Slatted acoustic panels vs. fabric-wrapped panels: an honest comparison
Both absorb sound. They differ on durability, cleaning, design and price. Where each one actually wins, including the cases where fabric is the better buy.
Both products are absorbers. Both are sold as "acoustic panels". They are not interchangeable, and the difference is not marketing — it decides how long the wall lasts and who has to maintain it.
How each one actually absorbs
Slatted (our range): MDF slats with open gaps, bonded to polyester fibre felt. Sound enters through the gaps, the felt converts movement into a small amount of heat. The slats are also a resonant face, which broadens the absorption band slightly compared with a plain porous panel.
Fabric-wrapped: a mineral fibre or glass fibre core inside a fabric sleeve, edge-stitched or with a frame. Sound passes straight through the fabric into the core, which is a very efficient porous absorber — usually more efficient per square metre than a slatted panel of similar thickness.
Head to head
| Slatted panel | Fabric-wrapped panel | |
| Absorption per m² | Good (NRC 0.75–0.85) | Better, especially in mid and high frequencies |
| Low frequency | Limited unless mounted on a cavity | Limited unless a thick core or a cavity is used |
| Impact resistance | High — it is board on a wall | Low — fabric tears, corners deform |
| Cleaning | Vacuum or dry cloth; PVC film wipes clean | Vacuum only; most fabrics cannot be washed |
| Dust and staining over time | Stable | Visible, especially light colours |
| Design | The pattern is the design; 35+ finishes | Colour only; the panel reads as a soft rectangle |
| Installation labour | Moderate — screws through slat gaps | Low — adhesive or impaling clips |
| Damage repair | Replace one panel | Replace the panel; re-upholstery rarely matches |
| Fire performance | B1 standard | Depends on fabric and core; check the certificate carefully |
| Cost per m² (similar absorption) | Higher | Lower |
Where fabric-wrapped genuinely wins
- Recording studios and critical listening rooms. You need broadband absorption and you are going to cover large areas. Fabric is cheaper per unit of absorption and the dead look is the point.
- Ceiling clouds and hanging absorbers. Slatted panels are heavy for a hanging element; fabric-wrapped is the normal choice.
- Rooms where the wall is not the design feature. A boardroom with a strong timber floor and a stone wall does not need more pattern on the walls.
- Tight budgets on a large area. If the brief is "fix the echo for the least money", fabric wins.
Where slats win
- Public and semi-public interiors. Corridors, lobbies, restaurants, schools. Fabric in a school corridor has a life expectancy measured in months.
- Anywhere the wall is seen. The panel is the finish, not an add-on. You do not need a separate decorative lining and a separate acoustic treatment.
- Hot, humid or dusty climates. This is most of the market we ship to. Fabric holds dust; PVC film wipes clean.
- Curves and columns. Our flexible panel wraps a 620 mm column in the same finish as the flat wall. Fabric-wrapped panels on a curve need a custom frame per radius.
The honest summary
If you are treating a studio or a room nobody will look at, buy fabric-wrapped. If the wall is visible, gets touched, gets dusty, or needs to survive a public building for ten years, buy slatted — and accept that you are paying for the finish as well as the absorption.
What we do not recommend is the common compromise: cheap thin fabric panels hidden behind a decorative timber screen. The screen blocks the high frequencies the panel was bought to absorb, and the client pays twice.
Mixing them is legitimate
On larger projects we often quote slatted panels on the visible walls and fabric-wrapped absorbers on the ceiling or the rear wall where nobody looks. That is not a compromise — it is the correct use of each product. Ask us and we will tell you which parts of your room suit which.
