Considering replacing your current windows? There is a lot to consider before making such a large investment in your home. It is important to understand that not all window glasses are made the same. Based on the Department of Energy, the glazing technology of windows has become far more sophisticated than before. 

Homeowners should consider factors such as the design of their home as well as the climate of the area of the country they live in when selecting the correct glazing for their windows to maximize energy efficiency. Below are the most common types of window glazing available. 

1. Gas Fills: Argon, krypton or other inert gases are used to fill in spaces between the panes of glass, creating a lower U-factor. This is the most typical glazed used for colder areas in the U.S. For windows in the Howard County Maryland and surrounding areas, you are looking for a U-Factor of 0.30 or less.

2. Heat-Absorbing Tints: There are many varieties of window tint colors, yet the most common is typically gray-bronzed. They help to reduce the heat and glare from the sun. The green and blue tints will allow for more daylight to penetrate through and only slightly reduce the amount of heat transferred. 

3. Low-E Coatings: This type of coating will cost more (10% to 15% more). It is a worthwhile investment because of the energy loss reduction of 30% to 50%! 

4. Reflective Coatings: This glazing can cut out a whopping 40%-70% of solar heat while also reducing a window’s SHGC (Solar Heat Gain Coefficient). For homes and businesses in Maryland, you are looking for an SHGC of 0.40 or less. 

Armed with this information, you should now have a better understanding of what you are looking for when considering replacing your windows to maximize the energy efficiency and reduction of heating and cooling costs. Design and appearance should not be the only factors you consider. It stands to be said that even if you select the most efficient windows for your area, if they are not installed correctly, they will not perform properly and you will experience energy loss and possible water leakage. It is always recommended to hire a window professional for installation. Give us a call today for a free, no-obligation consultation at 1-800-673-3034.
