Manufactured in India, supplied in Chicago
Soundproof curtains in Chicago
We manufacture soundproof curtains at our own plant at Palwal in Haryana, India, and supply them into Chicago. Made at our own plant in India, shipped into an East or Gulf coast port and railed inland, with that leg quoted separately so the dates are real.

We make this ourselves and ship it to you. No local branch, no borrowed certifications, no dealer margin. One batch across the whole order, and an honest answer when the product is wrong for the problem.
01 / What it is
The material, and what it actually does on a Chicago 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 Chicago is mostly two-flats and three-flats, high-rise apartments, offices, venues, 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 Chicago.
02 / Specification sheet
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.
- Standard5.5 kg per sq m. Openings, stages, temporary partitions
| Build-up | 800 GSM face, foam, 3 mm SoundBlanket MLV core, foam, 800 GSM face |
|---|---|
| Total thickness | 10 to 12 mm |
| Weight | 5.5 kg per sq m |
| Reduction | Up to 30 dB |
| STC | 30 |
| Test standard | ASTM E90 |
| Standard sizes | 8 x 4 ft and 5 x 4 ft |
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 / What drives the brief
The Chicago conditions that change the answer
- Elevated rail past the window
Trains at window height put noise in through the glazing, not through the wall. The facade is where the money should go first.
- Brick outside, timber inside
Two-flats and three-flats have solid masonry outside and timber floors between families. Footfall travels down and masonry does nothing about it.
- Sealed against hard winters
Buildings close up for months and mechanical systems run hard, so sound accumulates inside rather than escaping.
- No port, so plan the inland leg
Everything arrives at a coast and rails in. We quote the sea leg and the inland leg separately.
- 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 Chicago project, we can give you a section, a BOQ and the honest limits of each layer. See how we support architects.
04 / Conditions
Durability in Chicago, before acoustics is discussed
Chicago 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 Chicago interior where the finish leads, we will say plainly what each option costs you acoustically. See how we work with interior designers.
05 / Supply
Getting it to Chicago, with real dates
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | An East or Gulf coast port, then rail and road inland |
| Dispatch | 4 to 7 working days |
| Freight | Sea, then rail inland |
| 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 an East or Gulf coast port, then rail and road to Chicago. 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
What we will tell you that a reseller will not
-
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.
-
Suppliers who imply a Chicago 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.
Chicago: questions we are actually asked
Where are the soundproof curtains you supply to Chicago actually made?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Chicago as the manufacturer rather than through a dealer. Made at our own plant in India, shipped into an East or Gulf coast port and railed inland, with that leg quoted separately so the dates are real. You buy at factory prices with one consistent batch across the order.
What changes the specification on a Chicago job?
Trains at window height put noise in through the glazing, not through the wall. The facade is where the money should go first. Two-flats and three-flats have solid masonry outside and timber floors between families. Footfall travels down and masonry does nothing about it. Those two things move the build-up far more than the panel figure does.
Will this material last in the Chicago climate?
Chicago 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 Chicago site?
ships from: Palwal, Haryana, India, arrives at: An East or Gulf coast port, then rail and road inland, 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 soundproof curtains 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. 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
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.
