Where you live can affect the performance and lifespan of your windows. The National Fenestration Rating Council (NFRC) has created performance criteria for windows, which is different for every climate zone. This guide will help you determine which features you need to look for when purchasing new windows.
In this post, your local replacement contractor, Renewal by Andersen® of San Francisco, discusses the best windows based on your home’s location.
1. Pacific Northwest
Summer doesn’t last that long in this area. Look for windows with higher solar heat gain coefficient (SHGC) and high-temperature transference resistance. Choose windows with a U-value of 0.3 or lower for the best insulation. Avoid wood materials like pine as they are more prone to rotting especially in humid areas. Any damage on the cladding can cause water to seep into the wood.
Windows with good insulation properties work best for this region as it experiences hot summers. Protect your home from harsh sunlight with high solar heat resistance windows. Products with an SHGC lower than 0.3 are ideal. Spectrally selective coatings allow natural light to pass through the glass without transferring heat indoors.
This area experiences extreme weather, hot and humid summers, and freezing winters. Southern and central Midwest homes would benefit from windows with SHGC and U-value ratings of 0.3 or lower. However, a higher SGHC is recommended for northernmost regions. According to experts, casement windows work well for windy areas.
Choose windows with low thermal conduction if you live in this region. Consider windows with U-value and SHGC ratings of 0.3 or lower that have low-E coatings and at least two glass panes separated by gas fills.
Make your home more energy-efficient with windows that can block solar energy. A double-pane window can protect your home from hot and cold weather. Invest in windows with spectrally selective low-E glass.
6. Coastal Southeast
This region is prone to hurricanes, which can damage windows and doors. That’s why it’s important to choose impact-resistant windows. Building codes in this area require windows that can withstand impact, structural pressure and air, and water leakage.
