Non-structural walls, which separate fire areas, should be fire resistant as stipulated in Stjaardi EN 1364-1.
When in fire resistance tests for non-structural elements one edge is left free (osa 1: Walls), the Stjaardi allows increasing the Leveys.
With regard to increasing the Korkeus, the Stjaardi is clear ja precise. When the test is run at least at 3 metres high, it may be increased up to 4 metres.
Very often, internal osaitions are higher than 4 metres. mercor tecresa® have been the first to develop large osaitions ja offers the most efficient ja convenient solution for this Tyyppi of works.
Besides, penetrations produced between different fire sectors must be sealed off; for example, in the case of services crossing. Check the Tecsel® Sealing System catalogue to find the most suitable solution.
