A Quick Guide to Window Glazing

Window glazing improves the thermal or visual qualities of glass. It’s a thin coat that forms a seal along the surface of the material. Depending on the kind of glazing, it can improve a window’s insulation, or filter out UV light from the sun.

Window Glazing

For someone who is not familiar with window glazing, it can be difficult to choose the right glass for your home. That’s why we put together this quick guide to window glazing. Please note that some of the older types are not as energy efficient as modern ones, and in some cases, replacement may be needed.

Heat absorbing glazing

Heat absorbing window glazes use a type of tint that filters out the sun. The tint reduces the amount of UV light that enters the home, which reduces glare. It reflects very little light.

Insulated glazing

Insulated window glazing helps lower U-factor, which refers to the ability of glass to transfer heat. Insulation lowers the amount of heat that passes through the window, controlling the temperatures inside the home.

Low-emissivity coatings

Low-emissivity coatings, or low-e, are a more efficient version of insulated glazing. It’s the type of insulated glass we offer here at Suburban Glass Service, Inc. Low-e uses a very thin, invisible coating of metallic oxide. This material can reduce energy loss by as much as 50%, depending on its thickness.

Reflective coatings

Reflective coatings are great for blocking light from entering the home. It looks shiny and comes in colors such as silver or gold. Reflective coatings are popular for use in high-rise buildings.

Spectrally selective coatings

Spectrally selective coatings are a subset of low-e coatings. It filters up to 70% of heat, while still allowing light to pass through. It’s an advanced type of window glazing that works well for homes in very hot climates.

In old buildings, non-glazed glass is common, which is one of the reasons it’s difficult to cool or heat them. Glazed glass makes all the difference in terms of comfort and safety. For more information on glass glazing, contact us today.
