PET felt acoustic panels in Chicago

We manufacture PET felt acoustic panels at our own plant at Palwal in Haryana, India, and supply them into Chicago. Made at our own plant in India, shipped into an East or Gulf coast port and railed inland, with that leg quoted separately so the dates are real.

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 product

What you are buying, and what it fixes in Chicago

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 Chicago is mostly two-flats and three-flats, high-rise apartments, offices, venues, schools, clinics.

American homes are timber frame with gypsum board on both faces, so a party wall or a basement ceiling has almost no mass. Adding a second leaf with a limp membrane between does more than any amount of surface treatment.

  • 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 Chicago.

02 / Data sheet

The numbers, and they do not move by city

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

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

03 / In this market

What decides the build-up in Chicago

  • Elevated rail past the window

    Trains at window height put noise in through the glazing, not through the wall. The facade is where the money should go first.

  • Brick outside, timber inside

    Two-flats and three-flats have solid masonry outside and timber floors between families. Footfall travels down and masonry does nothing about it.

  • Sealed against hard winters

    Buildings close up for months and mechanical systems run hard, so sound accumulates inside rather than escaping.

  • No port, so plan the inland leg

    Everything arrives at a coast and rails in. We quote the sea leg and the inland leg separately.

  • School and campus buildings

    Public school buildings run long corridors with hard floors and lay-in tile ceilings that were chosen for cost, not for speech. Classroom reverberation and corridor spill are the two complaints, and both respond to ceiling area rather than wall panels.

If you are specifying for a Chicago project, we can give you a section, a BOQ and the honest limits of each layer. See how we support architects.

04 / Climate and durability

The Chicago climate decides the material list

Chicago is mild summers and cold, wet winters, and that narrows the sensible material list before acoustics is even discussed.

Cold external walls and long heating seasons make condensation behind a lining the thing to design out. PET felt is unaffected by damp air.

The risk we design against here is condensation and cold bridging behind new 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.

05 / Route to site

What the route into Chicago actually looks like

Supply into Chicago
Ships fromPalwal, Haryana, India
Arrives atAn East or Gulf coast port, then rail and road inland
Dispatch4 to 7 working days
FreightSea, then rail inland
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. The sea leg from India is long, so plan the full door to door window into the programme. We give real dates, not optimistic ones.

Sea freight into an East or Gulf coast port, then rail and road to Chicago. 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 / Straight talk

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.

  • 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 Chicago

    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

Chicago: questions we are actually asked

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

No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Chicago as the manufacturer rather than through a dealer. Made at our own plant in India, shipped into an East or Gulf coast port and railed inland, with that leg quoted separately so the dates are real. You buy at factory prices with one consistent batch across the order.

What changes the specification on a Chicago job?

Trains at window height put noise in through the glazing, not through the wall. The facade is where the money should go first. Two-flats and three-flats have solid masonry outside and timber floors between families. Footfall travels down and masonry does nothing about it. Those two things move the build-up far more than the panel figure does.

Will this material last in the Chicago climate?

Chicago is mild summers and cold, wet winters. Cold external walls and long heating seasons make condensation behind a lining the thing to design out. PET felt is unaffected by damp air. The failure we design against here is condensation and cold bridging behind new linings.

What is the delivery time into Chicago?

ships from: Palwal, Haryana, India, arrives at: An East or Gulf coast port, then rail and road inland, dispatch: 4 to 7 working days. Standard items dispatch in 4 to 7 working days. The sea leg from India is long, so plan the full door to door window into the programme. We give real dates, not optimistic ones.

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.

What is the minimum order and how is it packed?

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.

Send a plan and a section, get a real build-up

A plan and a section is enough. We will come back with a build-up, a BOQ and a delivered date, and we will say so if what you are asking for will not work.
