When it comes to replacement windows, there are a lot of things to consider before you buy new units. That said, one of the things that may be overlooked is the climate of the area in which you live. Here are some design considerations you should think about before grabbing a replacement window for your home if you live in an area with mixed climates.

Window Design Considerations for Mixed Climates


Before grabbing vinyl replacement windows (or any type, really), one of the things to account for is the climate. If you live in a mixed-climate area, you have to boost solar heat gain during the cold months while reducing the same during the hot months. South-facing windows with overhangs keep out most of the hot summer sun and allow for passive solar heat gain. Windows facing the west, on the other hand, will catch the full force of the afternoon sun while east windows will face this problem in the morning.

Window Area

When picking replacement windows, look at window size as well. A large window area isn’t always going to be the godsend you expected it to be. Homes with larger window areas will use more energy than homes with smaller window areas. Energy use increases with homes that use windows with clear glazing while energy may not increase at all in a large window area with high-performance windows. With low emissivity (low-E) coatings, however, you can achieve low energy use even with a large window area.

Shading Conditions

Overhangs can effectively block the summer sun, allowing passive solar gain for the winter months. Windows with no shading but with overhangs, however, perform worse so you need to take steps to correct the problem.

Window Type

Of course, window type is another thing to consider. Some window types may not be made with the same energy-efficient material, so it’s best to consult an expert before buying your window.
