At MWR Exterior, we specialize in blown-in insulation to maximize the efficiency of your home.



According to the U.S. Dept. of Energy, most attics aren’t adequately insulated. A typical home is likely to have less than R-20 attic insulation. But throughout most of Indiana, the DOE recommends that attics in be insulated to R-49 or more.

The process of adding insulation is quick and easy. Through the blown-in insulation method, a shredding and blowing machine is placed outside your home which forces the insulation through a long, flexible hose that extends into the attic where our technician directs the flow.

Blown fiberglass insulation can be installed directly over existing attic insulation, provided that the existing insulation is still in good condition.

Properly installed insulation makes it less expensive to keep your home in the comfort zone.

The combination of too little insulation and too much air leakage can waste a great deal of energy. That’s why home performance experts recommend that air-sealing improvements be combined with insulation upgrades.

When attic air sealing is combined with an attic insulation upgrade, it’s possible to reduce heating and cooling costs by as much as 40 percent. Wouldn’t you be interested in cutting your “comfort” costs nearly in half?

If you have an unfinished attic, you’ll be surprised at how affordable it is to seal air leaks between your living space and the attic and upgrade attic insulation by having blown insulation installed. Both energy-saving upgrades can usually be completed in a single day.
