Replacement Windows and Drafts In Your Home
Posted by James Desmond on Sun, Nov 08, 2009 @ 01:19 PM
Hello my fellow Home owners,
It's a lovely fall weekend in New England but we all know that it wont be long before the cold winter weather will be a pone us. This is the time to look at the thermal envelope of your home and make it as energy efficient as possible. HouseGuru will continue to post energy saving tips for your home and offer ways to help you conserve energy and save money.
The most important thing to be aware of now are the air leaks around your home. You can start by looking at your windows and doors since these are two of the areas that can lose energy to air infiltration. Remember the the energy tax rebate program ends December 31st where you can recieve a $1500 dollar tax credit from the government for Energy Efficient Replacement Windows that qualify for the program. One of the most efficient windows on the market that meet and exceed the programs qualifications are Heat Mirror Windows. 
More than any other time of year, you notice your home's air leaks in the winter. Most people call these air leaks "drafts." You may feel these drafts around windows and doors and think these leaks are your major source of wasted energy. In most homes, however, other significant air leaks are hidden in the attic and basement. These are leaks that also significantly raise your energy bill and make your house uncomfortable. But locating leaks can be difficult because they are often hidden under your insulation. In cold weather, warm air rises in your house, just like it does in a chimney. This air, which you have paid to heat, is just wasted as it rises up into your attic and sucks cold air in all around your home - around windows, doors, and through holes into the basement.
Common Household Air Leaks
* Behind Kneewalls
* Attic Hatch
* Wiring Holes
* Plumbing Vent
* Open Soffit (the box that hides the recessed lights)
* Recessed Light
* Furnace Flue or Duct Chaseway (the hollow box or wall feature that hides ducts)
* Basement Rim Joists (where the foundation meets the wood framing)
* Windows and Doors
Locating Basement Air Leaks
A common area of air leakage in the basement is along the top of the basement wall where cement or block comes in contact with the wood frame. These leaks can easily be fixed in portions of the basement that are unfinished. Since the top of the wall is above ground, outside air can be drawn in through cracks and gaps where the house framing sits on top of the foundation. This perimeter framing is called the rim (or band) joist. In the basement, the above floor joists end at the rim joist creating multiple cavities along the length of the wall, and many opportunities for leakage.
