During actual construction, when is it appropriate to use structural glazing silicone sealant?

Skylights, Canopies, and Roof Windows:

These areas are typically sloped or horizontal, subjecting the glass to greater self-weight, snow loads, and maintenance loads. Structural adhesives are used here to bond glass panels to supporting structures, preventing glass detachment due to external forces and ensuring the highest safety standards.

Glass Curtain Wall Projects:

Used for structural bonding between curtain wall glass and aluminum profiles or metal frames.

It is especially suitable for hidden frame and semi-hidden frame curtain walls, where long-term resistance to wind load, self-weight, and stresses caused by temperature changes is required.

Bonding of Large Components:
Such as fixing aluminum composite panels, stone, and metal panels to the main structure for exterior wall decoration.
It requires high strength, weather resistance, and long-term adhesion.

Large Suspended or Load-Bearing Indoor Structures:

For example, the bonding and fixing of large indoor glass partitions, glass stair treads, and glass balustrades (non-railing type). When the glass is required to withstand human impact loads, structural sealant must also be used.

Projects Requiring Safety Certification

Structural sealants are typically tested in accordance with standards such as GB 16776-2005, ASTM, and ETAG, and are used in construction projects with extremely high safety requirements.

In all. For any parts that need to bear loads, withstand pressure, and ensure high safety, structural sealant should be used rather than just a regular silicone sealant.

This decision must be made by professional designers or engineers based on calculations, and should never be made solely on experience.
