COMPOSITE BOARD

摘要

A composite board for use as backerboard for tile, the board including a mes h layer with a mesh fabric, a mat layer with a mat fabric and a polystyrene layer disposed between the two portions where a non-shrinking cement saturat es and connects the two outer portions with the polystyrene substrate. The composite board's mesh layer incorporates a stretchable mesh which in conjunction with the polystyrene substrate and the non-shrinking cement supports standard fasteners used in the home-building industry along with providing a suitable tile adhesion surface. The mat layer incorporates a fiberglass mat which provides high rigidity as well as being suitable for contact with an inner wall or studs. The combination of materials provides a backerboard that is light weight, rigid, economical and easy to build with.< /SDOAB>
