Manufactured in India, supplied in Boston
Soundproofing materials in Boston
We manufacture soundproofing materials at our own plant at Palwal in Haryana, India, and supply them into Boston. 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.

- One batch across the order, no blending between runs
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 / The material
What this is, and what it changes in a Boston room
The blocking side of the range taken together: mass loaded vinyl, resilient layers, cavity absorption and the build-ups they belong in. This is the page for someone whose problem is noise getting through, not a room that sounds wrong.
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.
- Independent leaf A second wall that does not touch the first. Nothing else comes close for the money.
- Resilient bar Where a full independent leaf will not fit. Effective, and very easy to short circuit with one wrong screw.
- Floating floor Resilient layer and deck, to break impact energy before it reaches the structure.
- What it will not do Soundproofing fails at the gaps, not the materials. A service penetration, a back to back socket, or a door undercut will undo a correctly built wall.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for our soundproofing materials are on the main product page. This page covers what that means for a project in Boston.

02 / The numbers
Published specification, identical wherever we ship it
The specification below is the same everywhere we supply, because a specification that changed by city would not be a specification. What changes is which grade and build-up is the right buy, and that is what the rest of this page is about.
- Light retrofit2.5 mm membrane. Where depth is not available
- Standard partition4 mm membrane on an independent leaf. The common specification
- Heavy6 mm membrane and full decoupling. Plant, machine enclosure, low frequency

On a Boston job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.

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.
- Plant and HVAC
Packaged rooftop units and ducted forced air are standard, so noise arrives through the duct rather than through the wall. Lining the first three metres of duct and treating the return path is usually the whole job.
- 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.
Architects working in Boston usually need the build-up before the product. We will draw the section and mark what does the work. See how we support architects.
04 / Climate
Durability in Boston, before acoustics is discussed
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 / Getting it there
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 | Rolls on core tubes, boards palletised, fixings and tapes listed on the same packing list. |
| Lead time | 4 to 7 working days for stock items. |
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.
06 / Straight talk
Where this goes wrong, said plainly
-
The wrong product for the problem
Soundproofing fails at the gaps, not the materials. A service penetration, a back to back socket, or a door undercut will undo a correctly built wall. We would rather spend the conversation on the detail than on the product.
-
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 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 soundproofing materials 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 changes the specification on a Boston job?
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.
How does the Boston climate affect this product?
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.
How quickly can material reach a site in 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 soundproofing materials for?
Soundproofing fails at the gaps, not the materials. A service penetration, a back to back socket, or a door undercut will undo a correctly built wall. We would rather spend the conversation on the detail than on the product.
Is there a minimum order, and how does it arrive?
Minimum order is confirmed with the quote. Rolls on core tubes, boards palletised, fixings and tapes listed on the same packing list.
