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.
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.
Take a look at our technical sheet below for the product.
- best thermal insulation characteristics of the market, the heat transfer coefficient U up to 0.11 W/m2K
- it can replace up to 36 cm of thermal insulation
- with its thermal insulation properties it can replace a solid brick wall up to 7 m thick
- integrated insulation protected by ceramic
- a comprehensive system solution for the building envelope in a single-layer structure
- they meet the recommended values for passive and zero-energy houses with reserve
- solid, safe structure
- natural water vapour permeation – the brickwork breathes
