At Egg Energy Systems our skilled installers are trained to perform the following examples of typical weatherization procedures:
- Sealing recessed lighting fixtures (‘can lights’ or ‘high-hats’), which leak large amounts of air into unconditioned attic space.
- Sealing air ducts, which can account for 20% of heat loss, using fiber-reinforced mastic (not duck/duct tape, which is not suitable for this purpose)
- Installing/replacing dampers in exhaust ducts, to prevent outside air from entering the house when the exhaust fan or clothes dryer is not in use.
- Protecting pipes from corrosion and freezing.
- Providing proper ventilation to unconditioned spaces to protect a building from the effects of condensation.
- Installing roofing, building wrap, siding, flashing, skylights or solar tubes and making sure they are in good condition on an existing building.
- Installing insulation in walls, floors, and ceilings, around ducts and pipes, around water heaters, and near the foundation and sill.
- Replacing old drafty doors with tightly sealing, insulated entry doors.
- Replacing older windows with high efficiency replacement windows.
The phrase “whole-house weatherization” extends the traditional definition of weatherization to include installation of modern, energy-saving heating and cooling equipment, or repair of old, inefficient equipment (furnaces, boilers, water heaters, programmable thermostats, air conditioners, and so on). The “Whole-House” approach also looks at how the house performs as a system.
