The Windows of Your Home

Depending on how you view your windows, they can be a blessing or a curse. Having as much natural light entering your home is not only healthy, but can save on lighting costs. Being able to open your windows to let in fresh air is also healthy and can save on heating and cooling costs. Unfortunately, windows are also very poor insulators and can cost the homeowner thousands of dollars over the lifetime of the home.

Some of the Science Behind Windows

Windows are measured on four main criteria:
  • Thermal performance data is governed by an agency called the NFRC. Windows use a value called U-factor which simply stated is the reciprocal of the R-value. In other words, if the U-value (or factor) is 0.50 the one divided by 0.50 is a 2.00 R-value. When you consider that the walls of your home are probably an R-11 or R-13, it is plain to see that glass is a poor insulator.
  • Solar Heat Gain Coefficient is a measurement of how much of the sun's heat energy is blocked by the glass. In some cases this is good (Southwest summers for instance) but in some cases it is bad (Northern winters for instance).
  • Air infiltration data is measured as the cubic feet of air per minute divided by the total sq/ft with a 25 mph wind (or 1.57 psf). Simply put, the lower the number, the better.
  • Structural performance is measured by putting the window under extreme pressure loads and measuring how much the components deflect (or bend). Another part of this test is determining at what point water begins to penetrate through the window frame system.
