Fire Door Closer
A fire door closer is a mechanical device fitted to a fire door that returns it automatically to the closed and latched position after each use, ensuring the door maintains its fire resistance rating and prevents smoke spread. A correctly functioning closer is a mandatory fitting on all self-closing fire doors and its operation is verified during every fire door inspection under BS 9999.

- Intumescent SealPassive Fire ProtectionAn intumescent seal is a strip or compound fitted around the edges of a fire door that expands rapidly when exposed to heat, sealing the gap between the door leaf and frame to prevent the passage of fire and hot gases. Intumescent seals are a mandatory component of all fire door assemblies and their condition is checked as part of every fire door inspection under BS 9999.View definition
