How to choose silicone sealant based on seam displacement

Building joints expand and contract with temperature changes and structural deformation, and the sealant’s movement capabilities need to match the joint design. When selecting a weather-resistant sealant, joint width, adhesive layer thickness and expected movement should also be considered.

Dimensional and installation deviations during construction will also affect the actual deformation the joints endure. This article introduces the selection ideas around displacement levels and joint design, and displays Glorystar curtain wall sealing products.
