What You Should Know About Energy Efficient Windows

When it comes to protecting your home and increasing its market value, there’s no better investment than in energy efficient windows. With high-quality materials, built-in protection, and the ability to decrease heating and cooling costs, energy efficient windows should stand as any smart homeowner’s secret weapon against weather, time, and the changing energy market. If you’re looking to replace the windows in your home, or simply want to learn more about energy efficient windows, read on to find out the facts.

What They Are

When a window can provide the proper insulation against weather and other deleterious outside factors, that window is considered energy efficient. That said, there are many different types of energy efficient windows, as well as specific targets and focal points for each model. The most common way to tell whether or not a window is at peak efficiency is to check its U-factor. A U-factor is a way of measuring how much heat or cold escapes through each window, creating a helpful rubric for gauging a certain window’s efficiency. If a window’s U-factor is low, its energy efficiency is high. It the U-factor is high, you’ll want to keep on looking. U-factors aren’t the only determinate, however–certain materials are known to be more efficient than others. For instance, fiberglass is considered highly efficient, while aluminum falls low on the efficiency scale.

How They Work

Energy efficient windows are built to do one thing: Protect your home from leaks, sun damage, and any other unwanted elements. How they achieve this varies from model to model. However, what most energy efficient windows have in common, next to good material and a low U-factor, is great insulation. Whether a window achieves this through double paneling, inside insulation running through the track of the window, or by re-directing solar energy, a window’s ability to trap in heat and keep out cold (or vice versa in the summer) is its most important factor.

While many windows offer superior material and great insulation, some windows will even provide their own form of heat to home, rendering the need for traditional heating completely unnecessary. These windows save solar energy and retain it as thermal heat. This heat, in liquid form, then provides heat throughout the entire home without any intervention from a central heating system.

What They Can Do

In addition to keeping your home warm and allowing homeowners a good amount of control over their home’s temperature, energy efficient windows protect furniture inside the home from damage caused by prolonged periods of sun exposure. Regular windows allow the sun to penetrate through and fade furniture and wood floors, while energy efficient windows are created to combat the sun’s glare while storing up the solar power and redirecting it. If your windows are tinted, you’re even better protected against the sun’s harmful effects. Low U-factor windows will be able to protect your home from sun damage while reducing the amount of heat transmitted into the room. This allows homeowners to use air conditioning less, creating smaller energy bills and a much smaller carbon footprint. For this reason, many larger offices and factories have already started to make the switch to energy efficient windows.

How Much You’ll Save

When it comes to switching out older window models for energy efficient windows, the savings are immense. Poor insulation in homes causes many homeowners to pay double the amount in heating and cooling bills that they might have otherwise paid in a well-insulated home. Low U-factor windows–especially those made out of a good material that doesn’t transfer heat, can save homeowners up to 25 percent annually on their heating bills. Similarly, with warmer surfaces, built-in weather-stripping, and the ability to deflect sunlight, air conditioning bills in homes with energy efficient windows were reduced by almost the same percentage.

Other Benefits

With regards to other weather-related effects like frosting, condensation, and warping from moisture, energy efficient windows have built-in protection from all kinds of water- and heat-based damage. With triple-glazing, insulated framing, and performance tinting now coming with the cost of most standard energy efficient windows, the level of protection your home will receive will be unparalleled. The newer models of energy efficient windows are also built to last, increasing the value of your home with each passing year. If you’re looking to invest in your home’s protection, quality, and market value, energy efficient windows are the only way to go.
