Walls between the private Office and Open Office, and between the Board Room and Open Office, are described as including what feature to support glass and maintain openness?

• A. Glass walls between offices extending to the underside of the deck for lateral support
• B. Insulation for sound control
• C. Fire-rated drywall and seals
• D. Sound-damped glazing without deck support

Answer: (A)

The key idea is providing a stable yet open partition by giving the glass walls a solid, above-edge support. Extending glass walls from private offices and the board room to the underside of the deck creates continuous lateral support at the top, allowing large glass panels to span between structural elements with minimal framing. This preserves an open, transparent feel between spaces while ensuring the glass partitions stay stable under horizontal loads.

Insulation for sound control and fire-rated drywall with seals address acoustics and fire separation, not the structural support needed to keep glass walls stable and visually uninterrupted. Glass that is not supported by the deck would rely on heavier framing or could bow or rattle under load, defeating the goal of openness.
