Coatings Applied On Glass

There are several types of coatings that can be applied on the glass that comes with double hung style of windows. The most popular coatings for glass include:

  1. Low Emissivity Coatings

Low emissivity coatings are usually applied on glass to enhance its energy efficiency. A low emissivity coating works by keeping out infrared rays and allowing light to pass through the glass.

The coatings are available in two options including hard coat and soft coat. A hard coat is ideal for application on a window system with either single or double glazing. On the other hand, a soft coat is only ideal for application on a double glazed window.

  1. Liquid Coatings

Another popular coating for application on glass is liquid coatings. These coatings are applied on glass to prevent glare and UV rays from passing through it. That way, you’ll enjoy a more comfortable temperature in your home, especially during hot, sunny days. Also, blocking out UV rays will protect soft furnishings, curtains, and carpets from fading that results from direct sunlight.

Coatings Applied on the Window Frame

Besides coating glass, you can also apply a coating on the window frame. There are several types of coatings applied on the frame. If your windows are made of aluminium frames, one of the best coating to apply on the framing is a powder coating.
