What It's Used For

Fit the IS5161Hsi to sliding doors where smoke control or hygiene rules out a brush seal. The angled carrier lets the silicone fin reach across offset gaps and perpendicular surfaces.

Typical applications include warehouses, hospitals, car parks, plant rooms and commercial buildings with roller, tilt-up, sliding or automatic doors.

Compliance & What It Means

Antimicrobial silicone. The silicone is compounded with an antimicrobial additive that inhibits the growth of bacteria and mould on the gasket surface. This grade is specified for hygiene-critical environments — hospitals, aged care, medical suites, laboratories, commercial kitchens and food-preparation areas.

Smoke tested — AS 1530.7 / AS 6905. Holds medium-temperature (200°C) smoke leakage approvals to AS 1530.7, compliant with AS 6905 on proprietary door assemblies. This is the test the BCA relies on for smoke doors — it verifies the seal keeps hot, toxic smoke from leaking past the door for the required 30 minutes.

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.

Acoustic tested — AS 1191 / ISO 140-3 / ISO 10140-2. Acoustically tested in accordance with AS 1191, ISO 140-3 and ISO 10140-2 — the laboratory standards for measuring sound insulation. Correctly sealed doors are the difference between a quiet room and a noisy one; this seal is proven to cut sound leakage through the door gaps.

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.

Ordering & dispatch. This is a non-stocked, specialty architectural item ordered directly from the Kilargo factory line. Please allow a standard handling time of 5–8 business days after cleared payment before dispatch. Need it sooner, or not sure which seal suits your door? Call Prime Hardware on 1800 329 028.

Why choose the IS5161Hsi over an angled brush seal?

The continuous silicone fin forms an unbroken air seal, so it can hold back smoke and improve acoustics - things a brush's individual filaments cannot do. It also wipes clean for hygiene-critical sites.

Which fin size do I need?

The carrier accepts 13mm, 19mm or 25mm silicone fins (confirm fin length when ordering). Measure your gap and allow the fin to overlap it comfortably; call 1800 329 028 for help matching fin to gap.

What lengths are available?

Standard lengths are 1000mm and 2250mm, with 250mm increments available from 1000mm to 5000mm. Seals can be cut down on site for an exact door width.

I'm not sure this is the right seal for my door — can I get help?

Yes. Door sealing depends on your door type, the gap sizes and what you need to seal against (fire, smoke, sound, weather or drafts). Call Prime Hardware on 1800 329 028 with your door details and gap measurements and we'll confirm the right Kilargo seal, size and finish before you order.
