Do packers need to be covered with FAS Fire Door Foam™?

No, packers do not need to be covered with FAS Fire Door Foam™, provided they are installed correctly. Plastic or timber packers can remain exposed as long as they are fitted flush with the edge of the door frame or cut back level with the frame edge. This allows the fire door sealing system to be installed in accordance with the tested configuration. Always refer to the relevant installation guidance, certification and fire test evidence to ensure compliance with the specified fire door assembly.
