PET felt acoustic panels in Indore

We manufacture PET felt acoustic panels at our own plant at Palwal in Haryana, India, and supply them into Indore. Indore is growing quickly and building new, which means the acoustics can still be designed rather than retrofitted.

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 / What it is

The product, described honestly, for a Indore 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 Indore is mostly colleges and schools, hospitals, offices, food processing units, auditoriums, hotels.

RC frame apartments and independent houses with stone and tile floors, in a dry climate with dusty summers.

  • 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 Indore.

02 / Specification sheet

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

Where a consultant is already engaged on a Indore project, we supply to their specification and send the test reports rather than describing them. More on working with acoustic consultants.

03 / Local conditions

What decides the build-up in Indore

  • New buildings, late decisions

    Concrete and tile put up quickly, with the acoustic problem discovered at handover. Early drawings are worth more than extra material later.

  • Food processing plant

    Continuous machinery and packing lines close to occupied areas. Enclosure at the source rather than lining the hall.

  • Teaching and assembly

    Large lecture rooms and halls where speech fails long before anyone calls the room echoey.

  • Two days by road

    A manageable run, so freight stays reasonable and samples arrive before the order is placed.

  • School and campus buildings

    Large school and college campuses in concrete and tile with halls used for assembly and examinations.

Architects working in Indore 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 / Conditions

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

Indore 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.

What the route into Indore actually looks like

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, roughly nine hundred kilometres, normally two days on a dedicated truck.

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

06 / Worth knowing

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.

  • 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.

  • Local approvals that nobody actually holds

    We hold no Indore certification and we will not borrow one. The test data we publish is ours, and we will send the reports rather than describe them.

FAQ

Indore: questions we are actually asked

Are these PET felt acoustic panels made in Indore?

No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Indore as the manufacturer rather than through a dealer. Indore is growing quickly and building new, which means the acoustics can still be designed rather than retrofitted. You buy at factory prices with one consistent batch across the order.

What changes the specification on a Indore job?

Concrete and tile put up quickly, with the acoustic problem discovered at handover. Early drawings are worth more than extra material later. Continuous machinery and packing lines close to occupied areas. Enclosure at the source rather than lining the hall. Those two things move the build-up far more than the panel figure does.

How does the Indore climate affect this product?

Indore 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 Indore?

made at: Our own plant, Palwal, Haryana, reaches site in: two 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?
