Window Wall

Definition

A Window Wall is the opening in a wall surface that contains a window assembly or wall of assemblies. Often referred to loosely as tube framing or storefront.

Purpose

The purpose of a window wall is to provide a large, continuous area of glazing that allows for ample natural light and expansive views, enhancing the aesthetic and functional qualities of a building.

Examples of Use

• Commercial Storefronts: Large glass windows in retail stores to display merchandise.
• Office Buildings: Creating bright, open workspaces with extensive glazing.
• Residential High-Rises: Providing panoramic views and natural light in apartment units.

Related Terms

• Curtain Wall: A non-structural outer covering of a building with large areas of glass.
• Storefront: The front facade of a retail store with large windows for display.
• Glazing: The glass panes used in window and curtain wall systems.

Notes

Window walls must be designed to handle structural loads, thermal expansion, and water infiltration. They often require specialized framing systems to support the glass and provide stability.
