Thermal Advantage is the leader in foam insulation in Arizona. Foam insulation fills in the voids between adjoining masonry blocks, making a home more comfortable and energy efficient, as well providing soundproofing. Foam insulation installs quickly, is safe, non-toxic, and pays for itself with year-round energy savings. And good news! Existing masonry can be easily retrofitted with new foam insulation, even where there was little or no insulation previously.
