The report tells how the requirements level for heavy clay products was successfully updated to a technically and economically feasible niveau. Now, whenever technical progress allows, moderate adaptations can be implemented. Explained is how the interests of other important disciplines in housing construction, e.g., thermal insulation and statics, can be conciliated with structural soundproofing.
