Abstract: A facade element for heat-insulation purposes has at least two parallel panels (101, 102), a cavity (103), which is formed between these two panels (101, 102) and has fluid flowing through it, and at least one inlet (13), for feeding a radiation-absorbing fluid, and at least one outlet (13?), for discharging the fluid. The inlet (13) is arranged on a first side of the panels (101, 102) and the outlet (13?) is arranged on an opposite, second side of the panels (101, 102). The at least one inlet (13) and the cavity (103) have arranged between them a first flow distributor (14), which extends for distribution along the length of the first side. This facade element makes straightforward and cost-effective industrial production possible.

Abstract: Disclosed are surface sections for creating a non-slip or minimal slippage surface. The surface section includes a plate, a plurality of plate apertures, at least one elevator, a plurality of pegs, and a plurality of couplers to couple the pegs to the plate. Each of the plurality of pegs is at least partially located within, and aligned with, one of the plate apertures. Each coupler couples one of the plurality of pegs to the plate in a normal, extended state in which at least a portion of the peg is extended above the upwardly facing surface of the plate. Each coupler allows each of the plurality of pegs to move within its respective plate aperture to a non-extended state upon application of pressure to the peg. When the pressure is removed, the coupler moves the peg back to its normal, extended state.

Abstract: A room enclosure assembly on a base of a concrete ceiling or wall is disclosed. In an embodiment, it includes metal sheet material having contact surfaces toward the base and web faces leading away from the base and heat exchange surfaces. Folding regions are formed between the sub-faces of the sheet material. The contact surfaces are fastened to the base area via a heat conducting connection layer. The heat-exchange faces are provided with a coating layer. The heat flow between the base and the heat exchange surfaces is especially efficient because it takes place in the continuous metal sheet material. Through-openings in the heat exchange surfaces, together with the use of a suitable coating layer on the heat exchange surfaces, allow for the acoustic insulating effect and optical appearance to be optimized.
