It is necessary to point out that the statistics that are exposed here
and the data contributed refer, exclusively, to building works designed and
directed, in which at least one architect has taken part. The pathologies in the light
facades (building external cladding that, by itself and together with the interior
layer, contributes all the functions requirable to an external envelope regarding
stability, security, sealing, insulation and solar control) present different symptoms
that rarely have a unique cause and generally are produced by the concurrence of
several of them. At the same time, one same cause can provoke different defects,
and therefore, different symptoms. The origin of the pathologies is found in any
of the phases of its creation, from the project to the end of the useful life of the
facade: Architectural and Technical Project, Manufacture, Transport and Storage,
Assembly and Use and Maintenance. It is in this process where the different
processed judicial reports are studied, regarding the systems and materials that
are involved: Structural Elements, Connectors, Anchorages, Glazing and Plates
and Panels. The ones that affect those we called light, slightly more than 7.50 per
cent, from which we should remark that a great part of their surfaces (affected)
have glass as the main component.
