摘要

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 efficiency. In fact traditional wall behaviour is very similar to the human skin, that works as an osmotic filter between body and environment. Moreover, the high 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 characterized by the use of osmotic performance fabric, combined with a selection of special glues and joined up with specifically designed devices. A large number of laboratory and on-site tests demonstrated that the wall-facing system prototyped supply good transpiration and waterproof performances, improving durability and reliability of the external surfaces of traditional buildings. A strong protection is assured, also in hard environmental conditions.
