The differences between a bay window versus a bow window involve the number of individual windows and the angle at which both windows extend from the home. A bow window has four to six individual windows that form a curve outside the exterior wall. A bay window usually has two small windows on the edges that angle outward from the exterior wall and a large window in the middle that’s parallel to the home’s exterior wall.

Egress windows are typically required for basements with habitable space or living quarters. Not all basements or lower levels require egress windows. However, egress windows are required in homes with living spaces such as bedrooms and living rooms in a basement. The International Residential Code and International Building Code require sleeping rooms to have a specific size egress window. Check your local building codes to confirm the requirements in your area.

In short, it depends. After 20 years, the glass in your windows is less energy efficient, which can cause increased electricity bills. You might also see signs of water damage or natural wear and tear over the years. However, with proper maintenance, some window frames can last up to 50 years, so you may only need to replace the glass to save on energy. 

At the same time, window replacement is a major investment, so replacing the glass in rooms most impacted by outdoor temperatures is one way to avoid going all-in to replace your windows.

Storm windows have about the same life span as standard windows—between 20 and 30 years. Vinyl and wood storm windows last longer than aluminum, but they all fall within that life span range. Of course, how long your storm windows last will depend on how much severe weather they see. Direct impacts, in particular, can quickly reduce how long your storm windows last.
