Blown-In Insulation in the Plaster Walls

Bob again meets up with insulation contractor Joe Sheridan in the main house where the Cocoon insulation in being blown into the original plaster walls. To accomplish this, Joe's crew has drilled holes every 16 inches so that they are into every stud cavity. They drill one high and one low to acheive the proper density. First they apply it to the bottom and fill till it's solid in there - about 30 seconds on a bottom cavity. The installer can tell when it's filled from the pressure of the hose. The product will start backing into the hose. With experience you can hear it. Thge goal is to create maximum density in the cavities - leaving no air pockets. When the insulation process is complete a plasterer will have to come in and patch each hole individually. More information
