The climate where you live plays a big role in the type of windows you should buy. For hot, humid climates consider using energy efficient models.
Living in a warmer climate has its advantages. However, when most people come home on a hot, humid day they want to kick back and relax in a cool environment in their home. The best windows for hot humid climates are ones that are energy efficient. Models that are improperly sealed can cause heat and humidity to seep in, resulting in a rise in temperature inside your home, which will cause your air conditioner to work twice as hard to keep you cool. It can also create moisture issues that can lead to the growth of dangerous substances, such as mold.
When selecting the right windows for hot humid climates, start by looking at the type of frame and glass you will use. Vinyl and wood frames might cost a little more, but they are also very efficient. When choosing glass, consider the Solar Heat Gain coefficient, (SHGC) which represents the fraction of heat that can pass through it. Glass with a coefficient rating lower than 0.22 is recommended.
Installing multi-paned and low emissive glass can also help keep your building at a lower temperature during the warmer months. By having a low emissive coating (Low-e) applied on the inner side of the outermost pane, you’ll be able to reduce heat transfer between panes. Additionally, hanging canopies over the windows on the south and west side of a house can add more protection and provide shade from the direct radiation of the sun.
