Abstract: 
This chapter outlines important features of the environmental degradation factors, methods for their characterisation, and their effects on the degradation of the performance of sealed joints. The review follows the classification suggested earlier in this report, i.e. weathering and biological factors are discussed separately. The weathering factors responsible for the degradation of sealants are solar radiation; water in its various physical forms; normal air constituents; air contaminants; temperature and its cycles; and wind. Biological degradation is caused by micro-biological factors, such as bacteria, fungi, and algae, and by macro-biological factors, such as plants, animals and humans.
