    Dow Great Stuff Pro Gaps and Cracks

    In the United States, GREAT STUFF PRO™ Gaps & Cracks was the first foam to be recognized as a fireblock, which means it resists the free passage of flames to other areas of the building through concealed spaces. The foam is a bright orange color, easily identifiable by U.S. code officials.

    Considering the combined open space created by gaps, cracks and penetrations in the average home can total as much as a 4' x 4' window left wide open, it’s no wonder that air infiltration is one of the biggest threats to a home’s energy efficiency. And as uncontrolled air movement drives up energy bills, it may also increase the potential for mold, mildew and other moisture-related problems.
