What is a Double-Hung Window?

The most commonly used vinyl replacement window in the USA today is a double-hung window. If you’re looking for timeless elegance and practicality, double-hung windows are for you. The classic design of double-hung windows complements any architectural style, making them a popular choice for homeowners seeking both functionality and aesthetics.

Double-hung windows get their name from the double set of sashes that traditionally were hung from counterweights inside the window frame. The counterweights allowed the sashes to be lifted or raised with less effort. They also allowed the sash to stay in position while raised.

Today, double-hung windows rarely use counterweights. Instead, either spring balances or steel coils are used to balance the weight of the sash as it is raised and lowered.

Why Choose Double-Hung Replacement Windows?

Double-hung replacement windows from Keystone Window of Pennsylvania offer a myriad of benefits. Not only do they enhance your home’s curb appeal and interior charm, but they also provide excellent ventilation options. Their unique design allows you to open the top and bottom sashes independently, letting fresh air in while maintaining the utmost security. Additionally, their ease of maintenance and energy efficiency make them a practical and stylish investment for your home.

Our Replacement Windows Are Energy Star Certified

At Keystone Window of Pennsylvania, we understand the importance of energy efficiency in today’s world. That’s why our double-hung replacement windows are Energy Star certified, ensuring that your home remains comfortable while helping you save on energy bills. Our windows are designed to keep the elements at bay and maintain a consistent indoor temperature so that you can enjoy a more sustainable and cost-effective living space.

Standard Argon-Filled Double-Hung Replacement Windows

The introduction of argon gas between the window panes enhances insulation, reducing heat transfer and minimizing cold drafts during winter months while keeping your home cool in the summer. This advanced technology also helps to significantly reduce outdoor noise infiltration, creating a serene and tranquil indoor environment.

Beyond the immediate comfort, our argon-filled windows contribute to lowering your energy bills by optimizing thermal performance and reducing the strain on your heating and cooling systems. Enjoy a cozier home, reduced energy costs, and a quieter living space with the exceptional benefits of our argon-filled double-hung replacement windows.

Our Replacement Windows Include a Low-E Coating

This innovative Low-E (low emissivity) technology has revolutionized the way we experience our living spaces, offering a range of benefits that go beyond traditional windows. Discover why Low-E coating is a game-changer for your home:


  • Optimal Energy Efficiency: Low-E coating is designed to significantly reduce the transfer of heat through your windows. During the hot summer months, it reflects a portion of the sun’s infrared rays, preventing excess heat from entering your home and keeping your interiors cooler. In the colder months, it helps retain indoor heat by reflecting radiant heat back into your home. This means you’ll enjoy a more consistent and comfortable indoor temperature year-round, all while reducing your reliance on heating and cooling systems.


  • UV Ray Protection: Harmful ultraviolet (UV) rays from the sun can damage your furnishings, flooring, and even your skin over time. Replacement double-hung windows with Low-E coating act as a protective barrier, blocking a significant amount of UV rays from entering your home.


  • Glare Reduction: Excessive glare from the sun can be a real nuisance, making it difficult to watch TV, work on your computer, or simply relax. Low-E coating helps mitigate glare by filtering out a portion of the sun’s intense light, allowing you to enjoy a more comfortable and enjoyable living space without compromising on natural light.
