1. Introduction

Partitions define space, provide acoustic separation and can carry finishes. Systems vary from lightweight gypsum and glass partitions to heavy‑duty masonry‑like panels. Selection is driven by acoustic or thermal requirement, fire rating, service penetrations, and flexibility.

SpecX quick selector

  • 100 mm gypsum partition: 2 × 12.5 mm boards each side + 50 mm studs + 50 mm mineral wool, STC ≥ 45, 1 h FR where noted
  • 10 mm toughened glass partition with patch fittings; perimeter acoustic seal; doors with floor spring
  • 75 mm cement board partition in wet areas on GI studs with PVC trims; sealant at perimeters
  • HPL panel cladding on aluminum sub‑frame with concealed clips for service corridors

3. Selection criteria

  • Acoustic STC target (e.g., 35/45/55 dB)
  • Fire rating requirement (e.g., 1-hour): choose corresponding assembly
  • Services requirement: if heavy MEP runs through partitions choose larger cavity or service risers
  • Reconfigurability: modular systems allow future layout changes

4. Glass partition considerations

  • Safety: toughened or laminated glass per IS 2553 / EN standards
  • Framing: patch fittings, U-channels, or structural silicone glazed (SSG) systems
  • Acoustic: laminated glass with acoustic PVB or double-glazed assemblies

5. Panel / modular wall systems

  • HPL / laminate panels: good for quick aesthetics & stain resistance
  • Metal / composite panels: durable, suitable for service corridors, wet environments
  • Timber / veneer: high aesthetics, sensitive to moisture & needs proper sealing

6. Performance & testing

  • STC (airborne sound) — ISO 717 / ASTM E413 tests
  • Impact resistance & durability — EN 1195 / local standards where applicable
  • Fire resistance — tested assemblies (1hr/2hr) must have report

7. Typical BOQ lines

  • “Supply & fix 100 mm gypsum partition with double layer 12.5 mm board each side, mineral wool infill, GI studs — m².”
  • “Supply & install 10 mm toughened glass partition with patch fittings & aluminum thresholds — m².”

8. QA / QC checklist

  • Check stud & channel spacing.
  • Check acoustic infill density & continuity.
  • Verify glass edge finish & toughening certificate.
  • Check sealant & perimeter acoustic sealing.
⚠️

Common failures (quick scan)

  • Leaks at perimeter joints → incomplete sealant or gaskets
  • Low STC achieved → missing or low-density acoustic infill
  • Glass edge chips → poor edge finishing or handling
  • Fire rating invalidated → unsealed penetrations and wrong board layering
