While it’s well-known that homes require insulation to mitigate heat loss through walls, ceilings and floors, the concept of air sealing is often less understood. Yet, its been stated, “one third of the energy you pay for probably leaks through holes in your house.”
Air leaks occur when outside air enters and conditioned air leaves your house uncontrollably through cracks and openings. In addition to wasting energy, air leaks may contribute to moisture problems, and poor indoor air quality.
Air sealing will save you money on heating and cooling costs, improve system longevity, and increase occupant comfort. It will also help to create a healthier indoor environment. Air sealing doesn’t require much effort, and is generally very cost-productive.
Air Sealing Measures
Some measures you can do yourself include In CT:
Caulking around windows and doors
Installing foam gaskets behind outlet and switch plates
Installing weatherstripping around windows and doors (include the garage door)
Replacing door bottoms (thresholds) with those that feature pliable gaskets
Other sources of air leaks, such as attic and lighting fixture penetrations, are best addressed by a professional. Before beginning any of these measures, it is a good idea to have a comprehensive energy audit performed, which includes both a visual inspection and thermal imaging scan. An energy audit can detect cold spots, air leaks and intrusion, energy-hogging appliances, and insufficient insulation levels.
Save with Energy Upgrade Rebates
Good news! There are several energy upgrade rebates available that make air sealing substantially more affordable. Eligible homeowners can recoup a large sum of their project costs. Call Connecticut Retrofit at 860.238.3112 or visit us online at ctretrofit.com
