Qualities of an Energy-Efficient Window

Energy-saving home improvement projects are a smart move. They save you energy and money in the long run and contribute to a greener Earth. If you’re planning to start with energy-efficient windows, it’s best to do your research first. What makes a window energy-efficient? In this article, trusted window replacement contractor California Energy Consultant Service explains the different qualities of an energy-efficient window. 

Low-E Glass

Energy-efficient windows are usually composed of Low-E or low emissivity glasses. Low-E glass is made of a transparent coating that blocks the heat passing through the glass. Even with the natural light coming through the windows, this unnoticeable coating prevents heat loss or gain. The coating helps the window to insulate better.

Double Glazed

Double glazing of the window’s glasses reduces heat transfer. It is known to provide high-quality thermal performance. Windows that are double-glazed are best to have for your home’s energy assessment program. U-value is the measure of thermal transmittance through a structure. A lower U-value means better heat resistance. Double-glazed windows have a better U-value measurement with only 1.8. Far from single-glazed clear windows that measure up to five U-value.

Window Frames

Window frames also have their role in energy-efficient windows. Frames made of timber, uPVC, or composite aluminum provide better insulation and thermal performance. Low U-value frames complement the energy-efficient glasses, reducing the whole window U-value.

Strong Sealant

Great insulation is the number one quality of an energy-efficient window. In order to have good insulation, the window sealants should be strong against adverse weather. Without air and temperature leakage, energy can be preserved inside your home. Tight window seals are important for your home’s energy efficiency.
