Metfiber Eco Wall Sound

Metfiber Eco Wall Sound

Metfiber® Eco Wall Sound with an insulation core of glass wool is THE solution for buildings with high requirements on sound insulation and sound absorption. The design of the perforated internal sheet improves room acoustics substantially. This system (patented by Metecno) uses a special fleece material as a trickle protection between the internal sheet and the glass wool core. In addition to the outstanding acoustic properties, the glass wool used in this product consists of 80% recycled material, thus contributing significantly to the saving of natural resources and making the product an ecological building material. Generally used as ceiling or partition wall, Metfiber® Eco Wall Sound may also be used as external wall in specific cases, though it is generally not recommended to apply this panel in heated buildings or buildings with high moisture. For additional information, please have a look at our detailed technical manual.
