Andersen Windows has a cool new thingamjiggy on its website, a style library that helps you envision the kind of windows and doors you want when remodeling or building a home. The Andersen Home Style Library shows a collection of distinct, historic architectural styles from Federal to Queeen Anne to Prairie. You can look at architectural renderings of homes with various styles of windows, as well as read a quick history of the style and find out what mix and match options are available.
The site also features photos of windows and provides pointers on creating a style or mix of styles, maximizing a view, and letting in light. The company's A-Series windows have common sight lights, glass setbacks, and profiles, so they can be mixed and matched with various architectural styles.
For example, here is a library with Georgian Federal windows, which have multiple divided lights and rectangular grilles.
Here are two views of a home with a blended style rooted in Craftsman Bungalow; its windows have grille patterns that create vertical proportions.
