Thermal Bridges in Building Construction—3D Iron Bar Through Insulation Layer

Model ID: 12575


This model studies the heat conduction in a thermal bridge made up of an iron bar and an insulation layer that separates a hot internal side from a cold external side. The heat flux between internal and external side and the maximum temperature on the external wall are compared them with published values.

This example corresponds to the case 4 described in the European standard EN ISO 10211:2007 for thermal bridges in building constructions.

COMSOL Multiphysics passes successfully all the test cases described by the standard and is hence classified as a three-dimensional steady-state high precision method.
