Lightweight concrete

For building lightweight warm structures, lightweight concrete with Stikloporas expanded glass is an excellent choice.

Why lightweight concrete with Stikloporas granules?

  • Helps prevent cold bridges when moisture and cold get into the foundation.
  • The products weight reduction up to 60%.
  • The compressive strength is 5.4 N/mm2.
  • Material density – 950 kg/m3;
  • Thermal conductivity, W/(m K) – 0.09.
  • Water absorption – from 2 to 4%.
