Comfort Benefits

The comfort of your home during both winter and summer months can be largely dependent on your windows. Older single pane windows, dual pane windows, and even gas filled double pane windows often do not provide enough insulation to maintain a comfortable inside window temperature. The colder or hotter the interior glass temperature is, the more energy will be required to maintain a comfortable home temperature.

Winter Comfort: If your windows do not provide sufficient full-frame insulation performance, air may not only be leaking out of your windows, but also, as the interior glass temperature of a window becomes colder, it cools the air next to it. The cooled air then drops to the floor because cold air is heavier than warm air and more warm air moves in, close to the cold window that is then cooled. This process creates a cold air circulation that causes a draft and leads to a large amount of heat loss.

SeriousWindows can provide nearly unbeatable interior window temperatures, even in zero degree weather. On average, our windows maintain an interior temperature of 65 to 70 degrees even in the coldest of winters. Because the interior temperature of our windows is so high, it virtually eliminates that drafty cold air feeling that you would get from most other windows. The warm interior temperature of our windows also reduces the amount of cold air circulation caused by cold glass and therefore can drop your heating use dramatically.

Warmer Interior Glass Temperatures Offer Greater Comfort

The green bar in the above graph represents an interior glass temperature that is considered the most comfortable. SeriousWindows offer high interor glass temperatures for improved comfort and efficiency.

Probability of Discomfort Due to Draft vs Cold Interior Glass Temperature

Discomfort is most often caused by cold interior glass temperature rather than a draft. SeriousWindows warm interior glass temperatures even in zero degree weather create a more comfortable environment.

Summer Comfort: In the summer, direct sunlight creates a warm interior glass temperature that causes overheating and discomfort. The same draft problem that occurs in the winter also occurs in the summer, but in a reverse effect. The warm interior glass temperature warms the air next to the window and causes it to rise. The cooled air from your air conditioner moves in next to the window and the cycle begins again. The air that is heated by the warm interior glass temperature counteracts the cooling effects of your homes air conditioner, creating hot spots in your home and driving up your cooling costs.

SeriousWindows’ spectrally selective glazing reduces the solar radiation coming in through the glass that is associated discomfort without impeding light and views. SeriousWindows also maintain a consistent interior glass temperature that prevents hot air drafts and hot spots in your home for a more comfortable interior environment.

Probability of Discomfort Due to Sunlight and Hot Interior Glass Temperatures

Discomfort is most often caused by excess sunlight rather than hot glass. SeriousWindows utilizes low-E coatings to reflect excess sunlight back outdoors to maintain a more comfortable environment.

All data from the Efficient Windows Collaborative. The data used for SeriousWindows was based on an average glass package that featured a Low-E coating, gas fill, suspended film and a low or high SHG dependending on climate.
