In this study, we produced two types of claddings, representing the element of the ventilated façade. The first façade cladding was a cement-bonded particleboard, surfaced with a low-pressure laminate, while the second was a waterproof plywood board, coated with a stain-coating system. Both types of façade claddings were exposed to processes of artificial accelerated aging and temperature cycling tests, as well as to biotic factors, in order to simulate the conditions in real use. Changes in climatic conditions and other factors of the performed tests had a larger influence on the behaviour and properties of the surface finished plywood board. Both types of composites were not susceptible to infection with wood decay and blue-stain fungi. According to the results of the research, both types of claddings are suitable for the intended use as the outer element of a ventilated façade.
