Abstract

Osmotic fabrics for historical building external surfaces protection E. Attaianese, G. Caterina & G. Duca CORITED Consortium, Naples, Italy Abstract The analysis of historical building behaviour demonstrates that control of external wall performance is very important because the chain environment - building- degradation depends on its eficiency. In fact traditional wall behaviour is very similar to the human skin, that works as an osmotic filter between body and environment. Moreover, the hgh complexity of traditional buildings usually produces irregular shapes and surfaces. In that context the main features required for the new facing system were: waterproofness, air permeability, chemical compatibility to the support material, morphological and geometrical compatibility to the support and reversibility. The prototype has been obtained by a sort of hybridisation process of different kinds of materials in a composite system that can be customized depending on surface conditions. It is mainly c
