A structural insulated panel, SIP, (101) for a building (100) in which the SIP is attachable to another such SIP (101) to provide a structure of the building (100). The SIP (101) comprises a frame (200), a first board (208) attached to a first face of the frame (200), a second board (209) attached to a second face of the frame (200) and an insulating layer (401) bounded by the frame (200) and the first (208) and second boards (209). The frame (200) is fibre-reinforced plastic, FRP. The frame (200) has a joining surface that faces away from the centroid of the SIP (101) so as to be mateable with a joining surface of a frame of another such SIP (101).

Enclosures are used to attenuate noise produced by a high decibel producing device, such as a gas turbine engine or other rotating machinery. However, enclosures that achieve high Sound Transmission Class (STC) ratings are generally expensive and immobile, whereas inexpensive and mobile enclosures are generally incapable of achieving high STC ratings. Accordingly, a composite noise-attenuating panel system is disclosed that can achieve the high STC ratings associated with immobile, site-erected enclosures, using subpanels that are separated by an air gap and an internal filler (e.g., mineral wool), while maintaining the weight, form factor, and ease of use associated with lightweight, modular mobile enclosures.

A system and method for forming an easily-erectable modular business cubicle is provided. The system/method involves the use of a rectangularly-shaped tile that has distinct connectors on each of its four sides. On one tile side is a single coupling connector and on the opposite is a multiple coupling connector. On the top is a connector comprising a plurality of elongated parallel grooves and on the bottom is a connector comprising a plurality of elongated parallel tongues corresponding to the top connector. These integrated connectors allow a plurality of these tiles to be releasably coupled to each other, both in a horizontal direction and a vertical direction. In addition, since no tools or separate connectors are required, a variety of cubicle styles can be easily formed and then later the cubicle can be dis-assembled or reconfigured into a new cubicle style. Tiles of different heights, but with the same connector configurations are also provided.

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).

A dry partition wall system comprising a plurality of wall elements, a floor-side connection element extending over several wall elements, a ceiling-side connection element extending over several wall elements, in which the plurality of wall elements are arranged side by side and are retained on the floor-side connection element and on the ceiling side-connection element and thus jointly form a partition wall, and in which the wall elements are of a multi-layer design.

Wall-building element system comprising sole elements, basic wall-building elements adapted to be assembled to a wall, and beams adapted to be fitted between each horizontal layer of the basic wall-building elements. The basic wall-building elements are prefabricated with a central, load bearing core member and form-stable layers of thermal insulation on both sides thereof. The core member and the thermal insulation layers are mutually adapted in a tongue-and-groove system while the beams are made in an “H”-profile corresponding thereto. The core member typically consists of a plate-shaped main body provided with laterally extending, vertically oriented ribs.

A modular device adapted for subdividing room space, the modular device comprising: a panel comprising a corrugated portion positioned between a first planar surface and a second planar surface of the panel, wherein the peaks of the corrugated portion are in engagement with the first planar surface, wherein the troughs of the corrugated portion are in engagement with the second planar surface; the first planar surface and the second planar surface each having a first end and a second end; wherein the first and second ends of the first planar surface are respectively opposite relatively to the first and second ends of the second planar surface; the second planar surface is parallel to the first planar surface; wherein the corrugations are is parallel to the vertical axis of the panel; a concave female portion positioned along the vertical axis in the panel, wherein the concave female portion is formed from at least: the first end of the first planar surface, the first end of the second planar surface, and a curved portion from the corrugated portion; a convex male portion positioned along the vertical axis of the panel, wherein the convex male portion is positioned outside of the second end of the first planar surface and the second end of the second planar surface; wherein to extend the length of the panel, the convex male portion of a first panel is adapted to engage with the concave female portion of a second panel.
