Manufactured in India, supplied in Lisbon
Soundproof curtains in Lisbon
We manufacture soundproof curtains at our own plant at Palwal in Haryana, India, and supply them into Lisbon. Made at our own plant in India and shipped into Lisbon or Sines, then a short road run to site, with narrow street access planned into how we pack.

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 / What it is
The material, and what it actually does on a Lisbon 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 Lisbon is mostly hotel and short let conversions, apartments, restaurants, offices, clinics, studios.
Masonry and concrete blocks with tile and stone floors, in buildings that share walls and courtyards.
- 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 Lisbon.
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.

On a Lisbon job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.
03 / Local conditions
What decides the build-up in Lisbon
- Conversions put beds either side of old walls
A house divided into guest rooms turns internal partitions into separating walls overnight. Doors and corridors generate more complaints than the walls themselves.
- Timber floors, every floor
Footfall from above is the single most common complaint we hear from this city. It is a floor problem, and treating the ceiling below rarely fixes it.
- Hills and narrow streets
Access decides the delivery. Tell us the street and the stairwell and we break pallets down to what will actually get to the room.
- Late districts under homes
Venues in the old districts operate directly beneath apartments. Low frequency containment is what keeps the operation trading.
- The housing stock
Masonry and concrete blocks with tile and stone floors, in buildings that share walls and courtyards.
- The studio and content scene
Studios go into converted older buildings with good mass and hard surfaces, often with neighbours above.
If you are specifying for a Lisbon project, we can give you a section, a BOQ and the honest limits of each layer. See how we support architects.
04 / Climate and durability
What the Lisbon climate rules in and rules out
Lisbon is hot dry summers and mild wet winters, and that narrows the sensible material list before acoustics is even discussed.
The swing between a dry summer and a wet winter moves timber. PET felt is dimensionally stable across that swing; slat panels want a stable substrate and a ventilated fixing.
The risk we design against here is seasonal movement in timber and winter damp in unheated stock.
For a Lisbon interior where the finish leads, we will say plainly what each option costs you acoustically. See how we work with interior designers.
05 / Supply
How material reaches a Lisbon site
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Lisbon or Sines, then a short road run to site |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Lisbon or Sines |
| 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. Grooved panels and custom colours take longer, and we say so before you order, not after.
Sea freight into Lisbon or Sines, 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 / Read this first
Where this goes wrong, said plainly
-
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 Lisbon
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.
Lisbon: questions we are actually asked
Are these soundproof curtains made in Lisbon?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Lisbon as the manufacturer rather than through a dealer. Made at our own plant in India and shipped into Lisbon or Sines, then a short road run to site, with narrow street access planned into how we pack. You buy at factory prices with one consistent batch across the order.
What changes the specification on a Lisbon job?
A house divided into guest rooms turns internal partitions into separating walls overnight. Doors and corridors generate more complaints than the walls themselves. Footfall from above is the single most common complaint we hear from this city. It is a floor problem, and treating the ceiling below rarely fixes it. Those two things move the build-up far more than the panel figure does.
How does the Lisbon climate affect this product?
Lisbon is hot dry summers and mild wet winters. The swing between a dry summer and a wet winter moves timber. PET felt is dimensionally stable across that swing; slat panels want a stable substrate and a ventilated fixing. The failure we design against here is seasonal movement in timber and winter damp in unheated stock.
When would material land on a Lisbon site?
ships from: Palwal, Haryana, India, arrives at: Lisbon or Sines, then a short road run to site, dispatch: 4 to 7 working days. Standard items dispatch in 4 to 7 working days. Grooved panels and custom colours take longer, and we say so before you order, not after.
Where do soundproof curtains fail to help?
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.

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.
