What It’s Used For

Floors get re-levelled, carpets removed, doors trimmed and suddenly a fire door hangs 40mm above the slab. The FDBU60 turns that write-off into a compliant door again, sealing gaps that no conventional seal can approach.

Kilargo 4000 Series threshold plates may be added for aesthetics and disability compliance. Select -35 or -45 to match your door thickness, and confirm approvals with your door manufacturer.

Specifications

Compliance & What It Means

Fire rated AS 1530.4 / AS 1905.1 (up to 2 hours). Fully tested to AS 1530.4 for up to 2 hours on proprietary fire door assemblies in accordance with AS 1905.1. In a fire, the intumescent core expands to many times its size and seals the gap, blocking flames, heat and hot toxic gases keeping the door assembly’s fire rating intact.Brings non-compliant fire doors back to compliance. AS 1905.1 sets strict limits on fire door clearances. Where gaps exceed the allowable limit, the door fails inspection. This upgrade seal is the cost-effective fix it restores compliance without rebuilding or replacing the door.Smoke sealing BCA/NCC Specification C3.4. Conforms with Building Code of Australia (NCC) Specification C3.4 smoke sealing requirements. Smoke not flame is the biggest killer in building fires, and C3.4 sets out how door gaps must be sealed so escape routes stay clear of smoke.

Fire and smoke approvals apply to tested, proprietary door assemblies. Always confirm suitability for your specific door type and required rating with your fire door manufacturer or building certifier.
