Four Basic Replacement Window Styles

Double or Single Hung Windows

The most popular style of window is the double hung window.  This style is traditional with the window opening up and down or vertically.  Each glass unit is set into a framework called a sash, on a double hung window both the upper and the bottom sash move.  Being able to open either the top or the bottom for air circulation gives the homeowner more options in creating comfort within our homes.  A single hung window has a stationary top sash with only the bottom sash able to move or open.  Screens are place on the outside of the window.

Sliding Windows

Sliding windows have two sashes as well, but they move horizontally or from side to side.  As with a double hung or single hung window, sliding windows come in a double sliding or single sliding.  In a double sliding window, both sashes move, again allowing for better air circulation.  On a single sliding window, one side is stationary or permanently fixed.  Screens are placed on the outside of the window.

Casement Windows

Casement windows are hinged on one vertical side of the window and opens out.  They can either be opened with a crank or be pushed out with an arm.  The screens are place on the inside of the window as the movement of the window outward inhibits a screen on the outside.  A casement window can catch breezes, improving the air circulation within your home.

Awning Windows

An awning window is hinged on the top horizontal side of the window and opens out.  The screens are placed on the inside, again because of the way the window operates.  An awning window can be opened during a light rain as it opens like an awning to protect the opening.

Each window style operates a bit different and looks different.  No one window will suit every application and sometimes a combination of window styles works best.  When replacing your current windows, consider looking at different window styles to see what will work best for your home.
