What Are Double Hung Windows?

A double hung replacement window is a window that features an upper and lower window sash that slide vertically past one another in a single casement. Perhaps one of the most traditional styles of windows, this type of window typically features the lower sash in front of the upper sash. Each sash may be a solid pane of glass or may be divided into separate lights by built-in muntins or for decorative purposes, may have a snap-in, removable grid to create the illusion of separate lights. Replacement double-hung windows are designed with two grooves in the side jambs that allow each window sash to slide separate from one another. Some have a full window screen, allowing for ventilation from the top or bottom of the window at any time, while others have only a half-screen that needs be positioned accordingly. The ability to have a ventilation area equal to half of the window’s total area is one reason the double-hung design is so widely used.

Our collection of replacement double hung windows ares especially valued for their versatility. Some of the features that modern double-hung windows have include insulation for improved energy efficiency, tilt-in sashes that make cleaning the outside of the window easy, and UV protection.

Advantages of Double Hung Windows

There are many, many advantages to using our double hung windows for your Houston window replacement project. In addition to versatility, double-hung windows are also stylish. They are available in vinyl and wood casements and additional features, such as transoms, can be used with them. Additionally, a double-hung window can be arranged in different ways. Single window units can replace a worn out or dysfunctional window. In groups of three or more, double-hung windows fill larger wall space while maintaining the ventilation and versatility that are lacking in a picture window. While replacement windows of any kind will add value to a property, a double-hung window is almost a guaranteed value because it is both a stylish and functioning window.

Ease of Cleaning

Most contemporary double hung windows are developed for ease of cleaning. Since both sashes tilt in, it means you can clean the outside of the windows from the inside—eliminating the hassle and danger of climbing ladders and scaffolding or using long-handled tools. You can quickly make your windows look bright and new without leaving your home or working up a sweat.

Energy Efficiency

Installing double hung windows in your new or existing property has many advantages when it comes to energy efficiency. New double hung windows can drastically reduce heating and cooling costs due to increased energy efficiency. Old windows are inherently inefficient because they were not designed with energy efficiency in mind—even windows that are more than 10 years old. In addition, joints may have loosened or rotted over the years, increasing the amount of air infiltration into your home. Replacing old windows with new double hung models will reduce HVAC expenses, reduce energy loss, and improve the comfort of your home.

Cooling Benefits

Double hung windows have an advantage for homeowners looking to install window AC units. Since the sashes move up and down, an air conditioner can easily be placed and secured in place in the window.


Because the window sashes on double hung models move up and down, you have to put a screen on the window. Unlike awning or casement windows that open out, having a screen installed allows you to let a breeze in without bugs or other debris.
