01 / Start here
What you are buying, and what it fixes in Boston
A layered curtain with a mass loaded vinyl core, used where an opening has to stay an opening. It is the answer for a doorway, a stage, a partition that must move, not a substitute for a wall.
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.
- Full height with return Curtain taken floor to soffit with a side return and an overlap, because the gap is what leaks, not the fabric.
- Track with a seal Ceiling track plus a floor seal or drape, so the perimeter is closed when it is drawn.
- Double layer at a doorway Two curtains with an air gap where a single layer will not reach the target.
- What it will not do A curtain is only as good as its perimeter. Hung short, hung flat against a frame, or with a gap at the side, it will measure nothing like the figure on the sheet.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for soundproof curtains are on the main product page. This page covers what that means for a project in Boston.
02 / Data sheet
Published specification, identical wherever we ship it
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.
- Standard5.5 kg per sq m. Openings, stages, temporary partitions

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 / In this market
What we see driving Boston briefs
- 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
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.
For a Boston interior where the finish leads, we will say plainly what each option costs you acoustically. See how we work with interior designers.
05 / Getting it there
Supply into Boston, start to 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 |
| Freight | Sea into the East Coast |
| Packing | Rolled and bagged with track and fixings listed separately. |
| Lead time | Made to size. Confirmed at quote. |
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 5 piece minimum applies on export.
| Any size | 5 pieces |

Curtains are made to size, so the minimum is counted in pieces rather than area.
06 / Worth knowing
The things worth knowing before you place the order
-
The wrong product for the problem
A curtain is only as good as its perimeter. Hung short, hung flat against a frame, or with a gap at the side, it will measure nothing like the figure on the sheet. We quote the detail, not just the fabric.
-
A number chased without a measurement
If nobody has measured the room or set a target, the specification is a guess with a decimal point in it. We will ask for the target before we quote the quantity.
-
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
Where are the soundproof curtains you supply to Boston actually made?
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.
Why would a Boston build-up differ from anywhere else?
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.
Does Boston weather shorten the life of this material?
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 should you not buy soundproof curtains for?
A curtain is only as good as its perimeter. Hung short, hung flat against a frame, or with a gap at the side, it will measure nothing like the figure on the sheet. We quote the detail, not just the fabric.
Is there a minimum order, and how does it arrive?
The same 5 piece minimum applies on export. Any size, 5 pieces. Curtains are made to size, so the minimum is counted in pieces rather than area. Rolled and bagged with track and fixings listed separately.
Next step
Tell us the room, we will tell you the 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.
