KILARGO IS7090SI ADJUSTABLE DOOR PERIMETER SEAL - AVAILABLE IN VARIOUS SIZES
KILARGO IS7090SI ADJUSTABLE DOOR PERIMETER SEAL - AVAILABLE IN VARIOUS SIZES
The Kilargo IS7090si is a self-adjusting, spring-loaded door perimeter seal for high-performance acoustic applications. Its unique mechanism automatically compensates for door movement and uneven doors while remaining mechanically adjustable (gaps 0–8 mm), with polypropylene fins inside the gasket housing adding extra smoke and acoustic sealing.
Key Features
What It's Used For
The IS7090si suits acoustic doors that move – heavy hotel and apartment entry doors, education and healthcare doors in high-traffic corridors – where a fixed seal would lose contact as the door settles. The spring mechanism keeps the gasket seated against the door face automatically.
Use it in lieu of door stops on non fire-rated frames, or on fire doorsets as tested on a 25mm frame stop. Specify a long-backset latch on rebated single-door frames.

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.
What does 'self-adjusting' mean on the IS7090si?
The gasket carrier rides on an internal spring. As the door warps, swells or settles over time, the spring keeps the silicone gasket pressed against the door face - no service call needed. It can also be adjusted mechanically if a specific compression is required.
Where is the IS7090si fitted on the door?
It is fitted around the door frame perimeter - across the head and down both jambs - in lieu of door stops (on non fire-rated frames) or over a 25mm stop on tested fire doorsets. The door bottom is sealed separately (pair it with a Kilargo automatic door bottom seal or threshold seal for a complete system).
Can the IS7090si be used on fire doors?
Yes - it is fire tested to AS 1530.4 in accordance with AS 1905.1 on proprietary fire door assemblies (certifications GVYI.R26629, GVWZ.R26629, GVWZ7.R26629). Confirm the approval covers your specific door type and rating with your fire door manufacturer or certifier.
What is the antimicrobial (AM) option?
Selecting the Anti-Microbial option supplies the seal with antimicrobial silicone gaskets, compounded to inhibit bacteria and mould growth on the seal surface - the version specified for hospitals, aged care, laboratories and food-preparation areas.
