Standard building solutions in which this type of material isapplied are: double walls, heavy or light, in which materials are placed in the middle of them,single or combined with other elements and also other applications such as solutions related toabsorption process, in which acoustic wool is combined with perforated panels in front it.One of the problems presented by materials manufactured using polyester fibers is that theyare obtained from petroleum, which is a limited resource and whose price will only increasein the coming years. For this reason, we are trying to develop new absorbent wool using wastepolymeric materials, like fibres obtained from PET recycled bottles, Along with the economicand environmental, advantages, this allow us to use the same thermo-fusion techniquecurrently employed to join raw polyester fibers.In this work we will present a brief explanation of manufacturing processes and after that, apreliminary acoustic study focused on the quantification of absorptive and isolationparameters of different material composition.37º <strong>IAHS</strong> <strong>World</strong> <strong>Congress</strong> On Housing Science 335
