Manufactured in India, supplied in Dehradun
Acoustic panels in Dehradun
We manufacture acoustic panels at our own plant at Palwal in Haryana, India, and supply them into Dehradun. Dehradun is a school town.

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 / Start here
The material, and what it actually does on a Dehradun job
The full absorber range rather than one product: plain PET felt, printed felt, grooved panels and fabric finishes, chosen by how the room is used and how it has to look.
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.
- Wall array Panels placed at first reflection points rather than spread evenly. Fewer panels, better result.
- Ceiling first In most rooms the ceiling is the largest untreated surface and the cheapest square metre of result.
- Mixed finish Plain felt where it is out of eye line, printed or grooved where it is seen.
- What it will not do Coverage is not the target, reverberation time is. Lining every surface wastes money and can leave a room sounding dead and unpleasant.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for our acoustic panel range are on the main product page. This page covers what that means for a project in Dehradun.

02 / The numbers
Published specification, identical wherever we ship it
Nothing below changes by location. The decisions that do change are grade, thickness and how the material is mounted, and those are covered further down.
- EchoCore 151500 GSM. General commercial
- EchoPro 181800 GSM. Rooms with a written RT target
- EchoMax 222200 GSM. High occupancy and high level spaces

Consultants get the raw data, not a sales sheet. That is the whole of our side of the job, and it is set out under working with acoustic consultants.

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.
- 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.
- The studio and content scene
Very little purpose built studio work. Most demand is hotel entertainment space and small content rooms inside existing hillside buildings.
For a Dehradun practice, the useful thing is a detail you can put in a drawing set, not a brochure. See how we support architects.
04 / Climate
The Dehradun climate decides the material list
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.
If the visual is fixed and the room still has to perform, that is a solvable problem and a conversation worth having early. 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 and film wrapped. Printed panels interleaved and corner protected. |
| Lead time | 4 to 7 working days standard. Printed and grooved take longer. |
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.
From 10 panels for 9 mm EchoCore 15. Other grades and thicknesses carry their own minimum.
| 9 mm EchoCore 15, 1500 GSM | 10 panels, 320 sq ft |
|---|---|
| 9 mm EchoPro 18, 1800 GSM | 50 panels, 1,600 sq ft |
| 9 mm EchoMax 22, 2200 GSM | 100 panels, 3,200 sq ft |
| 12 mm, 2400 GSM | 30 panels, 960 sq ft |
| 18 mm, 3000 GSM | 50 panels, 1,600 sq ft |
| 24 mm, 3600 GSM | 50 panels, 1,600 sq ft |
A panel is 1220 x 2440 mm, which is 32 sq ft.
06 / Worth knowing
What we will tell you that a reseller will not
-
The wrong product for the problem
Coverage is not the target, reverberation time is. Lining every surface wastes money and can leave a room sounding dead and unpleasant. We would rather calculate the area than sell the wall.
-
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.

How it looks once it is installed
Dehradun: questions we are actually asked
Is there a Dehradun factory behind this product?
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 decides the specification for a Dehradun project?
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.
Is this the right material for Dehradun conditions?
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.
How quickly can material reach a site in 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.
What should you not buy acoustic panels for?
Coverage is not the target, reverberation time is. Lining every surface wastes money and can leave a room sounding dead and unpleasant. We would rather calculate the area than sell the wall.
How is the order packed and what is the minimum?
From 10 panels for 9 mm EchoCore 15. Other grades and thicknesses carry their own minimum. 9 mm EchoCore 15, 1500 GSM, 10 panels, 320 sq ft. 9 mm EchoPro 18, 1800 GSM, 50 panels, 1,600 sq ft. 9 mm EchoMax 22, 2200 GSM, 100 panels, 3,200 sq ft. 12 mm, 2400 GSM, 30 panels, 960 sq ft. 18 mm, 3000 GSM, 50 panels, 1,600 sq ft. 24 mm, 3600 GSM, 50 panels, 1,600 sq ft.
