Have a restaurant that will be going into the basement area of a building. The area is fully sprinkled. Above the restaurant on the first floor is a brewery and a yoga area. The building is completely sprinkled on both floors.
The owners of the new restaurant wants the ceiling/floor joist to remaining with no coverage and apply with fire rated paint and then apply roxul acoustic insulation panels 3.5 inches thick between each joist.
Would this be allowed??
