What Do the Energy Ratings on Windows Mean?
If you are a customer looking at new windows for your home, you may have noticed all of the energy efficiency ratings. Our team of professionals can help you understand the ratings of energy saving windows. The ratings are:
» The U-factor: Between .20 and 1.20. This value rates heat loss from a building. A lower value means better insulation and higher resistance to heat flowing in or out of the home.
» The SHGC: Between 0 and 1, it stands for the solar heat gain coefficient. The lower the number the better, because it shows how much heat from the sun is blocked.
» VT: Between 0 and 1, it stands for visible transmittance. A higher number means more visible light through the window.
» AL: Stands for air leakage. A lower number means less air passing through the window area.
We can help you decipher these ratings to choose the right type of energy saving window treatments for your home. There is not one simple choice of energy efficient windows for every home because factors like the direction the home faces influence the right choice for a space.
