Why Double-Hung Windows?

Double hung windows are perfect for most traditional American homes including: cape cods, colonials, Victorians, craftsman homes, ranch homes, cottages, farmhouses, or tudors.

Depending on the style of your home, consider a grid pattern for your double hung windows, which would give them an added custom touch and the opportunity to completely transform your home’s curb appeal.

Tip: How to evaluate energy efficiency in windows

Selecting windows for your new home or replacing your existing windows is a big undertaking. With so many different terms and rating systems, it can be hard to know which windows are truly the most efficient. Here’s what to look for:


When it comes to selecting the type of glass for your windows, look for Low-E and Gas Fill. Low-E means the glass will reflect infrared light, keeping your home warm in the winter and cool in the summer. Gas Fill means the window is insulated with Argon or Krypton between the panes.


For best energy efficiency, consider a vinyl or wooden frame. Note that wooden frames will need more maintenance than a vinyl frame (painting, staining, etc.). Aluminum frames on the other hand, are the least efficient.


Look for ENERGY STAR certified windows. These windows have had efficiency of their glass, gas, spacer and reinforcement evaluated. To become ENERGY STAR certified, the window’s U-factor and Solar Heat Gain Coefficient must be less than or equal to ENERGY STAR’s standards.

U-factor measures the amount of heat transferred through the window, or in other words, how well insulated it is. A window with a low U-factor is more energy efficient. Solar Heat Gain Coefficient is a measure of how much solar heat the windows allow into the house.
