Patent ID: 8647454

Claim:
A method of manufacturing a physical barrier configured to be installed on an object having an opening, comprising the steps: providing a carrier; determining a desired sound transmission characteristic of the physical barrier; determining an amount of a flowable sealer material necessary to achieve said desired sound transmission characteristic; applying said amount of said flowable sealer material to said carrier, including at least a perimeter of said carrier, said flowable expandable sealer material being configured to expand upon activation, wherein said flowable material has an expansion ratio greater than 100% and a viscosity that is sufficiently low to allow the flowable material to take on a shape defined by said carrier when the flowable material is installed to said carrier; and providing a handling structure on said carrier, said handling structure disposed within said perimeter of said carrier and configured to allow positioning of the carrier after the flowable sealer material is applied, said handling structure configured to be installed to the object with said carrier, said handling structure thereby remaining permanently installed with said carrier to the object after said carrier is installed to the object.
