What are the advantages of Porotherm bricks?

Porotherm bricks are perforated clay brick. It is perforated horizontally or vertically.

Size: 400 x 200 x 200mm

It is a natural brick which has thermal insulation made from coal ash, natural clay and rice husk.

Following are some advantages of porotherm bricks:

  1. Very good strength: compressive strength of brick is greater than 3.5 mm. The presence of terracotta gives higher strength to the bricks.
  2. Thermal insulation; due to its perforation it has high thermal insulation characteristics.
  3. Durability: perforated bricks have a water absorption ratio is around 15% which reduces the probability of cracks, dampness and shrinkage of walls. Also due to the high compressive strength and characteristics of fire resistance also make it highly durable and long-lasting.
  4. Economical: due to the method of perforation it reduces the manufacturing cost which saves energy and operating cost. This type of bricks balance the inner temperature with an outer temperature and avoid the usage of AC or heater in summer and winter respectively.
  5. Friendly to the environment: this brick can be recycled. all the materials for manufacturing of these bricks are natural which does not cause any allergic effect to the environment.
  6. Increases construction speed: for the construction of the wall made with porotherm bricks does not need curing. Due to its lightweight handling is easy and quick which reduces effective labour time.
  7. Porotherm bricks should be cut with a chisel and can be fixed at a fissure cracks. This breaks n sure a dry and clean site with fast construction.

Porotherm bricks give a plethora of advantages over normal bricks :

  • Lightweight (60% lighter than normal bricks)
  • Environment-friendly
  • High compressive strength so high as 7 MPa.
  • Very low water absorption
  • Thermal and sound insulation (50% better than normal bricks)
  • Resistance to carbon dioxide attack
  • A lot of natural waste products used including silt from water treatment tanks, coal ash, fly ash, terracotta, rise husk and sawdust.
  • Easy workability for electrical and plumbing fittings
  • Fire resistance
  • Speedy construction

So, basically by the name it indicates some thermal properties, which for this brick is good thermal insulation.

Other advantages are like light weight due to porous structure and sound insulation.

Economically, these bricks saves power in terms of cooling hence saving your electrical bill.

Porotherm bricks provides a comfortable living environment due to its thermal efficiency and acoustics efficiency.

These bricks are light weight which helps in maintaining a steady production during construction.

They are made up of entirely natural ingredients such as rice husk ash, sawdust, coal, ash etc. Porotherm bricks are approved as eco-friendly by GRIHA (Green Rating for Integrated Habitat Assessment) and IGBC (Indian Green Building Council).

It is highly fire rated as it is burnt at 1000 degree Celsius. So during fire it provide sufficient time for evacuation.

Porotherm bricks are low water consuming when compared with conventional bricks.

Moreover, they are recyclable and reusable and do not harm the environment.
