The developed system corresponds to multifunctional prefabricated modular elements
that combine an insulation layer with a cast coating material for exterior that can imitate stone or
concrete. These systems need auxiliary elements of fixing to connect them mechanically to the
structural wall of the building, in order to ensure its stability, using anchorage, profiles, rails, among
others. The use of these systems connected to the coating interrupts the continuity of thermal
insulation, causing additional heat losses through linear and point thermal bridges, having
an detrimental effect on thermal performance of the system. The development of fixing of present
multifunctional panels was based on the evaluation and adoption of appropriate solutions in order to
minimize thermal bridges and reinforce the stability of the panel. For evaluation purposes some
models are evaluated, with different connecting systems, configurations and different materials such
as aluminium, stainless steel, galvanized steel and Glass Fibre Reinforced Polymer (GFRP) profiles.
The quantification of thermal bridges, for evaluation of thermal performance, has been made using
computing programs, HEAT2 and HEAT3. The evaluation of a system developed in this
research work, i.e. incorporating profiles in thermal insulation, shows a good thermal resistance
contributing significantly to the thermal insulation and energy conservation in building.
