Abstract
This issue shows the close correlation between thermophysical and acoustic properties of roll flooring materials, such as linoleum, rubber linoleum and carpet covering. The thermophysical properties are characterized by the heat absorption index, S, and the main acoustic feature is the index of impact noise insulation improvement, ΔLnw. The analyses of equations for boundary conditions, as the smooth transition of temperature and heat flow through the interface of two media, allowed revealing the mathematical similarity between acoustic and thermal wave transmission processes, in particular, between the thermal and acoustic impedances. This similarity provided the basis for correlation research between the heat absorption specific coefficient and the index of impact noise insulation improvement values. Therefore, the correlation formula for different types of roll flooring materials was obtained.

The measurements of heat absorption specific coefficient, S, and the index of impact noise insulation improvement, ΔLnw, for roll flooring material samples were taken in thermal physics laboratory and acoustic chambers of NIISF RAASN (Research Institute of Building Physics of the Gosstroy in the Russian Federation)
Summary
The civil buildings floors constructions, including the load-bearing ceilings, should comply with wide range of requirements. Among them there are strength, abrasive resistance, manufacturability, heat transmission resistance, sound insulation, waterproofing, ecological safety (it should not be emissions of dust, dangerous gases, harmful compounds and smells). Within this framework, the floor constructions for different civil buildings premises can have a lot of varieties of main functional layers, fig. 1. The floor structure with the use of roll floor covering materials is one of the most popular variants for the upper floor layer. Practice at building and construction design of civil buildings shows wide appliance of roll materials in floor covering. The linoleum, the rubber linoleum and the carpet covering are among them
