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 / The material

What you are buying, and what it fixes in Lakshadweep

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 Lakshadweep is mostly resort villas and guest rooms, administrative buildings, schools, clinics, dining spaces.

Compact RC frame and block construction with hard floors, on small islands in a salt laden humid climate.

  • 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 Lakshadweep.

02 / Data sheet

The published figures, unchanged by location

We publish one data sheet for every market. If a supplier quotes you a different figure for the same product in a different city, one of the two numbers is wrong.

  • 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 / Local conditions

What the buildings in Lakshadweep do to the specification

  • The last leg is by sea

    Vessel transfer means handling, spray and limited lifting. We wrap, brace and size pallets for that rather than for a loading dock.

  • Get it right the first time

    A wrong or damaged item cannot be replaced quickly. We confirm the specification and send samples before anything ships.

  • Salt air is relentless

    PET felt does not absorb moisture, rot or corrode. On a coral atoll that is not a preference, it is the only sensible choice.

  • Lightly built structures

    Island construction has little mass, so isolation between rooms is limited by the building and we say so rather than overselling.

  • 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.

Architects working in Lakshadweep usually need the build-up before the product. We will draw the section and mark what does the work. See how we support architects.

04 / Climate and durability

Why the climate in Lakshadweep changes the material, not the target

Lakshadweep 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.

For a Lakshadweep interior where the finish leads, we will say plainly what each option costs you acoustically. See how we work with interior designers.

05 / Route to site

Getting it to Lakshadweep, with real dates

Supply into Lakshadweep

Reaches site ina boat leg after Kochi
Dispatch2 to 4 working days
To sitea boat leg after Kochi
PackingPalletised flat and film wrapped, cut sheets interleaved. Packing list and weights issued with the quote.
Lead time4 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 Kochi, then by ship to the islands. The final leg is a vessel transfer and we pack for it.

From 10 panels for 9 mm EchoCore 15. Other grades and thicknesses carry their own minimum.

06 / Before you buy

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 Lakshadweep 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.

FAQ

Lakshadweep: questions we are actually asked

Where are the PET felt acoustic panels you supply to Lakshadweep actually made?

No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Lakshadweep as the manufacturer rather than through a dealer. Lakshadweep finishes its journey by ship. You buy at factory prices with one consistent batch across the order.

Why would a Lakshadweep build-up differ from anywhere else?

Vessel transfer means handling, spray and limited lifting. We wrap, brace and size pallets for that rather than for a loading dock. A wrong or damaged item cannot be replaced quickly. We confirm the specification and send samples before anything ships. Those two things move the build-up far more than the panel figure does.

Will this material last in the Lakshadweep climate?

Lakshadweep 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 quickly can material reach a site in Lakshadweep?

made at: Our own plant, Palwal, Haryana, reaches site in: a boat leg after Kochi, 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?

We quote from drawings, not from a square foot rate. Send a plan and the section through the critical wall or ceiling and you will get something you can actually build from.
