Double-Hung Windows Defined

Double-hung, also known as double-sash, are rectangular windows similar to single-hung designs. The difference with double-hung windows is they consist of two operable sashes, top and bottom, instead of only one operable bottom sash. The ability for both sashes to open provides superior ventilation and an added level of safety for homeowners with small children.

							We just completed having 8 new windows installed by Lake Washington Windows and Doors. The entire process went very smoothly. The new Anlin windows are very nice quality windows - a big improvement over the builder grade windows being replaced. The warranty offered by the company is excellent as is their detailed attention to how the window is sealed to assure no leakage.The sales staff was patient while we collected information before we committed to the project. Subsequently, the communication was very good with regards to scheduling. They were patient and accommodative with respect to our availability. The installation team of Dmitri and Sergei were great. They were very respectful and neat when entering the house for the inside work. They did a very high quality job and the new windows and framing looks great. They were patient with all my questions and concerns. They were punctual, very hard workers, and it was a pleasure working with them. We are very pleased having chosen this company.

Aly and Josh helped coordinate the installation and we felt up to date throughout the whole process and the installation team Andy, Johan and Fatu did a fantastic job and clearly treated our house with the same care they would have their own. Cannot recommend this company enough.

							Their staff, especially Jim Marowitz, are top notch. Very informative, upfront, and do not try to upsell you. When picking a contractor for a job it is hard to gauge honesty, but with Jim, he went out of his way to make sure you were happy. He told us what options were probably over the top and recommended what would work best, not what cost the most.

							My experience with Lake Washington Windows and Doors was exemplary from our salesman Michael to the installation process. Our installers Ricky, Joel, and Emilio were extremely courteous and competent. The detail on the caulking and cleanup were standard setting. Our interaction with the office team was equally above par with rapid callbacks. I am not surprised by the performance of this company as I did thorough research before making my decision. The windows we selected were a brand that I had not heard of until now, Anlin. I was originally going to buy fiberglass windows but the more I learned about the Anlin vinyl windows the more I was impressed. Be sure to consider this manufacturer. Overall a great experience from start to finish.

							Lake Washington Windows and Doors was outstanding in every way. Michael in sales was well informed without being high pressured. Our installers Ricky, Joel, and Emilio were communicative, competent, with a skill to work clean. The team put up plastic barriers floor to ceiling to minimize dust and debris. This attention to detail really impressed my wife. We were going to buy fiberglass windows but Michael suggested that we consider vinyl windows by Anlin. The more I researched Anlin the more I was impressed by their technology. I highly recommend you consider this manufacturer. Overall from start to finish our experience with this company was outstanding with no anxiety.

							Ricky, Emilio & Moises did a great job of replacing about a 1/2 dozen windows. They left my place like they found it: super tidy. The new windows really reduce the outside sound, keep the house cozy and are really easy to clean. The sales & project management folks (Ronnie & Jeff) were also great to work with: helped to make informed decisions and flexible with scheduling.

Double-Hung Window FAQs

What’s the difference between a double-hung window and a single-hung window?

The key difference is that double-hung windows have two operable sashes that can move up and down, while single-hung windows only have one movable sash (the bottom). Double-hung windows offer more ventilation flexibility and are easier to clean.

How do double-hung windows compare to casement windows?

Casement vs. double-hung windows differ in operation and performance. Casement windows crank open outward for maximum ventilation and a tighter seal. Double-hung windows slide vertically, offering a more traditional look and easier cleaning from inside.

Why do people like double-hung windows?

Double-hung windows are popular for their versatility and classic appearance. They allow airflow from both the top and bottom, making them excellent for ventilation. They also tilt inward for easy cleaning and fit well in virtually any architectural style.

Why are double-hung windows more expensive?

Double-hung windows cost more because they have two operable sashes with independent hardware, balancing systems, and weatherstripping. The additional moving parts and engineering required for smooth operation increase manufacturing costs.

What makes double-hung windows an excellent choice for families with small children?

Parents can open just the top sash for ventilation while keeping the bottom sash closed and locked, keeping children safe. Many models also feature child-proof locks and limiters for added peace of mind.

Are double-hung windows the same as double-pane windows?

No. “Double-hung” refers to the window’s operating style (two movable sashes), while “double-pane” refers to the glass construction (two layers of glass with insulating gas between them). A double-hung window can have single, double, or triple-pane glass.

Why does a double-hung window cost more than a single-hung window?

Double-hung windows have two operable sashes instead of one, which means more hardware, additional weatherstripping, and a more complex balance system. The tilt-in feature on both sashes also adds to the cost.
