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%.
