules. The classifications range from EI30 to EI90 (E = room closure; I = insulation). These classifications are supplemented by "C" (closing = self-closing) and / or by "S" (smoke = smoke-tightness) depending on the member state. A further differentiation is made with subscript numbers (subscript).

It is mostly fixed glazing that consists of a special frame (wood or aluminum) and fire protection glazing (monoglass or insulating glass). It can be used both indoors and outdoors. Statutory energy saving requirements, such as B. by the German EnEV , can be met by fire protection insulating glass.

In Germany, movable fire protection devices are subject to external monitoring. This serves to ensure compliance with the relevant approval and your processing instructions. Without this external monitoring, no movable fire protection devices may be brought into circulation.

For indoor use, the labeling is carried out on a label on the elements on which the approval, the manufacturer, the year of manufacture and the monitoring organization must be included. For windows for outdoor use, the CE mark and the provision of the declaration of performance are mandatory.

Fire protection windows are usually made of metal or wood.

Special designs

A special feature is the requirement for ventilation sashes or cleaning sashes in fire protection walls. Openable fire protection glazing is equipped with an attached closer, an integrated or a combination closer with smoke detector. The latter can be connected to a fire alarm control panel. This ensures the closure of the window and the associated fire protection. The use as a second escape route is another use of the opening of a wing in a fire protection wall.
