Manufactured in India, supplied in Salem
Wood wool acoustic panels in Salem
We manufacture wood wool acoustic panels at our own plant at Palwal in Haryana, India, and supply them into Salem. Salem is steel and textiles in dry inland heat, so most of what we supply goes into working plant rather than interiors.

Manufacturer, not reseller. We hold no local approvals and will not imply we do. You get the price the factory quotes, material that matches across a large order, and advice that sometimes talks you out of a purchase.
01 / The material
What this material is and where it earns its place in Salem
Wood fibre bound into a rigid board with an open texture. Robust, paintable and used where the surface takes knocks, which is why it ends up in schools, sports halls and plant rooms.
Work reaching us from Salem is mostly steel and textile plant, workshops, offices, canteens, colleges, hospitals.
RC frame houses and apartments with hard floors, built for heat and humidity with open plan layouts that carry sound room to room.
- Direct fix Mechanically fixed to the soffit or wall. Durable and simple.
- On a cavity Mounted on battens with an air gap, which is where the low mid performance comes from.
- With a porous backing Board over mineral backing where the room needs more than the board alone gives.
- What it will not do At 20 mm it is a mid and high frequency absorber, not a bass solution, and painting it heavily will close the surface and reduce what it does. If a room needs low frequency control, depth or a cavity has to come from somewhere.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for wood wool panels are on the main product page. This page covers what that means for a project in Salem.
02 / Specification sheet
Published specification, identical wherever we ship it
We publish one data sheet for every market. If a supplier quotes you a different figure for the same product in a different city, one of the two numbers is wrong.
- Natural20 mm. Plant rooms, back of house, industrial
- Painted20 mm. Classrooms, halls, visible ceilings
| Panel size | 1200 x 600 mm |
|---|---|
| Thickness | 20 mm |
| Density | 400 kg per cubic metre |
| NRC | 0.30 |
| Test standards | ASTM C-423 and EN ISO 354 |
| Surface burning | Class A to ASTM E84 |
Where a consultant is already engaged on a Salem project, we supply to their specification and send the test reports rather than describing them. More on working with acoustic consultants.
03 / Local conditions
What the buildings in Salem do to the specification
- Plant noise is a mass problem
Mills, compressors and processing machinery are low frequency and structure-borne. Panels on a wall will not touch them.
- Hot buildings
PET felt does not sag, shed fibre or degrade at high temperature, which matters in a roof void above a hot process.
- Intelligibility on the floor
Large sheds where instructions and alarms have to be understood. Targeted absorption fixes that without touching the machines.
- Five days by road
A long run, confirmed before dispatch, with samples sent ahead.
- Assembly and performance rooms
Kalyana mandapams, temple halls and auditoria are very large hard volumes carrying amplified speech and music.
- School and campus buildings
Very large school and college campuses in concrete and tile, with auditoria and seminar halls used constantly.
Architects working in Salem usually need the build-up before the product. We will draw the section and mark what does the work. See how we support architects.
04 / Climate and durability
The Salem climate decides the material list
Salem is warm and humid through most of the year, with a long wet season, and that narrows the sensible material list before acoustics is even discussed.
Humidity is the deciding factor. PET felt does not absorb moisture, shed fibre or feed mould, which is why it outlasts fabric-wrapped mineral wool in this climate. Wood wool and timber need a ventilated cavity behind them.
The risk we design against here is mould, sagging fabric finishes and swelling in timber.
For a Salem interior where the finish leads, we will say plainly what each option costs you acoustically. See how we work with interior designers.
05 / Route to site
Getting it to Salem, with real dates
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | five days |
| Dispatch | 2 to 4 working days |
| To site | five days |
| Packing | Palletised flat, edge protected. Boards are rigid but the edges chip, so they travel protected. |
| Lead time | 4 to 7 working days for standard sizes. |
Standard items dispatch in 2 to 4 working days from our plant at Palwal. Grooved panels and custom colours take longer, and we say so before you order, not after.
By road from Palwal, roughly twenty three hundred kilometres, normally five days on a dedicated truck.
500 sq ft, about 46 sq m.
| Any finish | 500 sq ft, about 46 sq m |
|---|
A panel is 1200 x 600 mm, which is 0.72 sq m or about 7.75 sq ft, so the minimum is roughly 65 panels.
06 / Read this first
What we will tell you that a reseller will not
-
The wrong product for the problem
At 20 mm it is a mid and high frequency absorber, not a bass solution, and painting it heavily will close the surface and reduce what it does. If a room needs low frequency control, depth or a cavity has to come from somewhere.
-
Square footage quoted before the room is understood
Anyone can price a wall. Working out how much material the room actually needs usually reduces the order, which is why not everyone does it.

A claim of being local to Salem
We manufacture in India and supply here. We do not run an office in this city and we will not pretend to, because you would find out on the first site visit.
Salem: questions we are actually asked
Do you manufacture wood wool acoustic panels in Salem?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Salem as the manufacturer rather than through a dealer. Salem is steel and textiles in dry inland heat, so most of what we supply goes into working plant rather than interiors. You buy at factory prices with one consistent batch across the order.
What changes the specification on a Salem job?
Mills, compressors and processing machinery are low frequency and structure-borne. Panels on a wall will not touch them. PET felt does not sag, shed fibre or degrade at high temperature, which matters in a roof void above a hot process. Those two things move the build-up far more than the panel figure does.
Does Salem weather shorten the life of this material?
Salem is warm and humid through most of the year, with a long wet season. Humidity is the deciding factor. PET felt does not absorb moisture, shed fibre or feed mould, which is why it outlasts fabric-wrapped mineral wool in this climate. Wood wool and timber need a ventilated cavity behind them. The failure we design against here is mould, sagging fabric finishes and swelling in timber.
How does an order actually travel to Salem?
made at: Our own plant, Palwal, Haryana, reaches site in: five days, dispatch: 2 to 4 working days. Standard items dispatch in 2 to 4 working days from our plant at Palwal. Grooved panels and custom colours take longer, and we say so before you order, not after.
What will wood wool acoustic panels not do?
At 20 mm it is a mid and high frequency absorber, not a bass solution, and painting it heavily will close the surface and reduce what it does. If a room needs low frequency control, depth or a cavity has to come from somewhere.
What is the minimum order and how is it packed?
500 sq ft, about 46 sq m. Any finish, 500 sq ft, about 46 sq m. A panel is 1200 x 600 mm, which is 0.72 sq m or about 7.75 sq ft, so the minimum is roughly 65 panels. Palletised flat, edge protected. Boards are rigid but the edges chip, so they travel protected.
