At Hoosier Square, we strive to seal out the wind, and keep in the heat. 

Unplanned air infiltration into houses is the number one reason people feel cold and use more energy.  In most cases the second reason people use more energy in their homes, is that they are VASTLY UNDERINSULATED IN THE ATTIC.  Most older homes we inspect AT BEST have an R-19 in the attic.  This is less than 1/2 what both the State and Federal Government recommends.  General Note:  Those US Government recommendations are based on AUGUST 1998 energy costs.

Drill out your hole, then measure the space between studs, both sideways and up and down.  This is VERY IMPORTANT. Many older homes' framing are not spaced on a standard 16" stud spacing, not to mention bracing, fire blocking, window weight pockets, and a host of other spaces that create "cold wind pass throughs" in your walls.  The more of these that are blocked and filled, the better to reduce overall air infiltration into the house.

Next you push the hose all the way up in the cavity.  The hose, also known as an elephant nose, it only about 1 1/4" in diameter, having been reduced down from 2" or bigger.  The reason we do this, is so we can get a hose in tight spaces and fill the walls, which results in a density of about 3 pounds per cubic foot of insulation.  This also is about the same density used when we "spray fill" open walls on new homes.  By working the hose slowly in and out of the cavity, while listening for the blower to "bog down due to back pressure", we are able to consistantly get good results and seal up older homes.

It is a time consuming process, but well worth the cost, in energy savings, and comfort level. For more information on this aspect, you can click here: ENERGY SAVINGS . In some cases, we can even "REPACK" older homes that have had poor or shoddy work done on the insides of their walls.  That is, we can fill up old walls that had THIN R-8 fiberglass batts installed, like the old NATIONAL HOMES, or fill in walls that someone else had "LOOSE PACKED" 20 years ago.  The following pictures show what happens when you insert the hose into the walls to fill them. 

On older homes that we "drill and blow", we take a sample of the wood with the paint on it, to the local paint store and have them color match it.  We then paint the "plugs" to match.  On some homes, we can remove the siding and drill behind it, but this is on a case by case basis.  These two pictures show the finished exterior of the house that we were filling in the above pictures.
