Understand the Efficiency of Vinyl Windows
Vinyl windows can have a huge effect on the energy efficiency of your home. In order to make it through the hot summers in Camarillo, CA in comfort, you need windows that are doing a good job. If you are looking into new vinyl windows, it is important to understand the rating system used for windows. Do your homework in advance so when the windows are sitting in front of you, you will be able to tell which one is the best efficiency choice. Here are some of the ratings you will see on vinyl windows and what they mean.
U-Factor
The U-factor is the rating that tells you how well the window will keep the heat or air conditioned air inside your home. You want to see a low number here because lower numbers indicate a window that is better at insulating the home. The typical numbers range between .20 and 1.20. The lower the number, the better the window.
Solar Heat Gain Coefficient
The SHGC measures the window’s ability to block radiant heat that comes into your home from the sun. When you live in Camarillo, CA, heat from the sun can be significant! You also want to see a lower number here. The rating will show anywhere between 0 and 1. The lower the number, the less heat you will feel in your house from the sun.
Air Leakage
Manufacturers sometimes include this optional rating and it is an important number when you see it. This rating lets you know how much energy you lose or gain through the hardware in the window. You want to see a low number here too because it will indicate that less air can pass through those openings.
Visible Transmittance
The VT on the window is the amount of visible light that is transmitted from outside to inside your home through the window. You put windows in your house because you want to see out and because you want natural light to come in. So you want this number to be high. Just because you have a high VT does not mean you will increase your SHGC. Energy efficiency windows often have glazing on them that prevent the heat, but allow the light.
