Description
Sanctuary stabilized borate formula is engineered to fill tiny crevices and gaps, creating a dense, scientifically advanced barrier capable of reducing the power of sound by up to 60-percent. As cellulose insulation that can be blown-in or spray-applied, Sanctuary can be easily installed over existing insulation and unlike batt or roll alternatives, it is engineered to fill every gap, void and hard-to-reach place without time-consuming cutting and fitting. Installed in attics, walls, ceilings and floors, Sanctuary keeps homes cooler in the summer and warmer in the winter, reducing heating and cooling costs by up to 25-percent. Sanctuary has a class 1/A fire rating, qualifies as a fire-blocking material and has been proven to be 57-percent better at resisting fire than most other common type of residential insulation.
