Soffit air baffles air installed in a vented attic assembly to allow the attic to ventilate. They also hold the newly installed TruSoft cellulose insulation in place and keep it from being blown around in the attic.

Bath fans are used to exhaust hot/humid air from bathrooms to keep mold/mildew from growing in the bathroom. Sometimes they can also create air leakage around them as they don't fit the hole in the drywall during the installation. This before and after photo set shows the air leakage around a bath fan being sealed by a Comfenergy crew member.

Top wall plates allow heated air to escape from your home during something called the "stack effect".  This contributes to higher than necessary utility bills, draftiness in the home, and dusting too often. The following before/after pics show how Comfenergy seals these leaks using one part spray foam.
