An acoustic isolation booth for providing a space for noisemaking out of earshot from other parties. wherein: the acoustic isolation booth comprises a shell comprising at least two compartments, an intermediate wall, a plurality of outer walls, a ceiling and one or more entryways. The shell comprises a shell width, a shell depth and a shell height. The two compartments comprise at least a first compartment and a second compartment. each of the two compartments comprises a compartment depth, a compartment width and a compartment height. A first side wall, the intermediate wall and a second side wall are configured to divide a space within the shell into the first compartment and the second compartment.

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.

The prefabricated floor panel can include at least two planar panel members being spaced apart by and sandwiching a core, the core having at least one undulated inner support extending along a longitudinal axis and having summit portions, valley portions, and intermediate portions each extending between corresponding summit and valley portions, each of the summit, valley, and intermediate portions having opposed side edges, a span of the at least one inner support being defined between the opposed side edges, each side edge abutting against a corresponding one of the panel members, the undulated inner support having at least one sheet of wood material, fibres of said sheet of wood material being oriented normal to the panel members and parallel to the span, the at least one undulated inner support being laterally sandwiched between inner ribs with the summits being disposed adjacent a first one of the inner ribs and the valleys being disposed adjacent a second, opposite one of the inner ribs, the inner ribs being planar and having a span being defined between opposed side edges, each side edge of the inner ribs abutting against a corresponding one of the panel members.

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.

A floor panel is arranged for forming a floor covering, and substantially consists of synthetic material and has a decorative upper side. The floor panel, on at least one pair of opposite edges, comprises coupling parts which allow coupling two of such floor panels to each other. The coupling parts effect a locking in a first direction perpendicular to the plane of the floor panels as well as in a second direction perpendicular to the respective edge and in the plane of the floor panels. The at least one of the coupling parts comprises a separate locking element, which, in coupled condition, provides for at least a locking in the first direction.

A set of essentially identical floorboards each including a front face and a rear face extending in the horizontal plane, a core, and a surface layer, a mechanical locking system is arranged at least at two opposite edges for connecting a floorboard with an adjacent floorboard in a horizontal and a vertical direction, said mechanical locking system being configured for connecting the floorboard with the adjacent floorboard by vertical folding, wherein one of said opposite edges is provided with a horizontally extending protrusion at an upper edge, and wherein said protrusion is configured to overlap a surface groove at an upper edge of the other of said opposite edges, such that two connected and adjacent floorboards have upper overlapping edges.
