Fire sectorization: New partition walls EI-120/180/240 with Tecbor® Boards

Actualizado a fecha: 7 February, 2019

Either because there are long-distance evacuation routes or too many people, Fire Protection regulation obliges, in certain circumstances, to create different spaces to take refuge in case of fire. For example, a protected stairway or dividing the space into two or more fire sections. This allows us to save people quickly through the fire sector and reduce the evacuation routes distances.

Depending on the building height, fire load, location of the industrial premises regarding their neighbour’s, etc., the regulation determines the stringency level in minutes of fire resistance that we will need on partition walls. Our Technical Department has developed three new solutions with Tecbor® Boards.

We refer to three new tests of sectorization with partition walls that require two, three and four hours of fire protection. These tests are made under the current regulation, which contains this type of solution, the UNE-EN 1364-1, Tests of fire resistance on non-structural elements. Part 1: Walls.

We have carried out this new test with an advantage over the previous one. We have reduced the density of rock wool in its interior to a much more commercial format going from 100 Kg/m3 to 40 Kg/m3, which has reduced its weight, cost and the ease of finding it available at any construction products warehouse.

In this new test, like the previous one, we have reduced its cost and ease of assembly by reducing the density of the rock wool blankets it carries inside.

This test is new and gives us an idea about the good performance of the Tecbor Board against fire. While other solutions do not bear 4 hours of exposure to fire in the oven, our Tecbor Board holds up perfectly and meets the criteria of Insulation and Integrity for four hours (EI-240).


The Tecbor® Boards are made of Magnesium oxide, silicates and other additives that offer the widest range of solutions of protection against fire. We achieve a great resistance with the lowest necessary thickness, which allows us to save space and not to overload the structural elements.
