  • Patent number: 8302280
    Abstract: An appliance includes a housing having top and bottom panels disposed opposite each other and a plurality of walls connected to the top and bottom panels. The top and bottom panels and the plurality of walls define a cavity of the appliance. The housing also has an outermost surface about which a polyurethane foam is disposed. The polyurethane foam reduces noise and vibrations emitted from the appliance during use and has a density of from 20 to 50 pounds per cubic foot (pcf). The polyurethane foam also has a damping factor of at least 0.2 measured at a temperature of from 40° C. to 60° C. Furthermore, the polyurethane foam has a k-factor of less than 2.0 btu-in/hr-ft2-° F. which reduces an amount of energy required to operate the appliance. The appliance is formed by applying the polyurethane foam to at least one of the top panel, bottom panel, and plurality of walls.
