Røgbarrierer

Røgbarrierer are fire-resistance-rated construction elements designed to limit the spread of smoke between compartments in a building during a fire. By containing smoke, they help protect evacuation routes, facilitate visibility for occupants, and aid firefighters by reducing the spread of heat and smoke. They are used in many building types, including multi-story housing, offices, schools, and public facilities.

A røgbarriere typically consists of fire-rated walls or partitions, often extended with fire doors, fire-rated ceilings or floor assemblies, and sealed joints. Openings and penetrations for cables, pipes and ducts are fire-stopped to maintain barrier integrity. The barriers are designed to be continuous across floors and around stair cores, corridors, and other critical areas so that smoke cannot easily bypass them. In addition, passive barriers are commonly complemented by active systems such as door closers, intumescent seals, and dampers, as well as stairwell pressurization or exhaust to control smoke movement.

Regulations and standards vary by country, but the concept is consistent: røgbarrierer must resist smoke passage for a defined period and preserve the integrity of escape routes and occupied spaces. Fire-resistance ratings and performance of barrier assemblies are specified in national or regional codes and standards, such as EN 13501-2 and related fire-testing procedures in many regions.

Maintenance is essential: regular inspection of seals, doors, joints, and penetrations; replacement of damaged components; and verification that fire-stopping remains intact. Poorly maintained barriers can fail to contain smoke and compromise safety.
