In window construction, what term refers to the piece that holds panes in place?

• A. A decorative trim
• B. To hold panes within a window wall
• C. A primary structural member
• D. A sealant

Answer: (B)

The essential idea is the component that secures the glass inside the window frame. It is described as holding panes within a window wall, which directly matches the function of the part that keeps the glass in place. Decorative trim is cosmetic and doesn’t secure the glass, a primary structural member carries loads but isn’t about glass retention, and sealant merely seals joints rather than holding the pane itself. So the description of holding panes within the window wall best captures the role of that piece.
