MC250 Plus

Load-bearing Wall Block MC250+

Blocks for the construction of load-bearing external walls, with an external thermal insulation thickness of 250mm. The blocks are suitable for the construction of nearly zero-energy buildings and passive houses. The “Plus” blocks of the system feature plastic (HDPE) ties, effectively eliminating the possibility of thermal bridging.
