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.

Abstract: A heat exchanger panel for a surface of a room, the panel having plate-type heat exchanger elements and having a heat exchanger pipe. The heat exchanger elements include two main surfaces facing away from each other and a peripheral surface linking the main surfaces, a fiber mat and a thin plaster layer. The plaster layer adheres to the fiber mat and the heat exchanger pipe extends at least partially within the plaster layer. The pipe has at least two connections in the area of the peripheral surface.

Abstract: The invention relates to a heat exchanger paneling surface of a room, which comprises plate-type heat exchanger elements (8) having at least one heat exchanger pipe (2). Said elements comprise two main surfaces (7) facing away from each other and a peripheral surface (6) linking the main surfaces, a fiber mat (1) and a thin plaster layer (3). Said plaster layer (3) adheres to the fiber mat (1) and the at least one heat exchanger pipe (2) extends at least partially within the plaster layer (3). The pipe (2) has at least two connections (2a) in the area of the peripheral surface (6). The fiber mat (1) has an insulating effect. The thin plaster layer and the fiber mat guarantee that the major portion of the heat flow to and from the at least one heat exchanger pipe (2) takes place through the plaster layer (3), i.e. directly between the interior and the pipe (2).

Abstract: In order to reduce the heat transfer coefficient of coated building panels, the coating and the building panel have a high voidage. This high voidage can be obtained by using a fiber mat and a porous coating applied to the fiber mat. The porous coating includes porous glass particles and a low amount of a binder. The porous glass particles are held together by binder bridges, including a silicate binder and a low amount of an organic dispersion binder, for example an polymeric styrol acrylate. The partial volume filled by the binder bridges is small and therefore there is a remarkable first empty partial volume in between the porous particles. A second empty partial volume is located within the glass particles. The total volume of all pores of the glass particles is a relevant part of the total coating volume. This second empty partial volume is a very good thermal isolation because the individual pores are small and to a high percentage closed chambers not connected to the ambient.
