Patent number: 7713615Abstract: In one embodiment, a reinforced fiber cement article comprising a fiber cement piece and a reinforcing fixture bonded to a portion of the fiber cement piece for improving the performance, strength and durability of the fiber cement piece. The reinforcing fiber cement article could be used as or in conjunction with a siding plank assembly, which further comprises an interlocking feature that allows the siding plank to be stacked with other siding planks in a manner such that a uniform and deep shadow line is created. The interlocking feature sets the gauge of the exposed plank face and allows for leveling of the plank during installation. The reinforcing fixture could also serve as a thick butt piece or a plastic spline that produces a deep shadow line. A cementitious adhesive is used to bond the reinforcing fixture to the fiber cement piece.Type: GrantFiled: April 3, 2002Date of Patent: May 11, 2010Assignee: James Hardie International Finance B.V.Inventors: Andrew J.

Patent number: 7497153Abstract: The cutting tool shown generally as 1, has a disc with a peripheral cutting face. In this embodiment the cutting face includes an array of eight circumferentially spaced teeth 2. An open circumferential gutter 5 is located inboard of the teeth and is recessed into a lateral face of the disc. Fluid in the gutter drains into the passageways through the respective inlets under the apparent force due to rotation. A fluid passageway 9 runs between the gutter and the base of the each tooth. The fluid is thereby forced through the passageway and out of outlet 11.Type: GrantFiled: November 8, 2004Date of Patent: March 3, 2009Assignee: James Hardie International Finance B.V.Inventor: Greg Brunton

Publication number: 20080141908Abstract: An engineered composite building material, such as fiber cement, having one or more engineered sub-surface regions designed to provide the building material with improved moisture ingress resistance, paint adhesion, and other mechanical properties is provided. The sub-surface region has a cement-polymer matrix formed by introducing an impregnating agent into the pores of the substrate. The composite building material may be formed by applying impregnating agents to the subsurface regions of the substrate to form chemical and/or mechanical bonds with the matrix of the building material, the reinforcement fibers, and/or the surface coatings applied to the material. The thickness of the sub-surface regions may be controlled by varying the viscosity and porosity of the building material substrate. The cement-polymer building material has enhanced durability, weather resistance, strength, and stiffness.Type: ApplicationFiled: December 13, 2006Publication date: June 19, 2008Applicant: JAMES HARDIE INTERNATIONAL FINANCE B.V.Inventors: Weiling Peng, Hong Chen, Caidian Luo, Donald J.
