A bracket holds a rigid or flexible tube during the pouring of a concrete slab. The bracket has a base and a housing connected to the base. The tube curves around a first tube support on the housing before passing through an opening in the bottom of the housing. The tube and any members inside the tube are cut off so they end inside the housing and are then covered by a housing cap. The base is fastened to a form for the concrete slab. The height of the housing relative to the base is adjusted to place the cap at the planned surface of the concrete slab. After the concrete slab is formed the cap is removed and the cut members inside the housing are connected to other members or devices.

The invention relates to a device for supporting and fastening heating pipes of a heating system placed in subfloors, walls or ceilings of a building.

The device comprises: a laminar body having a first face and an opposite second face, a plurality of fastening elements made in one piece on the first face of the laminar body and configured to fasten said heating pipes on the first face. The invention is characterized in that both the laminar body and the fastening elements of the device are in a mixture comprising at least one thermoplastic polymer and thermally conductive inorganic fillers.

The disclosure relates to a covering system for a floor, a wall and/or a ceiling. The covering system includes a decorated side, a lower side opposite the decorated side and a plurality of interconnected covering elements. At least one conducting element is arranged between at least two of the covering elements in such a way that the at least one conducting element is at least partially visible on the decorated side. The at least one conducting element is configured to conduct a physical quantity, material or signals. The at least one conducting element includes an interface to a source or a consumer of the physical quantity, material or signals.

Using thermal radiation to supply occupant comfort has long existed in the heating domain, and to a lesser scale in the cooling domain. Cooling power of radiant cooling systems is limited by the risk of condensation on the panel itself, as well as adjacent surfaces. Similarly, convective system losses to the ambient air prevent maintaining a large temperature difference from the surface and the surroundings. The disclosed approach combats these common pitfalls of radiant cooling systems in the building domain, increasing the power and therefore applicability of radiant cooling.

A curtain wall includes one or more mullion profiles and one or more transom profiles and panels which are mounted in the mullion profiles and in the transom profiles by their edges. The one or more mullion profiles extend vertically and are provided with an undercut groove on two opposite sides which has an access opening. The grooves form a rebate in which the rim of a panel is mounted. The undercut groove has an elongate cross section which is provided, at the one or several of the transverse ends, with a rounded section and/or which is free from roundings with a radius of less than 2 millimeters at one or several of the transverse ends.

A radiant panel having a U-shaped channel or groove with substantially parallel vertical sides. Because varied diameter tubing pressed into curved channels of varying radius will change their shape from round to oval by different amounts, channel width will be reduced at curved channel areas as appropriate, based on tubing size and channel radius. This reduction in curved channel width compared to straight channel width allows for a consistent friction force to be developed upon pressing the tubing into a channel. The depth of groove may be varied to allow for the increased vertical dimension of tubing which is deformed from round to oval by bending forces, so that tubing can be installed consistently flush with the surface of the radiant panel. Varying width and depth will also tend to maximize the contact area of tube to conductive surface, thereby improving the flow of heat from tube to radiant panel.
