Patent number: 8906500Abstract: 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: GrantFiled: March 7, 2013Date of Patent: December 9, 2014Assignee: James Hardie Technology LimitedInventors: Weiling Peng, Hong Chen, Caidian Luo, Donald J.

Patent number: 8409380Abstract: 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: July 28, 2009Date of Patent: April 2, 2013Assignee: James Hardie Technology LimitedInventors: Andrew J.

Patent number: 8297018Abstract: Protected prefinished fiber cement products are manufactured by applying a protective layer on the finished surface of a fiber cement product. The protective layer protects the finish layer of the prefinished fiber cement product during handling, storage, and transport. Removing the protective layer leaves no adhesive residue on the finish layer, does not damage the finish layer, and does not substantially tear the protective layer. Protected prefinished fiber cement products are typically stacked on pallets for storage and transport. Optionally, spacers may be placed between the stacked protected prefinished fiber cement products.Type: GrantFiled: July 16, 2003Date of Patent: October 30, 2012Assignee: James Hardie Technology LimitedInventor: Weiling Peng
