Intumescent Fire Seals and Fire Strips are essential to maintain the fire rating of fire doors. When the strips come into contact with heat, they expand to fill the gap between the edge of the door and the door frame to slow down the spread of the fire. Fire Strips can be either plain or with a brush or fin that offers smoke protection. Smoke Seals can be particularly useful as they can prevent the spread of toxic smoke to the rest of the building. Smoke inhalation is responsible for more deaths than a fire alone so this product can be life saving for people trying to escape from a building in the event of a fire.
