Abstract:
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.
Abstract:
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.

Abstract:
This invention relates generally to a pre-finished, moisture resistant and durable building material that is able to diffuse stress caused by variations in temperature and climate. One preferred embodiment of the building material includes a fiber cement substrate, at least one resin impregnated paper, and a stress-relieving elastomeric film between the fiber cement substrate and the resin impregnated paper, wherein the elastomeric film acts as a stress relaxer between the fiber cement substrate and the one resin impregnated paper.
Abstract:
A coated substrate is configured with one or more cross-linked interfacial zones provided to improve the adhesion between the coating and substrate of the article or between adjacent coating layers. The coating composition contains molecules having at least two reactive functional groups capable of reacting with cross-linking molecules in the substrate and/or molecules in adjacent coating layers. The cross-linked interfacial zones improve the adhesion between coatings and the substrate and between adjacent coating layers.
Abstract:
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.

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.
Abstract:
A pre-finished, moisture resistant and durable building material is provided. In one embodiment the building material includes a fiber cement substrate having a first side and a second side, at least one resin impregnated paper over at least one of the first and second sides, and a stress-relieving polymeric film between the fiber cement substrate and the at least one resin impregnated paper, the polymer film acting as a stress relaxer between the fiber cement substrate and the at least one resin impregnated paper. In another embodiment, a stress-relieving polymeric coating or film is provided between resin penetrated sheets and a substrate. In another embodiment, a process for bonding the resin penetrated sheets to the substrate is provided.
