Scientific summary of the project:
The increase of the energy performance of buildings is a crucial objective for all European countries, in order to allow a sustainable development. Many new buildings are designed and constructed with the aim of achieving high energy efficiency. The current trend is to increase the insulation of buildings in order to reduce energy waste.
In this context, external thermal insulation (ETI) has been widely developed (with two types: ventilated cladding and external thermal insulation composite systems, ETICS). ETI has many advantages for the construction of new buildings and is one of the most effective ways to renovate existing buildings, limiting thermal bridges and keeping the interior space constant. This potentially translates into an increase in the combustible mass and fire propagation on the facades, especially for some of the insulation materials used (PE, EPS, PIR, PUR), which are highly combustible.
In order to analyze and improve the fire safety of external insulation systems, tests will be carried out at different scales: small, medium and large. Each one has specific advantages and limitations. Modeling and simulation with adapted and validated tools are also necessary and complementary in order to determine parameters that are difficult to measure and to predict configurations and scenarios that are difficult to reproduce in experimental tests.
