Tempered Glass in Your Apartment

What is Tempered Glass?

Glass that has been controlled thermally or chemically treated to increase strength in comparison to untreated glass is known as tempered or toughened glass. Tempering compresses the exterior surfaces while tensing the interior. Due to these tensions, when the glass breaks, it fragments into tiny granular particles rather than sharp shards like regular annealed glass. The chances of getting hurt are lower with the granular chunks.

Compared to annealed glass, tempered glass is around four times more robust. As a result of the inner layer’s greater contraction during manufacture, the glass’s surface experiences compressive stresses counterbalanced by tensile stresses within the glass’s body.

How is Tempered glass made?

Thermal Process:
Thermal tempering can create tempered glass from annealed glass. The glass is placed on a roller table and passed through a furnace that heats it to about 1,148 °F, significantly over its transition temperature of 1,047 °F. After that, the glass is cooled with forced air draughts while the interior is allowed to flow freely for a little period.

Chemical Process:
Glass is tempered by the chemical process by exchanging the sodium ions on the glass surface for potassium ions and submerging the glass in a solution of molten potassium nitrate. Chemical toughening requires compressing a surface layer of glass at least 0.1 mm thick. Compared to thermal tempering, chemical toughening increases hardness and can be used on glass products with intricate shapes.

History Of Tempered Glass:
The earliest method of tempering glass by quenching almost-molten glass in a hot bath of oil or grease was created by Francois Barthelemy Alfred Royer de la Bastie (1830–1901) of Paris, France. The technique was patented in England on August 12, 1874.

Advantages of Tempered Glass?
Greater Strength
There are several building applications that require the tempering process which makes the glass four to five times stronger and safer than annealed or untreated glass. Fully tempered safety glass is often used for applications where safety is desirable, because of its break pattern or when significant additional strength is needed to resist wind pressure, thermal stress, or both.

Better safety
The fact that tempered glass was created with safety in mind gives it a significant benefit over annealed or “regular” glass. Tempered glass shatters into tiny, comparatively safe granular fragments as opposed to annealed glass, which shatters into larger, more dangerous shards.

Better Hardness
Tempered glass is produced using a thermal tempering technique that significantly increases its strength compared to regular glass. Strong gusts, direct hits and bumps, and small explosions cannot break tempered glass.

Better Heat Resistance
The maximum temperature tempered glass can withstand is 470 degrees Fahrenheit. Tempered glass is perfect for use in kitchen appliances, where it will likely be exposed to heat frequently or quick changes in temperatures.

Better Clarity
Tempered glass is extremely robust, although its clarity is unaffected by the tempering process. Tempered glass works well in windows, glass doors, and exhibition cases because it is transparent and optically clear.

Good Adaptability
Tempered glass can be used practically anywhere glass is required. In addition to a seamless cooktop base, it makes a beautiful and reliable frameless shower door and a clear smartphone screen cover.

Better Scratch Resistance
Tempered glass is scratch-resistant and thermally strong, thanks to the production process. Because of this, tempered glass is a great material for windows in cars, kitchen appliances, and mobile screens.

Lots of Patterns and Designs
Clear, frosted, etched, stained, and patterned tempered glass are all options. It comes in various patterns and designs to meet your demands.

Disadvantages of Tempered Glass?

  • Glass must be cut to size or pressed into shape before being tempered.
  • Glass cannot be reworked after being tempered.
  • The glass edges must be polished, and holes drilled before the glass is tempered.
  • Due to the glass’s balanced stresses, any damage will eventually break the glass into smaller pieces than a thumbnail.
  • The glass is most prone to breaking when it sustains damage at its edge, with the highest tensile stress. However, it can also break if a hard impact occurs in the center of the glass pane or if the force is concentrated.

Uses Of Tempered Glass?

Apartment or Home Interiors:
Apartment interiors make extensive use of tempered glass. Tempered glass railings, frameless shower doors, glass tabletops, glass shelves, cabinet glass, tempered glass windows, and glass for fireplaces are a few examples of common household furniture and appliances that use tempered glass.

Building Exteriors:
Tempered glass is utilized in structures for structurally loaded applications, unframed assemblies (such as frameless glass doors), and any other application that could be hazardous in the case of a human impact. Building facades, glazed glass exteriors, skylights, glass installed near stairways and doorways, large windows, windows that extend nearly to the floor, sliding doors, elevators, fire department access panels, and glass installed close to swimming pools are just a few of the situations where tempered or laminated glass is required by building codes in the United States.

Appliances:
The term “rim-tempered,” which is used in the food service industry, denotes the tempering of a small region, such as the rim of a glass or plate. However, some specialized manufacturers provide a fully tempered/toughened drinkware option that might offer more advantages in the form of strength and resistance to thermal shock. In some nations, these items are required in places with higher performance standards or where heavy use requires safer glass.

Other Uses:
To prevent shattered glass from being used as a weapon, bars and pubs, particularly in the UK and Australia, have increased their use of tempered glass.

Hotels, bars, and restaurants can use tempered glass items to lower breakages and raise safety standards.

Automobile:
When strength, temperature resistance, and safety are crucial, tempered glass is employed. For instance, passenger cars must meet all three criteria. Since they are kept outside, they are exposed to seasonal temperature variations and continuous heating and cooling.

Additionally, they must survive minor hits from car accidents and road debris like stones. Tempered glass is utilized so that, in the event of a break, the pieces are blunt and largely harmless because big, sharp glass shards would provide an additional and intolerable risk to passengers. While side windows and the rear windshield have traditionally been composed of tempered glass, the windscreen or windshield is now constructed of laminated glass, which won’t shatter into fragments.
