Manufactured in India, supplied in Portugal
Soundproof curtains in Portugal
We manufacture soundproof curtains at our own plant at Palwal in Haryana, India, and supply them into Portugal. Made at our own plant in India and shipped into Sines, Lisbon or Leixões, with deep water capacity on the Atlantic coast keeping the sea leg simple.

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 Portugal 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 Portugal is mostly hotel and apartment conversions, restaurants, offices, clinics, schools, 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 Portugal.
02 / Specification
Published specification, identical wherever we ship it
Nothing below changes by location. The decisions that do change are grade, thickness and how the material is mounted, and those are covered further down.

On a Portugal job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.
03 / What drives the brief
The Portugal conditions that change the answer
- Atlantic damp
Our PET felt does not absorb moisture, shed fibre or feed mould, which matters on cold external walls in a mild wet climate where mineral products sag.
- Conversion, not construction
The structure is staying. Whatever we propose has to work inside the depth and the finishes that are already there, which rules out most thick framed systems.
- Timber floors in old buildings
Footfall passes straight down through the joists. A resilient layer under the new finish does more than anything applied to the ceiling below.
- Tourism programmes have fixed dates
Hotel openings do not move. We give honest dispatch and transit windows so the fit-out is not waiting on a container.
- 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.
We would rather argue about the build-up at design stage than on site. See how we support architects.
04 / Climate and durability
Why the climate in Portugal changes the material, not the target
Portugal 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 Portugal interior where the finish leads, we will say plainly what each option costs you acoustically. See how we work with interior designers.
05 / Route to site
How material reaches a Portugal site
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Sines, Lisbon or Leixões, then road to site |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Sines or Lisbon |
| 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 Sines, Lisbon or Leixões, then road 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
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.
-
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 Portugal
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.
Portugal: questions we are actually asked
Where are the soundproof curtains you supply to Portugal actually made?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Portugal as the manufacturer rather than through a dealer. Made at our own plant in India and shipped into Sines, Lisbon or Leixões, with deep water capacity on the Atlantic coast keeping the sea leg simple. You buy at factory prices with one consistent batch across the order.
What do you look at first on a Portugal enquiry?
The structure is staying. Whatever we propose has to work inside the depth and the finishes that are already there, which rules out most thick framed systems. Footfall passes straight down through the joists. A resilient layer under the new finish does more than anything applied to the ceiling below. Those two things move the build-up far more than the panel figure does.
Will this material last in the Portugal climate?
Portugal 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.
What is the delivery time into Portugal?
ships from: Palwal, Haryana, India, arrives at: Sines, Lisbon or Leixões, then road 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.
When are soundproof curtains the wrong purchase?
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.
How is the order packed and what is the minimum?
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
Send what you have. We will give you a layer by layer build-up, a bill of quantities and a date material lands, and we will flag anything in the brief that will not achieve what you want.
