Acoustic panels in Washington DC
We manufacture acoustic panels at our own plant at Palwal in Haryana, India, and supply them into Washington DC. Made at our own plant in India and shipped into Baltimore or Norfolk, then a short road run into the city, with the full transit window quoted openly.
- 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
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
The product, described honestly, for a Washington DC brief
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 Washington DC is mostly institutional and association offices, meeting and briefing rooms, hotels, 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 Washington DC.

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. General commercial
- EchoPro 181800 GSM. Rooms with a written RT target
- EchoMax 222200 GSM. High occupancy and high level spaces

Where a consultant is already engaged on a Washington DC 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 the buildings in Washington DC do to the specification
- Privacy is the actual requirement
The question here is whether a conversation can be understood outside the room, not whether the room sounds pleasant. That needs the partition, the door and the ceiling handled together.
- Wide floorplates, low buildings
The height limit pushes buildings outward, so floors are broad and deep. Sound travels a long way across an open plan with nothing to interrupt it.
- Historic fabric downtown
Plenty of stock is old and protected. The work has to be internal and shallow, which rules out most thick framed systems.
- Meeting rooms used constantly
Association and institutional offices are mostly meeting space. Every one of those rooms has the same two demands: clear inside, inaudible outside.
- 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.
For a Washington DC practice, the useful thing is a detail you can put in a drawing set, not a brochure. See how we support architects.
04 / Climate and durability
What the Washington DC climate rules in and rules out
Washington DC 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 / Supply
How material reaches a Washington DC site
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Baltimore or Norfolk, then road into the city |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Baltimore or Norfolk |
| 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 Baltimore or Norfolk, then a short road run into the city. 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.
-
Square footage quoted before the room is understood
Anyone can price a wall. Working out how much material the room actually needs usually reduces the order, which is why not everyone does it.
-
Suppliers who imply a Washington DC presence
Ask any supplier where the material is made and who carries the warranty. We make it at Palwal in Haryana and we say so on every page, including this one.

The product on finished jobs
Washington DC: questions we are actually asked
Where are the acoustic panels you supply to Washington DC actually made?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Washington DC as the manufacturer rather than through a dealer. Made at our own plant in India and shipped into Baltimore or Norfolk, then a short road run into the city, with the full transit window quoted openly. You buy at factory prices with one consistent batch across the order.
Why would a Washington DC build-up differ from anywhere else?
The question here is whether a conversation can be understood outside the room, not whether the room sounds pleasant. That needs the partition, the door and the ceiling handled together. The height limit pushes buildings outward, so floors are broad and deep. Sound travels a long way across an open plan with nothing to interrupt it. Those two things move the build-up far more than the panel figure does.
Does Washington DC weather shorten the life of this material?
Washington DC 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 Washington DC?
ships from: Palwal, Haryana, India, arrives at: Baltimore or Norfolk, then road into the city, 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 should you not buy acoustic panels for?
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.
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. 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.
