ABSTRACT:
The present invention relates to laminated acoustical tile products which are derived from compositions that are suitable to provide rigid, water-resistant phosphate ceramic materials. The tile products comprise a decorative facing comprising a substantially open-celled character and a backing layer of higher density, the backing layer and edges of the tile comprising substantially closed-celled facing characteristics. The backing layer provides structural strength and dimensional stability to the tile product whereas the decorative, open-celled facing provides access by sound waves to the interior regions of the board. The resulting composite material provides good acoustical performance, yet is capable of withstanding conventional handling stresses.
