  • Structural fiber cement building materials
    Patent number: 8209927
    Abstract: A structural fiber cement sheet containing cementitious matrix and reinforcing cellulose fibers distributed throughout the matrix having a dry density less than 1.25 g/cm3, a thickness less than 0.7500 in, and able to withstand uniform loads of 200 psf or greater according to test method of Section 6.4.2.4 of PS2 and with a deflection of less than 0.067 inches at 60 psf when spaced on a span of 24 inches or less on center.
    Type: Grant
    Filed: December 20, 2007
    Date of Patent: July 3, 2012
    Assignee: James Hardie Technology Limited

  • Building material and method of making and installing the same
    Publication number: 20090320400
    Abstract: The building material, in one embodiment, has a jointing system that is uniquely configured to cover the frame of a structure. This building material, in one embodiment, is a building board with a conforming flange that is embossed onto the board and adapted to engage or mate with an end of an adjacent board. In another embodiment, the building material is an engineered panel joint comprised of a building board and a flexible or hinged article attached to the back surface of the building board. The article is preferably attached to the building board by an adhesive and extends beyond the edge and away from the building board for receiving a fastener to fix the building board to the structure. The fastener is preferably a nail. Components of the building material are preferably attached to the frame of the structure through the use of a single row of nails while maintaining or enhancing the shear strength performance of the building board system.
