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 / The material
What this is, and what it changes in a Washington DC room
Timber slats on an acoustic backing. The slats are the finish and the rhythm, the backing does the absorbing. Used where the room has to look considered rather than treated.
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.
- Slats on felt backing The standard. Absorption comes from the backing behind the gaps, so the slat gap ratio is an acoustic decision, not only a visual one.
- Slats on a cavity Backing plus an air gap behind moves absorption lower, which matters in music rooms.
- Feature wall only Slats where they are seen, plain felt elsewhere, to hold the budget where it shows.
- What it will not do A tight slat pattern looks denser but absorbs less, because the open area is what lets sound reach the backing. If the visual you want and the RT target you need pull apart, we will tell you which one the pattern is serving.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for wooden slat panels are on the main product page. This page covers what that means for a project in Washington DC.
02 / The numbers
One specification sheet, the same in every market
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.
- MDFStandard. Dry interiors, general commercial
- FR MDFFire rated. Public buildings and anywhere the specification calls for a class
- HDHMRMoisture resistant. Humid climates and rooms that see damp

Consultants get the raw data, not a sales sheet. That is the whole of our side of the job, and it is set out under working with acoustic consultants.
03 / What drives the brief
The Washington DC conditions that change the answer
- 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.
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
Durability in Washington DC, before acoustics is discussed
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.
If the visual is fixed and the room still has to perform, that is a solvable problem and a conversation worth having early. See how we work with interior designers.
05 / Route to site
Getting it to Washington DC, with real dates
| 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 | Braced crates, slats supported along their length. Timber moves, so crates are kept flat and dry. |
| Lead time | Longer than felt. Confirmed against the pattern and substrate at quote stage. |
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 specification | 500 sq ft, about 46 sq m |
|---|
One unit covers 96 sq ft, so the minimum is a little over five units. Substrate, slat pattern, width and thickness can be mixed inside the same order.

What we will tell you that a reseller will not
-
The wrong product for the problem
A tight slat pattern looks denser but absorbs less, because the open area is what lets sound reach the backing. If the visual you want and the RT target you need pull apart, we will tell you which one the pattern is serving.
-
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.
Washington DC: questions we are actually asked
Are these wooden slat acoustic panels made in Washington DC?
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 do you look at first on a Washington DC enquiry?
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.
How does the Washington DC climate affect this product?
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.
How does an order actually travel to 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.
Where do wooden slat acoustic panels fail to help?
A tight slat pattern looks denser but absorbs less, because the open area is what lets sound reach the backing. If the visual you want and the RT target you need pull apart, we will tell you which one the pattern is serving.
How is the order packed and what is the minimum?
The same 500 sq ft minimum applies on export. Any specification, 500 sq ft, about 46 sq m. One unit covers 96 sq ft, so the minimum is a little over five units. Substrate, slat pattern, width and thickness can be mixed inside the same order. Braced crates, slats supported along their length. Timber moves, so crates are kept flat and dry.
