HOW MUCH DO YOU KNOW ABOUT TEMPERED GLASS AND STANDARD GLASS?

So, tempered glass is five time harder than standard glass with the same thickness, and also more expensive. What more? Find out now

TEMPERED VS STANDARD

Manufacturing procedure:

To make glass, the mixture of soda ash, lime and sand is melted at very high temperatures (more than 1650 C). After it has been formed and cooled, people reheat and cool it once again. This process, called annealing, makes these two type different.

Tempered glass is cooled rapidly, resulting in its additional strength, resistance to thermal stress, and impact resistance. Fully tempered glass are at the 10000 psi (pounds per square inch) level. Tempered glass is also called toughened glass, because they are now one of the most force-resisting glass.

Standard glass, on the other hand, is cooled slowly. This is the reason why it is ,uch more fragile, its surface compression is only at 3500 psi level.

 Broken state and applications:

Tempered glasses have more impact resistance, but break completely when the forces come unbearable, leaving no intact areas. They will shatter into millions of little pieces, somehow end up protecting people involved (they will have a few scratches, but it is okay). Because of this, they are preferred in structures where safety is the top prior. Standard glass can be cut to size or pressed into shape after it is processed. If an application requires, its edges can be polished or holes drilled into it. Tempered glass cannot be reworked after it is tempered. Attempts to cut or drill into a pane would result in it shattering completely, that is why the task of cutting or dyeing glass must precede the annealing process. Tempered glass is also called safety glass, used to create car windows and glass doors because it is tougher than any kind of standard glass (you know, to be safer). But now, in applications requiring the highest degrees of safety, laminate glass is now more commonly used. Laminate glass is made by two layers of glass pressed together with coated plastic in between, producing a much tougher glass. In situation of extreme force, laminate glass will crack, but not shatter.

Standard glass will break in the certain area crashed, resulting in cracks or a hole in just one location, and leaving the rest of the pane in one piece. At some points, standard glass is considered to give greater security, as parts of a glass can remain safe and sound even after another section is broken. But the problem will get super huge if so many holes connected in one pane appear, the whole piece will break into large and sharp fragments, putting everyone in contact with it at extreme risk.  Standard glasses are still widely used at many applications because they are cheaper, and the requirements are not in need of tempered glasses.

Tempered glass should not be used where building codes require wired glass for fire-spread resistance. When using tempered glass in fireplace screens, provisions must be made for expansion and edge insulation.Also, tempered glass should not be used, alone, where the objective is to provide security against forced entry or bullet passage. Combinations of standard and tempered glass can be effective barriers against forced entry and bullet impact, if they are in proper design and construction.

Tempered glass has more heat resistance and scratch resistance than standard glass. About the appearance, however, it does not appear any different than standard glass. The two types of glass are made in a variety of sizes and thicknesses and can be colored and tinted as you like.
