Heat loss through drafty windows can be responsible for up to 30% of your heating costs. Energy-efficient windows can cut your energy bills significantly, but to maximize the potential energy savings, you have to pick the right one for your home. Comfort King Windows & Doors, your go-to choice for quality windows and patio doors, shares some tips for buying energy-efficient windows below.
Look for the ENERGY STAR® Label – The first thing you should look for is the ENERGY STAR label. Only products that have met stringent requirements for energy performance can receive this certification. However, you shouldn’t buy a window just because it’s been certified by ENERGY STAR. Look at window labels to check for ratings like U-factor and solar heat gain coefficient (SHGC) as well.
The U-factor indicates a window’s insulative capabilities. The lower it is, the better a window can prevent heat transfer. SHGC, on the other hand, gives you an idea of how much solar heat can pass through a window. The lower the SHGC rating, the less heat a window allows through into your home.
Find Out Which Climate Zone You’re In – Ideal U-factor and SHGC ratings depend on your climate zone, which you can look up online. As a rule of thumb, windows with low U-factor ratings are better suited to cold climates, while windows with low SHGCs perform better in warmer climates.
Pick the Right Frame – Frames can also affect a window’s energy efficiency. Since each material has its pros and cons, you’ll have to do your research. Remember, a one-size-fits-all approach won’t work in a windows replacement project. The right frame (and window) for you is one that’s suited to your local area’s general climate.
Quick Tip: Hire a Qualified Contractor
One more thing: make sure only a qualified contractor installs your new windows. This is because for an energy-efficient window to perform its best, it needs to be properly installed as well.
