A structural reinforcement for an article including a carrier (10) that includes: (i) a mass of polymeric material (12) having an outer surface; and (ii) at least one fibrous composite insert (14) or overlay (960) having an outer surface and including at least one elongated fiber arrangement (e.g., having a plurality of ordered fibers). The fibrous insert (14) or overlay (960) is envisioned to adjoin the mass of the polymeric material in a predetermined location for carrying a predetermined load that is subjected upon the predetermined location (thereby effectively providing localized reinforcement to that predetermined location). The fibrous insert (14) or overlay (960) and the mass of polymeric material (12) are of compatible materials, structures or both, for allowing the fibrous insert or overlay to be at least partially joined to the mass of the polymeric material. Disposed upon at least a portion of the carrier (10) may be a mass of activatable material (126). The fibrous insert (14) or overlay (960) may include a polymeric matrix.

A floor, wall or ceiling panel comprises a core and a decorative top layer provided on the core. The core comprises a magnesium oxide-based board material, and wherein the aforementioned panel, on at least two opposite edges, is provided with coupling means allowing that two of such panels can be interlocked at the respective edges.

A panel includes two or more units connected to each other. At least one of the units is a bonding unit that provides adhesion between itself and at least one other of the units. The adhesion is decreasable by a debonding activator. An adhesive system for panels is provided along with use of the adhesive system and a method for disassembling a panel.

A building board, particularly a gypsum board, can include a first cover sheet, a second cover sheet, and a core disposed between the first and second cover sheets. The core can include gypsum, microsilica, and an additive. The microsilica can no greater than 2.7 wt. % of the building board. The additive can include a polysiloxane material and be no greater than 0.25 wt. % of the building board.

Glazings including first and second channel-section glazing elements arranged to define a cavity in which an inner glazing element is located are described. An end of a first flange of the first channel-section glazing element is spaced apart from a web of the second channel-section glazing element by a first space. The inner glazing element includes a central portion, a first edge portion running along a first side of the central portion, and a second edge portion running along a second opposite side of the central portion. A first portion of the first edge portion is positioned in the first space and is compressed by the end of the first flange of the first channel-section glazing element being positioned relative to the web of the second channel-section glazing element to form the first space.
