RWS Insulation Services specializes in installing cellulose insulation in a range of project types. Spray-applied cellulose fits snugly in wall cavities, limiting inefficient air pockets. It acts as a noise reducer and is resistant to mold, moisture, insect infestation and fire. Wet-spray cellulose uses a unique system that combines dry, loose cellulose insulation with water, which adheres to the wall cavity. The sprayed insulation forms full cavities, reducing air infiltration. Cellulose is made from recycled newsprint and paper and is treated with non-toxic fire retardants.
