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.

Properties of Glass

Glass has 5 main engineering properties due to which utilization of glass has become vast in construction industries;


Transparency is the main and primary engineering property of glass that allows us to see through it. Due to this property glass can be transparent from both sides or from one side only and the other side acts like a mirror.

Work-ability and Recycle Property

Glass has superior workability as it can be molded into countless shapes or blown during melting. Also, any type of glass can be 100% recyclable and used as a raw material in construction.


Glass’s strength is measured by its modulus of rupture value. Glass is generally brittle or tends to break easily but we can make it stronger by adding admixtures and laminates.


This property of glass refers to the visible fraction of light passing through the glass.

U Value

This represents how much heat is transferred through the glass. Insulated glass units provide a low U value.

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

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.


What is self-cleaning glass?

Self-cleaning glass has a special coating that breaks down organic dirt and uses rainwater to wash away the residues. It reduces the need for manual cleaning and is commonly used in hard-to-reach areas such as skylights and high-rise windows.

What is reflective glass?

Reflective glass, also known as mirrored glass, has a metallic coating that reflects a significant amount of light and heat. It is often used in buildings to control solar heat gain, reduce glare, and enhance privacy.

What are the properties of glass?

Properties of glass include transparency, high compressive strength, low tensile strength, brittleness, chemical inertness, thermal insulation, electrical insulation, and the ability to transmit, absorb, or reflect light.

What is float glass?

Float glass is a type of glass produced by floating molten glass on a bed of molten metal, typically tin. It is widely used in architectural applications due to its high clarity and uniform thickness.

What is tempered glass?

Tempered glass is a safety glass that is heat-treated to increase its strength. It is resistant to breakage and when it does break, it shatters into small, less dangerous fragments.
