01 / The material
What this material is and where it earns its place in Washington DC
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 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.
- 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 Washington DC.
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.
- Natural20 mm. Plant rooms, back of house, industrial
- Painted20 mm. Classrooms, halls, visible ceilings
| Panel size | 1200 x 600 mm |

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.
- 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 Washington DC project, we can give you a section, a BOQ and the honest limits of each layer. See how we support architects.
04 / Climate
Why the climate in Washington DC changes the material, not the target
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 / Route to site
What the route into Washington DC actually looks like
| 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, 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 Baltimore or Norfolk, then a short road run into the city. 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
Four honest warnings before you buy
-
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.
-
Local approvals that nobody actually holds
We hold no Washington DC certification and we will not borrow one. The test data we publish is ours, and we will send the reports rather than describe them.
Washington DC: questions we are actually asked
Is there a Washington DC 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 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.
What decides the specification for a Washington DC project?
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.
Is this the right material for Washington DC conditions?
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.
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.
How is the order packed and what is the minimum?
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.
