An Architect’s Checklist for Specifying Glass Partitions
A practical specification checklist for glass partitions: performance targets, system, glass, doors, interfaces, compliance, manifestation and handover documentation.
Key takeaways
- State performance targets, not just products, in the specification.
- Define interfaces with ceilings, floors, walls and services.
- Require test evidence matching the installed configuration.
- Include manifestation, documentation and maintenance.
Performance targets
Start with what each partition must achieve: acoustic rating, fire rating, safety classification and any security or accessibility requirements. Our commercial interior glazing hub covers how we support each stage.
- Acoustic: lab Rw and, if required, on-site DnT,w target
- Fire: E or EI rating and duration, from the fire strategy
- Safety glass classification for critical locations
- Accessibility: door widths, forces, contrast
System and glass
- System family: frameless, framed, Crittall-style, demountable
- Profile width, depth and finish
- Glass type, thickness and build-up
- Decorative glass and integral blinds
- Joint type: silicone, polycarbonate strip, mullion
Doors and ironmongery
- Door type, size and swing
- Hardware, closers and locks
- Acoustic and fire seals
- Access control interfaces
Interfaces
Specify head details, including deflection and ceiling void treatment, base details on different floor finishes, wall and mullion junctions, and services coordination. See where acoustic performance is lost.
Compliance and documentation
Require test evidence for the specified configuration, manifestation to Approved Document K (see our manifestation guide), shop drawings for approval, and O&M manuals at handover.
Questions
Can you provide specification clauses?
Yes. We supply system data, details and suggested wording for your specification.
