Enhanced Edge Stability with Structural Glass Laminates

Valerie Block, DuPont Glass Laminating Solutions

Traditional glass laminates can develop edge defects after installation. This concern has existed for many years. Since the introduction of the SentryGlas® Plus structural interlayer, initially to address the needs of the hurricane market, extensive testing has been done to understand this material’s performance with respect to the formation of edge defects. Studies involving both open edge and silicone butt-joined laminates show no signs of appreciable edge delamination after seven years of exposure. Actual building installations—in extreme weather conditions ranging from high humidity and temperature of Florida to the bitter cold of Minnesota, have been studied. Additionally, testing has been done to examine an expanded range of contact materials and the interlayer material itself in order to assess edge stability performance of these laminates.
