摘要：
Presented article deals with sound insulation properties of timber structures' envelope walls. Particularly, the influence of heavy board ventilated facade on laboratory airborne sound insulation R and R-w in dB was studied. The installation method and gaps between facade boards can cause building defects originating in overrating the influence of ventilated cladding on envelope wall acoustic parameters. Real constructions were built for the experimental purposes and measurements, one with gaps between boards and one with simply eliminated gaps for mutual comparison. The results obtained were processed to make tables and graphs and to derive recommendations for the design of this type of constructions involving the general installation method of facade boards. Detailed results are depicted in conclusions.
