Manufactured in India, supplied in Patna
Wood wool acoustic panels in Patna
We manufacture wood wool acoustic panels at our own plant at Palwal in Haryana, India, and supply them into Patna. Patna is building institutional space quickly, and almost all of it involves large rooms where a lot of people need to hear one person.

We are the manufacturer. There is no local office and we do not claim approvals we do not hold. What you get is factory pricing, one consistent batch across the order, and a straight answer on what the material will and will not do.
01 / The product
What this is, and what it changes in a Patna room
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 Patna is mostly coaching institutes and colleges, hospitals, government buildings, auditoriums, offices, hotels.
RC frame with brick infill and hard floors, in buildings that sit close together on narrow lanes.
- 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 Patna.
02 / Specification sheet
The published figures, unchanged by location
These figures are published and they do not move. The thing worth arguing about is not the number on the sheet, it is which grade and which build-up suits the room you are treating.
- Natural20 mm. Plant rooms, back of house, industrial
- Painted20 mm. Classrooms, halls, visible ceilings

Where a consultant is already engaged on a Patna project, we supply to their specification and send the test reports rather than describing them. More on working with acoustic consultants.
03 / On the ground
What the buildings in Patna do to the specification
- Rooms built for listening
Coaching halls and lecture rooms pack people into hard spaces. Intelligibility fails long before anyone describes the room as echoing.
- New institutional build
Concrete and tile put up quickly, with acoustics discovered at handover. Early drawings are worth more than extra material later.
- Medical privacy
Consult and counselling rooms where conversations have to stay in the room. Partition and door before panel.
- Two days by road
A manageable run, so freight is reasonable and samples arrive before the order is placed.
- 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 government and private schools in concrete and tile with very large class sizes and open corridors.
For a Patna practice, the useful thing is a detail you can put in a drawing set, not a brochure. See how we support architects.
04 / Climate and durability
Why the climate in Patna changes the material, not the target
Patna is hot summers, mild winters and a distinct wet season, and that narrows the sensible material list before acoustics is even discussed.
PET felt handles the wet months without absorbing moisture or feeding mould. Timber and wood wool want a ventilated cavity and a stable indoor RH.
The risk we design against here is wet-season humidity behind linings.
Designers get colour, pattern and CNC options with the absorption figure attached to each. See how we work with interior designers.
05 / Route to site
How material reaches a Patna site
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | two days |
| Dispatch | 2 to 4 working days |
| To site | two 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 ten hundred kilometres, normally two 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 / Straight talk
The things worth knowing before you place the order
-
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.
-
Coverage bought instead of a target
Lining every surface is a purchase, not a result. We would rather calculate the area against a reverberation target and sell you less of it.

A claim of being local to Patna
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.
Patna: questions we are actually asked
Where are the wood wool acoustic panels you supply to Patna actually made?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Patna as the manufacturer rather than through a dealer. Patna is building institutional space quickly, and almost all of it involves large rooms where a lot of people need to hear one person. You buy at factory prices with one consistent batch across the order.
What decides the specification for a Patna project?
Coaching halls and lecture rooms pack people into hard spaces. Intelligibility fails long before anyone describes the room as echoing. Concrete and tile put up quickly, with acoustics discovered at handover. Early drawings are worth more than extra material later. Those two things move the build-up far more than the panel figure does.
Is this the right material for Patna conditions?
Patna is hot summers, mild winters and a distinct wet season. PET felt handles the wet months without absorbing moisture or feeding mould. Timber and wood wool want a ventilated cavity and a stable indoor RH. The failure we design against here is wet-season humidity behind linings.
What is the delivery time into Patna?
made at: Our own plant, Palwal, Haryana, reaches site in: two 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 should you not buy wood wool acoustic panels for?
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.
Is there a minimum order, and how does it arrive?
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.
Next step
Tell us the room, we will tell you the build-up
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.
