PET acoustic felt wall panels in office interior

Manufactured in India, supplied in Salem

PET felt acoustic panels in Salem

We manufacture PET felt acoustic panels at our own plant at Palwal in Haryana, India, and supply them into Salem. Salem is steel and textiles in dry inland heat, so most of what we supply goes into working plant rather than interiors.

We are the manufacturer. There is no local office and we do not claim approvals we do not hold. What you get is factory pricing, one consistent batch across the order, and a straight answer on what the material will and will not do.

01 / Start here

What this is, and what it changes in a Salem room

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 Salem is mostly steel and textile plant, workshops, offices, canteens, colleges, hospitals.

RC frame houses and apartments with hard floors, built for heat and humidity with open plan layouts that carry sound room to room.

  • 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 Salem.

02 / The numbers

One specification sheet, the same in every market

Nothing below changes by location. The decisions that do change are grade, thickness and how the material is mounted, and those are covered further down.

  • 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

On a Salem job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.

03 / On the ground

What the buildings in Salem do to the specification

  • Plant noise is a mass problem

    Mills, compressors and processing machinery are low frequency and structure-borne. Panels on a wall will not touch them.

  • Hot buildings

    PET felt does not sag, shed fibre or degrade at high temperature, which matters in a roof void above a hot process.

  • Intelligibility on the floor

    Large sheds where instructions and alarms have to be understood. Targeted absorption fixes that without touching the machines.

  • Five days by road

    A long run, confirmed before dispatch, with samples sent ahead.

  • School and campus buildings

    Very large school and college campuses in concrete and tile, with auditoria and seminar halls used constantly.

For a Salem practice, the useful thing is a detail you can put in a drawing set, not a brochure. See how we support architects.

04 / Climate and durability

What the Salem climate rules in and rules out

Salem 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.

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 Salem 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

Salem: questions we are actually asked

Are these PET felt acoustic panels made in Salem?

No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Salem as the manufacturer rather than through a dealer. Salem is steel and textiles in dry inland heat, so most of what we supply goes into working plant rather than interiors. You buy at factory prices with one consistent batch across the order.

What decides the specification for a Salem project?

Mills, compressors and processing machinery are low frequency and structure-borne. Panels on a wall will not touch them. PET felt does not sag, shed fibre or degrade at high temperature, which matters in a roof void above a hot process. Those two things move the build-up far more than the panel figure does.

Will this material last in the Salem climate?

Salem 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.

When would material land on a Salem site?

made at: Our own plant, Palwal, Haryana, reaches site in: five 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 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.
