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 / What it is
The material, and what it actually does on a Boston job
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 Boston is mostly universities and labs, teaching hospitals, offices, triple-decker housing, studios, schools.
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 Boston.
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.
- 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 |
Where a consultant is already engaged on a Boston project, we supply to their specification and send the test reports rather than describing them. More on working with acoustic consultants.
03 / On the ground
What the buildings in Boston do to the specification
- Institutions specify properly
University and hospital work arrives with a consultant and a written target. Send us the specification and we will say where our material sits against it, in writing.
- Labs and equipment rooms
Fume hoods, chillers and equipment run constantly next to rooms where people have to concentrate. That is a plant isolation problem before it is a room treatment problem.
- Old brick and triple-deckers
Boston housing stock is old, wooden inside and stacked. Floors between units pass footfall easily, and a resilient layer under the finish is what fixes it.
- Sealed against hard winters
Buildings close up for months and mechanical systems run hard. Noise stops escaping and starts accumulating inside.
- 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.
We would rather argue about the build-up at design stage than on site. See how we support architects.
04 / Climate and durability
Why the climate in Boston changes the material, not the target
Boston 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 Boston actually looks like
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Boston or a nearby East Coast port, then road to site |
| Dispatch | 4 to 7 working days |
| Freight | Sea into the East Coast |
| 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 Boston or a nearby East Coast port, then road to site. Air freight for samples, approvals 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 / Read this first
Where this goes wrong, said plainly
-
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.
-
Suppliers who imply a Boston 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.

Boston: questions we are actually asked
Do you manufacture acoustic foam and BassBloc in Boston?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Boston as the manufacturer rather than through a dealer. Made at our own plant in India and shipped into Boston or a nearby East Coast port, then road to site, 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 Boston enquiry?
University and hospital work arrives with a consultant and a written target. Send us the specification and we will say where our material sits against it, in writing. Fume hoods, chillers and equipment run constantly next to rooms where people have to concentrate. That is a plant isolation problem before it is a room treatment problem. Those two things move the build-up far more than the panel figure does.
Will this material last in the Boston climate?
Boston 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 Boston?
ships from: Palwal, Haryana, India, arrives at: Boston or a nearby East Coast port, then road 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.
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.
What quantity do we have to order, and in what packaging?
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.
