The American Window

Low E – glass windows are a great favorite for all contractors. They can be installed almost all the region but before taking Window Installation Service, you have to make sure about the building design and building position. Low-E windows can provide aesthetic value to building occupants, and they will not reduce the amount of light entering the building while maintaining the natural look of windows. However, windows can also represent a large source of heat gain or loss, because when the right window is not used, it can increase heating costs and A/C usage, making it more costly to operate your building. There are a few performance-based areas you have to consider while choosing that is most suitable for your local climate.

​

Lower Solar Heat Gain Coefficient (SHGC) is better that measures how well a product blocks heat from the sun from entering the building. It is usually expressed as a number between 0 and 1, with a lower SHGC indicating a product that is better at blocking unwanted heat gain.

​

Air Leakage measures how much outside air comes into a home or building through a product. AL rates typically fall in a range between 0.1 and 0.3, with a lower Air Leakage indicating a product that is better at keeping air out.

 Condensation Resistance is generally used to measures how well a product resists the formation of condensation. CR is expressed as a number between 1 and 100, with a higher CR indicating a product better able to resist condensation.

Low – E window Benefits and cost – They are typically cost about ten to fifteen percent more than regular windows but they reduce energy loss by as much as 30 percent to 50 percent. In case of Efficiency improvements to the building envelope directly impact the heating and cooling needs of the building; therefore, window systems should be adjusted accordingly to account for the system.
