A bow window unit also projects outward from the wall of the house. The bow may contain from three to six window units which will all be equal in size. Although each window is straight the bow unit will form a curve. Ventilating casement units are typically selected, sometimes along with non-operating picture window units.
You may have an old bow or bay window that needs to be replaced. Also, any picture window is a great location for a new bow. The new projecting unit is custom-made and will not require costly and time-consuming structural changes. It will add new dimension to the room and the exterior of the home. It can be tied into an overhang or installed with an optional roof assembly.

There is only one reliable way to compare windows and that is by asking for the NFRC* rating for each window that you are considering. NFRC labels are independently certified and rate the whole window performance by U-Factor and Solar Heat Gain Coefficient (SHGC). The lower these ratings are the better the window will perform. The priority of U-Factor versus SHGC depends on your climate. You should ignore all the sales hype and choose the best NFRC ratings for your climate at the best cost.
Energy Star is a window certification program administered by the Federal Government to help you select energy efficient windows optimized for your climate. A window must meet minimum performance criteria to qualify. These criteria are based on NFRC whole window performance ratings and are different for each of four climate zones as follows:
Northern Zone (blue): U-Factor of .30 or less, SHGC any
North Central Zone (yellow): U-Factor of .32 or less, SHGC of .40 or less
South Central Zone (orange): U-Factor of .35 or less, SHGC of .30 or less
Southern Zone (red): U-Factor of .60 or less, SHGC of .27 or less
Yes, any window or patio door ordered with a LowE glass upgrade will qualify for the Energy Star guidelines for the climate zone where purchased. This guarantee always comes in writing on your contract specifications so you will be assured of ordering and receiving the best LowE glass that is optimized for your particular climate zone.
Yes, you may be eligible to receive a 10% federal tax credit up to $200 for windows and $500 for doors that meet Energy Star guidelines. These credits had expired in 2011 but the new law, “The American Taxpayer Relief Act of 2012” has extended these tax credits to the end of 2013 and retroactively for 2012.

Positive: Quality, Responsiveness, Value
super professional installation process, great sales process, these guys really know what they’re doing. Good communication through the whole process and they were done sooner than they told us. Whole house full of replacements and we couldn’t be happier, highly recommend for any size project. When they say and easy, no pressure sales process, they mean it.


Aaron priced us triple pane high efficiency windows for the same price as basic, lower quality double panes from other companies. Installation was quick and communication good throughout the process. I’d recommend them for any window needs!
