Manufactured in India, supplied in Denver
Soundproof curtains in Denver
We manufacture soundproof curtains at our own plant at Palwal in Haryana, India, and supply them into Denver. Made at our own plant in India, shipped into Houston or the West Coast and trucked inland, with the road leg quoted separately so the programme runs on real dates.

01 / The material
What you are buying, and what it fixes in Denver
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 Denver is mostly multifamily apartments, offices, breweries and taprooms, schools, clinics, home theatres.
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 Denver.
02 / Specification 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

On a Denver job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.
03 / On the ground
The Denver conditions that change the answer
- Light frame multifamily at volume
Thousands of units built to the same separating detail. If the detail underperforms it underperforms everywhere, which makes it worth solving on the drawing.
- Taprooms and hard rooms
Breweries and taprooms are concrete, steel and glass by design. They are loud by construction, not by accident, and the ceiling plane is usually the only place to fix it.
- No port, so plan the road leg
Everything arrives at a coast and drives in. We quote the sea leg and the road leg separately so you can see where the time goes.
- Dry air, sealed buildings
Our PET felt does not shed fibre or degrade in dry conditions, and it holds its shape in rooms that stay closed and conditioned.
- 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.
For a Denver practice, the useful thing is a detail you can put in a drawing set, not a brochure. See how we support architects.
04 / Durability
The Denver climate decides the material list
Denver 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 Denver 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 Denver, start to site
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Houston or the West Coast, then road inland |
| Dispatch | 4 to 7 working days |
| Freight | Sea, then road 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 Houston or the West Coast, then road inland to Denver. 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.
-
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 Denver
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.
Denver: questions we are actually asked
Where are the soundproof curtains you supply to Denver actually made?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Denver as the manufacturer rather than through a dealer. Made at our own plant in India, shipped into Houston or the West Coast and trucked inland, with the road leg quoted separately so the programme runs on real dates. You buy at factory prices with one consistent batch across the order.
What changes the specification on a Denver job?
Thousands of units built to the same separating detail. If the detail underperforms it underperforms everywhere, which makes it worth solving on the drawing. Breweries and taprooms are concrete, steel and glass by design. They are loud by construction, not by accident, and the ceiling plane is usually the only place to fix it. Those two things move the build-up far more than the panel figure does.
Does Denver weather shorten the life of this material?
Denver 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 Denver site?
ships from: Palwal, Haryana, India, arrives at: Houston or the West Coast, then 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 is the minimum order and how is it packed?
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
Drawings in, BOQ and a delivered date out
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.
