ABSTRACT:
A sealing and insulation device for the space between spaced apart surfaces having an envelope fabricated of a resilient, flexible material filled with a resilient insulation material. The sealing and insulation device has a width dimension at least as great as the distance across the space between the surfaces to be sealed. By removing air from the interior of the sealing and insulation device the width dimension of the device is reduced to less than the transverse dimension of the space to be sealed. Once the shrunk device is positioned, air is allowed back into the sealing and insulation device enabling the device to resiliently turn back towards its original width dimension such that the sealing and insulation device expands into abutting contact with both spaced apart surfaces across the space therebetween. The purpose of the device being both to seal and insulate in thermal applications such as a water heater and acoustical applications such as dishwasher. In the thermal application such as the water heater it is sealing the flow of a liquid foaming agent and then insulating by impeding thermal transfer. In the acoustical application it is sealing an opening to prevent direct transmission of sound waves through an opening and insulating by absorbing sound waves generated by the appliance.
