2084522 9119064 PCTABS00008 A floor construction on a support means of timber joists (10) consists of floor boards (11, 12) laid on battens (13) each having a lower horizontal surface faced with a material (14) for attenuating transmission of sound. The battens (13) consist of plywood strips about 5 mm thick and the same width as the joists (10). The battens (13) are less stiff than the floor boards (11, 12). Thus, energy delivered to the sound attenuating material (14) is increased. The material (14) included open-cell and closed-cell layers (14B, 14A); and the upper layer (14A) has lateral flaps (15) folded down and nailed to the sides of the joists (10). The floor construction has improved sound attenuating qualities; the reduced batten thickness allows easier installation in certain circumstances; and the lateral flaps also assist installation.
