The US varies in climates and temperatures throughout so you have to pick a window that will stand up to certain weather patterns or heat waves. In the Northwest, windows are exposed to a lot of moisture so the materials need to be able to withstand the precipitation. Vinyl, composite, and wood-resin are the most common for this geographical location. Wood windows are generally not a good choice for the area, the moisture causes the wood to warp or penetrate the wood and cause it to deteriorate faster. The Southwest is a sunny spot in the US, and windows are an important choice depending on the sun exposure. Based on the climate, most types of windows can be used. Sunlight is the biggest factor in that area, so it is important to have solar heat resistance on the panes of glass. Having cheap glass can cause negative effects on heating and cooling bills, for the sun is able to come through and heat up the home. In the Midwest, a different factor to take into consideration would be wind and twisters. For that general reason, homeowners tend to favor insulated double hung windows and casement windows, for they generally hold up well to strong winds. The highest demand of windows in the northeast are double hung windows. Wood frames are a very common choice in the area for the timeless and traditional look. In the southeast, the biggest choice homeowners consider is the heat. Windows can be a great energy saver in locations that are greatly exposed to sunlight. Double pane windows with low-e glass are the most common choice. It reduces the amount of sun exposure so heating and cooling costs are lower. Depending on the area of the Southeast, homeowners need to worry about storms and hurricanes. Homeowners tend to choose aluminum windows based on the strength and durability to withstand tropic like storms. Whatever climate you live in, it is important to choose the correct style and material to highlight your home and endure the weather.
