Project Outcomes:
Technical Specs. & application
Along with being a lightweight, AAC has the following advantages over traditional bricks:

  • Thermal insulation
  • Structural strength
  • Density
  • Fire resistance
  • High sound reduction index
  • Being light weight saves cost & energy in transportation and labour expenses.
