The bathroom pod  is not a structural element subject to loads, so fire resistance is generally not a concern unless in some exceptional cases. Therefore, standard versions (both lightweight and concrete) do not have an REI classification.

For lightweight bathroom pods (CBL), fire resistance is achieved by inserting mineral wool inside the steel frame and adding one or two layers of Fermacell on the exterior side of the pod (depending on the required REI rating).

For bathroom pods in concrete (CBM), fire resistance can be calculated and achieved at two levels: 30 and 60 minutes, by improving the wall construction. This is done by thickening the walls and using a lightweight concrete mix (with expanded clay).

In any case, these solutions will be adjusted to meet the specific needs of the project.

Thermal insulation, on the other hand, is achieved by working on the materials, both those used in the shell and the cladding materials, and it is measurable.

Smoke tightness is achieved through both materials and construction details, and it is certified directly by the material suppliers based on the selected “package.” For the walls, reference can be made to the certifications from the manufacturer of Fermacell panels.
