Subslab Thermal Insulation of an Industrial Hall in Ócsa 

The Energocell® foam glass granules were used for the thermal insulation under the slab of an industrial hall of 2200 m², developed by HORAÉP Kft. for Eurochamp Hungária Kft. (the investor). The 35 cm thick loose granule layer resulted in a 25-cm layer after compaction at 1:1.4, on which 20 cm of stone rubble was placed, to reach the adequate load-bearing capacity. The stone rubble also protects mechanically the foam glass, therefore circulation with heavier vehicles (concrete mixer) during construction is allowed on the bedding, and the use of a concrete pump can be avoided.

The Energocell® foam glass granules were compacted with a road roller on the larger continuous surfaces, and with a vibratory plate near the service installation pipes.
