Insulation of pillars, architraves, inter-floor beams, overhanging components and radiator niches

The loss of heat through the structural components of a building, THERMAL BRIDGES, can reach and exceed 20% of the total dispersion, and is the cause of interior condensates, stains and mould, with subsequent deterioration of the building parts. The adjustment of thermal bridges, as set out by regulations on energy efficiency, is obtained by placing Celenit panels within the formwork which contains the casting. These will then remain permanently connected with the casting itself. In this way, a balance is obtained between the insulating properties of the wall and the concrete sections. It is suggested that plastic or metal fasteners be used with multi-layered panels (Celenit P3, Celenit L3). These will remain incorporated in the casting. Then, plaster reinforced with a glass fibre net is applied.

Figure 1

25 mm thick Celenit P3 panels used to insulate radiator niches, including sides and sills, eliminate thermal bridge. Their finishing will be the same as that of the wall.

Figure 2

Celenit floorings cast on site are used for the horizontal structure, while for the vertical parapet a permanent formwork made with 50 mm thick Celenit N, panels, is used. This adjusts the substantial heat loss of this particular overhanging architectural component.

Figure 3

Thermal bridges on inter-floor beams and pillars can be adjusted, at the casting stage, by inserting Celenit N or Celenit P3 panels in the formwork. For this specific use, made-to-measure strips are supplied by the company.

An arcade insulated with 50mm thick Celenit P3 panels, placed on the containment formwork before the casting - this operation produces particularly economic results with regard to the reduction in energy consumption and the protection of the structures.

Figure 5

To insulate this thermal bridge, 35mm thick Celenit P3 panels were used fixed with plastic anchorages.
