L’obiettivo dell’isolamento termico è quello di ottimizzare i consumi delle risorse energetiche necessarie al riscaldamento e raffrescamento degli edifici, riducendo l’inquinamento atmosferico dovuto all’ emissione di gas inquinanti derivanti dai processi di combustione. L’isolamento termico produce un aumento del benessere e del comfort abitativo grazie al ridotto scambio termico tra l’interno e l’esterno dell’edificio, riducendo i costi e risolvendo i problemi di condensa e formazione di muffe sulle pareti dell’abitazione. Dal punto di vista energetico, il miglior isolamento è quello esterno, detto a cappotto: il calore prodotto all’interno durante la stagione invernale rimane più a lungo nella struttura dell’edificio, mentre in estate si evita un eccessivo riscaldamento. Gli impianti a cappotto sono costituiti dall’accoppiamento di diversi strati di materiale. Lo strato isolante è solitamente di tipo plastico espanso. L’impiego di tali materiali necessita un’opportuna progettazione a causa delle problematiche legate all’impianto stesso. In questo lavoro di tesi, in particolare ,verrà analizzata la reazione al fuoco del cappotto termico prima tramite i riferimenti normativi nazionali e internazionali e successivamente tramite casi studio relativi allo stato dell’arte della progettazione antincendio

Abstract
The aim of thermal insulation is to optimise the consumption of energetic resources necessary for the heating and cooling of buildings. As a result thermal insulation reduces atmospheric pollution caused by the emission of gases combustion processes. Thermal insulation produces an increase in well-being and living comfort as it reduces heat exchange between the inside and the outside of the building. Moreover this technique allows to lower costs and solve problems like condensation and mold formation. Whit regard to energy consumption, the best insulation is the external one: the coat: as a matter of fact, thanks to the coat, the heat produced during winter is trapped inside the building for longer periods, while in summer this kind of insulation prevents from excessive heating. The overcoating systems are made up of couplings of several layers of material. The insulating layer is usually made of expanded plastic type. The use of such materials requires an appropriate project because of the problems related to the insulation system itself. This work presents an analysis of the thermal coat reaction to fire based both on national and international normative references and taking into consideration some case studies related to the state of art of the fire protection design.| File | Dimensione | Formato | |
