Acoustic Glass Partitions, UK-Wide
An acoustic glass partition is built specifically to block sound transfer between spaces — measured in decibels (dB) of noise reduction — rather than just to divide a room visually. Weldholm's WH-80 OFFICE holds up to 50dB, depending on infill, using a double-glazed cavity construction rather than a single sheet of glass.
What a dB rating actually means
| Reduction | What it means in practice |
|---|---|
| ~20-30dB | Normal speech is muffled but still audible next door |
| ~35-45dB | Loud speech becomes hard to make out |
| Up to 50dB | Loud conversation is barely perceptible next door |
WH-80 OFFICE reaches up to 50dB depending on the infill chosen.
Where acoustic partitioning is non-negotiable
Anywhere a conversation can't be allowed to carry:
- Meeting rooms and boardrooms where confidentiality matters
- HR, legal, and 1:1 spaces needing genuine privacy, not just a visual divide
- Focus rooms and quiet zones inside an open-plan office
- Reconfigurable layouts that still need to hold their sound rating after being moved
Sound insulation without losing the room
Acoustic performance in an internal wall usually comes at the cost of something else — thickness, cost, or flexibility. WH-80 OFFICE takes transparent or obscure infill and can incorporate internal louvers, with room inside the wall for electrical runs and standard power sockets, so specifying for sound doesn't mean giving up natural light, glazing, or outlets.

Acoustic performance across the range
| System | Acoustic performance | Best for |
|---|---|---|
| WH-80 OFFICE | Up to 50dB | Genuine sound privacy |
| WH-78EI | Not the primary spec | Fire compartmentation with clear sightlines |

Acoustic glazing, asked and answered
What does "dB" mean for an office partition?
dB (decibels) measures how much sound is blocked between two spaces — the higher the number, the more sound on one side is stopped from reaching the other.
How much sound insulation do I actually need for a meeting room?
It depends on what's being discussed and what's next door, but WH-80 OFFICE's range — up to 50dB depending on infill — covers most private-office and meeting-room requirements.
Does an acoustic partition mean losing natural light or glazing?
No — WH-80 OFFICE takes transparent or obscure infill, so acoustic performance doesn't require solid panels.
Can an acoustic partition be moved later without losing its rating?
Yes — WH-80 OFFICE is built to be reconfigured without a full rebuild, keeping its acoustic performance intact after relocation.
