Ceiling selection in a hospital or a laboratory comes down to one question: is this room’s problem moisture, or noise? Our two ranges answer those separately, and we would rather you specified the right one than bought both.
The GRP antibacterial panel is a rigid glass-fibre reinforced polymer panel. It is specified where the room gets wet, gets cleaned hard, or both: 0.3% water absorption, resistance to strong acids and alkalis, Barcol 86 HBa surface hardness, and A2-S2,d0,t0 to EN 13501-1.
The glass-fibre acoustic panel is a porous absorber. It is specified where the problem is sound: NRC ≥ 0.90 to EN ISO 354, Class A to EN 13501-1 / GB 8624, antibacterial performance above 99.99% to GB/T 31402, and anti-mould Grade 0 to GJB 150.10A.
The two properties fight each other: a dense sealed panel reflects sound back into the room, and an open absorbing panel is the one that takes on moisture. No single ceiling is good at both, which is why we make two.
Values carry their standard. Where the column reads “report on request”, the report travels with the quotation.

Read the room’s dominant failure mode, not the ceiling’s marketing. A ward where noise travels between bays needs absorption; a wash-down room where a ceiling sags after two years needs a sealed, low-absorption face.

|---|---|---|---|---|
| Primary driver | Moisture, cleaning | Noise | Cost | Flat finish |

| Water absorption | 0.3% | Stable at RH 99 | Absorbs, sags | Softens, crumbles |
| Antibacterial | 99.5% | > 99.99% | Coatings only | None inherent |
| Demountable | Yes, repeatedly | Yes | Usually single use | No |
A2-S2,d0,t0, 0.3% water absorption, 99.5% antibacterial to JIS Z 2801, concealed triangular grid.
Open the range →NRC ≥ 0.90 to EN ISO 354, Class A to EN 13501-1, anti-mould Grade 0 to GJB 150.10A.
Open the range →Yes, and most hospital projects do exactly that: acoustic panels where speech privacy matters, GRP where cleaning is aggressive or humidity uncontrolled. Both are demountable, so the plane stays consistent down a corridor.
The glass-fibre acoustic range holds CE marking, with SGS reports and Korean fire certification. The GRP range ships with fire, antibacterial, hardness and chemical-resistance reports. If your clause names European marking, write it against the acoustic range.
MOQ is quoted per project, since it depends on panel mix and thickness. Samples go out with cut sections, so your team sees the build-up rather than the face alone.
