A paper based overlay is provided. The overlay has a paper impregnated with a resin composition having an acrylic resin having a glass transition temperature in a range of from about −20° C. to about 40° C. and a resin content from about 15 to about 35 wt. % based on the weight of the overlay. The acrylic composition may include wax in the amount of about 0.005 to about 3.5 wt. % based on the weight of the resin composition. A method of producing the overlay is also provided. The overlay is highly water and abrasion resistant with low volatile content.

Disclosed is a structural sheathing panel with an integrated drainage mechanism, comprising: a structural panel core; a plurality of rows, each row of the plurality of rows comprising raised elements deposited on an external surface of the panel and spaced from one another, each of the raised elements having an elongated, linear profile which has a longitudinal axis, wherein the longitudinal axis of at least one of the raised elements of each row is not parallel to any edge of the panel.

Gypsum panels and methods for their manufacture are provided herein. The gypsum panels include a gypsum core having a first surface and a second opposed surface and a first fiberglass mat associated with the first surface of the gypsum core, such that gypsum from the gypsum core penetrates at least a portion of the first fiberglass mat.

A method for construction using a panel and plank system that may optionally be made of Aerated Autoclaved Concrete (AAC), wherein wall panels are delivered, erected and attached to structural forms and braced with properly designed shoring/struts with form ties and specifically designed “panel ties”. Intermediate bracing is installed at midspan locations where spans are short and there is a possibility of wall buckling. Floor/roof planks are set on top of the walls being cognizant of bearing surface requirements. The deformed and post-tension reinforcing steel is set/installed and any miscellaneous detailing is completed. Thin AAC panels can be installed as form liners for added insulation where dimensions accommodate them. Structural grout or small aggregate concrete is placed, consolidated/vibrated, and finished and allowed to cure to minimum required strengths. Roof pours are given a “crown” to allow proper drainage.

Described herein is a drywall apparatus and method. The apparatus includes a finishing drywall liner, a framing drywall liner, a first gypsum-containing segment between the finishing drywall liner and the framing drywall liner, and a second gypsum-containing segment between the finishing drywall liner and the framing drywall liner. The first segment and the second segment are connected by a hinge formed from the finishing drywall liner and the framing drywall liner to allow an angle between the first segment and the second segment to vary.

An exterior sheathing cementitious panel which prevents water penetration and air leakage is provided. Methods for manufacturing exterior sheathing cementitious panels with a highly efficient integrated air/water barrier sheet are also provided. An exterior sheathing system employing the exterior sheathing cementitious panel is provided.

A plasterboard comprising a gypsum matrix having wood particles embedded therein in an amount of at least 2 wt % relative to the gypsum, the gypsum matrix further comprising glass fibres in an amount of at least 1 wt % relative to the gypsum.

[Object] To provide a building material having excellent durability. [Solution] A building material has a convex part formed on a surface thereof, the convex part including a first lateral surface part and a second lateral surface part corresponding to the first lateral surface part. The building material is formed from a mixture containing a hydraulic material, an admixture, and a plant-based reinforcing material, and the plant-based reinforcing material at least in the convex part is distributed in the mixture with the hydraulic material and the admixture attached to the plant-based reinforcing material. A distribution of the plant-based reinforcing material in the first lateral surface part and a distribution of the plant-based reinforcing material in the second lateral surface part are substantially the same. Desirably, the convex part includes a first edge part that is an edge part of the first lateral surface part and a second edge part that is an edge part of the second lateral surface part and that corresponds to the first edge part, and a distribution of holes formed in the first edge part and a distribution of holes formed in the second edge part are substantially the same.

A ballistic panel formed with a ballistic material, the panel comprising: a panel with a filled void; wherein the filled void is filled with a ballistic replacement material; and wherein the filled void exhibits ballistic properties equivalent to the ballistic panel formed with the ballistic material; wherein the ballistic replacement material and the ballistic material comprise between about 1121 kg/cubic meter (about 70 pounds per cubic foot) and about 1442 kg/cubic meter (about 90 pounds per cubic foot); and wherein the ballistic replacement material and the ballistic material comprise: about 1 part by mass Portland cement; about 0.5 to 1.5 part by mass fine aggregate; and about 0.0005 to 0.05 part by mass air entrainment additive; about 0.005 to 0.15 part by mass fiber; about 0.005 to 0.05 part by mass aluminum hydroxide and about 0.005 to 0.05 part by mass calcium phosphate.
