AbstractWhen dealing with two interrelated parameters, here sound isolation and fire resistance, the challenge is not to gain in one at the expense of the other. That challenge is easily met with Group 0 fire stops, as long as the cavity between two sets of studs has an air gap of 25 mm or less. There is no flanking transmission of sound because the cavity is filled with insulation. With Group 1 fire stops, defined by the soft materials at the floor/wall junction, all flanking transmission of sound is absorbed by them. For Group 2 and Group 3 fire stops, flanking transmission occurs through the fire stops, more so with Group 3.
