Research summary: Verification of Adhesively Bonded Façade Joints

conference paper

English

This contribution presents an overall summary of three years of research. Focus was placed on an experimental testing of composite materials with wooden elements used as a cladding of vented façade systems with adhesively bonded joints. The potential of adhesive systems was verified through experimental measurements. Two test methods, defined by relevant European and Czech standards, were adopted and modified. Moreover, the frost resistance of some test specimens was determined by subjecting them to a cyclic action of freezing and thawing. Furthermore, implemented test methods also included conditioning of a group of test specimens with sudden temperature changes. Finally, the substructure bonding retention to the cladding and strength in shear in tension stress was tested. The obtained test results were compared and revealed that a crucial factor for the bonded joint is strength of the cladding material or of the substructure. Additionally, it was verified that any violation against the observance of technological discipline may weaken the functionality of the entire façade system.
