PET acoustic felt wall panels in office interior

Manufactured in India, supplied in Vapi

PET felt acoustic panels in Vapi

We manufacture PET felt acoustic panels at our own plant at Palwal in Haryana, India, and supply them into Vapi. Vapi is an industrial belt, and almost everything we supply here goes into a working plant rather than an interior.

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 / The material

What this is, and what it changes in a Vapi 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 Vapi is mostly process and chemical plants, utility and pump rooms, control rooms, offices, worker areas, clinics.

RC frame apartments and bungalows with stone and tile floors, in dry dusty conditions where open products collect dust.

  • 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 Vapi.

02 / Specification 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 / What drives the brief

The Vapi conditions that change the answer

  • Corrosive, humid air

    PET felt does not absorb moisture, rot or feed mould, which matters in a coastal industrial climate.

  • Plant runs continuously

    Pumps, compressors and blowers do not stop, so the noise is constant rather than intermittent. Enclosure at the source is the only answer that holds.

  • Boundary noise matters

    Housing sits close to industry here. Containing sound inside the site is a separate design from making the control room usable.

  • Control rooms need a low floor

    Operators listening for alarms need background noise down before anything else matters.

  • School and campus buildings

    Large school and college campuses in concrete and tile, with assembly halls and auditoria in constant use.

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

04 / Durability

The Vapi climate decides the material list

Vapi is hot and dry for most of the year, with dust and high daytime surface temperatures, and that narrows the sensible material list before acoustics is even discussed.

Dust is the enemy of open-cell products. PET felt does not shed, does not hold dust in the way fabric-wrapped glass wool does, and wipes down. Timber needs a stable indoor RH or it moves.

The risk we design against here is dust ingress and thermal movement in long runs.

Interior designers tend to arrive with the look already decided. We will tell you which finish gets there without losing the acoustics. See how we work with interior designers.

05 / Supply

How material reaches a Vapi site

Supply into Vapi
Made atOur own plant, Palwal, Haryana
Reaches site inthree days
Dispatch2 to 4 working days
To sitethree days
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 twelve hundred kilometres, normally three days on a dedicated truck.

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

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.

  • A claim of being local to Vapi

    We manufacture in India and supply here. We do not run an office in this city and we will not pretend to, because you would find out on the first site visit.

FAQ

Vapi: questions we are actually asked

Do you manufacture PET felt acoustic panels in Vapi?

No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Vapi as the manufacturer rather than through a dealer. Vapi is an industrial belt, and almost everything we supply here goes into a working plant rather than an interior. You buy at factory prices with one consistent batch across the order.

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

Pumps, compressors and blowers do not stop, so the noise is constant rather than intermittent. Enclosure at the source is the only answer that holds. Housing sits close to industry here. Containing sound inside the site is a separate design from making the control room usable. Those two things move the build-up far more than the panel figure does.

How does the Vapi climate affect this product?

Vapi is hot and dry for most of the year, with dust and high daytime surface temperatures. Dust is the enemy of open-cell products. PET felt does not shed, does not hold dust in the way fabric-wrapped glass wool does, and wipes down. Timber needs a stable indoor RH or it moves. The failure we design against here is dust ingress and thermal movement in long runs.

When would material land on a Vapi site?

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

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.
