Benefits

WHY VAJRA AAC BLOCKS ?

Vajra Building Products is the industry’s leading AAC Blocks Manufacturers and durable concrete materials. Vajra AAC Blocks is highly considered over conventional Construction Brick and Mortar methods.

This Concrete Block enables the engineer to optimize the time involved in completing a project.

Weather & Earthquake Resistant

The impact of earthquake forces on a structure is proportional to the weight of the structure. Hense, VAJRA AAC Blocks provides excellent resistance to earthquake forces.

Economical

VAJRA AAC blocks are lighter than standard bricks and blocks, therefore they reduce thedead weight of the building. This will bring about significnat savings in steel and concrete used.

Long Lasting

VAJRA AAC blocks are not vulerable to water damage as compared to other construction materials. They can even withstand harsh climatic conditions, thus reducing the rate of deterioration, this in turn gives you increased value for your investment.

Excellent Thermal Insulation

VAJRA AAC blocks has a very low thermal conductivity resulting in very high thermal energy efficiency. This results in a significant cost savings in the heating and cooling.

Cost Component Saving in Component Estimated Impact on Project Cost Explanation
Mortar Material 60% 1% Vajra AAC Blocks are 9 times the size of conventional bricks, resulting 1/3rd the number of joints. Thus an overall mortar saving of up to 65%.
Plastering Material 35% 2% Exceptional dimensional accuracy & smooth surface eliminates need of three coat plaster walls and allows for a final 6mm skin coat (putty / gypsum plaster)
Breakages 65% 1% Breakage in Vajra AAC Blocks are less than 3% as compared to 15% in bricks
Structural Material 15% 6% Being light weight, Vajra AAC Blocks reduce dead weight of the building. This translates to design lighter structures leading to reduction in steel and concrete by up to 20%
Increase in Floor Space Area 2% 4% Due to exceptional thermal insulation and weather barrier properties, it is possible to use thinner blocks, which result in increase of carpet area
Savings in Capex (for HVAC Systems) 30% 0.3% Vajra AAC Blocks have excellent insulation properties, which results in saving of capex of HVAC systems
Savings in Power Consumption 12% 0.2% Vajra AAC Blocks reduces usage of lights & power infrastructure like transformers, DG sets, cable sizes overall electricity charges
