Reduce product settling and application time.

INS500 Stabilized Attic Spray Insulation

A blended formula stabilized product, the INS500 is installed in attics with a fine water mist which activates a starch adhesive. This is an application preferred by many new construction installers because of desirable effects of requiring fewer bags to complete projects, as well as reducing product settling and decreasing application time.
