Before you call us, it is a good idea to do some basic window research.
What are energy efficient Windows?
The National Fenestration Rating Council (NFRC) label must be installed on the window before it can be called an "energy-efficient window". The Council is a non-profit organization who establishes objective window energy performance ratings to help consumers like you compare products and make informed purchase decisions. What many people don't realize is, what is classified as energy efficient in Arizona or New Mexico may not be as energy efficient in Michigan. To better understand this, you will need to know what the NFRC measures.
SHGC stands for Solar Heat Gain Coefficient. This means the ability of the window unit to reflect the sun's infrared rays. If you want to minimize over heating in your home, then you will be looking for a double or triple pane unit that has a low SHGC value. You may also want to have a low value for your south facing window units.
This factor is all about how well the replacement window is going to be as insulation to the outside elements or how well the window keeps the heat in. This will be important for homes in Michigan. The U-Factor is expressed in numbers 0.20 to 1.20 and the lower the number, the better the insulation factor.
It is a fact that most new and replacement windows are not air tight. The NFRC measures and quantifies the amount of air that could pass through the gaps around the window units. The scale ranges from 0.1 to 0.3. Look for window units that have a lower "Air Leakage" value since they are better at keeping unwanted drafts to a minimum.
Visible Transmittance deals with the sunshine. Visible transmittance will determine how much natural light that could come through the window. If your room is dark or faces north, you may want a higher value. South facing rooms may need to consider the fact that excessive sunlight can fade rugs, drapes and furniture. Therefore for south facing rooms, you may consider a lower value.
The next thing you will want to do is take inventory of your existing home or office windows that you will be replacing. Measure the height and width of each window. Are they installed on the north, west, east or south facing walls. This is important to know so that you can select the double or triple pane units that will provide the best ROI for you.
There are many styles of window such as Bay Windows, Bow Windows, Casement Windows, Double Hung Windows, Glider Windows, Polygon Windows, just to mention a few. Some are acceptable for first floor installations while others are better suited for second and third floor situations. There also exists and vast array of materials of construct starting from wooden frames to vinyl, fiberglass, aluminum and more. Don't forget to also consider the color of the window frames. Selecting the right color can greatly enhance the appearance and value of your home. When you go to sell your property, tastefully selected colors will increase your "curb appeal" and may fetch you a higher bidding offer.
