What Is Structural Glazing? A Guide for Homeowners and Architects
Structural glazing comes up often in conversations with architects designing contemporary villas and commercial facades — but the term is frequently used loosely. Here's a straightforward explanation of what it actually means and when it's the right specification.
The basic idea
In conventional glazing, glass panels sit inside a visible frame that holds them mechanically — you can see the frame from outside, framing each pane. Structural glazing instead bonds the glass to a supporting structure using high-strength structural silicone, so from the outside the building presents as a continuous glass surface with minimal or no visible frame.
Where it's typically used
- Commercial and hospitality facades wanting a fully glazed, frameless appearance
- Large architectural feature walls
- Curtain wall systems on multi-storey buildings
It's less commonly used for standard residential windows, where the cost and engineering requirements aren't usually justified by a typical-sized opening.
What to consider before specifying it
Structural glazing requires more rigorous engineering than standard framed glazing — wind load, thermal movement and the structural silicone's long-term performance all need proper calculation, ideally by a system engineer with experience in the specific product being used. It's also generally a higher-cost specification than standard framed glass, both in materials and installation expertise.
A related but different term: curtain walls
Structural glazing and curtain walls are often mentioned together but aren't the same thing — a curtain wall describes the overall non-structural facade system (which may or may not use structural glazing as its glazing method). We'll cover curtain walls in more depth in a separate article.
