<h2><p>Air-Sealing Priorities</p></h2>		
		Almost every house has a large number of hidden air leaks that rob it of heating and cooling energy. Although sealing these leaks is not the easiest job, it is one of the most cost-effective things you can do to increase your home’s energy efficiency. You’ll want to do this before adding any insulation, as fixing the leaks is much more difficult once extra insulation is installed. In addition to saving energy and making your home more comfortable, sealing air leaks also reduces ice dams and freezing pipes, and helps control moisture movement that can contribute to mold and structural damage. People often think that windows and doors are the source of most air leakage in a house, but the largest leaks are almost always hidden in attics, basements, crawlspaces, and other unexpected places.<p><a href="http://Sealing Air Leaks" target="_blank" rel="noopener">Sealing Air Leaks</a></p><p>Attic Air-Sealing</p><p>Basement/Crawlspace Air-Sealing</p><p>Sidewall Air-Sealing</p><p>Weatherstripping Doors and Hatches</p>Sealing Air Leaks<p>Identify the most important leaks first; sealing them makes the biggest difference in comfort and energy. The priorities are big leaks, and leaks at higher pressures. Air movement and leakage areas are not always intuitively clear, but remember that air does not move through most solid objects (concrete block and masonry in general are notable exceptions). Air leaks mostly through connections and spaces between building materials.</p>
