There are many different procedures to weatherize your home. Some of the more common weatherization items are:
Duct-work: Poorly sealed duct-work can account for 20% of heat loss. By sealing supply and return air ducts, you can greatly improve a home’s efficiency by keeping conditioned air in the home. A mastic type product is used to properly seal old duct-work to make them air tight. Duct tape is not used since it is not suitable for this purpose.
Cracks, Gaps & Holes: In older homes, there are many places for air and water to leak in. This is especially true around doors, windows, pipes and wiring that penetrate the ceiling and floor. Depending on the size of the penetration or crack, products like spray foam, caulk, weather-stripping, door sweeps, and so on, can be used to help minimize infiltration.
Insulation: Proper insulation is necessary in walls, floors, and ceilings. Depending on the construction type and what is trying to be accomplished, both blown in type insulation and fiberglass batts can be used.
Recess Light Fixtures: These types of light fixtures, which are also called can lights or high-hats, leak large amounts of conditioned air into unconditioned attic space and also allow hot attic air to enter the home. It is necessary to air seal recessed lighting fixtures.
Water Heaters: Protect water heaters and pipes from corrosion and freezing. Install insulation jackets to water heaters that are located outside of conditioned space.
Fan Dampers: Install or replace dampers in exhaust ducts to prevent outside air from entering the house when the exhaust fan or clothes dryer is not in use.
Moisture Barriers & Flashing: Depending on the situation, install crawlspace moisture barriers, repair roofs, fix flashing or replace skylights and solar tubes.
Entry Doors & Windows: Depending on the situation, and the home construction, installing storm doors and storm windows and also new entry doors and windows can be beneficial.
HVAC Systems: Updating split systems with package units and re-do associated duct-work as needed.
