The objective of the article is to assess acoustic insulation of a wooden floor structure between stories in a pre-war residential building. The measurements involved acoustic insulation against impact sounds and airborne sounds. The article presents the results of acoustic tests for noninsulated floors and then for floors insulated with mineral wool. First, the results of the research were analyzed in terms of single-number acoustic insulation rates. These results were compared to the standards and findings described by other researchers. Then, an analysis was carried out for the processes as a function of frequency. The conclusions described in this article allow us to assess the applied acoustic insulation system.

The outer-wall thermal insulation system has been wide used in civil engineering as an effective energy-saving measure. At present, the organic flammable thermal insulation materials such as EPS and XPS are used in outer-wall thermal insulation system in China, which leads to great fire damage probably. The rock-wool is described in detail on its merits such as good thermal insulation performance, good sound insulation performance, light weight, low thermal conductivity coefficient, incombustibility, innocuity and stable chemical capability. Two popular outer-wall external thermal insulation systems are introduced. The construction sequence of the outer-wall external thermal insulation system with rock-wool slabs, mortar and thin layer plastering technology is described.
