The present disclosure provides a heat-shielding panel having a heat-shielding function and a heat-isolating function, and a prefabricated building constructed by arranging a plurality of heat-shielding panels adjacently. The heat-shielding panel (1) of the present disclosure includes a pair of sheets (10, 20) and an enclosed space (30). The pair of sheets (10, 20) are provided with an exposed surface respectively, and back faces of the pair of sheets (10, 20) are oppositely arranged at intervals. The pair of sheets (10, 20) are formed by heat-shielding sheets (12). The enclosed space is arranged between the pair of sheets (10, 20). The enclosed space is formed by sandwiching a spacer (31) between the pair of sheets (10, 20). A fluid such as air is enclosed in the enclosed space.

Floor and ceiling panels and methods of constructing a floor system for a building are described. In some embodiments, a panel includes a plurality of joists, a corrugated form deck disposed above and attached to the plurality of joists, a ceiling substrate disposed below and attached to the plurality of joists, and an in-floor radiant heat member disposed between the corrugated form deck and the ceiling substrate. In some embodiments, the panel includes a plurality of joists, a corrugated form deck disposed above and attached to the plurality of joists, and a sound dampener disposed between the corrugated form deck and the plurality of joists. In some embodiments, the method includes attaching a pre-assembled panel to a frame of the building and pouring concrete onto the panel so that a radiant heat member is separated from the concrete by a corrugated form deck of the panel.

An insulating element for thermally insulating spaces, including closed cells, in which a first and a second group of closed cells are formed by first or second recesses in a first or second flat element and the first and the second flat elements form first or second connection regions between recesses adjacent to the edges of the openings, to which respectively a flat covering element closing the openings of a plurality of first recesses is bonded on a front side of the flat element. The second recesses are arranged between the first recesses on a rear side of the first flat element and the first recesses are arranged between the second recesses on a rear side of the second flat element such that the space remaining of the first and second recesses between the first and the second flat elements amounts to less than 50% of the space enclosed by the first and second recesses.

Provided is a shield in which a flexible member is interposed between two metal plates; still unfilled spaces that are not filled with the flexible member are secured, so that the shielding properties are improved by air layers. The shield 1A includes two metal plates 2, 3 disposed to face each other, and a plate-shaped flexible member 4 interposed between the two metal plates. Each of the two metal plates 2, 3 has a plurality of protrusion-depression structures. Gap-forming means is provided to form gaps of a width greater than the thickness of the flexible member 4 between the two metal plates 2, 3 when the flexible member 4 is interposed therebetween. Unfilled spaces (5) that are not filled with the flexible member 4 are provided between the two metal plates 2, 3.

In one example, the present invention is directed at a panel that includes (a) a first material having an inside surface and an outside surface, (b) a second material having an inside surface and an outside surface, (c) a zig-zag web with arms and apices disposed between the first material and the second material, (d) insulation disposed between adjacent arms, (e) a composite material comprising an adhesive and particulate material, wherein the composite material is applied to (i) inside surfaces of the first material and the second material, (ii) the zig-zag web, and (iii) the insulation; and wherein the outside surfaces of the first material and the second material are each substantially planar and parallel to one another, the inside surfaces of the first material and the second material contact the apices, and the first material and the second material are the same or different.

A plastic chamber insulator is provided. The plastic chamber insulator includes at least two horizontally parallel plastic sheets, wherein edges of the at least two plastic sheets are sealed to form a chamber. The interior of the chamber is filled, for example, with CO.sub.2 gas or air. The resultant product can be used for numerous insulation purposes.

Floor and ceiling panels and methods of constructing a floor system for a building are described. In some embodiments, a panel includes a plurality of joists, a corrugated form deck disposed above and attached to the plurality of joists, a ceiling substrate disposed below and attached to the plurality of joists, and an in-floor radiant heat member disposed between the corrugated form deck and the ceiling substrate. In some embodiments, the panel includes a plurality of joists, a corrugated form deck disposed above and attached to the plurality of joists, and a sound dampener disposed between the corrugated form deck and the plurality of joists. In some embodiments, the method includes attaching a pre-assembled panel to a frame of the building and pouring concrete onto the panel so that a radiant heat member is separated from the concrete by a corrugated form deck of the panel.

In an insulating element (1) for bounding spaces to be thermally insulated, e.g. for transport or packaging containers, comprising an in particular plate-shaped substrate element (2) made of a material having a low thermal conductivity, such as a polymer, the substrate element (2) is provided with a metallic coating (3) having a low emissivity in order to reduce the thermal radiation, yet is applied in a layer thickness of <80 nm, preferably <50 nm, such that the thermal conduction of the metallic coating will only insignificantly reduce the thus optimized insulating value. The metallic coating in the nanometer range does not only reduce the thermal radiation, but also enables optimal gas tightness with minimal thermal conduction.
