Does anyone out there have any experience with an expanding foam product called POLYMASTER. It is a product advertised for use in masonry cavities as an insulator/soundproofer. I was directed to an installer by a company that provides polyurethane foam when we determined that the expanding nature of their product would not allow for a retrofit into my existing closed stud cavities. I was considering blown cellulose, but the installer agrees that the polymaster can be shot through holes drilled into the top plates accessed through the attic, reducing the need for interior wall holes. My concerns are: 1) Will product deliver advertised R- value of 4.6/inch? 2)Can it get wet? 3)Is it better than blown cellulose? Has anyone out there had experience with this product? BUILDER BEAVER
