Energy Efficient Windows Block Out Drafts
The U.S. Department of Energy reports that inefficient windows cause homes to lose 10–25% of their heating and cooling energy. In cold climates, air infiltration plays a major role when installing new windows.
What is Air Infiltration?
Air infiltration is the process of unwanted air from the outside making its way into the interior of the home. It’s the cold draft that you feel while you’re sitting by a window in the middle of winter. You can test if your windows are drafty by lighting an incense stick and holding it close to the window. If the smoke moves horizontally, it’s likely that you’re experiencing drafts.
Drafts enter through various points of the window, including:
- The sash
- The sill
- Where the sash meets the sill
- The perimeter
- Where the sash meets the rail
The most energy-efficient windows in MA are measured in cubic feet per minute (CFM), with the average industry rating between .12 and .3 CFM. Windows that contain the lower rating are losing roughly 24 cans of air per minute. The best windows for cold climates lose only 0.8 cans of soda per minute.
Keep in mind that there is no such thing as a window that is 100% airtight. Air can even move through the cavities of an insulated wall! However, for the window to be energy efficient, it must have as little air infiltration as possible.
Air infiltration is undoubtedly important, but there is another major component to consider with cold weather windows: the glass package.
Cold Weather Components of a Glass Package
Just like air infiltration performance, not all glass packages are created equal with replacement windows in Massachusetts. You’ll find that some windows don’t come with any of the important technologies at all, resulting in a home that always feels cold during the winter and fall.
Extreme cold weather windows are designed to keep your home cozy while battling the elements. What are the most important window technologies for cold weather climates?
U-Factor
A window’s U-Factor determines how good energy-efficient windows are at preventing heat loss during the winter. The ratings range from 0.14 to 1.20. Replacement windows with a low U-Factor provide the best insulated windows for cold weather and higher resistance to heat flow. When your U-Factor is on the higher end, heat is easily lost through your windows in the wintertime.
Solar Heat Gain Coefficient
This metric ranges from 0-1. It measures how well your windows block heat that’s created by sunlight. Whether it’s summer or winter, the sun can warm your home through the windows and, in some cases, cause overheating in hot weather. However, the right rating (and comfort level) depends on the climate. For us homeowners here in MA and other areas of New England, we want a higher SHGC rating. This allows the sun to help naturally heat the home in the winter. Without the proper SHGC rating, your home will feel cold throughout the entire season.
Low-e
Low emissivity glass contains an invisible layer that’s thinner than a human hair. In cold climates, extreme cold weather windows with low-e coatings applied to the interior glass prevent heat loss. In fact, they can help reduce heat loss by as much as 30 to 50%!
Argon and Krypton
Argon and krypton are natural gases that are also invisible. These gases are denser than air and belong to a special group of gases known as inert or noble gases. Their purpose is to provide thermal efficiency to the window, and the heaviness of the two gases increases insulation and further prevents heat from escaping.
Triple Pane Windows
One of the best replacement windows for cold climates includes those with triple pane glass. Triple pane windows offer an additional layer of glass than the standard dual pane windows. This extra layer of glass adds another level of efficiency, especially when it’s filled with krypton gas that’s perfect for triple pane’s tight chambers. When you upgrade from single pane windows to triple pane, you can potentially save over $500 a year on your energy bills!
