The Bathroom Pod is not a structural element subject to fire loads; therefore the compliance to Fire-Resistance standard in not relevant but in exceptional cases. Therefore basic versions (both in concrete and steel boarded frame) have no fire rating.
In the case of the concrete pod (CBM), Fire resistance is calculable and can be achieved in two degrees: 30 minutes and 60 minutes, by upgrading the walls construction; for concrete pods by thickening the walls and using lightweight concrete mix (by means of expanded clay aggregate). With regard to steel pods (CBL), by including mineral wool inside the steel framing carcass and adding one or two layer of fermacell board (depending on the fire protection grade to be reached) on the outer side of the wall(s). In any case, this data and solution will follow up the specific project requirements.
Thermal Insulation, instead, is achieved by acting both on the pod shell structure and/or on the covering materials.
Smoke tightness is obtained both with materials and with constructional details, and it is directly certified by the suppliers of materials used in compliance with the “bundle” selected.
