Abstract

The growth in the use of non-adhered coatings (ventilated facades) in Brazilian constructions in recent years is notorious, making it necessary to evaluate their performance in relation to the requirements of the ABNT NBR 15575-4 standard. In this context, this work aims to present the normative requirements that can be verified in the non-adhered coating system and to discuss the need for standardization of the prototypes to perform the tests, also considering the fixations and bindings, justifying the adopted model. The work was carried out through the case study of thirty tests carried out in the laboratory, which had their prototypes defined by the test contractor. The objective of this work is to evaluate the results obtained in view of the requirements of the ABNT NBR 15575-4 standard, if the size of the prototypes and dimensions of the plates may cause possible interferences in the results.
