HANDI-FILL® WALL SEAL EFFECTIVELY FILLS BLIND WALL CAVITIES WHERE THERE MAY BE LITTLE TO NO EXISTING INSULATION.
Now there is finally a way to properly seal and insulate existing wall cavities without removing sheet rock. In the past, this has been done mainly by utilizing blown cellulose, a recycled news paper product. The drawbacks of cellulose are that it does not air seal and it settles over time leaving a void at the top. Handi-Fill® Wall Seal is the only polyurethane foam on the market designed specifically for wall cavities. The competition uses Tripolymer based foams which tend to shrink over time and completely loose their ability to air seal.
