Title:
IMPROVED FIBERGLASS MESH SCRIM REINFORCED CEMENTITIOUS BOARD SYSTEM
Document Type and Number:
WIPO Patent Application WO/2012/078366
Kind Code:
A3
Abstract:
A cementitious board system which is reinforced on its opposed surfaces by an improved glass fiber mesh scrim with thicker yarn and larger mesh openings to provide a cementitious board with improved handling properties while retaining tensile strength and long term durability. The fabric is constructed as a mesh of high modulus strands of bundled glass fibers encapsulated by alkali and water resistant material, e.g. a thermoplastic material. The composite fabric also has suitable physical characteristics for embedment within the cement matrix of the panels or boards closely adjacent the opposed faces thereof. The fabric provides a board system with long- lasting, high strength tensile reinforcement and improved handling properties regardless of their spatial orientation during handling. Also included are methods for making the reinforced board.
