Is Thermal Resistance Correlated With Sound Insulation?

An implementation of the sustainable development idea in the building sector stimulates search for materials and structures providing better heat insulation. Because the acoustical expectations and requirements also rise, a need for harmonization of both parameters increases. The article demonstrates differences between thermal and acoustical behavior of various building elements. The analysis of measurement results obtained for different structures demonstrates that finding a simple relationship between acoustical and thermal insulations is quite difficult. Tendencies observed in each case are rather opposite than parallel and materials or technical solutions that improve thermal resistance of a building partition often deteriorate its acoustic performance.
