How to Tell if Your Windows Can Handle the Cold

Not all windows can handle frigid weather, which is why you should do your research before purchasing one. There are a few things you need to look for in a window. Abby Windows, one of the state’s top window replacement companies, lists them below.

The ENERGY STAR® Label

The first thing you should look for is the ENERGY STAR label. Only windows that have met the Environmental Protection Agency’s stringent standards for energy-efficiency have this label, so it’s a quick way for you to weed out replacement options that won’t be able to provide what you’re looking for.

NFRC Ratings

Next, check the National Fenestration Rating Council’s (NFRC) ratings, which are found on the label. These ratings will indicate whether a window’s more suited to warm, cold or temperate climates. Listed below is an overview of what the ratings mean:

U-factor - This rating gives you an idea of the window’s insulative capabilities. The lower the U-factor, the better it can insulate your home and prevent heat loss.
Solar Heat Gain Coefficient (SHGC) - The SHGC indicates how much heat from the sun a window can block. Window installation contractors recommend those living in cold climates to install windows with a high SHGC rating. That way, you’ll be able to maximize natural heating.
Air Leakage - Given that drafty windows are responsible for up to 30% of the average home’s heat loss in winter, you should install an airtight window with a low air-leakage rating.

Gas-Filled Windows

Here’s another thing you should know: most energy-efficient windows are filled with argon or krypton gas. Manufacturers fill the space between the window’s glass panes with these colorless, non-toxic gases to improve a replacement unit’s insulative abilities.

Make sure only a qualified contractor installs your new energy-efficient windows!
