More information about the product can be found in the current Pricelist or the Product Catalogue.
Thermal insulation ground bricks filled with expanded polystyrene laid on system thin-layer mortar designed for protected single-layer perimeter brickwork of nearly zero-energy buildings.
FAMILY 2in1 ground clay blocks have the best thermal insulation properties on the market in comparison with other materials for single-layer masonry. Filling the cavities of these clay blocks with polystyrene increased their thermal insulation properties by 40% while maintaining their water vapour permeability. The FAMILY 2in1 clay blocks in widths of 440 mm and 500 mm meet the recommended values for passive houses without additional insulation.
