Original Abstract

The paper describes the testing of the tensile properties of silicone sealants applied to facade cladding materials. The test procedures followed steps defined in applicable technical standards in order to meet their requirements. Furthermore the paper describes the implementation of the tests according to the standards and their application in practice. For the experimental part, industrially produced neutral or universal silicon sealants from three different manufacturers were selected. The researchers also decided to choose silicon sealants from various price categories. The aim of the research was to determine any differences in the resistance of sealants to permanent extension maintained at normal or freezing temperatures. Samples of the following materials were used as facade cladding alternatives: composite aluminium panels, fibre-cement slates, ceramic tiles, fibrecement and compact tiles, metal plates without surface finish, artificial stone panels and thermowood facade panels. It was measured with putty consistency by construction materials. They were always tested in three test samples of each material. The test results have been evaluated and are displayed in a table that defines appropriate and inappropriate combinations of facade materials and sealants. Only serie of all three test specimen that showed ability to satisfy all requirements had been evaluated as convenient otherwise the test specimens can not be recommended. The conclusion of the tests is that the choice of a suitable sealant is not straightforward and cannot be responsibly carried out without previous experience or measurements. The chosen test method has also revealed that there are significant performance differences between silicon sealants. Likewise, it seems to be a fact that the use of the most expensive sealants does not necessarily lead to the best results.
