Fire retardants reduce the tendency of materials to burn and work in conjunction with other materials to slow the spread of fire. The KBS panel seal consists of mineral wool panels coated withone of our best fire retardants, KBS Coating. Only the exposed side of the panels and the visible penetrating items have to be coated with fire retardants such as KBS Coating in order to prevent the fire from spreading as quickly to other areas.
According to the requirements, KBS panel seals can be installed as a single or double panel seal. The fire retardants with which the panels are coated are a water-based, ablative, fire protective coating suitable for penetration seals and fire protection of cables or other utilities.
KBS Coating lasts for the lifetime of cables, is highly flexible, is totally weather- and water-resistant, and is compatible with various chemicals.
Any mineral wool panels with a minimum density of 150 kg/cm3 can be used for KBS fire retardant panel seals. If not available on the local market, they can be supplied by the distributor. KBS coating is produced only by Grünau Illertissen GmbH, maintaining a quality system which fulfills the requirements of ISO 9001.
Panel Seals Technical Information
The KBS panel seal, combined with fire retardants, is used to create a fire-resistant closing of any size of opening in walls or floors, providing a smoke- and gas-tight seal around all penetrating utilities such as cables, cable trays, pipes and ducts.
KBS panel seals have been tested and approved world-wide and have received various ratings depending on type and national standard. (Please see list of international test reports on back page.) Please note the following results:
- Single Panel Seal (panel thickness 50-60 mm): Rated up to 120 min.
- Double Panel Seal: Rated up to 180 min.
Panels are coated with KBS fire retardant coating at approximately 3 kg/m2 on the exposed (visible) side only. This means that the same amount is used whether it is a single coating or a double panel seal. Panels may be coated with fire retardants by spray or trowel on-site, or pre-coated. Pre-coated panels are also available from the distributor. In the double panel seal, there usually remains an air space between the two panels since each panel is installed flush with the outside of the wall.
In all KBS panel seals, only the exposed (visible) penetrating items (cables, pipes, etc) must be coated with KBS coating or other fire retardants for a distance away from the seal. This distance is specified in national tests and differs from country to country and according to requirements.
Retrofitting of additional utilities is achieved with ease in a KBS panel seal. The opening for the penetrating item is cut as accurately as possible with a pointed saw knife and sealed with KBS sealant after the installation of utilities. Where the opening has been cut larger than the penetrating item, loose mineral wool should be stuffed tightly in the remaining space before applying KBS sealant.
