Manufactured in India, supplied in Seattle
Soundproof curtains in Seattle
We manufacture soundproof curtains at our own plant at Palwal in Haryana, India, and supply them into Seattle. Made at our own plant in India and shipped into Seattle or Tacoma, so the container lands at the city it is destined for rather than crossing the country first.

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 Seattle job
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 Seattle is mostly mass timber offices, tech campuses, multifamily, studios, 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.
- 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 Seattle.
02 / Data sheet
One specification sheet, the same in every market
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.

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 / On the ground
What the buildings in Seattle do to the specification
- Mass timber is still light
Exposed timber looks solid and performs nothing like concrete at low frequency. It also cannot be covered, because the timber is the design, so the acoustic work has to happen where it will not be seen.
- Rain on the roof
Metal and membrane roofs over open volumes turn heavy rain into a noise source. It is worth designing for rather than discovering in the first storm.
- Campus open plans
Large tech floors with exposed structure and hard finishes carry speech a long way. The ceiling plane and screens have to do what the walls are not there to do.
- The port is right here
Containers land at Seattle or Tacoma, so there is no cross-country leg. That keeps the landed cost and the date both predictable.
- 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.
Architects working in Seattle 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 Seattle, before acoustics is discussed
Seattle 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.
Interior designers tend to arrive with the look already decided. We will tell you which finish gets there without losing the acoustics. See how we work with interior designers.
05 / Logistics
Getting it to Seattle, with real dates
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Seattle or Tacoma, then a short road run to site |
| Dispatch | 4 to 7 working days |
| Freight | Sea into Seattle or Tacoma |
| 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 Seattle or Tacoma, then a short road run to site. Air freight for samples 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
Four honest warnings before you buy
-
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.
-
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.
-
Local approvals that nobody actually holds
We hold no Seattle certification and we will not borrow one. The test data we publish is ours, and we will send the reports rather than describe them.
Seattle: questions we are actually asked
Do you manufacture soundproof curtains in Seattle?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Seattle as the manufacturer rather than through a dealer. Made at our own plant in India and shipped into Seattle or Tacoma, so the container lands at the city it is destined for rather than crossing the country first. You buy at factory prices with one consistent batch across the order.
Why would a Seattle build-up differ from anywhere else?
Exposed timber looks solid and performs nothing like concrete at low frequency. It also cannot be covered, because the timber is the design, so the acoustic work has to happen where it will not be seen. Metal and membrane roofs over open volumes turn heavy rain into a noise source. It is worth designing for rather than discovering in the first storm. Those two things move the build-up far more than the panel figure does.
Does Seattle weather shorten the life of this material?
Seattle 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 Seattle?
ships from: Palwal, Haryana, India, arrives at: Seattle or Tacoma, then a short road run 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.
What quantity do we have to order, and in what packaging?
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
Send the drawings, get a straight answer
We quote from drawings, not from a square foot rate. Send a plan and the section through the critical wall or ceiling and you will get something you can actually build from.
