Frequently Asked Questions
What is structural glazing sealant used for?
It bonds glass to a metal frame so the glass carries designed loads as part of the building envelope. Use it for glass-to-frame assembly where the joint takes structural load, not just a weather seal. Each product has its own approved use conditions.
Which sealants in this collection handle structural loads?
Dowsil 795 covers structural and non-structural glazing and architectural panel attachment. SA N60 covers structural and fin glazing between glass and metal frames. Bostik V60 covers two-sided structural and fin glazing. Check the manufacturer approval for your joint before you use it.
Can I use Selsil Ultra Clear for structural glass work?
Selsil Ultra Clear suits glass-and-metal connection joints, window frames, and aluminium assemblies. It does not carry an explicit structural approval like Dowsil 795 or SA N60. Use it where the joint does not take structural load.
Do I need manufacturer approval before I use these sealants structurally?
Yes. Structural glazing depends on the whole system: joint design, glass, frame, movement, wind load, surface preparation, cure conditions, and the manufacturer's written approval. A sealant with the right description still needs project review before it goes into a load-bearing joint.
What makes a structural glazing joint fail?
The usual causes are joint movement beyond what the sealant can take, poor surface preparation, wrong bead size, or cure conditions the product was not designed for. The sealant is one part of the system. Get the joint design and manufacturer approval right first.
Are there structural sealants I should not use on four sides?
Bostik V60 covers two-sided structural and fin glazing. Four-sided structural use needs manufacturer consultation. An approval for two sides does not cover four. Check the written approval for your joint.
