Acoustic panels in San Francisco
We manufacture acoustic panels at our own plant at Palwal in Haryana, India, and supply them into San Francisco. Made at our own plant in India and shipped into Oakland, across the bay, so the road leg to site is short.
- 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 make this ourselves and ship it to you. No local branch, no borrowed certifications, no dealer margin. One batch across the whole order, and an honest answer when the product is wrong for the problem.
01 / Start here
What this material is and where it earns its place in San Francisco
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 San Francisco is mostly victorian conversions, tech offices, apartments, studios, restaurants, 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 San Francisco.

02 / Specification sheet
One specification sheet, the same in every market
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. 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 San Francisco project, we supply to their specification and send the test reports rather than describing them. More on working with acoustic consultants.
03 / Local conditions
The San Francisco conditions that change the answer
- Timber Victorians
Light framed, over a century old, and divided into flats. Low frequency passes easily and footfall travels straight down.
- Depth costs real money
At local rates a wall growing into the room is a significant number. A dense thin membrane usually beats a thicker framed build-up on total cost.
- Designed to move
Seismic detailing requires junctions that stay flexible, so the acoustic layer must not stiffen across them.
- Oakland is close
A short road leg after the port keeps landed cost and timing 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.
Architects working in San Francisco 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 / Conditions
The San Francisco climate decides the material list
San Francisco 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
Getting it to San Francisco, with real dates
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Oakland, then a short road run across the bay |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Oakland |
| 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 Oakland, 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.
-
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.
-
Local approvals that nobody actually holds
We hold no San Francisco certification and we will not borrow one. The test data we publish is ours, and we will send the reports rather than describe them.

How it looks once it is installed
San Francisco: questions we are actually asked
Do you manufacture acoustic panels in San Francisco?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into San Francisco as the manufacturer rather than through a dealer. Made at our own plant in India and shipped into Oakland, across the bay, so the road leg to site is short. You buy at factory prices with one consistent batch across the order.
Why would a San Francisco build-up differ from anywhere else?
Light framed, over a century old, and divided into flats. Low frequency passes easily and footfall travels straight down. At local rates a wall growing into the room is a significant number. A dense thin membrane usually beats a thicker framed build-up on total cost. Those two things move the build-up far more than the panel figure does.
Is this the right material for San Francisco conditions?
San Francisco 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.
How quickly can material reach a site in San Francisco?
ships from: Palwal, Haryana, India, arrives at: Oakland, then a short road run across the bay, 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.
