Replacement Window Myths Homeowners Keep Falling For

Replacement Window Myths Homeowners Keep Falling For

Unless they’re broken, we don’t think about windows that often. They let in sunlight and heat.  They can let out, or keep in warmth when it is cold, and cool air when it is warm.  Having the right windows can lower utility bills and keep a home and its inhabitants comfortable.  When it is time to replace windows, there are myths that if a homeowner believes, they may end up with the wrong windows or spend too much money.

Myth #1:  Windows Need To Be Airtight 

Windows have vents on them which prove that they do not have to be airtight, in fact, windows need to breathe. With this knowledge in mind, windows should not be cleaned by spraying a garden hose up at the window from the ground, since water can get inside the window vents and not only lead to a mess inside, but also lead to problems with mildew which can eventually lead to other more serious problems.

Common signs of windows with clogged or plugged vents include:

  • Peeling paint around windows
  • Condensation on the inside of a window, or between windows on double pained glass windows
  • Mirrors that fog
  • Mildew

These are all signs that the windows in a home are not breathing properly.  Purchasing new windows that combat problems with mildew and condensation have a “condensation resistance” rating.  The ratings are generally between 0-100 with the higher number better as it relates to condensation resistance.

Myth #2:  Unbelievably Low Prices

The actual cost of windows should take into account how energy efficient they are. As a consumer, you want to learn to look past the upfront costs, and make sure you are getting a comprehensive understanding of overall costs. If it costs more to keep a home heated or cooled, then that is a cost that should be included in the cost of the windows.

Double pained windows and Low-e glass windows (windows with a microscopic layer of metallic oxides that are invisible to the naked eye) save money on utilities. This coating protects a home from UV rays which is not only harmful to skin, it fades carpets and can damage furniture.  Low-e windows keeps homes warmer in the winter by reflecting certain lights in the home, and cooler in the summer by reflecting certain light back outside.

Myth 3:  Heat Shrink Window Film Works Just As Well As Low-e Glass

Heat shrink film is an eye sore on a window, and often has air or other debris between the film and the window – that won’t allow the heat shrink film to help very much. Windows that are made to be energy efficient have a coating in between the panes that can lower the U-factor and reduce heat costs up to 50%. Triple pane windows offer even more energy savings because the windows are built with gases in between the panes that assist with insulation. Plastic over the window just doesn’t cut it as a way to keep cool air out efficiently.

Thanks to National Fenestration Rating Council, nearly all new windows come with a sticker that informs a buyer how that window is rated for energy efficiency.  One thing that it measures is the amount of solar heat gained coefficient, or SHGC and other measures to determine how much good heat is brought into the house, and how much bad light is reflected out.  This is a good way to evaluate how much energy a new window will cost once installed.

Myth 4:  The Windows Have A (FERC) Energy Performance Rating Sticker, Therefore, It Is Energy Efficient

Much of the information you need to make a good window purchase is on the NFRC sticker. The NFRC performance rating sticker simply means that the window has been rated; it does not mean it is energy efficient. For example, if you are interested in receiving a tax credit for installing the new windows, the NFRC rating should be equal to or less than .3, but even those with higher numbers will probably have the sticker.

An Energy Star sticker on a window indicates that the window meets the government standards for energy efficiency.  The NFRC sticker is useful, but just because it has a sticker does not mean it will be a good window for your home.

Myth 5:  All Window Frames Are Created Equal

The window frame can affect the overall efficiency of a window in several ways.

  • Aluminum windows are lighter and cheaper, but they conduct heat and are poor insulators;
  • Vinyl frames are the best.  They come with a UV stabilizer that prevents sun damage, and they have good thermal performance ratings.
  • Wood frames are good insulators, and they look great, but
    • If moisture gets in them, they will eventually rot, even cedar and treated lumber;
    • They must be caulked and sealed with gaskets.
    • Corners must be sealed.
    • Wooden frames must be checked often to ensure moisture does not get behind them or in them.

Myth 6: It Doesn’t Matter Who Installs The Windows

Even triple pained windows, some of the best available windows, will not do their job properly if they are not installed correctly.  A professional window installer understands how much space to leave so the window can be properly shimmed and insulated.

A professional insulator also understands how to make existing trim work, or if it will need to be replaced to get the most value from replacement windows.  The professional window installer can ensure that the window is installed correctly, and they will ensure that the window and the frame are properly insulated.
