Fire seal strips, also known as fire door seals or fire-rated seals, are specialized products designed to create a fire-resistant barrier between doors, walls, and other openings. Made from a variety of materials, including intumescent seals that expand when exposed to heat, these strips can withstand high temperatures and help contain fire and smoke within a designated area. This containment is vital during a fire, as it can provide occupants with precious time to evacuate and help firefighters effectively battle the blaze.
