Abstract(s)
Ao percorrermos as cidades portuguesas, deparámo-nos frequentemente com fachadas de
edifícios muito degradadas, não só de edifícios antigos, mas também de edifícios recentes
(construção edificada a partir do início da década de 70).
A presença de anomalias nas fachadas, para além de ser esteticamente desagradável na
paisagem urbana, pode também potenciar a degradação prematura da envolvente vertical
dos edifícios, deixando estas de desempenhar satisfatoriamente as funções de
impermeabilidade e eficiência térmica.
Tem-se assistido nas últimas décadas em Portugal, não só a uma evolução das técnicas
construtivas das fachadas face à crescente exigência da qualidade dos edifícios, mas
também a uma crescente utilização de novos revestimentos, nomeadamente, o sistema de
isolamento térmico pelo exterior, conhecido pela sigla inglesa ETICS (External Thermal
Insulation Composite System) e designado por “revestimento delgado armado sobre
isolante”.
O principal objectivo da presente dissertação consiste no desenvolvimento e aplicação de
uma proposta de metodologia para análise da patologia de fachadas de edifícios recentes
com sistema ETICS, que gradualmente tem vindo a implantar-se em Portugal como uma
das soluções de carácter inovador de isolamento térmico e de protecção higrométrica da
envolvente vertical opaca dos edifícios.
When we go through Portuguese cities, we came across easily with very degraded facades of buildings, not only of old buildings, but also of recent buildings (construction built from the beginning of the 70s). The presence of anomalies in the buildings facades, besides being unsightly in the urban landscape, it can also originate the premature degradation of the facades, affecting their performance, in particular, the functions of waterproof and thermal efficiency. We have seen in recent decades in Portugal, not only to an evolution of the constructive techniques of the facades face to the increasing requirement of the quality of the buildings, but also to an increasing use of new coatings, namely, the outside thermal insulation system, known by acronym English ETICS (External Thermal Insulation Composite System). The main objective of the present dissertation consists of the development and application of a proposal of methodology for analysis of the pathology of façades for recent buildings with ETICS that gradually has come to implant itself in Portugal as one of the innovative solutions of insulation thermal and of hygrometric protection of the buildings facades.
