Description
Summary:The aim of this work is to evaluate the potential application of textile and polyurethane aqueous dispersion in insulation application in the form of a nonwoven polyurethane composite. Based on their properties, nonwoven are promising insulation solution for buildings. However, the major disadvantage is their flammability and their low mechanical property. The main purpose of this research is to improve physical, thermal and acoustical properties of these materials, by using a thin layer of polyurethane. According to the experimental results, it can be concluded that the PU layer enhanced the barrier properties of textile nonwoven. Moreover, it has a great effect on the sound absorption coefficient and thermal conductivity. The results of this study provide an effective solution for insulation application. Indeed, these alternative materials will contribute to the cost advantage as well as the green building initiative.
