Manufactured in India, supplied in Denver
PET felt acoustic panels in Denver
We manufacture PET felt acoustic panels at our own plant at Palwal in Haryana, India, and supply them into Denver. Made at our own plant in India, shipped into Houston or the West Coast and trucked inland, with the road leg quoted separately so the programme runs on real dates.

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 you are buying, and what it fixes in Denver
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 Denver is mostly multifamily apartments, offices, breweries and taprooms, schools, clinics, home theatres.
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 Denver.
02 / Specification
The published figures, unchanged by location
These figures are published and they do not move. The thing worth arguing about is not the number on the sheet, it is which grade and which build-up suits the room you are treating.
- 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

What the buildings in Denver do to the specification
- Taprooms and hard rooms
Breweries and taprooms are concrete, steel and glass by design. They are loud by construction, not by accident, and the ceiling plane is usually the only place to fix it.
- Light frame multifamily at volume
Thousands of units built to the same separating detail. If the detail underperforms it underperforms everywhere, which makes it worth solving on the drawing.
- No port, so plan the road leg
Everything arrives at a coast and drives in. We quote the sea leg and the road leg separately so you can see where the time goes.
- Dry air, sealed buildings
Our PET felt does not shed fibre or degrade in dry conditions, and it holds its shape in rooms that stay closed and conditioned.
- 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.
Architects working in Denver usually need the build-up before the product. We will draw the section and mark what does the work. See how we support architects.
04 / Durability
The Denver climate decides the material list
Denver 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.
Designers get colour, pattern and CNC options with the absorption figure attached to each. See how we work with interior designers.
05 / Route to site
Getting it to Denver, with real dates
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Houston or the West Coast, then road inland |
| Dispatch | 4 to 7 working days |
| Freight | Sea, then road inland |
| Packing | Palletised flat and film wrapped, cut sheets interleaved. Packing list and weights issued with the quote. |
| Lead time | 4 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 Houston or the West Coast, then road inland to Denver. 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.
| 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.
06 / Before you buy
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.
-
Local approvals that nobody actually holds
We hold no Denver certification and we will not borrow one. The test data we publish is ours, and we will send the reports rather than describe them.
Denver: questions we are actually asked
Do you manufacture PET felt acoustic panels in Denver?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Denver as the manufacturer rather than through a dealer. Made at our own plant in India, shipped into Houston or the West Coast and trucked inland, with the road leg quoted separately so the programme runs on real dates. You buy at factory prices with one consistent batch across the order.
What changes the specification on a Denver job?
Thousands of units built to the same separating detail. If the detail underperforms it underperforms everywhere, which makes it worth solving on the drawing. Breweries and taprooms are concrete, steel and glass by design. They are loud by construction, not by accident, and the ceiling plane is usually the only place to fix it. Those two things move the build-up far more than the panel figure does.
How does the Denver climate affect this product?
Denver 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.
When would material land on a Denver site?
ships from: Palwal, Haryana, India, arrives at: Houston or the West Coast, then 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.
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.
What quantity do we have to order, and in what packaging?
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.
