What To Consider About Energy-Efficient Windows

Posted on: 4 August 2015

If you're looking for ways to drastically cut your energy bills, consider installing energy-efficient windows. They really help to block the flow of heat to keep it inside or outside where it belongs. Check out these six important facts to consider about energy-efficient windows.

It's Best to Purchase Them in Summer

There are two reasons it's better to purchase energy-efficient windows during the summer. First, if you have windows installed during colder months, moisture may affect the fit, and the caulk may not set properly. In the warmer months, this isn't a problem. Second, in the summer, you'll often find good deals for August installation. Early summer is usually busy for window installers, but August is generally slow, so it's likely you'll find good deals for August installation. Just make sure to start looking for them in June and July. 

Double-Paned Windows Have Insulating Gasses

If you get double-pained energy-efficient windows, the space between the panes isn't just filled with normal air. It's filled with special insulating gasses. These gasses limit the amount of energy that passes right through the glass, but it also help stops cold drafts during the winter. By insulating the glass, it keeps it warmer. Therefore, when warm air comes in contact with the window, it doesn't cool and drop to create a draft.

They Block Certain Energy Wavelengths

Energy-efficient windows also have low-E coatings, which stop radiant heat transfer by blocking the flow of invisible wavelengths, such as UV light. Not only does this keep the hot air inside or outside, but it also helps protect your furniture. Flooring, carpets, sofas, etc. fade when exposed to UV light, but because Low-E coatings block UV light, your furniture doesn't fade as fast. You can purchase cheap low-E films to place over your current windows. They block UV light and stop radiant heat transfer, but they don't have any of the other same advantages as energy-efficient windows.

There Many Framing Options Available

There are many framing options from which you can choose, so you can find the perfect material to match your home. Vinyl frames are low-maintenance and inexpensive. Fiberglass frames are also low-maintenance, but they are more durable. Aluminum frames are another durable option. They usually have thermal breaks to stop heat loss through the metal. Wood frames are the most attractive option, but they require the most  amount of maintenance. Composite frames are crafted from a mixture of materials blended together. Last, combination frames are made from different solid pieces of material, such as wood and vinyl.

U-Value and Is Important to Check

You may have heard of R-value, which is how insulation is measured. The higher the R-value, the better the material insulates. Well, U-values are similar, but they are how window insulation is measured. So, the higher the U-value, the better the window resists heat loss. Optimal U-values depend on your region, so if you live in Florida, your windows need a higher U-value than windows in Oregon.

They Have a High Return on Investment (ROI)

Energy-efficient windows aren't cheap. They cost about $270 to $800 per window. For the best results, you'll want to replace them all at once. Replacing one or two won't generate the same energy-saving benefits. Energy-efficient windows, however, are a great investment because they have a high ROI. If you choose vinyl energy-efficient windows, you can see an ROI of 72.9 percent added to the value of the home. If you choose wood windows instead, it increases to 78 percent.

Energy-efficient windows are a great investment. Not only do they have a high ROI, but they allow you to cut your energy spending each month. For more information about energy-efficient windows, contact a contractor from a site like http://www.newmanroof.com in your area today.
