Mineral Fiber Clouds - Mineral Fiber Ceiling Tiles
Quick summary: Mineral Fiber Clouds are free hanging mineral fiber ceiling tiles installed as floating islands instead of a full wall to wall grid. They give architects, interior designers and facility heads a way to add sound absorption, fire safety and a design statement to offices, hospitals, schools, airports and retail spaces without covering the entire slab. Use them where you want acoustic control, exposed services above, and a modern look in one product.
What Is a Mineral Fiber Cloud?
A Mineral Fiber Cloud is a mineral fiber ceiling panel suspended in individual sections, in rectangular, square or curved shapes, rather than as a continuous grid ceiling. In plain terms, it is a mineral fiber ceiling tile that hangs like an “island” below the structural slab, absorbing sound while leaving the services, ducting and slab visible around it. Facility planners specify clouds when they need acoustic ceiling tiles for open plan offices, auditoriums, cafeterias and reception areas that also want an exposed ceiling aesthetic
Why Ecotone Mineral Fiber Clouds?
Ecotone’s Mineral Fiber Clouds are built on the same mineral wool core used in our standard mineral fiber ceiling panels, so the same NRC, fire and humidity performance you expect from full mineral fiber ceilings carries over to a floating format. This range is written for architects, MEP consultants, turnkey contractors and facility managers working on commercial ceiling solutions across corporate offices, hospitals, hotels, airports, schools and retail chains in India, wherever a project brief calls for acoustic mineral fiber ceiling tiles with a distinct, branded ceiling design rather than a flat, edge to edge grid.

Installation Process
| Step | Action |
|---|---|
| 1 | Survey slab height, services and hanging points |
| 2 | Mark cloud layout and suspension grid points |
| 3 | Fix perimeter drop rods and cloud frame |
| 4 | Install drop ceiling grid systems for each cloud |
| 5 | Lay in mineral fiber ceiling panels on the frame |
| 6 | Level and align each cloud unit visually |
| 7 | Inspect fissures, edges and final finish. |
Why NRC and CAC Actually Matter on Site
| Acoustic Design Factor | Practical Guidance |
|---|---|
| NRC & CAC Ratings | NRC and CAC should not be treated only as numbers on a specification sheet. Real-world acoustic performance also depends on how the ceiling system is applied. |
| Coverage Percentage | Coverage percentage is a major project-design consideration. A Mineral Fiber Cloud with NRC 0.85 covering only 30% of the ceiling should not be assumed to perform like a full mineral fiber ceiling using material with the same NRC. |
| Open Offices | 40–60% visual coverage is typically recommended based on project conditions and measured reverberation time. |
| Auditoriums & Call Centres | Coverage may extend up to 70%, depending on measured reverberation time and the required acoustic performance. |
| NRC | Noise Reduction Coefficient indicates how effectively a material absorbs sound. NRC is determined using ASTM C423. |
| High NRC Performance | An NRC of 0.85 or higher represents strong sound-absorption performance for an acoustic ceiling product. |
| CAC | Ceiling Attenuation Class describes how effectively a ceiling system reduces sound transmission between adjoining enclosed rooms sharing a common ceiling plenum. CAC is tested using ASTM E1414. |
| Design Principle | Do not select a ceiling system from catalogue NRC alone. Consider the tile rating, coverage percentage, room geometry, application and measured reverberation time together. |

FAQs| Acoustic Mineral Fiber Clouds
1. What is a mineral fiber cloud ceiling?
A free hanging mineral fiber ceiling panel installed as an island, not a full grid.
2. Are mineral fiber ceiling tiles better than fiberglass ceiling tiles?
Mineral fiber offers higher density, better fire rating; fiberglass ceilings are lighter and cheaper.
3. Do mineral fiber ceiling tiles sag in humidity?
Standard tiles can; humidity resistant, sag resistant ceiling tiles are rated for high RH sites.
4. What NRC rating is good for an open office?
NRC 0.70 or higher is generally recommended for acoustic ceiling tiles in offices.
5. Are mineral fiber ceiling panels fire safe?
Yes, Class A fire rated ceiling tiles are non-combustible and meet building fire codes.
6. Can mineral fiber ceiling tiles be painted after installation?
Yes, but field painting can reduce NRC by filling the tile's absorptive surface pores.
7. What is the standard size of mineral fiber ceiling tiles?
Common sizes are 600Ă—600 mm and 600Ă—1200 mm, fitting standard drop ceiling grid systems.
8. Do mineral fiber ceiling tiles contain asbestos?
No, modern mineral fiber ceilings use mineral wool, not asbestos, per current manufacturing standards.
9. How long do mineral fiber ceiling tiles last?
With proper humidity control, mineral fiber ceiling installations typically last 15 to 25 years.
10. Can mineral fiber clouds be custom shaped?
Yes, custom mineral fiber ceilings support curved, rectangular or brand-specific cloud designs.
