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.

"After years of watching the wind move my drapes and hours of difficult cleaning, I decided to get new windows. I went with Renewal by Andersen because of the great reviews and quality. From Brent who did the consult, Gideon who did the measuring, to Jason, Josh, and I apologize I can't remember the third installers name, this is the most professional company I've ever worked with. I own a 1994 double wide mobile home, so everything in this place is hard to work with. I had a bay window, 6 double hung, 2 awning, and a front door replaced.. They said it would take 2 days and they were done on time! I did have second thoughts about doing this mainly because of the cost, but once it was done, I was very happy I did this."
