Described herein is a barrier coating composition comprising an organic blend comprising a first component and a second component, the first component comprising latex polymer and the second component being selected from polyurethane emulsion, wax emulsion, and alkyd emulsion, wherein the first component and the second component are present in a weight ratio ranging from about 2:1 to about 20:1, and the latex polymer has a glass transition temperature of less than about 18° C.

Prefabricated wall panels simplify the constructive of building units and other structures. The prefabricated wall panels can include a set of conduits pre-installed within the wall panels that enable simplified installation and conduit routing within a building unit or structure. The set of conduits can include electrical conduit, plumbing conduit, HVAC conduit, networking conduit, fire alarm conduit, and fire sprinkler conduit. The prefabricated wall panels can include above-door cavities to assist with structure design and coupling conduits between prefabricated panels. The prefabricated panels can additionally include dual-headed fire sprinklers that enable one fire sprinkler conduit to spray into multiple rooms, reducing the overall number of fire sprinkler conduits required within a structure.

The panel-modular layered wall system for shaping spatial structures is characterised by the fact that: the arrangement of horizontal layers configured by means of joined sideways panels of various shapes, filled with the substrate, whose surfaces are planted with plants according to the principle of bipolarity, preferably using transparent or opaque panels, which are mounted on cantilevers with a variable supporting angle, always forms the horizontal arrangement of panels, placed a maximum of three (when with plants and more when without) on the flat or bent frame of the module in the shape of a rhombus, a rectangle and a trapezium made of a closed profile with a rectangular cross-section, where the frames of modules joined together along the perimeter by means of couplers form the vertical load-bearing frame, sloping load-bearing frame, arched-barrel load-bearing frame, spherical load-bearing frame, cylindrical load-bearing frame and sloping cylindrical load-bearing frame, which, together with the use of silos filled with the substrate, joining individual panels and layers, forms self-supporting layered wall structures in six variants, which can be configured with each other.

A first unit (100) including a first member (110) of a releasable fastening arrangement (300) is presented. The releasable fastening arrangement (300) is arranged to provide a mechanical connection of the first unit (100) to a second unit (200), and an electrical connection of a first electrical circuit (120) included in the first unit (100) to a second electrical circuit (220) included in the second unit (200), when a male profile (115) of the first member (110) is inserted into a corresponding female profile (215) included in a second member (210) of the second unit (200). The mechanical connection is provided based one or more at least partially resilient latching arm members (117) of the male profile (115) engaging with one or more corresponding slots (217) of the corresponding female profile (215). The electrical connection is provided by contact between one or more first flexible conductors (124) arranged on a first flexible and electrically insulating layer (126) of the first electrical circuit (120) and one or more second flexible conductors (224) arranged on a second flexible and electrically insulating layer (226) of the second electrical circuit (220).

A ventilation panel for a soil gas barrier system includes: an insulating foam body having first and second opposing faces and a plurality of grooves to define, in cross-section, an interconnected plurality of ventilation channels having walls that extend into the ventilation panel from the second face toward the first face; and a film of substantially gas-impervious material attached to at least one of the first face and the second face.

An integrated roofing product comprising a wood or cellulosic structural or roof sheathing base or core panel with a rigid foam insulation sheet or layer laminated or otherwise attached to the panel's inner face. Shingles and/or other protective material may then be attached to the panel's outer face. A plurality of parallel air channels extend vertically in the rigid foam insulation sheet or layer, providing a pathway for air to pass up and out of the eave space. Some or all of the air channels are disposed on the surface of the foam layer that is laminated or attached to the panel's inner face, so that part of the air channel is formed at the interface. A radiant barrier layer may be placed on the inner face of the rigid foam insulation sheet or layer, or between the foam insulation and the inner face of the roof sheathing base or core panel.

Fire-retardant panels that include: a frame with multiple holes that reduce heat conduction through the panel; or a frame that includes two portions separated by a layer of fire-resistant material (e.g., gypsum, calcium silicate, or gypsum board). Some embodiments include skins (e.g., sheet metal) or insulation (e.g., between skin and fire-resistant material, for instance, within the frame). In particular embodiments, the fire-resistant material is (e.g., midway) between: two skins, two layers of insulation, two portions of the frame, or a combination thereof. The portions of the frame can be: sheet metal, attached (e.g., screwed) to the skin(s) or to each other, or extend around the perimeter. The frame can include: various elongated members, (e.g., parallel) bends, or holes that are: in at least one row, elongated, or slots (e.g., parallel to each other or to the skin).

The invention relates to a system for erecting a building structure, the system comprising a foundation for receiving the building structure, and a plurality of inner and outer walls, roof and floor panels, the panels being adapted to engage each other for defining at least one story of the building structure, wherein the foundation comprises a first section and a second section, the first section being adapted to bear the load of the building structure and the second section being adapted to provide access to the interiors of the building structure.

A modular, self-contained unit that includes utility input and output connections and connective pathways in communication with the input and output connections that provide an internal flowpath for utilities such as, but not limited to, chilled and heated domestic water, chilled water, processed chilled water, compressed air, various gaseous services, electricity, and digital data communications. The internal flowpaths may also comprise a service pathway in communication with an isolation component that allows control and use of the utility by an end user (or other end-user equipment, end-user systems, or end-use devices). The self-contained modular units may be directly or indirectly in communication with similar self-contained modular units, such that the utility services may flow through and into multiple units. The self-contained units may be moved manually, automatically, or electrically through various implements, and the self-contained units may be sized to allow easy entry into spaces through standard openings to the spaces.
