Measuring The Energy Efficiency Of Your Windows

One of the greatest ways you can lose money for energy is through the windows of your home or business. While many people are aware of how warm and cool air can go through window glass, many are not aware of how this transference is measured by professional window installers. If you wonder whether your windows are costing you more in energy losses, finding out more about window energy efficiency measurements can help.

Determining U-Values Helps Determine Energy Loss

Knowing precisely how much heat is making through the glass of your windows is possible and is measured by a number called the U-value, also called by some professionals the U-factor. U-values are usually listed between 0.25 and 1.25 BTU/H feet squared at a Fahrenheit temperature. U-value measurements closest to 0.25 are the most acceptable, meaning you are not losing a great deal of energy through your window glass.

Condensation On Your Windows: Good Or Bad Sign?

If you find condensation forming on the inside of your windows, you can bet the humidity levels in your home or business is high. However, does condensation signify greater energy loss as well? Most window replacement and repair professionals say no. Because of the many people wondering and asking window manufacturers about condensation issues, the Condensation Resistance Factor rating system was created. Measurements for this rating system range between 30 and 80, the lowest numbers meaning a window produces less condensation. Maintaining an average humidity level in your home or business can help to reduce condensation.

Open The Blinds And Let The Light In

Visible transmittance describes the amount of light a window glass allows into a structure. Many people find opening their blinds and allowing light in is refreshing and it also allows greater heat inside during cold weather. The higher your visible transmittance (VT) rating is, the more light is being allowed in through a window pane. Most VT ratings range between 0 and 1, but windows with more than one pane can be higher, ranging between.30 and .70.

Increasing Your Energy Savings

Replacing old windows or repairing them can help you reach the best ratings for energy efficiency. If you live in an older home, consider the savings you can experience in the future by replacing old, wood frame windows with new vinyl style windows. The same is also true about your place of business. An old office building or warehouse with older style windows can cost you money, a cut into your total profits that is unnecessary and preventable with professional window repair or replacement by companies like Gary D Torgerson Co.
