Feuerhemmende

Feuerhemmende refers to the property of a material or construction to resist the passage of fire and hot gases for a specified period. This resistance is crucial for passive fire protection, which aims to compartmentalize buildings and prevent or slow down the spread of flames. Materials are tested and classified according to various international standards, such as EN 13501-2 in Europe or ASTM E119 in the United States.

The fire resistance rating, often expressed in minutes (e.g., F30, F60, F90, F120), indicates how long a barrier, such as a wall, floor, or door, can maintain its integrity and insulation properties under fire conditions. Integrity refers to the ability to prevent the passage of flames and hot gases, while insulation relates to limiting the temperature rise on the unexposed side.

Common materials and systems that exhibit feuerhemmende properties include fire-resistant boards, mineral wool insulation, intumescent coatings, fire-rated sealants, and specially designed fire doors and windows. The performance of a feuerhemmende element depends on its composition, thickness, installation method, and any penetrations made through it. Proper design, material selection, and installation are essential to ensure effective fire containment and protect lives and property.
