What You Need to Know About Energy-Efficient Windows

Recently, high-performance and energy-efficient windows have become a standard component of most modern homes. However, selecting the most energy-efficient windows is not always a breeze as there are a lot of confusing terminologies and a number of different options you may encounter. To help you, a trusted residential window replacement specialist shares a brief guide to energy-efficient windows.

Energy-Efficient Windows

Insulated Glass Unit
An insulated glass unit (IGU), commonly referred to as an insulated glazing, prevents heat loss through glass windows and doors. This unit consists of two panes of glass separated by a vacuum or gas-filled space to diffuse heat transfer across a part of the home.

Gas Fills
Gas fills are inert gases pumped inside insulated glass units to improve their thermal performance. Argon and krypton are the most commonly used gas fills by window manufacturers. The use of gas fills helps insulate a room and minimize heat transfer through the window glass. 

Low-E Glass
Low-emissivity (low-E) glass is designed to reduce the amount of infrared and ultraviolet (UV) light that comes through the glass without minimizing the amount of daylight that enters your home. Any reliable window company will attest that climates with long, hot summers can significantly benefit from low-E windows not only in terms of indoor comfort, but also in their air conditioning bills.

U-Value
U-value refers to thermal transmittance. It is the measurement that indicates the rate at which heat transfers through a window. It generally ranges from 0.20 to 1.20. The lower the U-value, the better the window insulates and, therefore, maintains the interior temperature of a home.

Reviews

"Quality product, quality workmanship. Everyone I interacted with at Renewal by Andersen of SW Missouri had pride in their work from sales to financing to project oversight to installation. It must be a great company to work for because that shows in the professionalism of the staff. Best of all, they want happy customers and go out of their way to make sure that happens. Yes, I love my windows (but I knew I would--it's a great product). Friendly, helpful, easy financing, and yes--they pass costs on to the customer for this, but it meant that I was able to get the windows I wanted and needed for my creaky, lopsided old house. Couldn't be more pleased."

"The company representative who met with me initially was very direct, told me how the process would go, explained about why Anderson windows are of such good quality and how they stand by their products and their workmanship. My 3 windows arrived when they said they would, & the men who installed them were very professional, polite, & efficient. They showed me how the windows work and left the room as tidy as it was before they did the installation."

"We just had our windows done by Renewal. They kept us informed about the progress of manafucture & installed at the approximate date. Good qualtity & if you didn't know that there were screens on the windows you would think they were missing. Very clear view. Great in this hot weather, the house stays cool."
