PET felt acoustic panels in Port Blair
We manufacture PET felt acoustic panels at our own plant at Palwal in Haryana, India, and supply them into Port Blair. Port Blair is reached by ship from the mainland, so the sailing schedule governs the delivery date rather than our dispatch date does.

Manufacturer, not reseller. We hold no local approvals and will not imply we do. You get the price the factory quotes, material that matches across a large order, and advice that sometimes talks you out of a purchase.
01 / What it is
The product, described honestly, for a Port Blair 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 Port Blair is mostly hotels and guest houses, administrative buildings, hospitals, schools, dining spaces, offices.
RC frame and timber construction with hard floors, in a very humid island climate where moisture resistance decides the material.
- 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 Port Blair.
02 / Data sheet
One specification sheet, the same in every market
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 Port Blair project, we supply to their specification and send the test reports rather than describing them. More on working with acoustic consultants.

What we see driving Port Blair briefs
- The sailing sets the date
Scheduled vessels, not our dispatch, determine arrival. We work backwards from the sailing and tell you the real date.
- Get it right the first time
A replacement means waiting for the next sailing. We confirm the specification and send samples before anything ships.
- Salt air and heavy monsoon
PET felt does not absorb moisture, rot or corrode, which matters where almost everything else degrades quickly.
- Seismic islands
Buildings are designed to move, so a build-up must not stiffen across a movement joint.
- 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.
For a Port Blair practice, the useful thing is a detail you can put in a drawing set, not a brochure. See how we support architects.
04 / Conditions
Durability in Port Blair, before acoustics is discussed
Port Blair 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.
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 / Route to site
Getting it to Port Blair, with real dates
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | a ship leg after Chennai |
| Dispatch | 2 to 4 working days |
| To site | a ship leg after Chennai |
| 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 to Chennai or Kolkata, then by ship to the islands. The sailing is scheduled and we plan the whole journey around it.
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 / Straight talk
What we will tell you that a reseller will not
-
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 Port Blair 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.
Port Blair: questions we are actually asked
Are these PET felt acoustic panels made in Port Blair?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Port Blair as the manufacturer rather than through a dealer. Port Blair is reached by ship from the mainland, so the sailing schedule governs the delivery date rather than our dispatch date does. You buy at factory prices with one consistent batch across the order.
What changes the specification on a Port Blair job?
Scheduled vessels, not our dispatch, determine arrival. We work backwards from the sailing and tell you the real date. A replacement means waiting for the next sailing. We confirm the specification and send samples before anything ships. Those two things move the build-up far more than the panel figure does.
Does Port Blair weather shorten the life of this material?
Port Blair 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 Port Blair?
made at: Our own plant, Palwal, Haryana, reaches site in: a ship leg after Chennai, 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.
Where do PET felt acoustic panels fail to help?
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.
Is there a minimum order, and how does it arrive?
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.
