tuletõkkeuks

Tuletõkkeuks is an Estonian term that translates to "fire door." It refers to a specialized door designed to prevent or slow the spread of fire and smoke within a building for a specified period. These doors are a crucial component of passive fire protection systems, intended to compartmentalize a building and maintain escape routes for occupants during a fire.

The primary function of a tuletõkkeuks is to maintain structural integrity and prevent fire from breaching the door for a rated duration, such as 30, 60, 90, or 120 minutes. This rating is determined by standardized testing and indicates the door's ability to withstand fire exposure without collapsing or allowing significant fire penetration. They are typically constructed from materials that are inherently resistant to fire, such as steel, timber with intumescent strips, or specialized composite materials.

Tuletõkkeuksed are commonly installed in locations that require a higher level of fire safety, including stairwells, corridors, escape routes, and between different fire compartments. They are often equipped with self-closing devices, such as hydraulic closers, to ensure they are always shut or close automatically when released, thereby maintaining their protective function. Regular inspection and maintenance are essential to ensure that tuletõkkeuksed remain operational and effective in the event of a fire. Their proper installation and functioning are subject to building codes and fire safety regulations.
