PET felt acoustic panels in Dibrugarh

We manufacture PET felt acoustic panels at our own plant at Palwal in Haryana, India, and supply them into Dibrugarh. Dibrugarh runs on tea and on oil and gas, so the work is processing plant and the institutional buildings that serve those industries.

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 / Start here

What you are buying, and what it fixes in Dibrugarh

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 Dibrugarh is mostly tea processing units, energy sector offices, hospitals, colleges, hotels, assembly halls.

RC frame and timber construction with hard floors, built for very heavy rainfall and high humidity year round.

  • 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 Dibrugarh.

02 / Specification

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

03 / Local conditions

What decides the build-up in Dibrugarh

  • Processing machinery

    Driers, sorters and fans running continuously in humid buildings. Enclosure at the source is the reliable answer.

  • Very high humidity

    PET felt does not absorb moisture, shed fibre or feed mould, which matters in a climate where mineral products fail quickly.

  • A long supply route

    Five days by road, confirmed before dispatch, and packed for the journey rather than for a short transfer.

  • Seismic and flood prone

    Buildings are designed to move and often raised. A build-up must respect both rather than fight them.

  • School and campus buildings

    Schools and colleges are naturally ventilated with open corridors and large class sizes.

We would rather argue about the build-up at design stage than on site. See how we support architects.

04 / Conditions

The Dibrugarh climate decides the material list

Dibrugarh 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.

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.

How material reaches a Dibrugarh site

Reaches site infive days
Dispatch2 to 4 working days
To sitefive 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 twenty two hundred kilometres, normally five days on a dedicated truck.

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

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.

  • 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.

  • A claim of being local to Dibrugarh

    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

Dibrugarh: questions we are actually asked

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

No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Dibrugarh as the manufacturer rather than through a dealer. Dibrugarh runs on tea and on oil and gas, so the work is processing plant and the institutional buildings that serve those industries. You buy at factory prices with one consistent batch across the order.

What decides the specification for a Dibrugarh project?

Driers, sorters and fans running continuously in humid buildings. Enclosure at the source is the reliable answer. PET felt does not absorb moisture, shed fibre or feed mould, which matters in a climate where mineral products fail quickly. Those two things move the build-up far more than the panel figure does.

Will this material last in the Dibrugarh climate?

Dibrugarh 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 Dibrugarh?

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 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.

Is there a minimum order, and how does it arrive?
