PET acoustic felt wall panels in office interior

Manufactured in India, supplied in Belgium

PET felt acoustic panels in Belgium

We manufacture PET felt acoustic panels at our own plant at Palwal in Haryana, India, and supply them into Belgium. Made at our own plant in India and shipped into Antwerp, one of the shortest port to site runs anywhere in Europe, which shows up directly in the landed cost.

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 Belgium 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 Belgium is mostly terraced housing, institutional and corporate offices, schools, clinics, restaurants, studios.

Narrow terraced houses sharing party walls, with timber upper floors and concrete below. Apartment stock is concrete with hard finishes.

  • 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 Belgium.

02 / Specification sheet

Published specification, identical wherever we ship it

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

If a consultant has set the target, we will quote against their figures rather than ours, and stay out of the scope they own. More on working with acoustic consultants.

03 / What drives the brief

The Belgium conditions that change the answer

  • Antwerp is the advantage

    The port is close to almost everywhere in the country, so the inland leg barely registers. That is the practical reason a factory in India competes well here.

  • Terraced brick, shared on both sides

    Most housing shares a party wall left and right. Speech and impact noise move sideways, which is a mass and decoupling job rather than a treatment job.

  • Institutional meeting spaces

    Offices built for meetings in several languages need speech privacy and clean intelligibility at the same time, which pulls the design in two directions unless the ceiling is handled properly.

  • Renovation, not new build

    The structure usually stays. Build-ups have to fit the depth and finishes already there, so shallow and effective beats thick and theoretically better.

  • School and campus buildings

    School buildings are hard surfaced with long corridors, and refectories are consistently the loudest rooms.

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

04 / Climate

What the Belgium climate rules in and rules out

Belgium is cool and damp, with long heating seasons and cold external walls, and that narrows the sensible material list before acoustics is even discussed.

Cold wall build-ups and long heating seasons mean interstitial condensation is a real risk behind any lining. PET felt is unaffected by damp air and will not feed mould where a fabric-faced mineral product would.

The risk we design against here is condensation behind linings in older, poorly insulated stock.

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 Belgium site

Supply into Belgium
Ships fromPalwal, Haryana, India
Arrives atAntwerp, then a short road run to site
Dispatch4 to 7 working days
FreightSea via Antwerp
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 4 to 7 working days. Grooved panels and custom colours take longer, and we say so before you order, not after.

Sea freight into Antwerp, then a short road run to site. Air freight for samples and urgent quantities.

200 panels for a trial order, in any mix of thickness, GSM and colour. Beyond a trial we would rather quote a container load, because the price per panel and the freight per panel both fall sharply and a part load pays for space it does not use.

Minimum order, pet felt acoustic panels
Trial order200 panels, 6,400 sq ft, mixed thickness, GSM and colour
RecommendedFull container, for the best price per panel and the lowest freight per panel

A panel is 1220 x 2440 mm, which is 32 sq ft.

06 / Worth knowing

Four honest warnings before you buy

  • 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 Belgium

    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

Belgium: questions we are actually asked

Are these PET felt acoustic panels made in Belgium?

No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Belgium as the manufacturer rather than through a dealer. Made at our own plant in India and shipped into Antwerp, one of the shortest port to site runs anywhere in Europe, which shows up directly in the landed cost. You buy at factory prices with one consistent batch across the order.

What changes the specification on a Belgium job?

The port is close to almost everywhere in the country, so the inland leg barely registers. That is the practical reason a factory in India competes well here. Most housing shares a party wall left and right. Speech and impact noise move sideways, which is a mass and decoupling job rather than a treatment job. Those two things move the build-up far more than the panel figure does.

How does the Belgium climate affect this product?

Belgium is cool and damp, with long heating seasons and cold external walls. Cold wall build-ups and long heating seasons mean interstitial condensation is a real risk behind any lining. PET felt is unaffected by damp air and will not feed mould where a fabric-faced mineral product would. The failure we design against here is condensation behind linings in older, poorly insulated stock.

When would material land on a Belgium site?

ships from: Palwal, Haryana, India, arrives at: Antwerp, then a short road run to site, dispatch: 4 to 7 working days. Standard items dispatch in 4 to 7 working days. 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.

How is the order packed and what is the minimum?

200 panels for a trial order, in any mix of thickness, GSM and colour. Beyond a trial we would rather quote a container load, because the price per panel and the freight per panel both fall sharply and a part load pays for space it does not use. Trial order, 200 panels, 6,400 sq ft, mixed thickness, GSM and colour. Recommended, Full container, for the best price per panel and the lowest freight per panel. A panel is 1220 x 2440 mm, which is 32 sq ft. Palletised flat and film wrapped, cut sheets interleaved. Packing list and weights issued with the quote.
