Tecwool® F - Partition wall / large format cladding

Non-bearing partitions performing separation functions between fire compartments, must have a fire resistance as indicated on the UNE EN 1364-1 standard.

When conducting a fire resistance test of nonbearing elements, part 1: walls, an edge is left free, the standard allows to increase the width dimensions.

Regarding height extension, the standard is clear and concise. When the construction is tested with a minimum of 3 meters, it is possible to increase it up to 4 meters.

On numerous occasions we find partition walls higher than 4 meters. mercor tecresa® is pioneer on the development of large dimension partition walls and offers the most efficient and confortable solution for this type of works.
Consult our commercial department.

On the other hand, every time a compartment is broken, for example the services crossing, it is necessary to seal the gaps produced by them.
Consult the Tecsel® Sealing System catalogue to find the most appropriate solution.

Laboratory: CIDEMCO
Test Nº: 27916


1. 0,6 mm corrugated sheet.
2. 3,5×25 mm self drilling screw.
3. 46x36x0,6 mm stud.
4. 60x60x1,5 mm. metal structure.
5. Tecwool® F (49 mm thickness)
6. 48x30x0,5 mm metal runner.


Fix the 60x60x1,5 mm metal structure (consult our commercial department for
dimensions and fixations).

Fix the 48x30x0,5 mm metal runners over the modulation of the metal structure and over them, the 46x36x0,6 mm metal runners every 600 mm by
3,5×25 mm self-drilling screws.

Afterwards, place the 0,6 mm corrugated sheet and affix it to the studs with 3,5×25 mm self drilling screws. Lastly, apply Tecwool® F mortar over the corrugated metal sheet.

The surface to be protected should be free from dust, oil, waste, poorly attached particles, paint leftover, etc.

It is recommended to use water with the application hose to wash dirt away from the faces. This will also help achieve a thermal balance between the mortar and the applied surface.

Tecwool® F can provide different finishings: rugged, smooth, painted, etc., according to different aesthetic requirements. Once the spread is completed and in order to obtain a smooth finishing, a roller should be used and pressed slightly over the wet mortar until the desired finishing is obtained. It is possible to paint the mortar with elastic acrylic coatings to form a steam barrier. Before painting the mortar should be completely dry (28 days).

Once spread, mortar should be water sprayed superficially to ensure optimum
settling of the cement.
