Soundproof curtains in Prague

This comes from our own plant, not a trading desk. We do not have an office in your city and we will not invent one. What we can give you is factory pricing, consistent material and a technical answer before you commit.
01 / What it is
The material, and what it actually does on a Prague 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 Prague is mostly hotel conversions, apartments, production and studio spaces, offices, restaurants, clinics.
Panel block housing has concrete walls with good mass but no impact isolation, while older masonry stock has timber floors that pass footfall.
- 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 Prague.
02 / Data sheet
The published figures, unchanged by location
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.

If a consultant has set the target, we will quote against their figures rather than ours, and stay out of the scope they own. More on working with acoustic consultants.
03 / On the ground
What decides the build-up in Prague
- Protected buildings, internal fixes only
In the centre you often cannot alter the structure or the facade. The work has to be internal, shallow and ideally reversible, which rules out most thick framed systems.
- Conversions into guest rooms
Old buildings divided into hotel rooms and short lets put beds either side of walls that were never separating walls. Door and corridor details cause more complaints than anything else.
- A production city
Stages, edit rooms and post production spaces need the shell to isolate before anything else is decided. There is no partial credit on a room like that.
- Hard stone, long reverberation
Stone, plaster and tile in tall rooms hold sound for a long time. Speech stops being intelligible well before the room sounds obviously wrong.
- The housing stock
Panel block housing has concrete walls with good mass but no impact isolation, while older masonry stock has timber floors that pass footfall.
- The studio and content scene
A strong recording tradition, with rooms fitted into older buildings where the structure helps and the surfaces do not.
Architects working in Prague 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
What the Prague climate rules in and rules out
Prague is cool and damp, with long heating seasons and cold external walls, and that narrows the sensible material list before acoustics is even discussed.
Cold wall build-ups and long heating seasons mean interstitial condensation is a real risk behind any lining. PET felt is unaffected by damp air and will not feed mould where a fabric-faced mineral product would.
The risk we design against here is condensation behind linings in older, poorly insulated stock.
If the visual is fixed and the room still has to perform, that is a solvable problem and a conversation worth having early. See how we work with interior designers.
05 / Supply
How material reaches a Prague site
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Hamburg, then rail and road into Prague |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Hamburg |
| 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 Hamburg, then rail and road into Prague. 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 / Straight talk
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.

Suppliers who imply a Prague 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.
Prague: questions we are actually asked
Where are the soundproof curtains you supply to Prague actually made?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Prague as the manufacturer rather than through a dealer. Made at our own plant in India and shipped into Hamburg, then rail and road into the city, with the inland leg written into the dates we quote. You buy at factory prices with one consistent batch across the order.
What do you look at first on a Prague enquiry?
In the centre you often cannot alter the structure or the facade. The work has to be internal, shallow and ideally reversible, which rules out most thick framed systems. Old buildings divided into hotel rooms and short lets put beds either side of walls that were never separating walls. Door and corridor details cause more complaints than anything else. Those two things move the build-up far more than the panel figure does.
How does the Prague climate affect this product?
Prague is cool and damp, with long heating seasons and cold external walls. Cold wall build-ups and long heating seasons mean interstitial condensation is a real risk behind any lining. PET felt is unaffected by damp air and will not feed mould where a fabric-faced mineral product would. The failure we design against here is condensation behind linings in older, poorly insulated stock.
How does an order actually travel to Prague?
ships from: Palwal, Haryana, India, arrives at: Hamburg, then rail and road into Prague, 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.
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.

Drawings in, BOQ and a delivered date out
One drawing gets you a proper answer. Build-up, quantities, a delivered date, and an honest note on anything we think is the wrong approach.
