saving energy • Low E-Glass

No other single component of a house affects comfort and energy consumption as much as windows. Per square foot, your windows lose more heat in winter and gain more heat in summer than either your walls or roof.

Saving Energy - Part 1


Energy Saving Low-E Glass
Keeps the Hot Air out in the Summer and The Warm Air in During the Winter!
In warmer conditions, energy-saving LOW-E windows reflects away both solar radiation (direct from the sun) and also the long-wave radiation & heat energy (as from a sidewalk or driveway), yet still allows visible light to pass through.
In cooler conditions, LOW-E energy-saving window glass reflects RADIANT ROOM HEAT back into the room, while allowing a high level of visible light to pass through the window to add additional warmth to the room.

Ice, snow, wind, rain, heat & humidity. Montreal gets some of the toughest, most extreme weather conditions imagineable! All the more reason to think carefully about the choice of windows for your home.

Especially since they can account for up to 30 percent of the year-round energy consumed in a typical house.

To help make your home energy-efficient, Martin Industries uses the latest and best options in technology for saving energy. These include LOW-E, Argon gas, the most advanced weather stripping techniques and more.

For example, switching from single-pane windows or damaged sashes to double-glazed, low-e windows with insulating sashes will improve comfort substantially. In addition, energy-efficient windows save heat when it is cold, protect furnishings from fading, reduce infiltration of outside air, keep out unwanted noise, allow in fresh air, and prevent glare. Imagine, all that in one window!

Window Basics
During the heating season, there is a large temperature difference between the inside air and the outside air. Cool air descends and hot air rises. If a window is cold while the interior air is warm, there is a tendency for the window glass to cool the air adjacent to it. As warm air hits a window surface that is cool, the warm air is cooled and drops toward the floor, causing drafts.

During the cooling season, although the outside air temperature feels hot at 90°F and above, the differences between outside air temperature, inside air temperature, and body temperature are much smaller. This slows air movement, so drafts are much less noticable.

What many people perceive as a draft, is a combination of the cool air falling downward and the heat loss by thermal radiation from their warm skin to the cold glass surface. (Remember that for single-pane windows, the inside surface of the glass is closer to the outdoor temperature than to the indoor temperature.)

Condensation can also be a problem on single-pane windows when the outside air temperature is low and indoor temperature and humidity are high. WHAT TO DO ABOUT SAVING ENERGY? more about energy efficient windows - Part 2
