Renewal by Andersen Bow & Bay Windows
Give your home the appearance of having undergone a major remodel without the cost. Choose bow & bay replacement windows from Renewal by Andersen® of Knoxville. Our experienced design consultants will work with you to design bow or bay windows that will add a beautiful new feature to the exterior of your home, helping to make it the talk of the neighborhood.
Bow & bay windows are two distinct, but similar, styles. Here is a brief look at the differences between the two:
Bow windows, as their named suggests, extend from the exterior walls of your home in a gently arched shape. They consist of four or more window panels, often utilizing double hung or casement windows.
Bay Windows
Bay windows are more linear than bow windows and consist of three window panels. Like bow windows they extend from the exterior walls of your home, but unlike bow windows they are more angular rather than a gentle curve.
Whether you choose bow or bay windows, you will be able to choose from a wide selection of window styles that will make up the window panels. We offer a full selection of traditional and specialty replacement windows for Knoxville area homeowners to choose from when designing their bow & bay windows.
With multiple window panels, there may be the concern that maintenance will be difficult and that energy efficiency may be a problem. But when you choose Renewal by Andersen window replacement, you will enjoy many years of indoor comfort, low-maintenance, and energy efficiency.
Bow & bay windows will dramatically change the exterior appearance of your home, at a fraction of the cost of major renovations.
