KILARGO IS8011SI MEDIUM DUTY AUTOMATIC DOOR SEAL - AVAILABLE IN VARIOUS SIZES
KILARGO IS8011SI MEDIUM DUTY AUTOMATIC DOOR SEAL - AVAILABLE IN VARIOUS SIZES
The Kilargo IS8011si is a medium-duty automatic door bottom seal that can be face-fixed or semi-rebated to single-action doors – the easy retrofit alternative to a fully mortised seal. Its spring-loaded mechanism drops the silicone gasket onto the floor as the door closes, sealing gaps of 3–15 mm against fire, smoke, sound and draughts, then lifts it clear as the door opens.
Key Features
What It's Used For
Choose the IS8011si when you need automatic door-bottom sealing on an existing door – fire door upgrades, smoke door compliance work, acoustic improvements to offices and meeting rooms, or draught-proofing in commercial and residential buildings. Face-fixing means it installs in minutes with the door still on its hinges.
It suits single-action doors in hospitals, schools, hotels and apartments, and pairs with Kilargo perimeter seals for a complete fire/smoke/acoustic doorset solution.

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.
How does the IS8011si automatic door bottom seal work?
A spring-loaded mechanism inside the seal lifts the silicone gasket clear of the floor the moment the door opens, so there is no drag or floor wear. As the door closes, an adjustable strike button presses against the door jamb and automatically drops the gasket down onto the floor, sealing the gap under the door.
Do I need to remove the door to install the IS8011si?
No. In the face-fixed configuration the seal simply screws to the face of the door bottom using the ferrules and mounting screws provided, with the door still hung. Semi-rebating into a 35mm x 14mm groove is optional where a flusher finish is preferred.
Is the IS8011si fire and smoke rated?
Yes. It is fire tested to AS 1530.4 in accordance with AS 1905.1 on proprietary fire door assemblies, holds medium-temperature smoke leakage approvals to AS 1530.7 (AS 6905) and conforms with BCA Specification C3.4 smoke sealing requirements. Always confirm the approval matches your specific door type with your fire door manufacturer or certifier.
What size floor gap does the IS8011si seal?
It automatically seals door-bottom gaps from 3mm up to 15mm. Measure the gap between the underside of the door leaf and the finished floor when the door is closed - if your gap falls outside this range, call Prime Hardware on 1800 329 028 and we'll recommend an alternative Kilargo seal.
Can the IS8011si be cut down to fit my door width?
Yes. Each standard length can be cut back on site to an exact dimension: 380mm cuts to 275mm, 600mm to 380mm, 820mm to 600mm, 920mm to 820mm, 1070mm to 920mm and 1220mm to 1070mm. Order the standard length that your door width falls within, then trim to suit.
What is the antimicrobial (AM) option?
The IS8011si can be ordered with an antimicrobial silicone gasket. The silicone is compounded with an additive that inhibits bacteria and mould growth on the gasket surface - the version specified for hospitals, aged care, laboratories and food-preparation areas. Select the Anti-Microbial option when ordering.
What is the handling time for this item?
This is a non-stocked, specialty architectural item ordered directly from the Kilargo factory. Allow a standard handling time of 5–8 business days after cleared payment before dispatch. If your project needs express turnaround, call Prime Hardware on 1800 329 028 to confirm current factory lead times.
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.
