Silka calcium-silicate blocks, thanks to their material density and compressive strength, offer excellent sound insulation, strength and load-bearing capacity. They are used for the construction of all types of buildings, but the most frequent application is in positions where a high degree of noise protection is required. Thanks to their material density and compressive strength, even the thinnest walls built from Silka blocks offer exceptional acoustic insulation. They are made from natural mineral raw materials, are fireproof (class A1), weatherproof, strong and durable.
