Tecwool® F - Fire belt barrier system/roof firebreak

Safety Regulations against Fire in Industrial Facilities indicate that, when a dividing wall or a splitting construction element in fire prone areas connects into the roof, the resistance of the latter will be at least equal to half of that established for the construction element in a 1-metre firebreak. The firebreak could be:

  • Roof built-in as long as the firebreak presence is justified after non-resistant roof parts collapse.
  • Fixed to the roof structure when it has the same fi re stability as the firebreak resistance required.
  • Made of a 1-metre wide barrier underneath the roof fixed to the diving wall, providing the fire resistance required. In no case should the barrier be installed at a distance greater than 40 cm from the roof lower part.

mercor tecresa® has designed and conducted this solution pursuant to the following European Standard (Document/Protocol): “Fire Resistance Test of dividing wall/roof firebreak,” the classification obtained being EI-60 y EI-120.

TEST


Norma : Fire resistance test protocol for
fire belt barrier system/roof firebreak.
Laboratory :TECNALIA
Test Nº :060930-001-1 Horizontal. 060930-001-2 Inclined.

SOLUTION


1. 10×100 mm metal frama anchor.
2. 46x36x0,6 mm. stud
3. 48x36x0,5 mm. wall support section.
4. 4,2×27 mm. sheet metal screw.
5. Metal-ribbed mesh.
6. Tecwool® F (thickness of 37 mm).
7. Partition Wall.

 

Application

We build a framing square with 48x36x0,6 mm uprights, respecting the dimensions stablished on the details for the horizontal and inclined
configurations.

The union between profiles is made by 4,2×27 mm metal-metal screws. The
framing squares are placed each 750 mm and fixed to the support work by
dowel and screw of 10×100 mm, at least two fixations per upright.

Three master omega profiles type 45x15x0,6 separated each 500 mm and fixed by 4,2×27 mm metal-metal screws.

The nervometal Tecmesh will be fixed to the support structure on its omega  profiles by self-tapping screws and the appropriate washer.

We will spray 37 mm of Tecwool® F mortar over the nervometal.

The stripe has been tested horizontally and inclined making an angle of 30º to the horizontal. These configurations allow an installation on works in configurations from 0º to 50º of inclination to the horizontal, provided the assembly system and the maximum distances indicated and reflected previously in the different construction assembly details are respected.
