Tecbor® Y Board - Wall 25 mm

Non-structural walls, which separate fire areas, should be fire resistant as stipulated in standard EN 1364-1.

When in fire resistance tests for non-structural elements one edge is left free (Part 1: Walls), the standard allows increasing the width.

With regard to increasing the height, the standard is clear and precise. When the test is run at least at 3 metres high, it may be increased up to 4 metres.

Very often, internal partitions are higher than 4 metres. mercor tecresa® have been the first to develop large partitions and offers the most efficient and convenient  solution for this type 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.
