Yes, both are different. Tempered glass is made by heating annealed (normal float ) glass above 6000C and then fast cooling, this makes the glass 4 to 5 times stronger than normal glass. Tempered glass breaks into small circular fragments, while normal glass breaks into sharp pieces.
Laminated glass is made by laminating two sheets of glass with a PVB (Poly Venyl Buteryl) sheet in between, in a clean environment. The sandwich is heated and pressed. Apart from safety, laminated glasses are also used for sound insulation.

Who invented laminated glass?
Laminated glass was invented by Libby-Owens-Ford. It was made for the auto industry
We have a 3/8" thick glass coffee table top which we want to shorten. We are told if the glass is tempered- no can do. True any way to tell if a piece of glassis tempered?
You can not cut tempered glass because once a piece is broken the whole glass shatters. Tempered glass is safer because it breaks into tiny pieces rather than sharp edges like regular glass. The only way to tell if a glass is tempered is to break the glass or use a polarizer to detect stress waves. You will see stress waves in tempered glass verses regular glass. Hope this helps.
Is there space between the layer in a laminated glass so that total internal reflection can Occur?
No.
What does laminated glass weight?
If you are in the US, then glass weighs 155lbs/ft³. If you are not in the US or you want to use metric, you will have to do a conversion. 155lbs/ft³equals approximately 1.52lbs/ft² at 1/8" thickness Polyvinyl Butyral or PVB weighs .085lbs/ft² at .015" thickness. Since laminated glass is two sheets of glass "sandwiching" a sheet pf PVB, we can calculate the weight of a square foot of laminated glass consisting of two lites of 1/8" glass plus the weight of the PVB interlayer - in this case, .015". glass + interlayer + glass = 1.52lbs + .085lbs + 1.52lbs = 3.125lbs/ft² A little bit of basic arithmetic and you can get the weight of any size or thickness desired.
Can laminated glass be tempered?
Tempered glass can be laminated, but laminated glass cannot be tempered.
Can i cut or drill a hole in laminated and tempered glass?
Laminated glass and tempered glass are not necessarily the same thing. Tempered glass cannot be drilled, but untempered laminated glass could (probably) be drilled. Holes in tempered glass are drilled before tempering.
What type of glass are mainly used on cars?
Laminated glass, used mainly for windshields and tempered glass for the rear and side windows.
Is an auto side window laminated safety glass like a windshield?
No, although the front windshield is usually laminated the side and vent windows utilize tempered glass. This glass can stand up to the daily toil put on it by slamming doors and driving over rough roads.
In cars how does safety glass reduce the risk of injury?
Most if not all new vehicles have two types of glass installed. Laminated, and Tempered. Your windshield is a laminated piece of glass which means you have two layers of glass and vinyl in between them, this allows almost no penetration thru the glass. Tempered glass are the side and back windows. If you were hit on the side of the vehicle would you want this shards of glass flying thru the car like some old house windows?, Tempered windows when shattered break into small pebble like pieces of glass thus making it safer for the occupants.
What are the types of glass they use in cars?
Side and rear uses "tempered" glass. Tempered glass is used because it breaks into small pieces and does not create long, sharp shards which can stab you. Windshields are made of "Laminated" glass, meaning that two pieces are glued together using a clear, sticky material. Laminated glass is used to protect you as well. The pieces are stuck together so that the big pieces don't get loose and fly into your face. The advantage of laminated glass is that it will hold together enough to make it so that you can still see out, so that you can hopefully have a little better chance of controlling your car.
What is density of laminated glass?

What is laminated glass usually used for?
Laminated glass is used in home construction and has many different applications. It can be used for safety and security in windows as glass is normally very easily broken but once laminated it becomes much tougher.
Is temperd glass the same as laminated glass?
Tempered glass is not the same as laminated glass. Tempered glazing is run through a furnace at high high and then quenched. Roller marks are a trademark of tempered glass which give it a wavy characteristic. This is caused from the rollers inside of the furnace. Laminated glass is typicall 2 pieces of float glass with a PVB (polyvinyl butyral) interlayer which is typically .030". The best way I describe the difference of the two types is as follows: Laminated glass is what is installed in the windshield of your car and Tempered glass is typically your door and back glass. Hope that helps. You are correct in saying that Tempered Glass is normally used in Motor Car doors etc. It is also used where there is a chance of the glass being bumped, such as in a Patio Door. The reason is that when Tempered Glass is made, it is heated in an Autoclave and then quickly cooled. This forms different layers of compression and tension in the glass. This enables it to bend far more than normal glass before breaking. This gives it it's 'toughness' although it's actual hardness is not changed. It is because of these layers that tempered glass breaks in it's traditional way, which is into small crystals. In some countries this glass is legal in windscreens but have what is known as 'zone toughening' where the glass breaks into much larger pieces so as to enable the river to still see through it.They are mostly illegal because with the speeds of modern cars you are quite likely to end with your windscreen in your face and all over the inside of the car! You are erroneous in saying that roller marks are a sign of Tempered glass. These marks come from the old 'Drawn Sheet 'way of glass manufacture where molten glass was drawn up between rollers to give it it's thickness. The only way to tell if it is tempered is to look for marks where the glass was gripped when being toughened. Another aspect of toughened glass is that once toughened it cannot be worked on or cut because as soon as the outer skin is broken it shatters! Almost all glass is now made by the 'Float' method where glass is floated out on a bed of molten tin, hence 'Float Glass'. This method produces optically pure glass nearly as good as the older method of polishing 'Drawn Sheet Glass'. All safety Glass, tempered or laminated must carry a visible, sandblasted label stating what it is. Tempered glass can be tinted in manufacture but it does not affect harmful Ultra-violet radiation. Laminated glass on the other hand is made from two or more normal sheets of glass bonded together with a vinyl interlayer. This has the effect of preventing bending, unlike toughened glass. with Laminated glass the interlayer keeps the glass together even when smashed which makes it ideal for use as windscreens and any other application where safety is a problem but where it will not be subject to bangs such as in a patio door. Laminated glass comes in different forms and thicknesses. A windscreen uses two sheets of glass with a standard interlayer or a high impact interlayer which is thicker and can take lot more punishment before being penetrated. The color you get in windscreens comes from the interlayer. High Impact and Multi Laminates are use when extra security is required, such as Banks Jewelry shops etc. Flat Laminated glass with two sheets can be cut and processed, but multi laminate is made cut to size. Another type of multi laminate is bullet resisting which come in different thicknesses depending on what you want to stop. Nineteen millimeter will stop a 9mm bullet but it takes up to fifty millimeters to stop a rifle bullet. These are characterised by having decreasing thicknesses of glass in them; 12mm on the outside going down to 3mm on the inside. Ordinary multi laminate has the same thickness glass throughout. Another interesting type of Laminated glass is 'Sound Reducing Glass'. This has a very soft but thick interlayer. These are used in noisy applications such as airports. One other very important aspect of laminated glass is heat and sun protection. There are many different types (a lot depends on what you want to use it for. I have even seen mini louvres laminated between two sheets of glass) The most common is a metal deposit placed on one sheet (the outside sheet) in a vacuum chamber. this varies in density depending on the requirement. The best is Gold!! These look like mirrors on the outside but have a remarkable effect on temperature. These are of course highly specialised. All laminated glass helps to eliminate harmful Ultra-violet radiation
What type of glass is used for car windows?
Toughened or laminated EDIT: Laminated, annealed glass for the windshield. It will be held to gether by the plastic if broken, and not break into shards to cut the driver and passenger. The other windows are tempered, and break into small cubes that don't cut. Classic cars, like '57s chevys, have laminated glass thoughout. Antique cars , like Model T's, had simple plate glass, it caused serious cuts in an accident
What is the Difference between herculite tempered glass and herculite tempered safety glass?
Herculite tempered glass is a type of tempered glass that has been processed to increase its strength and safety. Herculite tempered safety glass is a specific brand of tempered safety glass known for its durability and resistance to impact. The main difference is that Herculite tempered safety glass is a branded version of tempered safety glass, possibly with additional features or specifications.
What type of material are Corelle plates made of?
Corelle is made of Vitrelle, a tempered glass consisting of two types of laminated glass into three layers. The bonding of these layers gives Corelle its strength, making it thinner and stronger.
