The “POROTON®-T7®“ by Schlagmann is a new, innovative and very special brick. The natural volcanic rock Perlit is brought into the chambers of the brick. Thus, the thermal insulation is 50% higher than with standard bricks. The large-format bricks together with the processing system V.Plus enable a fast, easy and secure wall mounting. The weight is lower than that of standard bricks; by the lateral teeth POROTON®-T7® can be gripped securely. The manufacturing of the bricks is done according to the international energy management system DIN EN ISO 50001.
