Lightweight filling on the roof terrace of the Hungexpo CK hall
The Hungexpo project needs no introduction, it is one of the largest investments at present in Hungary. On the roof terrace of the CK building, on a 2000 m2 surface 500-m3 foam glass granules were used as a light fill. Thanks to the low specific weight of 150-175 kg/m3 the loads imposed by the material on the roof slab are quite low.
The roof layer structure:
bedding layer - 5 cm
compacted Energocell foam glass layer - 15-25 cm
XPS thermal insulation - 22 cm
bitumen waterproofing - 2 layers
slope concrete - 5-15 cm
