Intumescent Strips

Intumescent Strips, or fire door strips, are fitted to the door and, when exposed to extreme heat, expand to close any edges or gaps that may leave the fire door vulnerable to fire and smoke spread. 

Intumescent door strips are usually designed to provide up to 30 or 60 minutes fire resistance and help to contain the fire in one area and prevent it spreading. Use in conjunction with intumescent seals to offer the most fire protection in your fire doors.
