Dimensionally Stable Fiberglass
Dimensionally stable (DS) fiberglass is a patented process by Guardian Fiberglass, Inc., called UltraFit DS. Relatively new to the market, DS fiberglass spray-on insulation is applied by a process that is similar to that used for stabilized cellulose insulation. A fine mist of water is combined with the loose-fill fiberglass and a dry adhesive binder. As in wet-spray cellulose applications, the excess fiberglass material is scrubbed off the face of the studs and is immediately recyclable.
