Blow-in cellulose insulation has been around since the 1920âs and consists predominantly of recovered or recycled newsprint and/or corrugated cardboard, treated with a fire retardant. Three main types of blow-in cellulose insulation are used in residential application: loose fill, stabilized, and wall-cavity spray. Spray-in Foam Spray-in or spray-on polyurethane foam expands to fill cracks and voids to form a tightly sealed barrier.
There are three general types of blown insulation materials currently available: fiberglass, cellulose and rock wool. Fiberglass loose-fill insulation is made glass and sand that are spun or âblownâ into fibers. This type of insulation is great for wall cavities and attics. It can properly insulate an area and protect it too from moisture which could lead to the formation of fungus and mildew. In this age or recycling, most manufacturers use 20% to 30% recycled glass.
