In addition to fire protection, it is also important to prevent propagation of smoke inside the building or its separate rooms. For these purposes smoke-control doors are used. This type of doors is fitted with sealing on four sides and a self-locking mechanism. Smoke-control properties can be obtained with additional fitments added to a fire-resistant door. It is useful to manufacture fire-resistant doors combined with smoke-control features.
