An improved lath is disclosed having a water drainage layer provided in association with the lath. The water drainage layer serves to remove water that might otherwise build up between the lath and wall structure.

Gypsum panels, sheathing systems, and methods of making and using the same are provided. A gypsum panel includes a gypsum core associated with a first fiberglass mat having a continuous barrier coating, the coating penetrating a portion of the first fiberglass mat opposite the gypsum core, wherein gypsum penetrates a remaining fibrous portion of the first fiberglass mat such that voids in the first fiberglass mat are substantially eliminated. A building sheathing system includes at least two gypsum panels and a seaming component to provide a seam at an interface between the gypsum panels.

The present disclosure relates to a resilient and multipurpose window well installation. The installation comprises numerous different features and optional additional attachments and functionalities. In one embodiment, the installation can increase the amount of light entering into a basement window. In an alternative embodiment, the installation can also protect from influx of flood water through the basement window.

The present invention relates generally to an improved below grade, blind side, dual waterproofing membrane assembly incorporating a sheet membrane with adhesive to fully bond to concrete/shotcrete, and a method of making and using same. More particularly, the invention encompasses a dual membrane system that acts as a barrier, and prevents, and blocks water and moisture, from passing from one side of the structure to the other side. The innovative barrier layer system can be used along a wall, a floor, a ceiling, or along any structure which requires water or moisture proofing. The invention can be most effectively used between a concrete or shotcrete layer and the surrounding earth, such as, along an area that has a high water table or ground moisture or hydrostatic pressure that may creep into a foundation or a wall. The inventive system comprises two different waterproofing layers, and materials.

The invention relates to a vapor retarder membrane, intended to be used for improving the airtightness of a building or of a room, comprising at least one active layer having a water vapor permeability which increases with the surrounding relative humidity, said active layer comprising at least 90% by weight of a blend of ethylene/vinyl alcohol (EVOH) copolymer and of a copolyamide 6-6.6 (PA666), the latter having a melting point below 210° C.

A reinforced water-resistant board includes a cover board with a reinforced water-resistant membrane applied to a surface of the cover board. The reinforced water-resistant membrane includes a primer layer, a reinforced membrane, a traffic coat, and a sealing layer. The primer layer is applied over the surface of the cover board. The reinforced membrane includes fleece soaked in a liquid resin and is applied over the primer layer. The traffic coat is boned to the reinforced member. The sealing layer is applied over the traffic coat.

A prefabricated flashing product for an opening in an exterior surface of a structure includes a generally planar flange shaped to conform to the exterior surface, the flange extending outwardly from an entire perimeter of an aperture therein that corresponds to the opening, and a return that seals to the flange about the aperture and extends substantially perpendicularly therefrom toward an inward direction of the opening. The flange and the return are monolithically formed of a waterproof material. A method of integrating a fenestration product into an opening of an exterior surface of a structure includes inserting the flashing product described above into the opening, and inserting the fenestration product at least partially into the aperture of the flashing product.

Gypsum panels, sheathing systems, and methods of making and using the same are provided. A gypsum panel includes a gypsum core associated with a first fiberglass mat having a continuous barrier coating, the coating penetrating a portion of the first fiberglass mat opposite the gypsum core, wherein gypsum penetrates a remaining fibrous portion of the first fiberglass mat such that voids in the first fiberglass mat are substantially eliminated. A building sheathing system includes at least two gypsum panels and a seaming component to provide a seam at an interface between the gypsum panels.

The present disclosure relates to a precast load bearing roof deck element for a building comprising an upper floor layer of concrete, a load bearing steel reinforced lower layer of concrete, at least one thermally insulating layer located between and separating the upper floor layer of concrete and the lower layer of concrete, and a plurality of binders extending between the lower layer of concrete and the upper floor layer of concrete, the roof deck element configured to be mounted on a load bearing construction of the building. The disclosure also relates to a roof construction comprising a load bearing construction, such as a column and beam construction, and at least two of the above mentioned precast load bearing roof deck elements, wherein the roof deck elements are positioned side by side forming a gap between the roof deck elements, wherein the distance between the roof elements is between 0 mm and 100 mm, or between 1 mm and 100 mm. Furthermore the present disclosure relates to a method for manufacturing a load bearing roof deck element and a method for installing a roof construction on a load bearing construction of a building.

The invention includes a microbe-mitigating architectural barrier that includes a barrier forming material, and at least one biocide. The barrier forming material may be a bitumen product, an elastomeric polymer and combinations thereof. The microbe-mitigating architectural barrier may be formed by applying an emulsion composition directly to an architectural surface, or may be pre-formed and adhered or otherwise secured to the architectural surface in the form of a sheet or film. The invention also includes architectural assemblies and/or building envelopes that include the microbe-mitigating barrier. Related methods encompassed within the invention include a method of preparing an architectural barrier that includes: (a) preparing an emulsion that comprises a barrier forming material chosen from a bitumen product, an elastomeric polymer and combinations thereof, and at least one biocide, (b) applying the emulsion to at least one architectural surface, and (c) drying and/and or curing the emulsion to form a barrier.
