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
A limp, high density sheet that adds mass to a partition, floor or duct without adding depth. It is the barrier product, not an absorber, and it is the right answer when the problem is noise passing through a structure.
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.
- Wall, decoupled Independent stud, membrane between the boards, cavity absorption, two boards. The membrane is one part of a system, never the whole answer.
- Floor, floating Membrane under a resilient layer and a floating deck, so impact energy is broken before it reaches the slab.
- Duct and plant wrap Membrane wrapped over the duct with a decoupling layer beneath, sealed at every lap.
- What it will not do Mass fixed hard to an existing wall gives far less than the same mass on an independent leaf. If we are told the wall cannot be thickened, we will say what the membrane will and will not achieve rather than quote the laboratory figure and let the site find out.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for SoundBlanket MLV are on the main product page. This page covers what that means for a project in Boston.
02 / Specification
The numbers, and they do not move by city
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.
- 2.5 mmSTC 30, 5.25 kg per sq m. Ducts, light partitions, retrofit where depth is tight
- 4 mmSTC 34, 8.4 kg per sq m. Party walls, floors, plant rooms, the common specification
- 6 mm12.6 kg per sq m. Machine enclosures and low frequency problems

What decides the build-up in Boston
- 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.
If you are specifying for a Boston project, we can give you a section, a BOQ and the honest limits of each layer. See how we support architects.
04 / 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
Getting it to Boston, with real dates
| 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, wrapped and end capped, 5 x 1.2 m. Weights on the packing list, because a full roll is heavy and site access matters. |
| Lead time | 4 to 7 working days. Full container quantities scheduled against the vessel. |
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 as on domestic orders.
| 2.5 mm and 4 mm | 10 rolls, 60 sq m |
|---|---|
| 6 mm and other thicknesses | 10 tonnes per thickness |
A SoundBlanket roll is 5 x 1.2 m, which is 6 sq m. At 2100 kg per cubic metre a roll weighs about 31.5 kg at 2.5 mm and about 50.4 kg at 4 mm, so a 10 roll minimum is 60 sq m and roughly 315 kg at 2.5 mm or 504 kg at 4 mm.
06 / Worth knowing
What we will tell you that a reseller will not
-
The wrong product for the problem
Mass fixed hard to an existing wall gives far less than the same mass on an independent leaf. If we are told the wall cannot be thickened, we will say what the membrane will and will not achieve rather than quote the laboratory figure and let the site find out.
-
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.
-
A claim of being local to Boston
We manufacture in India and supply here. We do not run an office in this city and we will not pretend to, because you would find out on the first site visit.
Boston: questions we are actually asked
Do you manufacture soundBlanket mass loaded vinyl 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 decides the specification for a Boston project?
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.
Is this the right material for Boston conditions?
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.
When would material land on a Boston site?
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 will soundBlanket mass loaded vinyl not do?
Mass fixed hard to an existing wall gives far less than the same mass on an independent leaf. If we are told the wall cannot be thickened, we will say what the membrane will and will not achieve rather than quote the laboratory figure and let the site find out.
How is the order packed and what is the minimum?
The same minimums apply on export as on domestic orders. 2.5 mm and 4 mm, 10 rolls, 60 sq m. 6 mm and other thicknesses, 10 tonnes per thickness. A SoundBlanket roll is 5 x 1.2 m, which is 6 sq m. At 2100 kg per cubic metre a roll weighs about 31.5 kg at 2.5 mm and about 50.4 kg at 4 mm, so a 10 roll minimum is 60 sq m and roughly 315 kg at 2.5 mm or 504 kg at 4 mm. Rolls on core tubes, wrapped and end capped, 5 x 1.2 m. Weights on the packing list, because a full roll is heavy and site access matters.
Next step
Send a plan and a section, get a real build-up
A plan and a section is enough. We will come back with a build-up, a BOQ and a delivered date, and we will say so if what you are asking for will not work.
