1mm Universal DIN Lock Intumescent – 30 Minute Fire Protection (For ZOO DIN Locks)

This 1mm universal DIN lock intumescent is designed to provide 30-minute fire protection for doors fitted with ZOO DIN mortice locks, including the ZDL range. When exposed to high temperatures, the intumescent material expands to seal gaps around the lock case, helping to maintain the fire integrity of the door assembly.

Slim and discreet, the 1mm profile allows it to be easily fitted behind the lock without affecting door preparation or hardware alignment. Suitable for use on fire-resisting doors in commercial and public buildings, it supports compliance with fire door installation requirements when used as part of a certified door set.
