Windows can be a major source of heat loss in winter and heat gain in summer. The principle energy concerns for windows include U-Value and Solar Heat Gain (SHGC).

U-Value measures how well a window prevents heat from escaping the home. Solar heat gain measures how well a window blocks heat from the sun.

These values are expressed as a number between 0 and 1. The lower the value, the better the window is at preventing heat loss or blocking the sun’s heat. Look for these factors when comparing different windows and options.

You can find our window performance measurements for each of our product lines.

In warm weather, Low-E glass reflects the sun's heat and reduces solar heat gain.




LowE Winter 1


In cold weather, Low-E glass reflects the heat back into the home, reducing heat loss.



Window Materials Influence Efficiency
With today’s advanced window systems, there are many features to consider when deciding on the right window for your home. Window frames come in several different materials and vary in performance.

With the glass making up the greatest proportion of the window, you should review all of the glass options available—from Low-E coatings and tinted glass to double glazing with warm edge spacers.
An energy-efficient window is one that helps to minimize the use of artificial heating and cooling in a building.

Lower energy bills.
Our standard double glazing and CôsE insulating glass helps cut your heating and cooling costs by up to 30%.
