Wood wool acoustic panels in Trivandrum
We manufacture wood wool acoustic panels at our own plant at Palwal in Haryana, India, and supply them into Trivandrum. Trivandrum is government and technology in a humid coastal climate, and it is the furthest point in the country from our plant.

01 / Start here
What this material is and where it earns its place in Trivandrum
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 Trivandrum is mostly government and institutional buildings, technology park offices, hospitals, colleges, hotels, auditoriums.
Independent houses with high ceilings, tile floors and open plan layouts built for heat and very heavy monsoon, which rules out anything that absorbs moisture.
- 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 Trivandrum.
02 / Specification sheet
The numbers, and they do not move by city
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.

On a Trivandrum job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.
03 / Local conditions
The Trivandrum conditions that change the answer
- Humidity decides the material
PET felt does not absorb moisture, shed fibre or feed mould. On this coast that is the whole selection argument.
- Our longest domestic run
Six days by road. We confirm dates before dispatch and send samples ahead so nothing is decided at the last moment.
- Technology park floors
Open plans with glass and hard flooring that carry every call across the room.
- Institutional assembly spaces
Large halls in concrete where speech stops being intelligible well before the room sounds wrong.
- Assembly and performance rooms
Auditoria, church buildings and community halls are large hard volumes carrying amplified speech and music.
- School and campus buildings
Schools and colleges are naturally ventilated with open corridors, so absorption alone will not fix intelligibility.
We would rather argue about the build-up at design stage than on site. See how we support architects.
04 / Durability
What the Trivandrum climate rules in and rules out
Trivandrum 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 Trivandrum interior where the finish leads, we will say plainly what each option costs you acoustically. See how we work with interior designers.
05 / Getting it there
What the route into Trivandrum actually looks like
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | six days |
| Dispatch | 2 to 4 working days |
| To site | six 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 six hundred kilometres, normally six days on a dedicated truck. It is the longest domestic run we operate.
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.

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.
-
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.

Suppliers who imply a Trivandrum 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.
Trivandrum: questions we are actually asked
Where are the wood wool acoustic panels you supply to Trivandrum actually made?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Trivandrum as the manufacturer rather than through a dealer. Trivandrum is government and technology in a humid coastal climate, and it is the furthest point in the country from our plant. You buy at factory prices with one consistent batch across the order.
What do you look at first on a Trivandrum enquiry?
Six days by road. We confirm dates before dispatch and send samples ahead so nothing is decided at the last moment. PET felt does not absorb moisture, shed fibre or feed mould. On this coast that is the whole selection argument. Those two things move the build-up far more than the panel figure does.
Will this material last in the Trivandrum climate?
Trivandrum 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.
When would material land on a Trivandrum site?
made at: Our own plant, Palwal, Haryana, reaches site in: six 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.
What quantity do we have to order, and in what packaging?
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.
