REAPOR® - Sintered open-pore glass foam as a high-strength sound absorber

Abstract

The market for sound insulation products and Services, accounting for some 6000 mill. DM per annum in Germany alone, is covered to the extent of more than 90% by developments which are over 40 years old. Experts at the Fraunhofer Insdtute for Building Physics (IBP) (Director: Prof Dr. Dr. h. c. mult. Dr. E. h. mult. K. Gertis) have, together with an increasing number of small to medium-sized licensees, concentrated on the development of alternative, fibre-free absorbers (ALFA). The aim is to thus reduce noise pollution with more efficient sound-proofing technologies even in cases where traditional sound insulation materials are at a disadvantage as regards fitting and durabihty.
