A Fire Rated Interior Door is specially designed to help slow the spread of fire and smoke within a building, providing critical time for safe evacuation and emergency response. Built with a solid or composite core and reinforced materials, these doors are tested to withstand high temperatures for a specific period, commonly 20, 30, 45, 60, or 90 minutes, in accordance with building code requirements.

Fire rated interior doors are widely used in residential, commercial, and multi-unit buildings, particularly between garages and living spaces, stairwells, mechanical rooms, and shared corridors. In addition to fire resistance, they offer enhanced durability, sound insulation, and security. Available in various styles and finishes, fire rated interior doors combine safety compliance with functional design, making them an essential component of modern interior construction.
