Noise in a ward is treated as a finishes problem, and it is not: it is a mass-and-absorption problem, and a hard ceiling leaves nothing in the build-up to absorb it. We supply a glass-fibre panel that absorbs at NRC ≥ 0.90 while holding Class A fire classification and an antibacterial face.
It is a glass-fibre board at 100–150 kg/m³, finished as a ceiling panel rather than a wall or duct liner. Density in that band gives the board enough rigidity to stay flat across a grid bay while keeping the open structure that does the absorbing.
It is not a wipe-down plastic ceiling. Where the requirement is direct water spray, aggressive disinfectant and a sealed non-porous face, our GRP antibacterial panel is the right product and we will say so rather than sell this one into the wrong room.
Two properties it does hold: dimensional stability at high humidity — the panel is rated stable at RH 99 — and a face that is antibacterial above 99.99% against E. coli and S. aureus to GB/T 31402, with anti-mould Grade 0 to GJB 150.10A.
Every figure below carries the standard it was tested to. Where a figure is not on a report, it is not in the table.
| Product | Parameter | Result | Test standard |
|---|---|---|---|
| Glass-fibre acoustic ceiling panel | Sound absorption | NRC ≥ 0.90 | EN ISO 354 / GB/T 20247 |
| Glass-fibre acoustic ceiling panel | Fire classification | Class A | EN 13501-1 / GB 8624 |
| Glass-fibre acoustic ceiling panel | Antibacterial, E. coli & S. aureus | > 99.99% | GB/T 31402 |
| Glass-fibre acoustic ceiling panel | Anti-mould | Grade 0 | GJB 150.10A |
| Glass-fibre acoustic ceiling panel | Moisture resistance | Stable at RH 99 | Report on request |
| Glass-fibre acoustic ceiling panel | Density | 100–150 kg/m³ | Report on request |
| Glass-fibre acoustic ceiling panel | Environmental label | China 10-Ring eco-label | China environmental labelling programme |
The three ceilings below are the ones specified into the same rooms, so the comparison is worth putting in front of a value-engineering review. The alternative within our own range is the GRP antibacterial ceiling.
| Glass-fibre acoustic | Mineral fibre (typical) | Gypsum board (typical) | |
|---|---|---|---|
| Sound absorption | NRC ≥ 0.90 | Moderate to good | Low |
| Fire | Class A | Varies by product | Board and framing vary |
| Humidity | Stable at RH 99 | Absorbs, then sags | Softens, crumbles |
| Antibacterial | > 99.99% | Add-on coatings only | None inherent |
| Cleaning | Wipe and damp mop | Face damaged by scrubbing | Repaint cycle |
The comparison that decides a hospital ceiling is not the panel alone. A mineral fibre ceiling that sags above a live ward is replaced with containment, night shifts and patients moved; that cost never appears on the panel line of the quotation, but it is paid inside the same ten years.
This is the only range we supply with CE marking. The classification behind it is Class A to EN 13501-1, and the file holds SGS reports and Korean fire certification alongside the declaration of performance.
The same policy applies in the other direction: our GRP antibacterial ceiling and our medical clean wall panel do not carry CE marking, and we say that before it is written into a specification rather than after. What those ranges do carry is their own fire, antibacterial and physical test reports, issued in English.
If a consultant needs the declaration and the classification report to close a submittal, ask at tender stage. They are released against a project reference with the quotation.
Absorption earns its cost in rooms where speech, alarms and trolley noise have nowhere to go:
Humidity is the usual objection. Rated stable at RH 99, the panel does not need substituting on moisture grounds in a humid plant room or a therapy pool hall — but check the cleaning regime first, because that is where the choice between this panel and GRP actually changes.
NRC ≥ 0.90 to EN ISO 354 and GB/T 20247. The figure is measured on a defined mounting, so ask for the mounting condition with the report: a deep void over a sealed plenum does not behave like a shallow one, and the report states which was tested.
It is stable at RH 99 and Grade 0 anti-mould to GJB 150.10A, which covers humid air and condensation. It is not a hose-down panel: where walls and ceilings are washed with disinfectant under pressure, specify GRP.
Yes, in English, at submittal stage and against a project reference. If your consultant holds a clause we have not been tested against, send the clause and we answer it in writing rather than with a brochure.
We return the NRC report, the fire classification and a CAD detail of the grid for your submittal.
