Structural glazing uses a designed silicone joint to retain glass or opaque panels on a supporting frame. By reducing or eliminating external pressure caps, it can create a smooth, continuous surface with narrow and consistent joints.
More than an adhesive
The structural sealant is sized to transfer wind loads while accommodating thermal and building movement. Bite, thickness, joint shape, glass dimensions, edge clearance, setting blocks, and mechanical safety provisions are all coordinated through engineering.
Compatibility and preparation
Silicone, glass coatings, spacers, gaskets, backer materials, and aluminum finishes must be tested for adhesion and compatibility. Clean surfaces, controlled application, batch records, cure checks, and trained workmanship are central to quality.
Verification
Project-specific calculations, laboratory reviews, factory quality procedures, and field inspection provide confidence that the installed joint matches the tested design. Unapproved substitutions can change adhesion or load transfer and should never be treated casually.
