Abstract: The present invention is a thermal and acoustic insulating sphere that has an evacuated hollow interior. The spheres are constructed of insulating materials, and the inner and outer surfaces of each sphere have highly reflective coatings evenly applied to them. The coatings applied to the inner and outer surfaces reduce the transmission of heat by conduction, convection, and radiation. Additionally, the spheres provide superior acoustic insulation due to the inability of sound to travel through the interior vacuum. The spheres can be used to produce insulating materials, for example, by embedding or positioning them within or between other materials, to provide thermal and acoustic insulation.

Abstract: Heat and Sound Insulation Ball (HASIB) is a hollow ball which has vacuum inside and is made of insulating materials like fiber-reinforced-plastic and glass. The inner and the outer surfaces of HASIB have non-conducting highly reflective coatings. HASIB is a much better heat insulator and its use can reduce the transmission of heat by conduction, convection and radiation. The use of HASIB for heat insulation can save energy and bring down the cost of heating in winter and cooling in summer. HASIB is also a better sound insulator since sound cannot travel through the vacuum inside it. HASIB can be used in the form of HASIB-wrap which can be made by gluing them between two sheets of plastic. HASIBs can also be embedded in the drywall used for the construction of houses to make the drywall a much better heat and sound insulator.
