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.

"Their workers who installed the windows were excellent. Our experience with the sales rep was pleasant. He did not pressure us. He made suggestions that saved us money."

"I would give everyone involved in the whole process a 10 out of 10. With the exception of the window installation crew. They get an 11 out of 10. I can't express in words what an excellent job they did. They went above and beyond."

"Although it is a process and doesn't happen overnight the wait is worth the end results. A Representative will come to your home and walk you through the entire process. It does take a few weeks from the time they send someone to your home to personally measure your windows to the time the factory specifically custom cuts your windows and ships them out. However, the end result is overwhelmingly satisfactory. The crew sent to install them were professional, cleaned up after the job was completed and did the job in half the time they thought it would take. Highly recommend!"
