Wood wool acoustic panels in Visakhapatnam
We manufacture wood wool acoustic panels at our own plant at Palwal in Haryana, India, and supply them into Visakhapatnam. Visakhapatnam is a port and a steel city on a cyclone coast, which means heavy industry and a climate that destroys the wrong material.

This comes from our own plant, not a trading desk. We do not have an office in your city and we will not invent one. What we can give you is factory pricing, consistent material and a technical answer before you commit.
01 / What it is
The material, and what it actually does on a Visakhapatnam job
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 Visakhapatnam is mostly steel and port industry, control rooms, offices, hospitals, colleges, hotels.
RC frame houses and apartments with hard floors, in towns where units share walls and slabs.
- 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 Visakhapatnam.
02 / Data sheet
Published specification, identical wherever we ship it
The specification below is the same everywhere we supply, because a specification that changed by city would not be a specification. What changes is which grade and build-up is the right buy, and that is what the rest of this page is about.
- Natural20 mm. Plant rooms, back of house, industrial
- Painted20 mm. Classrooms, halls, visible ceilings

Where a consultant is already engaged on a Visakhapatnam project, we supply to their specification and send the test reports rather than describing them. More on working with acoustic consultants.
03 / In this market
The Visakhapatnam conditions that change the answer
- Heavy industry, low frequency
Mills, blowers and compressors put energy into the structure. Mass, isolation and enclosure are the only things that address it.
- Control rooms run long shifts
Operators listening for alarms need a low background before anything else matters.
- Salt air and cyclone coast
PET felt does not absorb moisture, rot or corrode, which matters where mineral products fail within a couple of seasons.
- Four days by road
A long run, confirmed before dispatch, with samples sent ahead of the order.
- Assembly and performance rooms
Auditoriums, banquet halls and places of worship are large hard volumes in concrete and stone where speech falls apart long before anyone calls the room echoey.
- School and campus buildings
Large school and college campuses in concrete and tile, with halls carrying assembly and examination duty.
If you are specifying for a Visakhapatnam project, we can give you a section, a BOQ and the honest limits of each layer. See how we support architects.
04 / Durability
What the Visakhapatnam climate rules in and rules out
Visakhapatnam 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 Visakhapatnam interior where the finish leads, we will say plainly what each option costs you acoustically. See how we work with interior designers.
05 / Supply
How material reaches a Visakhapatnam site
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | four days |
| Dispatch | 2 to 4 working days |
| To site | four 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 eighteen hundred kilometres, normally four 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 / Worth knowing
Four honest warnings before you buy
-
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.
-
A number chased without a measurement
If nobody has measured the room or set a target, the specification is a guess with a decimal point in it. We will ask for the target before we quote the quantity.

Suppliers who imply a Visakhapatnam presence
Ask any supplier where the material is made and who carries the warranty. We make it at Palwal in Haryana and we say so on every page, including this one.
Visakhapatnam: questions we are actually asked
Where are the wood wool acoustic panels you supply to Visakhapatnam actually made?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Visakhapatnam as the manufacturer rather than through a dealer. Visakhapatnam is a port and a steel city on a cyclone coast, which means heavy industry and a climate that destroys the wrong material. You buy at factory prices with one consistent batch across the order.
Why would a Visakhapatnam build-up differ from anywhere else?
Mills, blowers and compressors put energy into the structure. Mass, isolation and enclosure are the only things that address it. Operators listening for alarms need a low background before anything else matters. Those two things move the build-up far more than the panel figure does.
How does the Visakhapatnam climate affect this product?
Visakhapatnam 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 Visakhapatnam?
made at: Our own plant, Palwal, Haryana, reaches site in: four 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.
When are wood wool acoustic panels the wrong purchase?
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.

We quote from drawings, not from a square foot rate. Send a plan and the section through the critical wall or ceiling and you will get something you can actually build from.
