Dr. Energy Saver St. Louis Case Studies: Air Sealing in St. Charles, MO

Wednesday, June 18th, 2014 by Rachel Sipes


The back room in Michel B’s house would always become drafty in the winter and extra hot in the summer.  Comfort in the house wasn’t a perfect 10 because of this one room.  Often times they would put fans in the back room during the summer and space heaters in their bed rooms in the winter.  These fluctuations in the air wasn’t good and because of this issue they house started to develop a musty odor that did not agree with the family member who had asthma.  Michel had made the call to Dr. Energy Saver to get his house diagnosed.  Contractor Jake Hurst came and checked the entire house and proposed Michel his solution to this recurring problem.


Dr. Energy Saver first sealed the spaces in the attic and through out the house with foam to stop exfiltration of conditioned air into the attic and to improve the quality of the air inside.  They then installed a blow loose-fill cellulose insulation in the attic to improve thermal boundary between the attic and conditioned space.  A dam was installed to air seal around high temperature penetration in order to allow insulation around that penetration.  A roof vent to reduce humidity in the home and several bathroom fans to move exhausted air outside the attic.
