Intumescent fire sleeve are essential components in fire protection systems, designed to prevent the spread of fire and smoke through openings in walls, floors, and ceilings. These fire sleeve are made from intumescent materials that expand when exposed to high temperatures, creating a barrier that seals off the opening and restricts the passage of flames and hot gases. Intumescent fire sleeves are used to maintain the integrity of fire-rated structures, providing crucial time for occupants to evacuate safely and for firefighters to contain the blaze. By effectively containing fire and smoke within a confined area, intumescent fire sleeves play a vital role in enhancing overall building safety and compliance with fire regulations.
