What Double Hung Means and How They Work
It should be noted that a hung window means that the sashes are mounted within the frame and are engineered to open vertically. When it comes to hung windows, you’ll hear the terms single hung and double hung. This blog highlights some of the benefits of double hung windows.
The Benefits of Double Hung Windows
- Air Flow
Double hung windows became the preferred option when it was determined that they could provide better ventilation than single hung windows alone. Before air conditioning, warmer months would be stifling indoors without a steady supply of fresh air. It was theorized that because hot air rises, having two operational sashes could improve air flow. When some of the windows are opened at the top it allows hot air to escape; and when other windows are opened at the bottom, it allows cooler air to enter and circulates the air flow. Many homeowners still use this method to save energy to cool their homes.
Added Safety
Having a window open at the bottom with a child or pet can present a safety concern. Having the option to open a window at the top, out of reach, can reduce the risk of accidents.
- Cleaning
Having both sashes operational means that both can be tilted in for easier cleaning. Single hung windows require that the fixed, top sash is cleaned from the outside.
