Spray foam in Troy,IL

The detail between the foundation wall, the sill plate, the rim joist, and the sub flooring allows for significant air leakage from the outside...especially when pipe wire penetrations are added. It is also this rim joist area that is often poorly insulated. Even when your rim joist is insulated with fiberglass bats, the outside air will still leak in through the bats, because this form of insulation acts as a filter. Spraying expanding foam insulation on the inside surface of the rim joist, to cover the sill plate down to the top of the basement wall, not only seals all air leaks very effectively, but it insulates as well.

When ductwork or air handlers are located in an attic, they have to work much harder to keep your home comfortable. Battling temperatures upwards of 140 degrees F in the summer and as low as 30 degrees F or less in the winter, your attic air handlers need all the help they can get keeping your conditioned air the temperature you want it to be! One of the steps to achieving that is having your ductwork and air handlers sealed. Dr. Energy Saver encased this ductwork junction with spray foam insulation to seal any leaks, keeping that conditioned air traveling to where it needs to be---inside your living space!

This Troy,IL home wanted to make thier master bathroom more comfortable and improve the air quality in the home.  Dr. Energy Saver sprayed the cantilever to elimate any draft going into the master bath.  The attic was air sealed as well as the can lights.  The knee wall in the attic was sprayed with 2 part spray foam and coated with a fire resistant material.  This home now has a comfortable master bath and a very improved air quality throughout the home.

Job Stories From Troy, IL
Improving Efficiency of this Troy, IL Home

Tom and Norma have been living in their house for seven years and were interested in making some changes.  They wanted to improve efficiency of the home, so they called Dr. Energy Saver St. Louis.  They spray foamed and air sealed the rim joist to reduce air infiltration and to improve air quality.  They also got EverLast Basement Windows and Window Inserts.  These would help reduce air leakage and improve energy efficiency of the windown.  Now this couple's home is better suited for their needs.

Stop Condensation in this Eoliq, MO Home
