Tinted glass building material is simply colored glass. A certain type of ion is added to the normal glass mix to produce colored glass. In tinted glass, color doesn’t affect the properties of the glass.

For example, iron oxide gives green and Sulphur gives blue color shades in glass manufacturing.

8. Toughened Glass

Toughened glass is used extensively throughout the industry for its ability to resist breaking, also called safety or tempered glass. If it breaks, it does so into much smaller called ‘safer’ pieces as opposed to large shards (like float glass) Toughened glass is typically used in home interiors such as the kitchen (for its heat resistance), shower screens, glass balustrades, and swimming pool fencing.

It can also be utilized in laminated panels where extra safety precautions should be taken.

9. Chromatic Glass

 Cromatine Glass

  • This glass is utilized in ICUs & meeting rooms, chromatic glass can control the transparent efficiency to protect the interior from daylight.
  • Chromatic glass has maybe electric lamination(electrochromic), thermos-chromatic (heat-sensitive lamination), or photochromic (has light-sensitive lamination).

10. Extra-clean / Self-cleaning Glass

Glass blocks or Hollow glass wall blocks are manufactured as two separate halves and, while the glass is still molten, these two pieces are pressed together and annealed. The resulting glass block will have a partial vacuum at the hollow center.

Hollow glass wall blocks or Glass bricks usually provide visual obscuration while admitting light from the outside of the room.

Advantages of Glass

The following are major advantages of glass,

1. Transparency Is Good

Glass is a unique transparent material that allows light to pass through it so that the objects behind the glass are visible clearly.

This property of glass allows you to connect with the outer world visually, even when the door and windows are closed, it enables the light to flow in. Thus, it saves energy and reduces electricity bills.

2. Dust-proof and Waterproof

Glass has a glossy and smooth surface, so it becomes dustproof and can be cleaned efficiently. Unlike other materials, it is easy to maintain.

Another advantage is, it is waterproof. Due to such dual advantageous benefits of glass as the dustproof & waterproof material, it is mostly preferred in areas often clad with dust and sand in the air.

3. Color Availability

Glass is available in a wide range of colors, and when we combine the glass sheet in laminated or insulated units, it changes color and enhances the beauty of its appearance.

Laminated glass can be made with a wide range of colored interlayers to provide exceptional lighting effects.

4. Aesthetically Appealing

Glass enables an ideal way to show off a product aesthetically. The glassy effect it can make the structure look more stunning, and sophisticated and adds beauty to the building.

5. Recyclable

The other benefits we can gain from glass recycling are, energy can be saved, it is cost-effective, it reduces water pollution and air pollution to a certain extent and it also conserves natural resources, etc.

Glass material is 100% recyclable, and it does not degrade during the recycling process. Thus, it can be recycled for more time without compromising on quality or purity.

6. UV Stable

Glass is UV stable since it is not affected by ultraviolet radiation and hence cracks, discoloration or disintegration will not occur.

7. Weather and Rust resistant

Among all of the materials utilized in building, glass is anti-corrosive material, and only under certain conditions, the glass is chemically attacked.

Glass is fully weather resistant. It can give greater support against the effects of the wind, rain, or the sun and can retain its appearance and integrity in most of the given conditions.

8. Easily Molded

Glass building material is a transparent, hard material that can be easily molded into desired shapes. It is manufactured by the application of heat into the sand.

So, glass can be drawn and pressed to any desired shape and thus used for general glazing purposes in buildings, shop fronts, building doors, windows, and workshops.

9. Insulator of Electricity

Glass building material is an excellent insulator. It does not readily conduct electricity. It makes sure that you are safe from any electrical hazards.

Due to these unique and advantageous properties, glass can be used for the formation of ceiling lights, decorating wall lights, and various other electrical appliances.

Disadvantages of Glass

The following are major cons of glass,

1. Cost Is High

The manufacturing of glass is a highly energy-consuming process due to the high temperatures required for processing the raw materials.

Using glass in a building increases the total cost of security & privacy because of the transparency that it offers.

2. Glass Is a Brittleness

Glass is a stiff, rigid, and brittle material. When glass is subjected to stress, it fails/breaks without any significant strain. Cracked pieces of glass may be very sharp, and the chances of injury to humans become very high.

3. Impact Resistant Is Low

The Glass is less resistant against impact load, so the capability of the glass to withstand an immediately applied load is very poor. It will immediately break under impact.

4. Corrosion Due To Alkali Solution

The Glass is affected by alkalis ions. Alkali solution dilutes a glass surface, and if the supply of alkali is more, this type of corrosion takes place at a uniform rate.

5. Unsafe For Earthquake-prone Areas

Structures that are located in earthquake-prone areas require to be specially designed to take horizontal loads and movements. Material of glass is more brittle than other materials, hence it tends to break or collapse quickly.

6. Maintenance Cost Is High

In more dust-prone regions & humid areas, dust particles will stick to the glass surface and hence it will not only look dirty and shabby but the internal lighting, as well as transparency, will be poor.
