- Test reports sent on request, not just quoted
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 / The material
What you are buying, and what it fixes in Washington DC
Open cell foam shapes for high frequency control, and BassBloc, a high density absorber built for the low mid range where ordinary foam does nothing.
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.
- Corner loading Low frequency energy collects in corners, so absorber in the corners does more than the same area spread across a wall.
- First reflection points Mirror trick placement on side walls and ceiling, which is a handful of panels rather than a lined room.
- Behind a fabric frame Where the room has to look finished, absorber inside a frame rather than foam on show.
- What it will not do Thin foam on a wall is the most over-sold product in this industry. It controls flutter and nothing below it.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for acoustic foam and bass traps are on the main product page. This page covers what that means for a project in Washington DC.
02 / Specification
The numbers, and they do not move by city
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.
- Foam wedge and pyramidLow density. Flutter and high frequency only
- BassBloc100 kg per cubic metre. Low mid absorption, control rooms, live rooms
| BassBloc size | 1800 x 900 mm |
|---|---|
| BassBloc thickness | 20 mm |
| BassBloc density | 100 kg per cubic metre |
| Effective range | 100 to 500 Hz |
| BassBloc NRC | 0.85 |
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.
- The housing stock
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.
- 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.
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 / 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 / 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 | Compressed and boxed for foam, palletised flat for BassBloc. |
| Lead time | 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.
Sea freight into Baltimore or Norfolk, then a short road run into the city. Air freight for samples and urgent quantities.
The same minimums apply on export.
| Acoustic foam | 200 sq ft, about 19 sq m |
|---|---|
| BassBloc | 300 sq ft, about 28 sq m |
| Bass traps | 10 pieces |
A BassBloc panel is 1800 x 900 mm, which is 1.62 sq m or about 17.4 sq ft, so the BassBloc minimum is roughly 17 panels.
06 / Straight talk
Four honest warnings before you buy
-
The wrong product for the problem
Thin foam on a wall is the most over-sold product in this industry. It controls flutter and nothing below it. If the complaint is boom, bass from a neighbour, or a room that sounds uneven at low frequency, foam is the wrong purchase and we will say so.
-
Coverage bought instead of a target
Lining every surface is a purchase, not a result. We would rather calculate the area against a reverberation target and sell you less of it.
-
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 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.
What should you not buy acoustic foam and BassBloc for?
Thin foam on a wall is the most over-sold product in this industry. It controls flutter and nothing below it. If the complaint is boom, bass from a neighbour, or a room that sounds uneven at low frequency, foam is the wrong purchase and we will say so.
Is there a minimum order, and how does it arrive?
The same minimums apply on export. Acoustic foam, 200 sq ft, about 19 sq m. BassBloc, 300 sq ft, about 28 sq m. Bass traps, 10 pieces. A BassBloc panel is 1800 x 900 mm, which is 1.62 sq m or about 17.4 sq ft, so the BassBloc minimum is roughly 17 panels. Compressed and boxed for foam, palletised flat for BassBloc.
