Siniat Nida shaft 75A50

A casing systems of risers is used to hide all kinds of installations in a building. Due to the possibility of smoke or fire spreading to other levels of the building, the risers must be adequately protected. For this purpose, systems based on 12.5 mm, 15 mm, 20 mm or 25 mm plasterboards are used. The plasterboards are fixed to the intermediate support structure or directly to the walls and ceiling. The casing systems of risers using plasterboards help protect against the spread of fire to the EI 120 fire resistance class. An additional feature of these systems is possible acoustic protection from sounds coming from inside the shaft, caused for example by air flow, sanitation system or vibration of the installation.

Nida 75A50 is a shaft protection with Nida Plasterboards sheating (2x12,5mm - one sides) on a parallel structure made of C50 profiles. Its a standard shaftwall with different performance (depends on the used plasterboard)
