With ecosphere we celebrate the union of glass and mortar: supported by the Federal Ministry of Education and Research (BMBF, Berlin), the paint, plaster and mortar specialist maxit (Azendorf) has developed a piece of completely new building material technology – the ecosphere insulation system. The Franconian company will first put this to use in interior wall insulation, followed by mortar-based façade insulation. Hollow glass microspheres act here as a lightweight aggregate and ensure top values in terms of thermal insulation, weight reduction and long-term stability. But what is so special about the revolutionary ecosphere technology? The mineral material can be sprayed from the building material silo and is therefore not only completely smooth but also easy to apply. The mineral spray insulation ecosphere will be presented to experts for the first time at BAU 2019 in Munich.
