At NKA Caulking, we provide fire-rated caulking services across Melbourne, sealing gaps and penetrations in walls, ceilings, and floors to help contain the spread of fire, smoke, and toxic gases. We use FR-acrylic and fire-rated silicone sealants that are tested and compliant with AS1530.4, forming a key part of your building’s passive fire protection system.
