Years ago, the most common type of home window had a side hinge and swung in or out when opened. With advancements in window design, mechanisms were developed to make opening windows easier and with more options. Today, the double hung window is by far the most popular style of replacement window.
Double hung windows consist of two sashes that slide up and down to open independently of each other. You can either slide the bottom sash up or the top sash down. This is a desirable safety feature if you have small children or pets that can reach the bottom portion of the window. Double hung windows are easy to clean, especially those designed with a sash tilt-in feature. Double hung windows complement many different styles of architecture, from traditional to modern.
But there's a variety of other window styles available. When undertaking a replacement window project, consider other styles, even if you currently have double hung windows. Work with your replacement window professional to decide which design will work best with your home.
Casement windows: These windows are hinged at the side and open with a crank. When closed they create a tight seal, making them very energy efficient. When choosing this style of window, you must take into account any obstructions on the exterior side of the window that might hinder fully opening the window.
Slider windows: Sliders are similar to a double hung window turned on its side. Where double hung window sashes slide up and down, slider window sashes open from side to side. Slider windows are comparable to double hung windows when it comes to energy efficiency.
Picture windows: A picture window is fixed, meaning it does not open. This style allows the most daylight to enter a room and provides sweeping views of the outdoors. Picture windows are often used for very large windows or where the need to open them isn't an issue, such as in a two-story foyer or in a room with vaulted ceilings.
Awning and hopper windows: This style of window opens via a hinge rather than sliding. Awning windows are hinged at the top and open outwards, while hopper windows are hinged at the bottom and tilt in. Awning windows have many applications including the kitchen and bathroom. Hopper windows are most commonly seen in basements.
Bay and bow windows: Often the focal point of a room, bay and bow windows up the "wow factor" of any room. They make a room appear larger because they protrude out from the home's exterior while allowing in plenty of light and sweeping views. Bay windows are typically comprised of a center picture window with a casement or double hung window on either side. A bow window setup contains four or more windows that can either be vented or fixed. Styles used for a bow window configuration can include double hung or casement windows.
