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.

"Excellent service and product! They checked in with me every few weeks while we were waiting for the order. I was impressed with Sam, who measured my windows and headed the installation crew. He was respectful and patient with his team. They cleaned up after themselves. Before the new windows I had huge windows that didn’t open. Now I feel much safer and get better temperatures in those rooms."

"My experience with Anderson Renewal was amazing! From the first meeting with Miranda to choose my windows and doors to the installation provided by Tim and his crew was a pleasure! I just bought a home built in the 1960's that needed new windows and a new double front door with sidelights. As everyone knows Anderson Windows are great, but it was the people I interacted with from Anderson that made it such a great experience. It took three days for the windows and door to be installed and they "worked" every minute they were here. My huge front door took most of the day to install because they had to put in a new header and other improvements to make it fit! They even put up new drywall on the inside. Many people in the neighborhood have stopped by to comment on my beautiful front door! I think the crew left my house cleaner than it was before they started! Constantly cleaning up after themselves. I am thrilled with my windows and feel lucky to have met the team at Anderson."

"Very professional staff . No pressure sales. The job they do is neat and clean, no cleanup left for the owner. Communication is great. Always informed on the status of of your product, AND the tin of cookies you receive afterwards is a pleasant plus."
