Windows Can Account For Up To 30% of Energy Consumed Annually

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 AMSCO’s window Performance measurements on our Web site for each of our product lines.
Low-E Summer In warm weather, Low-E glass reflects the sun's heat and reduces solar heat gain.
Low-E Winter
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 different materials and vary in performance. And, because the glass makes up the greatest proportion of area in a window, you should review all of the glass options available—from Low-E coatings and tinted glass to insulated glass units with warm edge spacers.

Energy Saving Tips

Even if you are not ready to replace your windows just yet, you can still make a difference and conserve energy in many other ways. Here are just a few ideas:
  • Caulk and weatherstrip around windows and doors to seal out any drafts
  • Close window coverings in the summer to help block out the sun’s heat and open them in the winter to allow the sun in. Be aware of any excessive heat build-up behind the window coverings so as not to cause damage
  • Caulk around any pipes, plumbing or duct work that go through exterior walls
  • Repair leaky faucets and toilets promptly
  • Replace high use incandescent lightbulbs with compact fluorescent lightbulbs
  • Use only full loads in dishwashers and your clothes washer
  • Insulate your water heater. Always follow directions carefully when installing an insulation jacket
