IS8520si
A heavy duty, automatic door bottom seal designed for high performance acoustic door systems. This seal can be face-fixed, semi-rebated or fully mortised into the bottom edge of single action doors. The seal has a spring loaded mechanism which lifts the seal clear of the floor, in a parallel motion, as soon as the door is opened. Pressure against the door jamb on the adjustable brass strike button operates the seal automatically.
Face-fixed: The seal is fixed to the face of the door bottom using the long fixing screws provided. (see detailed fitting instructions). A set of glass-filled, nylon end plates ensure longevity of the seal mechanism.
Semi-rebated: When the seal is to be semi-rebated, the seal is mounted into a stepped rebate: a 44mm deep x 21mm wide machined groove on the side of the door to which the seal will be positioned. The seal can be screw-fixed into position and fitted with the cast aluminium end plates provided.
Fully-mortised: When the seal is to be fully-mortised, the seal is mounted into a 44mm deep x 21mm wide machined groove and screw-fixed back into the door stiles via the cast-aluminium end plates, holding the seal in place.
Australia Made
Ensuring the highest standards of production, this product is proudly manufactured in Australia.
Seals for this designation are designed to control smoke at ambient temperature conditions.
When installed as per our instructions, these seals offer very low frictional forces, thereby eliminating any increase to the opening and closing forces of the door – an important consideration when meeting the requirements of AS1428/1.
Reducing air movement within buildings assists in improving the overall energy efficiency of the building.
Designed to contain smoke at 200 degrees C for 30 minutes.
Seals for this designation are designed to conform to the NCC Specification C3.4 for ‘Smoke Doors’
Fire tests to AS1530/4 have been conducted on one or more proprietary fire door constructions to show that the addition of these seals will not affect the already established fire resistance levels of the fire doors. Strict compliance with AS1905/1 requires each door type to be tested with each item of hardware. For each project, please check with the respective fire door manufacturer to verify that their door construction has the relevant listing for Kilargo Integrity seals.
Seals for this designation have been tested in accordance with AS1530/7 for smoke leakage, providing ambient or medium temperature leakage rates across various pressures.
Testing for door assemblies incorporating these seals has been conducted to AS1191 and/or ISO140 Part 3/ISO10140.2.
