Tempered glass is sometimes referred to as toughened glass as well. In this article we will examine the qualities of tempered glass and explain its common uses for windows and offer some buying tips. We also will give a comparison between tempered glass and regular glass.
Tempered glass is roughly four times stronger than regular glass. It is meant for applications that may withstand severe pressure that normal glass cannot handle without shattering. It is often known as safety glass because when it does shatter, it breaks apart in tiny square like pieces that are not as sharp and dangerous as regular shattered glass shards which can be pointed, sharp and extremely dangerous during both breaking and clean up afterwards.
Creation of Tempered Glass
Some of you may have guessed that tempered is associated with heat. The true strength is given to glass once it is heated in a chemical type process that changes the composition of the glass and hardens it. The process causes the glass to be able to withstand a lot more pressure and abuse than regular glass.
The actual process is outside the scope of this article, but it has to do with heating and chemically changing the glass properties to make it harder to break and that it breaks up in small pieces that are not likely to be sharp and dangerous when it does break.
One of the most common uses for tempered glass includes vehicle side and back windows for automobiles. The windshield of automobiles however is what is made from what is known as laminated glass and not tempered glass. They use laminated glass because it is shatterproof because of the lamination process.
The laminate used on the windshields doesn’t allow the glass to fly apart when it is broken, instead it is held together so that when it is broken, it splits and cracks but doesn’t come apart. It remains in one piece pretty much anyway.
Other common uses for tempered glass include industrial strength windows and doors and glass doors without frames. If the door is frameless, it needs the extra strength of the tempered glass just to withstand normal use such as opening shutting and the occasional slamming of the door. Bulletproof glass is also constructed from very thick layers of tempered glass.
Tempered glass is said to be at least four times stronger once it goes through the tempering process. The glass is much more common in use where there is a greater hazard of the breaking of the glass being used. The glass is simply stronger and safer than regular glass.
Buying Tips for Tempered Glass Windows
From what we found on the internet, the actual cost of the tempered class by itself isn’t a huge difference for the safety and durability it provides. The question seems to be whether or not there is a need for tempered glass in the home. If you have a particular window that is subject to more stress than usual, then yes, use tempered glass.
If you have lived in a house for 20 years and never had a broken window, then chances are there is not a need for tempered class. Then again if you just want the added security that knowing if the window shatters, people in your home are less likely to get cut in the process or clean up, then you may want tempered glass just for the safety in case something out of the ordinary happens.
Another case where you might want to spend the extra couple dollars on tempered glass is in situation where your windows are subject to severe winds or even hurricanes. While hurricane strength winds may even break tempered glass, it will at least break in a much safer manner than regular non-tempered glass.
That is about all you need to know about tempered glass when thinking about buying it for your home. It is basically only called for in areas where windows are commonly broken and in situations where your families safety is at risk by the possibility of breaking the window and having the broken glass cut someone.
Tempered glass is almost impossible to get a severe cut from. So tempered glass, especially if the option doesn’t cost much more, may be a great investment when thinking of replacement windows in your home.
I don’t think it is necessary to replace all of your regular glass with tempered glass, but if you need replacement windows anyway, why not choose the added security measure for your home and family’s sake? It sounds like a good idea for the right situations.
