Continuous system for coating exterior façade walls which provides a high degree of thermal efficiency in protecting the opaque region of the walls

The system consists of:

(1) rigid insulation boards glued to the cloth sturdy wall (masonry or concrete)

(2) coated with thin polymeric plaster, reinforced with glass fiber network

(3) Finished with decorative coating1

The Portuguese State published in compliance with the European Directive (2002/91/EC) on the energy performance of buildings, the Decree-Law 118/2013 establishing the Energy Certification of Buildings (SCE) and laying the foundations of two new regulations:

Regulamento de Desempenho Energético dos Edifícios de Habitação (REH) (regulado pelas Portarias n.º 349-B e C/2013)

Regulamento de Desempenho Energético dos Edifícios de Comércio e Serviços (RECS) (Portarias n.º 349-D e 353-A/2013)

referring to a series of dispatches from the General Directorate for Energy and Geology, which calculation methodologies, to adopt specific rules and also data, zoning and climatic parameters are set
