Install Energy Efficient Windows, Save Money!
By zarafshan qayyum
The drastic environmental changes have urged people to think about using energy-efficiently. From individual residential homes to upscale malls and commercial offices, every structure is made keeping the values of energy efficiency in context. Even manufacturing industries are working on their energy sources and consumption strategies. However, achieving absolute energy efficiency is not a piece of cake. Thermal performance is influenced by everything. But windows and doors are the main outlets of energy loss. You can effectively maximize the thermal performance of a home by working on glass windows and doors. Considering the importance of energy efficient windows, we will discuss them in detail in this blog.

What Are Energy Efficient Windows?
Energy efficient or energy-saving windows are designed to reduce the usage of artificial heating and cooling systems in a building structure. These windows are insulated to keep the heated or cooled air from escaping your home interior. The air insulation improves the HVAC system and lowers the energy consumption of the home. Thus lowering your energy bills. Energy efficient glass windows ensure energy conservation. Therefore it’s a smart move to invest in insulated glass windows.
How Much Can You Expect to Save With Energy Efficient Glass?
According to the statistics, over 40% of the annual heating and cooling costs can be directly related to energy loss through windows. By installing the insulated windows, you can effectively lower the energy consumption.
- By replacing the regular single pane windows with energy efficient ones, you can reduce the carbon dioxide emissions by 1000 to 6000 pounds and save up to $100 to $600 per year.
- While the average annual savings are around $30 to $200 for replacing the double-pane windows with energy efficient glass windows. You can cut the emissions by 250 to 2000 annually by installing insulated glass windows.
This is just a rough idea for a standard residential space. The energy savings can mount up to thousands of dollars for larger commercial spaces.
Glass Used for Enhanced Energy Efficiency in Windows
Insulated glass windows typically have multiple panes of glass in their basic structure. The multi-pane design makes it possible for the glass to prevent the outside temperature from affecting the interior ambiance. Below are the three most commonly used glass types in energy efficient glass windows.
1. Laminated Glass
The laminated glass typically has two or three panes of glass that are fused together with the help of an adhesive resin. This interlayer of adhesive resin is responsible for the exceptionally high strength value. Laminated glass is potentially unbreakable and it blocks the hot or cold air from entering the house. So laminated glass qualifies as a great glass type for energy efficient windows. Laminated glass windows are typically used in commercial applications.
2. Insulated Glass
Insulated glass is specially designed to keep thermal insulation in view. Such glass also features a multi-pane design. The only difference is in the interlayer material. Unlike laminated glass, the layer between the glass panes is either filled with inert gas, or a vacuum is created between the glass panes to restrict the airflow. Special spacers are used around the perimeter of the glass panes to ensure complete thermal insulation. Insulated windows are mostly used for residential purposes.
3. Low Emissivity Glass
Low emissivity or Low-E glass is another type of glass used in insulated windows. This type of glass has a coating of metallic oxide layer on the surface. The invisible coating allows the natural light to pass through and illuminate the interior space while deflecting the UV and infrared rays back into the environment. UV and infrared rays are mostly responsible for heating up the space. So by blocking them, the insulated glass windows effectively help in reducing the energy consumption. Low-E coating is a brilliant way of saving energy. The coating is selectively reflective and only allows some specific wavelengths and frequencies of light to flow through the glass. So it is perfect for saving energy.
Can you Replace Traditional Glass Windows with Energy Efficient Windows?
a temporary method. Moreover, this technique is not very energy effective. The best approach to achieve maximum energy efficiency is to replace the traditional windows with insulated glass windows. So the recommended method is to get insulated window replacement by the professionals.
How Much Does Energy Efficient Glass Cost?
Unlike standard windows, insulated windows have a more comprehensive structure. So they typically cost more than the traditional glass windows. You can expect to pay around $300 to $1000 for each insulated glass window. It might seem like a big investment up front but you would get the best restaurant on investment with time. This investment will effectively lower the energy costs by 7 to 15 percent. So it’s highly recommended to get an energy efficient window, irrespective of the cost.
Final Words
Energy efficient glass windows have proved their worth in the area of energy conservation. So if you already don’t have insulated windows, it is the right call to opt for window replacement. It’s a one-time investment that would definitely benefit you for a long time to come.
