If you’re considering buying new windows, chances are you’ll probably hear the terms “single hung” and “double hung.” Single- and double-hung windows are popular in many Ottawa homes and businesses because they’re simple, elegant and affordable. However, there are differences between the two you should know about.
Single-hung windows A single-hung window, or single-sash window, is a window with two panes of glass, one on top of the other. The lower window moves up and down while the upper window is fixed. Only the bottom window is available for ventilation. Double-hung windows Double-hung windows have two operable sashes. Both the upper and lower windows move up and down. Rising hot air can escape through the upper window, and fresh air from outside can enter your home through the lower window. Single- versus double-hung windows Both types of windows are easy to install and energy-efficient. However, there are differences in the following areas: Cleaning. Double-hung windows are much easier to clean and repair than single-hung windows. Double-hung windows allow you to clean both sides of the window from inside your home. To clean or repair the upper pane of a single-hung window, you must do the work from the outside. If you have a multi-story home, this may require using a ladder or hiring a professional window cleaner. Most modern single- and double-hung windows have a tilt-in function that allows you to move the windows inward for easier cleaning and maintenance. However, single-hung windows only offer this feature on the lower, moveable sash. Ventilation. Double-hung windows offer better ventilation than single-hung windows. You can choose to open the upper sash, the lower sash, or both. You have only one ventilation option with single-hung windows, which is to open the lower sash. Cost. Double-hung windows have more moving parts and are therefore more expensive than single-hung windows. Contractors on large projects such as condominium complexes generally purchase single-hung windows for the upfront cost savings. Individual homeowners should consider paying more for double-hung windows because they provide greater benefits.
