Lack of fire separation in the attic of old wooden multifamily buildings is an important cause of the rapid spread of a fire from a fire origin room to the whole building. This paper presents a design of party wall, composed of single layer of reinforced gypsum board on either side of the stud above the separation wall, suitable for existing buildings and compliant with the law on the basis of 3 series of fire tests; those reproducing fire after the penetration into the attic and ISO834 wall furnace tests with small-scale specimens and with full scale party-wall specimen.
