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.

"Renewal by Anderson is definitely the way to go for replacement windows. A representative will come out to your house to discuss window replacements, their Fibrex windows, and cost. You do not have to do all the windows at the same time. We chose only to do 10 windows at this time. The price quoted is good for a full year. A few days later another Representative will come out to expertly measure all windows you are choosing to replace. These measurements are sent to the Renewal by Anderson Factory, where your replacement windows are made. Soon after your order has been processed an installation crew shows up with your replacement windows. Renewal by Andersen is excellent in keeping the customer informed from the start of the process to the final installation. We had a crew of 5 that took 2 days for 10 windows. They were definitely top-notch and you could immediately tell they had been installing windows for quite some time. They were definitely prepared for any situation that came up during your window replacement. One window had evidence of past termite infestation. The wood had to be replaced before the installation of our new window. I generally keep an infrared space heater in that room because of all the 5 bay windows. After our new windows were installed, WOW no heat loss. The room no longer felt cooler than the rest of the house. The windows look fantastic. The outside screens are virtually invisible. We love our new windows. You won't be disappointed!!"

"Every employee I have met in this company has been very kind and nice to speak with (even when I'm out of town and have to tell them I'm waay out of their zone for promotions lol!) Customizing the front door was fun, and I'm very happy with the end result of a brand new door frame that is sealed well and closes so quietly and smoothly! The frosted glass window panels top to bottom really let in an awesome amount of natural light. The manufacturing process went well with lots of updates along the way, and the salesperson was able to answer every question I had about financing. Can't wait to start upgrading the windows next! As a first time homebuyer I feel very secure in knowing I can call the company and they will make sure their product stays up to their quality standards. They are going to help this 105 year old house stand strong for another 100!"
