Ytong thermo is characterized by excellent thermal insulation properties. It is intended for the construction of external walls, in one layer, without the need for additional thermal insulation. Due to the low coefficient of thermal conductivity (λ10dry=0.084 W/mK), an exceptional energy efficiency of the building is achieved. Construction with Ytong thermo blocks in the Ytong construction system enables construction that meets the strictest standards in terms of energy efficiency. The Ytong thermo block is made from completely natural materials and is environmentally friendly. Fire reaction class A1.
