Storm Window
Definition and meaning of Storm Window in real estate.
Storm window is an additional window pane installed on either the exterior or interior of an existing window to improve insulation and protect the primary glass from severe weather.
In more detail
These windows are common on older homes with historic single-pane wood windows, offering a cost-effective alternative to complete window replacement. They create an insulating pocket of air that reduces drafts, decreases heat loss, and dampens outside noise. Storm windows are typically made of glass, acrylic, or rigid plastic, and they can be permanent or seasonal.
Although modern double-pane and triple-pane windows have reduced their popularity, storm windows remain a budget-friendly option for improving energy efficiency.

Frequently asked questions
Do storm windows help with noise reduction?
