The products we use at DuPage Insulators are the highest quality


Cellulose Loose-Fill

Cellulose loose-fill insulation is made from wastepaper (such as used newsprint and boxes) that is shredded and pulverized into small, fibrous particles. Chemicals are added to provide resistance to fire and insects. Also, less energy is required to produce loose-fill cellulose.


Fiberglass Insulation

Fiberglass loose-fill and batt insulation are made from molten glass that is spun or blown into fibers. Most manufacturers use 20-30% recycled glass content. Loose-fill must be applied using an insulation blowing machine and is designed for attic and closed-cavity installations.


Foam Insulation

Foam insulation is a two-part liquid that is sprayed in place by specially trained and experience contractors only. The liquid mixture expands quickly and foams up to fill all gaps in your home’s structure. It cures to form a fully adhered, solid, monolithic micro-cellular insulation envelope.


Rock Wool Insulation

Rock wool (or slag wool) loose-fill and batt insulation (similar to fiberglass) are spun from blast furnace slag (the scum that forms on the surface of molten metal) and other rock-like materials instead of molten glass. The production of rock wool uses byproducts that would otherwise be wasted.
