The maximum compressive strength of the foamglass S3 series plate is 900 kPa and, consequently, they are mainly used as floor and roof insulation. S3 series foam glass can carry medium-sized vehicles and various maintenance machines. The thermal conductivity of the T3 + series insulation is 0.045 W / (m · K). The compressive strength requirements of any application should always be confirmed with a civil engineer to ensure the correct specification of the product.

The interior of the Board consists of foam glass and corresponds to the A1 fire cat, but a thin fleece coating has been added to the front side at the factory, as a result of which the material has a fire Class E.

Foam glass is an insulating material made of almost 100% pure glass, which is obtained during a complex manufacturing process, forming glass frame panels of different sizes. The inside of the panel is formed by honeycombs filled with carbon dioxide (CO2) and sealed. Foam glass is commonly used in buildings where resistance to moisture is important, such as water treatment buildings, swimming pools, green roofs, etc., on high-load roofs such as parking roofs, sun roofs, machine roofs, etc., or for underground floor insulation.


Foamglas S3 foam series insulation is made of specially sorted recyclable glass (- 60%) and natural raw materials such as sand, Dolamite and lime. The material is:

  • Waterproof and moisture resistant
  • Rodent and insect resistant
  • Resistant to chemical compounds, including acid resistant
  • Lightly processed
  • Combustible
  • Impermeable to water vapor
  • Dimensionally stable
  • Ecological
  • Radon insulating
