Frameless Glass Partitions: Spec, Detail and Finish
Specifying frameless glass partitions: glass types, joints, head and base channels, doors, acoustics and finishing details.
Key takeaways
- Frameless panels sit in slim channels with clear joints.
- Polycarbonate strips or silicone close the vertical joints.
- Recessed channels give the cleanest finish.
- Acoustic laminated glass improves privacy.
How frameless systems are built
Each panel sits in a slim channel at head and base, with clear vertical joints. Our frameless and demountable hub compares frameless and demountable systems.
Joints
Silicone joints are almost invisible but permanent. Clear polycarbonate jointing strips are tidier and allow panels to be removed. Both should be consistent, plumb and clean.
Head and base channels
Surface-mounted channels are quick and economical; recessed channels hide in the ceiling and floor for a cleaner look. Deflection allowance at the head is essential under concrete slabs.
Doors and acoustics
Frameless doors give a clean look, but framed or sealed doors perform better acoustically. See acoustic glass partitions.
Questions
How tall can frameless panels be?
Commonly up to around 3 m, and taller with thicker glass and specialist systems.
