Abstract: In Brazil, innovative building products are described as those for which prescriptive technical standards do not yet exist. These products need to be evaluated by a technical institute accredited to participate in the National System of Technical Assessment of Innovative Building Products (SiNAT). This is the case even if such products have been employed in other countries, since Brazilian conditions must also be considered. This paper aims to demonstrate an approach to performing a technical assessment of the durability of innovative building products, considering Brazilian exposure conditions. The example used consists of PVC components used as stay-in-place forms and finishing of concrete walls. The paper is based on researches conducted by CETAC/IPT supported by some companies. The following tests were carried out: hygrothermal shock (heat and rain) test to evaluate the durability of a wall with PVC finishing; mechanical performance of the PVC components both before and after accelerated ageing by UV exposure; and natural ageing and accelerated ageing trials to evaluate the color change of the PVC finishing. The approach presented for a durability assessment was shown to be adequate and the tests results were satisfactory. Further research considering longer natural exposure and also the application of PVC as finishing in a real building in normal use is still necessary.
