KAISER ceiling sealing systems DS 90 / 120 mm and DS 90 / 74 mm ensure that the fire resistance class of the ceiling is maintained from EI30-EI90. In order to effectively prevent the transmission of fire and smoke gases when cables and electrical installation pipes are run through concrete or aerated concrete ceilings, these must be sealed in the same fire resistance class as the ceiling. This is ensured simply, quickly and safely by the ceiling sealing systems DS 90.
