Improvement of Acoustic and Thermal Comfort by Turning Waste into Composite Materials

Journal Title: Romanian Journal of Acoustics and Vibration - Year 2013, Vol 10, Issue 2

Abstract

This paper presents research on developing new types of composite materials with sound absorbing and thermal insulating properties, in order to improve the acoustic and thermal comfort of an enclosure. Thus, in order to achieve these materials, several wastes were used (fir sawdust, beech sawdust and particles of recycled rubber), as well as polyurethane binder, which was used as a matrix. The produced materials were characterized both acoustically (sound absorption coefficient) and also in terms of heat transfer (thermal conductivity). Results show that the achieved materials have very good acoustic and thermal properties and that these properties vary according on the nature of the waste used as raw matter in producing these materials. Sound absorbing and thermal insulating materials can be used to obtain an acoustic and an adequate thermal insulation of enclosed spaces: in residential buildings, commercial buildings, industrial buildings, education/ school buildings, on building sites, on highways, roads and streets, airports, ports, railroads etc.
