Development of a Vibration-Damping, Sound-Insulating, and Heat-Insulating Porous Sphere Foam System and its Application in Green Buildings

Abstract With the development of green buildings, people pay more attention to quality of indoor sound environment, air sound insulation performance of floors and exterior walls plays a key role in today's green buildings. The thermal performance of the enclosure structure of floor and exterior wall heat transfer resistance, is an important factor in reducing building carbon emissions in green buildings. Therefore, in order to effectively ensure the improvement of the air sound insulation performance of exterior walls and floors, the sound insulation performance of floor impact, and the thermal performance of exterior walls and floors, a sound insulation and thermal insulation carbon porous ball foaming system is designed and applied in practical engineering. The changes in sound insulation and thermal insulation performance of buildings under different working conditions are analyzed, and the feasibility research conclusions of this material system to change the sound insulation and energy savings of green buildings are summarized.
