Does only the choice of classified structures – walls, roofs etc. – affect the level of fire protection?
Classified structures prevent fire from spreading from one part of a building to another. You should, however, also choose classified coatings for escape routes. Fire protection is a matter of saving lives, i.e. occupants should be able to escape if and when a fire breaks out. Q: I am in the process of building a boiler room with brick walls. The building inspector demands that the ceiling must conform to a 60 min fireproof requirement. I have got wooden beams on my ceiling. I cannot use concrete or bricks. Is there anything I can do? A: Not to worry. The problem is easily solved. Fire resistance class REI 60 that the building inspector means, can be obtained for a normal wooden ceiling by using stone wool structures. A steel wire is attached to the bottom surface of the roof supports horizontally in relation to the supports, e.g. a 1-2 mm wire nailed to the bottom of k 300 mm supports. The purpose of the wire is to keep the insulation in place even if the lower structure is destroyed
