Manufactured in India, supplied in Seattle
Acoustic panels in Seattle
We manufacture acoustic panels at our own plant at Palwal in Haryana, India, and supply them into Seattle. Made at our own plant in India and shipped into Seattle or Tacoma, so the container lands at the city it is destined for rather than crossing the country first.
- Plain PET felt
- 9 to 24 mm, 1220 x 2440 mm standard, up to 2440 x 4270 mm, 1200 to 3600 GSM
- Printed felt
- 1800 x 900 mm, image printed into the felt rather than onto a facing
- Grooved panels
- Cut pattern in PET felt, adds visual rhythm without changing the absorber
- Test standard
- ASTM C423
- Lead time
- 4 to 7 working days standard
- Minimum order
- From 10 panels
- ASTM C423
- Made at our own plant, Palwal, Haryana, India
- One batch across the order, no blending between runs
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 / The material
What this material is and where it earns its place in Seattle
The full absorber range rather than one product: plain PET felt, printed felt, grooved panels and fabric finishes, chosen by how the room is used and how it has to look.
Work reaching us from Seattle is mostly mass timber offices, tech campuses, multifamily, studios, 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.
- Wall array Panels placed at first reflection points rather than spread evenly. Fewer panels, better result.
- Ceiling first In most rooms the ceiling is the largest untreated surface and the cheapest square metre of result.
- Mixed finish Plain felt where it is out of eye line, printed or grooved where it is seen.
- What it will not do Coverage is not the target, reverberation time is. Lining every surface wastes money and can leave a room sounding dead and unpleasant.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for our acoustic panel range are on the main product page. This page covers what that means for a project in Seattle.

02 / Data sheet
The numbers, and they do not move by city
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. General commercial
- EchoPro 181800 GSM. Rooms with a written RT target
- EchoMax 222200 GSM. High occupancy and high level spaces

| Test standard | ASTM C423 |
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 / Local conditions
The Seattle conditions that change the answer
- Mass timber is still light
Exposed timber looks solid and performs nothing like concrete at low frequency. It also cannot be covered, because the timber is the design, so the acoustic work has to happen where it will not be seen.
- Rain on the roof
Metal and membrane roofs over open volumes turn heavy rain into a noise source. It is worth designing for rather than discovering in the first storm.
- Campus open plans
Large tech floors with exposed structure and hard finishes carry speech a long way. The ceiling plane and screens have to do what the walls are not there to do.
- The port is right here
Containers land at Seattle or Tacoma, so there is no cross-country leg. That keeps the landed cost and the date both predictable.
- 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.
- The studio and content scene
Home and project studios go into basements and converted garages with equipment budgets far ahead of the building. The room leaks to the floor above long before it sounds wrong inside.
We would rather argue about the build-up at design stage than on site. See how we support architects.
04 / Durability
The Seattle climate decides the material list
Seattle 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.
For a Seattle interior where the finish leads, we will say plainly what each option costs you acoustically. See how we work with interior designers.
05 / Supply
Getting it to Seattle, with real dates
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Seattle or Tacoma, then a short road run to site |
| Dispatch | 4 to 7 working days |
| Freight | Sea into Seattle or Tacoma |
| Packing | Palletised flat and film wrapped. Printed panels interleaved and corner protected. |
| Lead time | 4 to 7 working days standard. Printed and grooved take longer. |
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 Seattle or Tacoma, 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.
| Trial order | 200 panels, 6,400 sq ft, mixed thickness, GSM and colour |
|---|---|
| Recommended | Full container |
A panel is 1220 x 2440 mm, which is 32 sq ft.

The things worth knowing before you place the order
-
The wrong product for the problem
Coverage is not the target, reverberation time is. Lining every surface wastes money and can leave a room sounding dead and unpleasant. We would rather calculate the area than sell the wall.
-
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 Seattle certification and we will not borrow one. The test data we publish is ours, and we will send the reports rather than describe them.

Seattle: questions we are actually asked
Is there a Seattle factory behind this product?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Seattle as the manufacturer rather than through a dealer. Made at our own plant in India and shipped into Seattle or Tacoma, so the container lands at the city it is destined for rather than crossing the country first. You buy at factory prices with one consistent batch across the order.
What changes the specification on a Seattle job?
Exposed timber looks solid and performs nothing like concrete at low frequency. It also cannot be covered, because the timber is the design, so the acoustic work has to happen where it will not be seen. Metal and membrane roofs over open volumes turn heavy rain into a noise source. It is worth designing for rather than discovering in the first storm. Those two things move the build-up far more than the panel figure does.
Does Seattle weather shorten the life of this material?
Seattle 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 Seattle site?
ships from: Palwal, Haryana, India, arrives at: Seattle or Tacoma, then a short road run to site, 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.
When are acoustic panels the wrong purchase?
Coverage is not the target, reverberation time is. Lining every surface wastes money and can leave a room sounding dead and unpleasant. We would rather calculate the area than sell the wall.
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. Trial order, 200 panels, 6,400 sq ft, mixed thickness, GSM and colour. Recommended, Full container. A panel is 1220 x 2440 mm, which is 32 sq ft. Palletised flat and film wrapped. Printed panels interleaved and corner protected.
