Interio blocks are characterized by high compressive strength (3.0 N/mm²) and precise dimensions, which makes them suitable for the quick, easy and simple construction of partition walls. The precise dimensions of the Interio blocks ensure an extremely flat wall surface, which further facilitates the completion of the work. They are easy to process and create a minimum amount of waste. They are used for the construction of internal partition walls. Due to their low weight, quick and clean construction and easy processing, Interio blocks are irreplaceable both in new construction and in the adaptation and additions of existing buildings. Fire reaction class A1.
