Types of Window Styles to Choose From When Developing Home Construction Plans

By Mark J. Donovan

There are many different window styles to choose from when designing your new custom home or home addition. Window styles are often named by how they are open and closed. Common window types today include single and double hung windows, casement windows, skylight windows, bay windows and replacement windows, just to name a few. Today’s modern window styles also include single, double and even triple panes. Window style selection depends upon a couple of key factors; house design style, and local weather conditions.

Not all windows work with every house design and similarly not all windows work well for all types of weather conditions.

So it’s important aesthetically and functionally to select window styles that are right for the particular home and climate region.

Replacement windows are meant, as the name suggests, for replacing existing old windows. Replacement windows are designed to slide and mount into existing window frames. They are typically reasonably priced and provide a much better insulation factor than the original old windows.

Single and double hung windows are commonly installed in homes today. Double hung windows have top and bottom window sashes that can slide vertically up and down in the window frame. Single hung windows have only one moveable sash within the window frame. They have a nailing flange on the outside perimeter of the window that allows the window to be easily attached to the home.

There are also horizontal sliding sash windows that work effectively like the single and double hung windows.
There can be two or three sashes within these windows that can be horizontally slid in the window frame. If there are three sashes usually the center one is a fixed panel.

Casement windows have vertical or horizontal windows that crank open. Normally there are two or three horizontally or vertically mounted window sashes per casement window. If there is a third sash it is normally a fixed panel.

Tilt windows can be open inwards from either the top or bottom of the window.

Bay windows are comprised of three window sections that extend outward from the exterior house wall. The side sections have moveable sashes and the center window is a fixed panel. There is a large seating area with bay windows that is often used for displaying knick-knacks or plants. Bow windows are similar to bay windows except that they have typically 4 or more sections to give more of a rounder or bowed appearance.

Fixed windows, as their name suggests, cannot be opened. Transom windows, are a form of a fixed window. Transom windows are often seen above doorway entrances.

Picture or garden windows are usually large fixed windows. They are often used in kitchens, living rooms and family rooms.

Skylight windows mount in ceilings and can have fixed or moveable window sections. They can also come with integrated blinds and screens.
