Original Abstract

This contribution deals with the possible options for a usage of cement-bonded particleboard, “Cetris”, as a sheathing of a vented façade system with bonded joints. The potential of bonded joints in combination with composite cladding material was studied and described in more detail as well as verified through experimental measurements. Two test methods, defined by relevant European standards, were adopted. Firstly, the frost resistance of the test specimens was determined by subjecting them to a cyclic action of freezing and thawing, i.e. immersion into a water bath at (20 ± 3) °C for 6 hours and subsequent freezing to (‒20 ± 2) °C for 18 hours within 15 cycles. The second test method includes conditioning of all test specimens with sudden temperature changes, heating to (70 ± 3) °C and subsequent cooling to (20 ± 2) °C, within 25 cycles. Subsequently, the substructure bonding retention to the cladding and strength in shear in tension stress was verified. It was observed that the lap shear strength as well as the tensile properties of test specimens were enhanced by exposure to freezing and thawing cycles. The obtained test results proved the fact that bonded joints are more than suitable equivalent to the mechanical joints and show that the crucial factor for the bonded joint is the strength of the cladding material.
