The heat diffusion coefficient values “U” are given with plasters for the production plant in Hevlín at the strength 8 MPa or 10 MPa and thermal insulation mortar or mortar for full-area thin joint Heluz with ground bricks, if not mentioned otherwise.

DESCRIPTION

For single-layer perimeter walls of zero-energy, passive, low-energy and energy-efficient buildings.

FAMILY 2in1 ground bricks have the best thermal insulation properties on the market in comparison with other materials for single-layer masonry. Filling the cavities of these bricks with polystyrene increased their thermal insulation properties by 40% while maintaining their water vapour permeability. The FAMILY 2in1 bricks in widths of 440 mm and 500 mm meet the recommended values for passive houses without additional insulation.
