Wandsysteme aus Leichtbeton-Mauerwerk und mineralischem Putz

Properties of wall systems made of lightweight concrete masonry and mineral plaster.

The Decree for Saving Energy (Energieeinsparverordnung, EnEV 2009) consists stronger regulations for the yearly demand of energy and the loss of transmission heat of buildings. Therefore the average U-Value for enclosure walls decreases to 0.28 W/(m²K). Blocks made of aggregate lightweight concrete have been improved by the industry concerning their thermal conductivity in the last years, so these demands can be fulfilled with masonry 36,5 cm in thickness. Normally exterior and interior walls get a special plaster. Masonry, exterior and interior plaster form a system, which has to fulfill many physical aspects according to the building. Minerally exterior plasters with hydrophilic properties and interior plasters based on lime complete masonry made of lightweight concrete blocks in a perfect way.
