KILARGO KP3107SS RIGID INTUMESCENT FIRE & SMOKE SEAL
KILARGO KP3107SS RIGID INTUMESCENT FIRE & SMOKE SEAL
The Kilargo KP3107SS is the KP3107 heavy-section intumescent fire seal with an incorporated offset brush pile for smoke resistance – made for the proprietary aluminium bullnose meeting stiles of double-action fire doors. The 31 mm x 7 mm core handles fully developed fire; the brush wipes the stile gap against smoke every day.
Key Features
What It's Used For
The KP3107SS seals the meeting stiles of double-action (swing-through) fire door pairs, where gaskets can't survive the two-way swing – the offset brush pile sweeps the gap against smoke while the intumescent core protects it in fire.
Fitted into the proprietary aluminium bullnose stile sections of double-action fire doorsets.

Compliance & What It Means
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.
Why a brush pile instead of a fin on the KP3107SS?
Double-action doors swing both ways, so a wiping fin would fold and tear. The offset brush pile sweeps the meeting-stile gap in either direction of swing, providing smoke resistance a fin can't deliver on these doors.
How does an intumescent fire seal work?
The core is an intumescent material that stays inert at normal temperatures. In a fire, the heat makes it expand to many times its original volume, packing the gap between door and frame with an insulating char that blocks flames, heat and hot toxic gases - preserving the doorset's fire rating for its tested duration (up to 2 hours).
Which fire doors is the KP3107SS approved for?
It is fully tested to AS 1530.4 for up to 2 hours on proprietary fire door assemblies in accordance with AS 1905.1. Approvals are specific to tested door types - always confirm with your fire door manufacturer or certifier that the seal is covered for your doorset and required rating (FRL).
