A flashing for concrete board siding includes a substantially rigid panel, a guide protrusion, an interior protrusion and at least one strip of adhesive double-sided tape. The guide protrusion and interior protrusion are integrally formed with the panel at opposing ends. The at least one strip of adhesive double-sided tape is on an exterior face of the panel. In an embodiment, a channel separates two or more strips. Some embodiments include at least one groove disposed between two or more strips. Further, a method of installing concrete board siding to a structure includes fastening a first piece of cement board siding to the structure, providing an embodiment of the flashing disclosed herein, positioning the interior protrusion on the top edge, adhering a second piece of cement board siding to the least one strip of adhesive double-sided tape and fastening the second piece of cement board siding to the structure.

A first building panel (110) and at least a second building panel (120) fixed to a building substructure (300) in a predetermined arrangement thereby forming a joint profile (150). Each of the first and at least second building panel comprise a first profiled side edge (140) and a second profiled side edge (145) which are of complementary configuration such that the first profiled side edge of the first building panel is configured to engage with the second profiled side edge of the at least second building panel. The first and second profiled side edge being further configured to form an engineered adhesive reservoir (155) therebetween when the first profiled side edge and second profiled side edge are engaged together. The joint profile further comprising a structural adhesive (285) at least substantially filling the engineered adhesive reservoir.

A joiner clip for securing panels to a substrate is provided that includes a sheet of material that has a first portion, a second portion, a first face, and a second face. On the first face, a first anchoring cleat is located in the first portion and a second anchoring cleat is located in the second portion. A spaced guide is positioned between the first portion and the second portion of the sheet on the first face. A mounting hole is formed through the sheet and is positioned colinear with the spacer guide. A fastener from the second face secures the joiner clip and panels to a vertical stud substrate. A construction unit including the joiner clip for securing panels of material to a vertical stud substrate is also provided. A butt joint is readily formed between two secured panels.

A cladding element, for use in a building envelope, comprising a first face, a second face and a plurality of edges. One or more of the plurality of edges includes a mating feature configured to resist moisture passage between cladding elements when the cladding elements are installed on a wall or other structure. The mating features of each cladding element including one or more beveled edges designed to improve mating between the cladding elements and the overall aesthetic appearance of the mating interface between adjacent cladding elements when installed on a wall or other structure.

Disclosed herein is a fiber cement cladding system such as fiber cement shingles or shakes which can have the appearance of authentic wood. Each individual fiber cement shingle or shake comprises a textured surface having a depth of relief and a coating system disposed on the textured surface. The coating system may include a sealing agent, a basecoat, and a topcoat. In some embodiments, the basecoat is disposed on at least a portion of the sealing agent and the topcoat is disposed on at least a portion of the basecoat. In some embodiments, the basecoat comprises a DFT of 1 to 3 mils and the topcoat comprises a DFT of 0.05 to 2 mils. In some embodiments, the depth of relief of the textured surface of the fiber cement shingle is about 0.045 to 0.085.

A plurality of ventilation elements, vents, slots, or gap elements or similar features that are applied to, or machined into, one or more sides of exterior siding products, such as lap siding, panel siding, decorative trim, or other cladding materials. When the exterior siding product is installed, the ventilation elements, vents, slots, or gap elements or similar features provide a built-in air and water gap to facilitate and increase water drainage and air circulation behind the siding or panel, thereby minimizing water storage in the space behind the siding and lowering the equilibrium moisture content of the siding itself. The ventilation features are incorporated into the corresponding product in-line or during the manufacturing process, and do not require any further work during assembly or construction on-site (e.g., furring strips or other similar drainage mechanisms are not needed). Some or all of the ventilation features or elements are located to improve the product's ability to equilibrate (moisture-wise) in a product stack before installation as well as after installation.

A flashing for concrete board siding includes a substantially rigid panel, a guide protrusion, an interior protrusion and at least one strip of adhesive double-sided tape. The guide protrusion and interior protrusion are integrally formed with the panel at opposing ends. The at least one strip of adhesive double-sided tape is on an exterior face of the panel.

Further, a method of installing concrete board siding to a structure includes fastening a first piece of cement board siding to the structure, providing an embodiment of the flashing disclosed herein, positioning the interior protrusion on the top edge, adhering a second piece of cement board siding to the least one strip of adhesive double-sided tape and fastening the second piece of cement board siding to the structure.

Described herein are cementitious articles having an integrally formed exterior surface with ultra-smooth finish and reduced porosity and/or thickness relative to the core of the cementitious article. Described herein are also techniques and methods for producing fiber cement articles having a thin exterior shell characterized by improved smoothness and reduced porosity.

A lap siding product with a unique shiplap joint that spaces abutting pieces of siding correctly from each other without installer measurements. The shiplap joint comprises a bottom element and a top element. A lap siding panel or board has a bottom element shiplap joint at one end, and a top elements shiplap joint at the other end. The corresponding ends of two lap siding panels or boards (i.e., one bottom element and one top element) together form the unique shiplap joint of the present invention. One or more drainage channels or grooves help re-direct water from the joint, and at least one of the channels or grooves also provides a visual element for proper spacing. An engineered stop on the underside of the top element also helps space the pieces of siding correctly, without requiring measurement during installation.
