Glass Shop Drawings for Interior Glass: A Guide

In the modern architectural and interior design world, interior glass plays a pivotal role in shaping elegant, open, and light-filled environments. From frameless glass partitions in offices to decorative glass walls in residential spaces, the demand for precision in execution is higher than ever. One of the most crucial elements in ensuring a successful installation of interior glass systems is the glass shop drawing. Glass shop drawings for interior applications serve as a bridge between the conceptual design and actual fabrication/installation.

What are Glass Shop Drawings for Interior Glass?

Glass shop drawings are detailed, scaled technical drawings that provide exact specifications for the fabrication and installation of glass elements used inside a building. Unlike architectural drawings that focus on design intent, shop drawings offer installation-specific details and fabrication guidelines. 

When applied to interior glass, these drawings cover a variety of elements such as: 

  • Frameless glass partitions 
  • Glass office enclosures 
  • Interior glass doors (pivot, sliding, or swing) 
  • Glass railings and balustrades 
  • Decorative and etched glass panels 
  • Glass wall systems with aluminum or stainless steel framing 

Each shop drawing includes dimensions, cutouts for hardware, edge finishes, types of fittings, tolerances, anchoring details, and interfaces with adjoining materials like gypsum walls, wood trims, or ceilings. 

Common Types of Interior Glass Systems and Their Drawing Needs

1. Frameless Glass Partition Systems – Drawing Needs Explained

Frameless glass partitions depend entirely on precise glass cutting and hardware placement. Shop drawings must be highly accurate, as even small misalignments can cause fitting failures. 

Key Drawing Requirements:

  • Glass Panel Sizes: Exact dimensions of each glass panel with height, width, and thickness (typically 10mm–12mm toughened). Any tolerance (e.g., ±1mm) should be specified. 
  • Joint Details: Silicone or dry-joint gaskets between panels need to be shown with gap widths (commonly 2mm–5mm). 
  • Edge Finishing: Polish type (flat-polished, chamfered), especially for exposed edges. 
  • Hardware Details: Patch fittings, clamps, and spider brackets must be placed precisely with centerline locations, hole cutouts, and bolt types shown in detail. 
  • Mounting Channels: Cross-sections of the top and bottom channels (U-profiles) including material type (e.g., aluminum), dimensions, and anchoring. 
  • Elevations and Plans: Full front view and plan view indicating the layout of all glass panels, doors, and fixed components. 
  • Annotations: Clear notations for glass type (clear, frosted), safety labels, and any special treatments like sandblasting or acid-etching. 

2. Framed Glass Partition Systems – Drawing Needs Explained

Framed systems involve both glass and structural framing. Drawings must coordinate metal framing profiles and glass positioning. 

Key Drawing Requirements:

  • Glass Panel Layouts: Shop drawings must reflect panel-by-panel glass sizes, often with separate IDs and sequencing notes for modular assembly. 
  • Framing Details: Vertical mullions and horizontal transoms (aluminum or steel) with full cross-sectional profiles, wall fixing methods, and gasket insertions. 
  • System Interface: Drawings should indicate how the frame connects to the ceiling, wall, and floor—especially important in floating ceiling conditions. 
  • Door Integration: If doors are included, provide detailed views of door frame, hinges, lockset, threshold, and swing clearance. 
  • Finish Notations: Surface finishes (e.g., powder coat RAL colors, anodizing) must be noted clearly with surface treatment specifications. 
  • Isometric or Exploded Views: These help installers visualize the assembly order and orientation of profiles, glass, and gaskets. 

3. Sliding Glass Door Systems – Drawing Needs Explained

Sliding systems require specialized drawings that focus on movement, hardware interaction, and spatial clearance. 

Key Drawing Requirements:

  • Track and Roller Systems: Detailed top track sections showing roller brackets, channel dimensions, material specifications (stainless steel/aluminum), and anchor types. 
  • Glass Cut-Outs: Cut-out diagrams for handles, bottom guides, locks, and stoppers—with exact placement and hole size. 
  • Sliding Path and Overlap: Plan view with opening and closing positions, overlapping zones, and safety buffers. 
  • Elevation Drawings: Indicate total panel height, handle height, and alignment with adjacent fixed panels. 
  • Installation Views: Cross-section through the ceiling or soffit to show how track is hidden or exposed. 
  • Stopper Mechanisms: Locations of mechanical stoppers and soft-closing mechanisms, if applicable. 

 

4. Glass Swing Door Systems – Drawing Needs Explained

Swing (hinged) doors need very precise hardware positioning and safety clearances to avoid clashes and provide smooth operation. 

Key Drawing Requirements:

  • Door Leaf Dimensions: Width, height, thickness, and edge finish of the glass door. 
  • Hinge/Pivot Details: Floor spring, wall-hinge, or patch pivot placement with centerline-to-edge distances and mechanical anchor details. 
  • Opening Arc: Plan view showing door swing (90°, 180°) and necessary clearance from walls or adjacent panels. 
  • Handle and Lock Cut-Outs: Hole patterns and dimensions for D-handles, deadbolts, latches, and pull bars. 
  • Side and Top Panels: If present, their fixing details and integration with the door must be clearly shown. 
  • Sealing Details: Gaskets, brush seals, or drop seals for acoustic or privacy control. 

5. Glass Shower Enclosures – Drawing Needs Explained

Shower enclosures require water-tight construction, so shop drawings must detail all potential leakage points and proper slopes. 

Key Drawing Requirements:

  • Glass Panel Configuration: Layout of fixed panels, hinged doors, corner joints—plan and elevation views. 
  • Slope and Curb Detail: Shower curb cross-section with slope direction and angle to ensure proper water runoff. 
  • Sealants and Gaskets: Detailed view showing vertical and horizontal seals, magnetic strip placements, and overlap zones. 
  • Cut-Outs for Accessories: Cut-outs for towel bars, knobs, and hinges with spacing from edges and floor. 
  • Connection to Walls/Floor: Anchoring methods for hinges or U-channels, including waterproofing precautions (e.g., silicone sealing). 
  • Door Swing or Slide Mechanism: Full arc diagrams and limits for safe operation. 

 

6. Switchable Smart Glass Systems – Drawing Needs Explained

Smart glass systems involve electrical components, requiring coordination between civil and electrical drawings. 

Key Drawing Requirements:
