Balcony slab – thermal bridges.

Another thermal bridge considered is the balcony slab.
For small balcony slabs, or located at a corner, consider the above as a 3D model. Here, the balcony slab was treated as extensive, and therefore as the source of the linear bridge.

Ul=(36,204 – 20,8305) /1/ 40 = 0,384 W / mK
attention: It is a complete linear bridge due to the ceiling and balcony. He was not separated (as in the previous example) on the "underside of the ceiling" and "top of the floor". However, it is necessary for the assessment of individual apartments or zones separated by ceilings.
attention: Balconies of small size or close to the corner of the building should be counted as spatial models, because their line work is disturbed.
attention: The isotherm diagram leaves some doubts, whether the range of the bridge was fully covered by the model. The calculations should be repeated by lengthening the vertical elements.
