Manufactured in India, supplied in Kanpur
PET felt acoustic panels in Kanpur

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 product, described honestly, for a Kanpur brief
A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. It absorbs mid and high frequency energy and finishes as the visible surface, so it is both the acoustic layer and the finish.
Work reaching us from Kanpur is mostly leather and textile units, engineering workshops, offices, colleges, hospitals, banquet halls.
Independent houses and builder flats in brick and RC frame, often built floor by floor for different households, so the slab between them was never detailed as a separation.
- Direct to wall Panel bonded or mechanically fixed flat to the substrate. Simplest, and the weakest at low frequency.
- On a 25 to 50 mm air gap The same panel on battens. The air gap moves absorption down in frequency at no extra material cost, and is the cheapest improvement available.
- Over a porous backing Panel over mineral or PET backing where the room needs genuine low mid control.
- What it will not do It absorbs. It does not block.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for PET felt panels are on the main product page. This page covers what that means for a project in Kanpur.
02 / Specification
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.
- EchoCore 151500 GSM. Offices, classrooms, general commercial
- EchoPro 181800 GSM. Studios, auditoria, 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.
03 / On the ground
What the buildings in Kanpur do to the specification
- Machinery, long shifts
Continuous machine noise for whole shifts. Enclosure or barrier at the machine is the honest fix, not lining the hall.
- Industry beside housing
Units sit close to homes, so noise leaving the building matters as much as noise inside it. Two different treatments.
- Older building stock
Solid masonry with high ceilings, which holds sound and offers little in the way of a cavity to work with.
- Next day from the plant
A short run, so freight stays cheap and samples reach you quickly.
- School and campus buildings
Large government and private schools in concrete and tile with very large class sizes, and long open corridors that feed every classroom off them.
If you are specifying for a Kanpur project, we can give you a section, a BOQ and the honest limits of each layer. See how we support architects.
04 / Conditions
Durability in Kanpur, before acoustics is discussed
Kanpur 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.
For a Kanpur interior where the finish leads, we will say plainly what each option costs you acoustically. See how we work with interior designers.
05 / Supply
What the route into Kanpur actually looks like
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | a day |
| Dispatch | 2 to 4 working days |
| To site | a day |
| Packing | Palletised flat and film wrapped, cut sheets interleaved. Packing list and weights issued with the quote. |
| Lead time | 4 to 7 working days for standard colours and thicknesses. Grooved and custom colours take longer, and we say so before you order. |
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 five 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 |

| 24 mm, 3600 GSM | 50 panels, 1,600 sq ft |
A panel is 1220 x 2440 mm, which is 32 sq ft.
06 / Before you buy
Where this goes wrong, said plainly
-
The wrong product for the problem
It absorbs. It does not block. A PET panel on a shared wall will make the room sound better and will not stop the neighbour being heard. If the brief is stopping noise passing through a wall or floor, the answer is mass and decoupling, and we will say so before quoting.
-
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.
-
Local approvals that nobody actually holds
We hold no Kanpur certification and we will not borrow one. The test data we publish is ours, and we will send the reports rather than describe them.
Kanpur: questions we are actually asked
Do you manufacture PET felt acoustic panels in Kanpur?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Kanpur as the manufacturer rather than through a dealer. Kanpur is an old industrial city, and a lot of what we supply goes into working units rather than interiors. You buy at factory prices with one consistent batch across the order.
Why would a Kanpur build-up differ from anywhere else?
Continuous machine noise for whole shifts. Enclosure or barrier at the machine is the honest fix, not lining the hall. Units sit close to homes, so noise leaving the building matters as much as noise inside it. Two different treatments. Those two things move the build-up far more than the panel figure does.
Will this material last in the Kanpur climate?
Kanpur 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 Kanpur?
made at: Our own plant, Palwal, Haryana, reaches site in: a 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 will PET felt acoustic panels not do?
It absorbs. It does not block. A PET panel on a shared wall will make the room sound better and will not stop the neighbour being heard. If the brief is stopping noise passing through a wall or floor, the answer is mass and decoupling, and we will say so before quoting.
What is the minimum order and how is it packed?
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.
