The effects of environmental impacts on durability of laminated glass plates with interlayers (SG, EVA, PVB)

Abstract

The durability of laminated glass is a relevant problem in modern structural engineering. This paper deals with the results of experiments on laminated glass durability focusing on the following impacts: temperature, humidity, UV radiation and combination of these impacts. The purpose of this research is to investigate the aspect of laminated glass durability in the framework of long-term tests. Three different interlayer laminates were used during the experiments: Polyvinyl butyral (PVB), Ethylene vinyl acetate (EVA), DuPont's SentryGlas ionoplast (SG) and 6 mm thick tempered Soda-Lime-Silica Glass. Tests for environmental condition impact and durability of laminated glass are foreseen according to standard (ISO 12543- 4:2011). Bending tests were carried out due to standard (EN 1288-3:2000). Brief graphical comparison of the experimental results is presented in the paper.
