01 / The product
What you are buying, and what it fixes in Dehradun
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 Dehradun is mostly boarding schools and colleges, assembly halls, dormitories, hotels, hospitals, offices.
RC frame houses and hotels built on slopes, with hard floors and cold external walls in the hill towns.
- 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 Dehradun.
02 / Data sheet
Published specification, identical wherever we ship it
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

On a Dehradun job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.
03 / On the ground
The Dehradun conditions that change the answer
- Classrooms defeat the teacher
Hard floors, high ceilings and hard plaster mean a teacher raises their voice all day. Absorption on the ceiling recovers most of it.
- Halls used for everything
Assembly, examinations, performances and sport in one room. The design has to work for speech first and music second.
- Dormitories
Children sleeping next to corridors and each other. Partition and door detailing does more than anything applied inside the room.
- Next day from the plant
A short run, so freight stays low and samples arrive before the order.
- Assembly and performance rooms
Hotel banquet rooms, auditoria and temple halls are hard volumes carrying amplified speech and music.
- School and campus buildings
Classrooms are concrete and tile with bare walls and high ceilings, and class sizes push levels up. Corridors act as reverberation chambers that feed every room off them.
If you are specifying for a Dehradun project, we can give you a section, a BOQ and the honest limits of each layer. See how we support architects.
04 / Climate and durability
Durability in Dehradun, before acoustics is discussed
Dehradun 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 / Logistics
Getting it to Dehradun, with real dates
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | next day |
| Dispatch | 2 to 4 working days |
| To site | next day |
| 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 three hundred kilometres, normally next day 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
Where this goes wrong, said plainly
-
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.

Suppliers who imply a Dehradun 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.
Dehradun: questions we are actually asked
Do you manufacture wood wool acoustic panels in Dehradun?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Dehradun as the manufacturer rather than through a dealer. Dehradun is a school town. You buy at factory prices with one consistent batch across the order.
What do you look at first on a Dehradun enquiry?
Hard floors, high ceilings and hard plaster mean a teacher raises their voice all day. Absorption on the ceiling recovers most of it. Assembly, examinations, performances and sport in one room. The design has to work for speech first and music second. Those two things move the build-up far more than the panel figure does.
How does the Dehradun climate affect this product?
Dehradun 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 Dehradun?
made at: Our own plant, Palwal, Haryana, reaches site in: next day, 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.
How is the order packed and what is the minimum?
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.
