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.

"I just bought my first house. My patio sliding door was rotten. So, I needed it to replace it. Renewal by Anderson of Southern Missouri listened to what I wanted and delivered it. They did a fantastic job of installing and cleaning up afterwards. They did it even in freezing rain that day I was scheduled to have it replaced. They even had a follow-up to check things out and do the touch ups. I'm amazed at there work. Great job Renewal by Anderson."

"On Feb 1,2024 my husband and I selected Renewel by Andersen for windows for our entire house. It made our house more beautiful with the picture windows. Made the outside more attractive, and on the inside. We did 14 windows. We had 4 men come to do the job in 1 day And they were very friendly, efficient,fast and cleaned up inside and outside perfectly. And most importantly we noticed the heating furnace runs less,therefore saving us money on our gas bill. We live in SW Missouri. We recommend anyone who wants to replace windows in their home to pick Renewal by Andersen. Sincerely, Darius and Nancy Durman"
