Air Sealing and Insulation
Air sealing and adding insulation are two of the most cost-effective steps you can take to improve the comfort and energy efficiency of your home. Doing one without the other decreases the overall energy efficiency effectiveness.
When air sealing and insulation work in concert, homeowners experience fewer drafts and have more comfortable rooms. Their homes are cleaner which creates an overall healthier environment and results in a quieter, more enjoyable home for everyone.
Benefits of Air Sealing
Gaps or cracks in a building’s exterior envelope and ‘holes’ in the attic floor can contribute to year-round energy waste by allowing conditioned air (heating or cooling) to leak outside and unconditioned air to seep in. The main culprits of air leaks are all around your home including:
- Windows and doors
- Recessed lights
- Electrical and wiring boxes
- Outdoor faucets
- Attic hatches
Besides the loss of energy, these openings are also an open invitation to pollutants, bugs and insects, rodents, noise and unwanted and harmful moisture, mold and mildew issues.
Insulating your home is one of the most basic steps you can take to reduce your energy costs and achieve year-round comfort. Most older homes (and newer homes, too) can benefit from additional insulation in the attic, exterior walls, overhangs, sill boxes or the foundation.
Industry experts agree it is important that your home breathes. Vapor barriers and industry standards for insulation and air sealing have improved over the years, but sometimes it is not enough. Typical areas in the home that could benefit from insulation include:
- Exterior walls
- Sill boxes
To understand how your home functions as a system, experts agree that you should hire a professional to conduct a Home Energy Audit. During the audit, your energy advisor will visually inspect your home and perform diagnostic tests to understand your home’s current eco-system BEFORE making any changes that might negatively affect another area of your home.
If you are replacing windows to cosmetically enhance the appearance of your home, there are plenty of fine choices for you to choose from. However, if you think your windows need to be replaced for increased energy efficiency, call us first. The problem may not be windows. You may need nothing more than air sealing and/or a different type of window treatment. We may be able to save you a bundle of cash.
