If you are in the market for new windows or window replacements, it can be a little confusing. You'll find that there are many types of windows to choose from for your home. It's hard to make a selection if you’re not familiar with the technology or materials available.

One question that we get a lot at The Window Authority of Houston is, "What's the difference between Low-E glass and tempered glass windows?"

Well, the answer is a lot.

In fact, these windows are both manufactured to serve different purposes. Let's take a look at each product.

The Strength of Tempered Glass Replacement Windows

You may have heard of tempered glass before when referring to car windows. Many vehicles use tempered glass in the side windows because it is safer than other non-tempered windows. Why? Tempered glass windows are stronger and more resistant to breakage. When they do break, the glass crumbles into tiny, rounded pieces rather than long shards.

How does tempered glass work?

The secret of this type of glass lies in how its manufactured. A sheet of annealed, slowly cooled, glass is heated to high temperatures, and then quickly cooled. The fast cooling process forces the surface of the glass to harden before the interior. As the inside of the glass cools it creates tension against the already hardened surface. When the glass breaks the stored tension causes it to burst into thousands of tiny pieces.

Tempered glass replacement windows are a wonderful option for areas of the home where glass breakage is more likely or could cause more harm to your family. For instance, it works well in or around:

  • Bathrooms
  • Pools
  • Conservatories
  • Patio Doors

The Energy Efficiency of Low-E Glass

Low-E glass is being used by many window installers in energy efficient products these days. It is glass that is coated with metallic oxides before installation. Low-E coatings don't alter the structure or strength of the existing glass pane.

Additionally, Low-E glass coatings reflect ultraviolet (UV) and infrared rays away but allow other types of light to enter the glass and home. As UV light is the type of sunlight that causes the most heat gain, this simple window coating is very effective at keeping your home cool in the summer.

You may be wondering if it's possible to have both Low-E and tempered glass in one product?

The Window Authority of Houston is happy to help homeowners with designing their replacement windows to include tempered glass and a Low-E coating. You can enjoy the benefits of both strength and energy efficiency at the same time.
