  7. 7. Reducing Air Leakage Your logo here TEST IN CFM AIR SEALING HOUSE TEST OUT CFM Air sealing is typically the most cost effective improvement you can make to your home. To properly seal out air leaks, a large fan called a blower door is used to depressurize your house. This makes air leaks easy to find, so corrective measures can be taken. A good air sealing job will dramatically increase the comfort of your home and help you save significant energy. 966 CFM REDUCTION reduced air changes per hour by 30%
  8. 8.  You’re sitting at home on your couch and you feel a draft of cold air. The first thing that might come to mind as the problem is your windows, but what if the issue is bigger than that?  Your house is a system of parts that interact with each other. Therefore, your issue could be partially related to your windows, but more likely your home may be under-insulated or warm air is escaping through cracks and gaps that you cannot see. This is where a home energy audit comes into play. › Priority #1: Attic air sealing  Top plates, wire penetrations, plumbing penetrations, recessed lights, attic access points. › Priority #2: Basement and/or crawlspace air sealing  Plumbing and electrical bypasses in the basement or crawlspace ceiling, rim joist, and sill plate areas. › Priority #3: Penetrations inside the living space on the outside facing walls  Plumbing and electrical bypasses underneath sinks and other areas  Caulking windows and doors  Weather-stripping and door sweep replacements.
