Intumescent Lock Protection

Intumescent Lock Protection

Our intumescent lock protection solutions are designed to safeguard the most vulnerable areas of a fire door—around the lockset. Lock cut-outs can significantly reduce the fire resistance of a door, which is why applying protection is crucial for maintaining compliance and safety. At Noberne, we provide tested intumescent kits and lock sleeves that expand under extreme heat, sealing gaps and insulating metal components against heat transfer. These products are essential for preserving the integrity of fire doors and helping contain fire and smoke within the compartment of origin.

Enhancing Fire Door Performance

Fire doors are only as effective as their weakest point, and unprotected ironmongery—especially locks—can be a major risk. Our intumescent lock protection products activate in the presence of fire, expanding to fill any voids and reinforcing the door’s core structure. This expansion reduces the risk of premature door failure by insulating the lock case, latch, and strike plate, helping to contain fire and delay its spread. Whether you’re installing a new door set or upgrading an existing one, intumescent lock protection ensures fire rating compliance without compromising functionality. 

Easy-to-Fit Intumescent Lock Kits for Fire Rated Doors

Our lock protection kits are compatible with most standard lock types and can be integrated with additional fire door ironmongery protection, including hinge pads and fire rated letter plates for a complete passive fire protection system.
