Single Hung Window

What is a Single Hung Window?

A single hung window means the lower sash can open and close, but the top stash remains stationary. Let’s look at the characteristics of a single hung window:

  • Ventilation: Less ventilation than a double-hung window, due to only the lower sash opening.

  • Air Infiltration: May have reduced air infiltration since the upper sash is sealed

  • Cost-Quality: Lower cost then double-hung, but are typically lower quality and mass produced

  • Ideal Use: Not typically used for residential homes, rather best suited for large commercial buildings such as apartment and townhome complexes

  • Maintenance: Single hung windows can only be properly maintained from the exterior, making them a poor choice when considering long-term maintenance

Double Hung Window

What is a Double Hung Window?

A double hung window means both the upper and lower sash of the window can open. Here are some features of a double hung window:

  • Ventilation: More ventilation options, as both the upper and lower sashes open

  • Energy Efficiency: Double hung windows can be slightly less energy efficient, but other factors more likely to influence energy efficiency

  • Cost vs. Benefits: While slightly higher cost than a single hung window, the benefits are likely to far outweigh any cost savings

  • Maintenance: Double hung windows typically tilt inwards for cleaning and maintenance, making them a great choice for those looking for an easy window to clean and maintain

  • Recommended Use: Nearly all residential window replacement should use a double hung over a single hung window
