The Blower Door Test is attached to the frame on the front door and used to create a controlled environment in the home to reveal possible air leakage.
This is a nice looking attic, however many of the problems occurring in the home lie beneath this floor. In order to properly seal the home the floor and the insulation need to be removed.
Here you can see where the home changes levels. The vertical walls between the two floors are often left uninsulated.
The second part of the attic revealed quite a bit of air leakage during the Energy Audit.
Here is a look at what is underneath the attic floor.
Once we started removing the floor, we were able to access the "problem" spots where air and insulation were being pulled into the home.
You cannot avoid cutting holes in order to run wires throughout the home. However, once the wires are ran the holes still need to be sealed!
Looking at this picture, you might not be able to tell that there is an empty cavity allowing a lot of air to flow into the home.
Once the insulation was removed, it is easier to see the open cavity. The only barrier between this cavity and inside the home is drywall.
We use bathroom fans to get moisture out of the house. However this fan is not properly ventilated and is releasing all that moisture into the attic space!
The attic insulation is removed in order to properly air seal all open cavities, cracks, and gaps.
Removing blown-in insulation from the attic you are able to clearly see cracks and gaps that air not only allowing air to flow through them, but insulation as well.
The gaps and cracks around the flooring and wires were air sealed tight using expanding spray foam.
Blown-in insulation has been removed and we are ready to air seal!
The gaps between the attic wall and floor were sealed with expanding spray foam.
Blown-in insulation has been removed and Expanding Spray foam is installed to air seal all gaps and cracks. Insulation will be blown over the top.
This is a good side-by-side to compare the vertical wall before and after insulation.
Silverglo and Expanding Spray Foam was installed over the vertical wall between the two floors in the attic.
Now that the attic has been properly air sealed, insulation is blown-in over the top.
Duct Tape was originally used to seal up the duct work in order to prevent air from leaking through, however it needs to be properly sealed.
The Duct Tape was removed and the ducts were properly air sealed using Aeroseal.
This dirty crawl space is about to receive a makeover!
You will see a lot of crawlspaces insulated in this manner, however, by installing CleanSpace Crawlspace Encapsulation we have the advantage of air sealing and insulating at the source (the ground) making this type of insulation useless.
The duct work is lying on the cold ground, which is why we insulate crawlspaces at the source!
Fiberglass insulation has been removed and CleanSpace is ready to be installed!
Clean Space Crawl Encapsulation is being installed on the floor and up the walls to provide protection against air leakage, unwanted pests, and moisture.
The area looks much cleaner!
Dust was a major problem throughout this Indianapolis, IN home. An Energy Audit was performed to determine where the dust was coming from. A blower door test revealed that there was not only air leaking into the home, but insulation from the attic was being pulled in as well! This meant that the family's dust problem wasn't really a dust problem at all, it was insulation!
