PET felt acoustic panels in Visakhapatnam
We manufacture PET felt acoustic panels at our own plant at Palwal in Haryana, India, and supply them into Visakhapatnam. Visakhapatnam is a port and a steel city on a cyclone coast, which means heavy industry and a climate that destroys the wrong material.

01 / What it is
The material, and what it actually does on a Visakhapatnam job
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 Visakhapatnam is mostly steel and port industry, control rooms, offices, hospitals, colleges, hotels.
RC frame houses and apartments with hard floors, in towns where units share walls and slabs.
- 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 Visakhapatnam.
02 / Specification
The published figures, unchanged by location
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

Where a consultant is already engaged on a Visakhapatnam project, we supply to their specification and send the test reports rather than describing them. More on working with acoustic consultants.
03 / In this market
What the buildings in Visakhapatnam do to the specification
- Heavy industry, low frequency
Mills, blowers and compressors put energy into the structure. Mass, isolation and enclosure are the only things that address it.
- Control rooms run long shifts
Operators listening for alarms need a low background before anything else matters.
- Salt air and cyclone coast
PET felt does not absorb moisture, rot or corrode, which matters where mineral products fail within a couple of seasons.
- Four days by road
A long run, confirmed before dispatch, with samples sent ahead of the order.
- School and campus buildings
Large school and college campuses in concrete and tile, with halls carrying assembly and examination duty.
If you are specifying for a Visakhapatnam project, we can give you a section, a BOQ and the honest limits of each layer. See how we support architects.
04 / Conditions
The Visakhapatnam climate decides the material list
Visakhapatnam 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.
Designers get colour, pattern and CNC options with the absorption figure attached to each. See how we work with interior designers.
05 / Supply
Getting it to Visakhapatnam, with real dates
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | four days |

| To site | four days |
| 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 eighteen hundred kilometres, normally four days on a dedicated truck.
From 10 panels for 9 mm EchoCore 15. Other grades and thicknesses carry their own minimum.

06 / Straight talk
The things worth knowing before you place the order
-
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.
-
A number chased without a measurement
If nobody has measured the room or set a target, the specification is a guess with a decimal point in it. We will ask for the target before we quote the quantity.

Suppliers who imply a Visakhapatnam 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.
Visakhapatnam: questions we are actually asked
Do you manufacture PET felt acoustic panels in Visakhapatnam?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Visakhapatnam as the manufacturer rather than through a dealer. Visakhapatnam is a port and a steel city on a cyclone coast, which means heavy industry and a climate that destroys the wrong material. You buy at factory prices with one consistent batch across the order.
What changes the specification on a Visakhapatnam job?
Mills, blowers and compressors put energy into the structure. Mass, isolation and enclosure are the only things that address it. Operators listening for alarms need a low background before anything else matters. Those two things move the build-up far more than the panel figure does.
Is this the right material for Visakhapatnam conditions?
Visakhapatnam 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.
How does an order actually travel to Visakhapatnam?
made at: Our own plant, Palwal, Haryana, reaches site in: four 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 PET felt acoustic panels for?
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 quantity do we have to order, and in what packaging?
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.
