Air lime plasters are indispensable in building biology
No other wall coating has comparable building biology and physical properties to mineral lime plaster and creates such a pleasant, healthy indoor climate by absorbing nitrogen oxides and volatile organic compounds (VOCs) and balancing the humidity in the room.
This is why lime plaster is becoming increasingly important in new builds and renovations. Especially when children live in the household, the topic of "healthy living" is increasingly taking centre stage. In terms of health and environmental compatibility, pure mineral lime plaster is the ideal building material. Due to its natural properties, it is extremely valuable in terms of building biology and building physics.
Our air lime plasters have long been put through their paces by one of the best institutes in the field of building biology. The intensive laboratory work, lengthy tests and results of decades of experience have paid off.
An expert report confirms the functionality of our gräfix lime line on a purely natural basis and is proof of quality and earned trust.
