What is the purpose of a "structural silicone sealant"?

The purpose of a structural silicone sealant is to bond glass to framing systems and to help weatherproof the structure. This type of sealant is designed to provide strength and stability, creating a secure attachment between the glass and the framing elements. It allows for the transfer of loads while also providing a barrier against water penetration, air infiltration, and environmental elements.

In glass installations, especially in curtain walls and other large glass structures, the structural silicone sealant plays a critical role in ensuring the integrity and durability of the building, contributing to the building's overall structural performance and energy efficiency. Its formulation typically allows for movement caused by thermal expansion and contraction while maintaining a reliable seal.
