Floor Refurbishment Works in the Sándor-Metternich Castle in Bajna

In September 2018, as part of the national castle and palace renovation program, the restoration of the Sándor-Metternich Castle in Bajna has been launched, and it also became the first historical building renovation project of Energocell® in which the foam glass granules were used as filling material of the vaulted ceiling. The developer chose the Energocell® granules over other filling materials, because of their light specific weight (150-175 kg/m³) and cost-efficiency. The vaults required a 15-70-cm foam glass layer, that was incorporated and compacted by 10% with a 50-kg grass roller. As seen in the pictures, covering of the surface with OSB boards is recommended to facilitate circulation.
