Aerogel - Light Weight Concreted

Aerogel & Concrete - G.tecz developed a cost-effective and easy to handle ultra light weight concrete system that includes aerogel powder or granulate. Like all our other materials, we can vary density and mechanical properties as well as thermal coefficients regarding the requirements of the structure or application.




The simple diagram is showing the relation of one type of aerogel-concrete we developed. The interesting part here: due to the usage of a nano optimized Quantz matrix, the compressive strength and the flexural strength are higher compared to competitive concrete materials.   Next to high strength and very good insulation factors, the properties regarding environmental influence as ice and defrosting, acid rain and so on are extraordinary - No damages appeared while all of our tests.


These specifications are representing TWO of millions of solutions. By adapting the concrete formulation the mechanical parameters can be changed.

Example 1:

  • Compressive strength: 3 MPa
  • Lambda: 0,08 W/mK
  • Density: 450 kg/qm

Example 2:

  • Strength: 4 MPa
  • Weight: 750 kg/qm
  • Lamba: 0.,09 W/mK
  • U Factor (Wall): 0.22 W/(MK2)
  • ENEV 2009 proofed


  • Pre-Fab wall or building elements
  • Walls, Foundation, Balconies, ...
  • Insulation Plaster


When taking about costs, the overall costs for a product should be discussed first. By using Aerogel concrete for pre-fab wall systems, the whole structure and wall section will change including the usual additional insulation and plaster that is necessary to get the required insulation factor.


With Aerogel concrete

- the thermal insulation system is not required anymore.

- the additional plaster is not required.

- Wall sections can be thinner > More space to build or lease.

- labour costs and building costs will be decreased.

- ... and more advantages.
