Description

Kassetteneinlage is an acoustic infill made of Basotect FM, a melamine resin foam with a mineral impregnation, for backing perforated or slotted ceiling linings of metal, gypsum, plastic or wood. Besides the uncoated version, a colour-coated version is available for applications with higher visual demands. It is used in new installations as well as in refurbishment.
