fire rated interior door
A fire rated interior door represents a crucial safety component in modern building design, engineered specifically to prevent or slow the spread of fire and smoke between different areas of a structure. These specialized doors combine robust construction materials with advanced engineering to provide reliable fire protection for designated periods, typically ranging from 20 minutes to 3 hours. The core construction usually features fire resistant materials such as mineral cores, steel reinforcement, or treated solid wood, encased in heavy duty steel or specially treated wooden frames. These doors incorporate intumescent seals that expand when exposed to high temperatures, effectively blocking smoke and flames. The doors are equipped with self closing mechanisms and positive latching hardware to ensure they remain sealed during fire events. Each fire rated interior door undergoes rigorous testing to meet strict safety standards and building codes, including resistance to heat transfer, structural integrity during exposure to extreme temperatures, and the ability to prevent smoke penetration. These doors are essential in commercial buildings, healthcare facilities, educational institutions, and multi unit residential complexes, where they serve as critical components of fire separation assemblies and emergency evacuation routes.
