What Makes Windows Energy Efficient?

Whether you’re in the market for new windows or you’re simply interested in testing the windows you already have, it’s important to have a bit of know-how when it comes to energy efficiency. What exactly makes a window more energy efficient? When you’re paying $300 to $700 per window installed, it’s good information to have. Keep reading to learn exactly what makes your windows energy efficient.


While glass alone won’t make a window energy efficient, the way glass is used in your windows can help a lot. For example, a single glass pane in a wooden window frame won’t do much at all to retain heat. Double- and triple-paned windows, on the other hand, have a much higher heat retention rate. But remember: the number of glass panes doesn’t necessarily determine energy efficiency. For the best results in your area, it’s best to consult the company that installed your windows.


Nearly all energy efficient windows have this feature in common. Warm spacers are designed specifically to reduce conductivity. They are what separate the glass panes within your windows, and are the most vulnerable places for heat loss during the colder months. Warm edge spacers are used primarily to prevent the loss of heat or cool air from your home. If you feel air leakage coming from a window that’s supposed to be energy-efficient, it’s likely there’s a glass or spacer issue within.


Certain types of energy efficient windows have what is called a glaze over the glass. This glaze, which is typically clear and can’t be seen with a naked eye, can actually help your windows be more energy efficient. If you want, you can also opt for tinted glazes. Ultimately, glazes help prevent sunlight from heating up your home and can prevent the transference of cold air, as well.

Determining whether windows are energy efficient or not is really a matter of knowledge. And now that you know these handy facts about your residential windows, you’ll be able to make informed decisions about them.

How Can Commercial Window Replacement Save Money for Your Business?

When almost 44% of renovation jobs are for doors and windows, it becomes necessary to ask yourself if it’s time to give your commercial windows an upgrade. Whether you’re fed up with high energy bills or it’s an aesthetic issue, the time has to come eventually.

Of course, one of the biggest detracting factors for commercial window replacement is cost. But in the long run, commercial window replacement can actually save you money. How? Keep reading to find out.

Lower Energy Expenses

This is the biggest benefit of replacing commercial windows. In most cases, a business will already have higher energy costs than the average home. You’re operating in a larger space and it needs to get heated. The lights need to turn on. But when you choose windows with insulated frames and energy-efficient glass, you’re making a solid investment in your financial future. Those windows will likely end up saving you hundreds, if not thousands, of dollars in energy expenses.

When you choose new, energy-efficient windows, you’re guaranteeing that there will be minimal loss of hot or cool air from your building. Less air loss means less time spent heating or cooling the building, which in turn will result in lower energy bills.

Less Window Maintenance

When you call in commercial window installers to replace your old windows, you can rest easy knowing there will be less maintenance involved. Older windows may require more frequent repairs and upkeep, especially if you’re forced to take DIY measures to prevent hot or cold air from escaping. Investing in new windows means investing in all new hardware. So whatever makeshift draft-proofing you were doing before can be thrown in the trash! With your new energy-efficient windows, the only maintenance you’ll need to do is give them a good cleaning every so often. Talk about a time saver.

The decision to replace your commercial windows can be an easy one to put off, especially if you’re stringent in your spending. But when you think of all the time, money, and effort you’ll save with new windows, it becomes apparent that it’s well worth the investment.
