A convertible floor panel assembly incorporates a metal wire mesh subfloor and a polymer deck overlying the wire mesh subfloor. A plurality of alignment heads project from an underside of the polymer deck, and are designed to extend through respective mesh openings defined by the wire mesh subfloor. A plurality of panel retainers engage respective alignment heads, and are adapted for removably attaching the wire mesh subfloor and the polymer deck together. The floor panel assembly is thereby convertible between a substantially open-surface sound permeable safety structure and a continuous solid-surface structure for increased floor load capacity.

A roof cover board made from a mixture of 30-60% stucco; 20-50% perlite; 10-30% cellulose fiber; 3-20% starch; and siloxane. Also disclosed is a stucco-free roof cover board made from a mixture of 30-60% perlite, 30-60% cellulose fiber, 5-25% starch; and siloxane. Also disclosed are methods for making same.

Embodiments of the invention provide roofing boards and roofing systems having improved fire resistance properties and methods related to the same. According to one aspect, a roofing system is provided. The roofing system includes roofing panels positioned atop structural support members to form a roof deck. Roofing boards are positioned atop the roof deck and coupled thereto and a roofing membrane is positioned atop the roofing boards and coupled therewith. The roofing boards include a coating of a mineral based material applied to one or more surfaces in an amount between the range of about 0.10 lbs/ft.sup.2 and about 0.70 lbs/ft.sup.2. The mineral based material coating enables the roofing boards to pass the UL 790 class A tests, such as the burning brand test.

The present invention relates to a panel, in particular a wall, ceiling or floor panel, comprising a carrier layer made of a plastic material and a priming coat, wherein the priming coat comprises thereon an imprinted decorative pattern. Furthermore, the present invention relates to a method for manufacturing such a panel and a usage of a specific primer in such a panel.

A building panel is provided. The building panel includes an exterior wall portion, an interior wall portion, a pair of opposing sidewalls, a first end portion and an opposite second end portion. The pair of opposing sidewalls spacing apart the interior wall portion from the exterior wall portion to define a cavity therebetween. The exterior wall portion, the interior wall portion and the pair of opposing sidewalls are arcuate in shape to define the building panel. The first end portion has a slip lock slot extending between the pair of opposing sidewalls. The second end portion has a slip lock tab member extending between the pair of opposing sidewalls. The slip lock slot of the building panel is configured to receive the slip lock tab member of a second building panel to adjoin the first and second building panels in a continuous fashion.

Insulating panel (10) having a top face (12) and a bottom face (14) opposite the top face, comprising a body (20) made of stone wool with a part of substantially uniform first density and a part of substantially uniform second density, different from the first density, at least one profiled groove (22) being formed in said insulating panel starting from the top face, the top face (12) being made of stone wool, the groove (22) being formed in the stone wool, the number of grooves being less than or equal to three for 60 cm of a dimension of said panel perpendicular to the direction of the grooves.

A method for decreasing the vapour permeability of a water and air barrier treated substrate that includes treating the substrate with a liquid applied, vapour permeable air and water barrier coating composition comprising a cross-linked polysiloxane dispersion composition.

A wood or engineered wood structural panel, such as, but not limited to, OSB (oriented strand board) or plywood, that is both fire-resistant and water resistant. The panel is factory-coated with a product that provides fire resistance. The treatment gives it a Fire-Resistant (FR) performance (for use in a one- or two-hour rated assembly). The panel also is overlaid or coated in a factory setting with a weather/water resistive barrier (WRB). The structural panel thus combines a fire-resistant structural sheathing and WRB product in one integrated panel produced at a factory prior for installation at a job site.

The invention pertains to the field of construction of buildings and structures. The invention relates to alignment guides for constructing building components, namely walls, ceilings and floors to be used in buildings and structures. This invention also relates to kits of specific alignment guides and methods of using alignment guides.

The method for design of a seismic-damping partition wall with variable-friction-force energy dissipation provided by the present application includes the following steps: building a bare frame model without considering lateral resisting stiffness of a partition wall, and calculating an inter-story shear force and an inter-story displacement of a structure under action of an earthquake; calculating an elastic strain energy of the structure, and determining an expected additional damping ratio provided by a seismic-damping partition wall for the structure; determining a friction damping force-sliding displacement curve of a single group of seismic-damping partition wall panels, and establishing a relational expression between a total friction hysteretic energy and a friction damping force and a target sliding displacement of the single group of seismic-damping partition wall panels, and the seismic resilience of the partition wall and the structure can be synergistically improved.
