Tempered VS Annealed Glass

1APPLICATIONS
This is one of the most common questions that we get at Floyd Glass & Window. There are many applications for tempered glass. It is used commercially in glass doors that have no frames. The windows in the passenger sides of cars use tempered glass to increase safety. Annealed glass can be used in many situations. If a window is in a low-traffic area where safety is not a concern, annealed glass may be the best option because it remains cheaper than tempered glass. But many states have adopted building codes where tempered glass is required. For instance, any glass window within two feet of an open door must be tempered.
2ANNEALED GLASS
When glass is annealed, it is slowly cooled to relieve any internal stresses. When not annealed, glass is more likely to crack when exposed to temperature changes. Unlike tempered glass, traditional annealed glass will break off into large, sharp shards when broken. This can pose obvious safety risks. Care should be taken when choosing locations to install annealed glass. Annealed glass is a great fit for table top glass, cabinet door glass and basement windows.
3TEMPERED GLASS
Tempered glass is also called toughened glass. Unlike annealed glass, tempered glass breaks into small, square pieces when broken. This makes it less likely to lacerate a person that comes into contact with it. Tempered glass is one of the hardest types of glasses, several times harder than most others, including annealed glass. Creating tempered glass involves the use of chemicals and heat to give it its properties. These treatments balance the internal stress rating of the glass. The downfall of Tempered Glass (as you will see in the video below) are the edges of the glass. Because of the heating and cooling process that the glass goes through to become tempered, the edges are the weak point. Meaning, if metal comes in contact with the glass it is highly likely it will blow: no one will get hurt, but you will now be in the market for a new piece of glass. Tempered Glass also can not be cut. Once it starts getting cut, it will explode into a thousand pieces. Frameless Shower Doors, Windows within 18” from the ground, Windows above a bathtub/Shower, glass within a certain distance of a doorway all must be tempered by State Law. Because of the edges, Floyd Glass & Window recommends Annealed glass for most table tops.
4COST
Tempered glass is more expensive than annealed glass because it has to go through more processes in its creation.

General Questions

1WHATS A STANDARD THICKNESS FOR A TABLE TOP?
1/4" Thick Gglass is the most common thickness. While some people like to use 3/8" thick or even 1/2" thick glass. Each application is different and one of our experienced technicians can help you decide on the exact thickness you would need for your glass top.
2HOW LONG DO REPLACEMENT WINDOWS TAKE TO GET?
On average our vinyl windows take 2 to 4 weeks. Fiberglass and aluminum windows take between 3 to 6 weeks. Lead times depend on how busy each manufacturer is and can change at any given time.
3IS THERE OTHER TYPES OF OBSCURE GLASS FOR WINDOWS AND SHOWERS?
Yes, there are anywhere from 20 to 40 different types of glass patterns for windows and shower enclosures. We have brochures and samples in our showroom for our customers to look at.

Custom Glass Edges

flat polish

Flat Polish

As the name implies, a flat polish is a flat edge with a small 45 degree chamfer on the very top and bottom. For custom made 1/2″ and thicker Glass Table Tops, a flat polish is recommended. It is economical and is the best way to show the thickness of the glass. A Flat Polish is also called a “Machine Polish.” You will see this most commonly on pieces made in bulk.
