What is : Low-E Coating

What is Low-E Coating?

Low-E coating, short for low emissivity coating, is a thin, virtually invisible layer of metallic oxide applied to the glass surface of windows and doors. This coating helps to control the amount of heat and light that passes through the glass, making it an essential component in energy-efficient homes.

How does Low-E Coating work?

Low-E coating works by reflecting heat back to its source. In the winter, it reflects heat back into the room, keeping it warm and reducing heating costs. In the summer, it reflects heat away from the room, keeping it cool and reducing the need for air conditioning.

Types of Low-E Coatings

There are two main types of Low-E coatings: hard coat and soft coat. Hard coat Low-E is applied to the glass while it is still in a molten state during the manufacturing process. Soft coat Low-E is applied in a vacuum chamber after the glass has been formed.

Benefits of Low-E Coating

Some of the benefits of Low-E coating include improved energy efficiency, reduced UV exposure, increased comfort, and lower energy bills. It also helps to reduce condensation on windows, which can lead to mold and mildew growth.

Cost of Low-E Coating

The cost of Low-E coating can vary depending on the type of coating, the size of the windows or doors, and the manufacturer. However, the long-term energy savings and increased comfort make it a worthwhile investment for many homeowners.

Installation of Low-E Coating

Low-E coating can be applied to new windows and doors during the manufacturing process or added to existing windows through a retrofitting process. It is important to hire a professional to ensure proper installation and maximum energy efficiency.

Maintenance of Low-E Coating

To maintain the effectiveness of Low-E coating, it is important to clean the glass regularly with a mild detergent and water. Avoid using abrasive cleaners or materials that could scratch the coating and reduce its efficiency.

Conclusion

Low-E coating is a valuable addition to any home renovation project, offering energy savings, increased comfort, and protection against UV rays. Consider incorporating Low-E coating into your next window or door upgrade for a more efficient and sustainable home.
