Energy-Efficient Retrofit of Buildings by Interior Insulation: Materials, Methods and Tools offers readers comprehensive coverage of current research in German Language Countries. Chapters provide an overview on the development of energy efficiency for building retrofits and the role of internal insulation, cover materials with chapters on Brick, Wood, Plaster, Clay, and Natural Stone, explain the impact of internal insulation in those materials and how to cope with problems such as moisture build, mold and algae growth, provide practical advice on how to apply internal insulation in the most effective way, including Salt Efflorescence, Noise Protection, Fire Prevention, and more.

The practical approach of the book, with examples in all chapters, makes it valuable for Civil and Architectural Engineers involved with building retrofit. The book may also be useful to researchers in the field of Building Physics due to the breadth of the coverage.
