Manufactured in India, supplied in Seattle
Wood wool acoustic panels in Seattle
We manufacture wood wool 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.

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 / What it is
The product, described honestly, for a Seattle brief
Wood fibre bound into a rigid board with an open texture. Robust, paintable and used where the surface takes knocks, which is why it ends up in schools, sports halls and plant rooms.
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.
- Direct fix Mechanically fixed to the soffit or wall. Durable and simple.
- On a cavity Mounted on battens with an air gap, which is where the low mid performance comes from.
- With a porous backing Board over mineral backing where the room needs more than the board alone gives.
- What it will not do At 20 mm it is a mid and high frequency absorber, not a bass solution, and painting it heavily will close the surface and reduce what it does. If a room needs low frequency control, depth or a cavity has to come from somewhere.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for wood wool panels are on the main product page. This page covers what that means for a project in Seattle.
02 / Data sheet
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.
- Natural20 mm. Plant rooms, back of house, industrial
- Painted20 mm. Classrooms, halls, visible ceilings

On a Seattle job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.
03 / Local conditions
What the buildings in Seattle do to the specification
- 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.
- Assembly and performance rooms
Churches, school gyms and multipurpose halls double as performance spaces, which means a room designed for neither speech nor music has to carry both.
- 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 Seattle project, we can give you a section, a BOQ and the honest limits of each layer. See how we support architects.
04 / Climate
Durability in Seattle, before acoustics is discussed
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.
Designers get colour, pattern and CNC options with the absorption figure attached to each. See how we work with interior designers.
05 / Supply
What the route into Seattle actually looks like
| 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, edge protected. Boards are rigid but the edges chip, so they travel protected. |
| Lead time | 4 to 7 working days for standard sizes. |
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.
The same 500 sq ft minimum applies on export.
| Any finish | 500 sq ft, about 46 sq m |

A panel is 1200 x 600 mm, which is 0.72 sq m or about 7.75 sq ft, so the minimum is roughly 65 panels.
06 / Before you buy
Where this goes wrong, said plainly
-
The wrong product for the problem
At 20 mm it is a mid and high frequency absorber, not a bass solution, and painting it heavily will close the surface and reduce what it does. If a room needs low frequency control, depth or a cavity has to come from somewhere.
-
A number chased without a measurement
If nobody has measured the room or set a target, the specification is a guess with a decimal point in it. We will ask for the target before we quote the quantity.
-
A claim of being local to Seattle
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.
Seattle: questions we are actually asked
Where are the wood wool acoustic panels you supply to Seattle actually made?
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.
Why would a Seattle build-up differ from anywhere else?
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.
How does the Seattle climate affect this product?
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.
How quickly can material reach a site in Seattle?
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 wood wool acoustic panels the wrong purchase?
At 20 mm it is a mid and high frequency absorber, not a bass solution, and painting it heavily will close the surface and reduce what it does. If a room needs low frequency control, depth or a cavity has to come from somewhere.
Is there a minimum order, and how does it arrive?
The same 500 sq ft minimum applies on export. Any finish, 500 sq ft, about 46 sq m. A panel is 1200 x 600 mm, which is 0.72 sq m or about 7.75 sq ft, so the minimum is roughly 65 panels. Palletised flat, edge protected. Boards are rigid but the edges chip, so they travel protected.
