Meeting structural glazing performance standards around the world, structural glazing sealants from Dow enable architects to continue to enhance their building designs, contributing to visually stunning glass façades.

In 1971, Dow pioneered four-sided silicone structural glazing (SSG), which helped define today’s beautiful city skylines. We continue to bring innovations to the market that not only continue to inspire architectural creativity, but also contribute to the overall sustainability of the built environment. These innovations include:
