Abstract

This article deals with the solution of sealing joints of materials in which the sealed joint may be damaged due to temperature changes. In this case, glass cement is selected as the base material. Together with selected sealants, test specimens are made from it, which are tested according to the valid European standard ČSN EN ISO 9047 Building construction - Sealants - Determination of adhesion and cohesion of sealants at variable temperatures. The results of this testing are evaluated by visual inspection and re-measurement of any violations of the sliding scale. Based on the evaluation of the given test results, it is not possible to recommend any of the tested sealants for sealing glass-cement base materials.
