AbstractThis paper is the fourth of a series of papers that provide an overview of work conducted by NRC in the past years on flanking transmission. NRC-IRC has carried out extensive studies to characterize flanking transmission through various building components and assemblies in the Flanking Facility1. One of the studies is to examine the effect of resilient channels on ceiling flanking paths. The floor-ceiling assembly in apartment buildings separates two different dwellings and the gypsum board ceiling is usually mounted on resilient channels to meet the requirements of the building code. However for row housing, the floor-ceiling assembly separates two rooms of the same dwelling and typically the floor is not sound or fire rated.. In this case, the gypsum board ceiling is often directly attached to the floor joists and ceiling flanking transmission paths between the two side-by-side rooms shown in Figure 1 can reduce the apparent STC significantly. This paper describes the improvement due to the use of resilient channels.
