Concrete wall
Isospan
Conventional concrete and brick walls must be insulated and finished to meet statutory values for sound and thermal insulation. This means valuable working time and expensive materials. Isospan blocks, however, have a sound reduction index of up to 61 dB. Brick walls with the same wall thickness cannot meet the sound level difference of 55 dB between the rooms of living units, which is required in accordance with ÖNORM standards. The same applies to the minimum standards for heat protection. For example, it is necessary to apply a heat insulation composite system to exterior walls made of prefabricated heavy concrete parts due to their lack of thermal insulation capabilty.
