The thermal linear bridges (PTL) are connection zones between different elements of the envelope of a building, which usually are designated for a increase of heat flux, and consequently, diminishes the interior surface’s temperatures, responsible for the occurrence of condensations. The heat flux which passes a PLT, in stationary regime, could be determined through the respective coefficient thermal linear transmission, “psi, calculated in accordance to the method recommended in the standard ISO 10211. This catalogue allows obtaining values of “psi” determined in accordance to the standard ISO 10211, to different kinds of PTL, having in consideration different constructive solutions, namely solutions in brick masonry and stone masonry, wood, concrete, among others. For each type of PTL the catalogue provides the respective profile of temperatures and the technical data sheet of the constructive solution. The user can also change the different parameters, such as thickness of the constructive elements (walls, pavements, and cover slabs) and/or thickness of the insulation layer.
