The I-CE Locking Systems Intumescent Self Adhesive Kit is designed for enhancing the fire resistance of an architectural tubular latch. The items in the kit are black intumescent strips that are self-adhesive for easy installation onto door latches. The kit is suitable for 100/127mm latches and it has a 1mm thickness, indicating compatibility with FD30 fire doors, which provides fire resistance for up to 30 minutes. These intumescent strips expand under heat, helping to protect the latch mechanism and prevent the passage of fire and smoke. The finish is self-colour, which means they have a natural appearance without additional coating, and they are meant to be installed discreetly where they will not affect the overall look of the latch or door.
