A lot of the time, window shoppers mostly consider two factors when faced with choosing a new window: its aesthetic beauty and whether or not they’ll be sturdy enough not to allow leaks. However, with the advent of so much information available, today, homeowner’s look beyond aesthetics when it comes to choosing their windows. That is not to say that looks should be disregarded, however, what’s more important today is whether or not a window conserves energy. A new generation of environmentally conscious consumers have driven the demand for a whole new market for energy-efficient windows.
Now is a great time to choose green, as the manufacturers of energy-efficient windows are many and the quality of their products keeps getting better. But before you decide which direction to take, make sure you know all there is to know about this type of window, factors you should take into consideration, and of course the best brands to choose from.
Types Of Energy-Efficient Windows
Energy-efficient windows will prevent the hot or cold air in your room from escaping. These kinds of windows will lower your utility bills and your carbon footprint. You can expect to save between 21 and 31 percent on cooling and heating bills within a year. They will also make your life more comfortable with their unique traits, whether it be blocking out noise or harmful lights.
You can find a few types of these value windows on the market. They are all essentially the same product, but some with more improvements. All of them are energy-efficient and prove that window evolution is real.

Double-Pane Windows
Double-pane, or double-glazed, windows are built with two layers of glass separated by air or an insulating gas (usually argon). Unlike older single-pane windows, the two-layered glass can protect your home from bad weather and noise outside. Most new homes today have double-glazed windows installed during construction, making this type of window a requirement and not just an option.
Triple-Pane Windows
Like double-pane windows, triple-glazed windows come with extra layers to protect. The three layers of glass and two of insulating gas ensure maximum protection and make your windows even more energy-efficient.

Low-E Windows
Low-emissivity or Low-E windows have a thin metallic coating between the glass. This coating is thinner than human hair and helps keep the home temperature consistent by reflecting the outside temperatures inside. This type of window can also minimize the amount of ultraviolet and infrared light that enters through your glass, without affecting the amount of natural light in any way.

Factors To Consider While Choosing Energy-Efficient Windows
Before you embark on the journey of replacing your windows, there are five factors that you should take into consideration. Whether it be related to aesthetics, functionality, or efficiency, these five factors should be looked into in detail, to ensure that your house will be well protected and gorgeous at the same time.

The Window Frame
There’s no one right answer when it comes to choosing the perfect frame for your windows. Every frame material comes with its own pros and cons, but most are dependable under most circumstances.
Vinyl
Just because vinyl is one of the more affordable options for window frames it is not any less efficient. A well-constructed and properly installed vinyl frame is as good as any other reputable choice. The only downside of vinyl is that it is the most limited when it comes to color choices.
Aluminum
Aluminum is one of the strongest frame materials out there. Aluminum frames are a great choice if you live in a rainy and humid climate or in a hurricane-prone region. With that said, aluminum is not the best choice for heat loss and transfer.
Wood
Wood window frames offer the best insulative value and are arguably the most aesthetically pleasing. Built well, wooden frames can easily stand the test of time. Unfortunately, ones that are not built well might rot with time, especially if you live in a humid climate.
Fiberglass
A well-built fiberglass window frame can stay in great condition even after 50 years. Fiberglass is stronger than vinyl and can withstand harsh weather. Its most common downside is that it is harder to customize into your preferred designs.
Wood-Clad
Wood-clad window frames offer the best of both worlds. They usually have a low-maintenance exterior, like vinyl, and a wooden interior that fights temperature transfer. Unfortunately, like wood frames, they are not advised in extremely humid areas.
Type of Window Glass
While the frame is important, what’s inside the frame is perhaps more significant to consider. It’s no argument that your house needs the most energy-efficient windows, and they need to be of the highest quality too. Most contractors will tell you that one of the best options is a double-paned, Low-E, and argon filled window. For harsher climates, a triple-pane glass window would be more advisable, but it might cost you a little extra.

Window Design
The design of your windows is completely dependent on the exterior and interior of your house, your taste, and most importantly on the window’s efficiency. Certain windows are both beautiful and efficient, and should be considered with every new house renovation. Window styles that stand out are double-hung, casement, and picture windows. They all have high functionality, efficiency, and add charm to any design style.
Where You Live
Another influential factor to making your window choice is where you live. Your house’s geographic location and the weather conditions in the area determine which direction you will end up taking. Some materials and types of glass are better suited for hot and humid weather, while others are recommended for colder weather. There’s also the consideration of whether your house is in a region prone to natural disasters, and which kind. Thanks to energy-efficient window glass, most of these problems are easily solvable, as these types of windows can lock in the hot and cool air.
Proper Window Installation
Even the most high-quality materials won’t last long if not installed properly. That is to say, if you do everything right but mess up with who you trust your installations with, you might end up being disappointed. This is where licensed contractors come in handy. Make sure you’ve done the best for your house, because a correctly installed window can last you a lifetime.
