Soundproof curtains in Visakhapatnam
We manufacture soundproof curtains at our own plant at Palwal in Haryana, India, and supply them into Visakhapatnam. Visakhapatnam is a port and a steel city on a cyclone coast, which means heavy industry and a climate that destroys the wrong material.

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 / The material
What you are buying, and what it fixes in Visakhapatnam
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 Visakhapatnam is mostly steel and port industry, control rooms, offices, hospitals, colleges, hotels.
RC frame houses and apartments with hard floors, in towns where units share walls and slabs.
- 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 Visakhapatnam.
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.

On a Visakhapatnam job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.
03 / Local conditions
What the buildings in Visakhapatnam do to the specification
- Heavy industry, low frequency
Mills, blowers and compressors put energy into the structure. Mass, isolation and enclosure are the only things that address it.
- Control rooms run long shifts
Operators listening for alarms need a low background before anything else matters.
- Salt air and cyclone coast
PET felt does not absorb moisture, rot or corrode, which matters where mineral products fail within a couple of seasons.
- Four days by road
A long run, confirmed before dispatch, with samples sent ahead of the order.
- The housing stock
RC frame houses and apartments with hard floors, in towns where units share walls and slabs.
- The studio and content scene
Studios go into basements, terrace rooms and back rooms with neighbours on every side and a generator somewhere in the lane. Isolating from the building has to come before treating the room.
For a Visakhapatnam practice, the useful thing is a detail you can put in a drawing set, not a brochure. See how we support architects.
04 / Conditions
Durability in Visakhapatnam, before acoustics is discussed
Visakhapatnam is warm and humid through most of the year, with a long wet season, and that narrows the sensible material list before acoustics is even discussed.
Humidity is the deciding factor. PET felt does not absorb moisture, shed fibre or feed mould, which is why it outlasts fabric-wrapped mineral wool in this climate. Wood wool and timber need a ventilated cavity behind them.
The risk we design against here is mould, sagging fabric finishes and swelling in timber.
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 / Logistics
Getting it to Visakhapatnam, with real dates
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | four days |
| Dispatch | 2 to 4 working days |
| To site | four days |
| Packing | Rolled and bagged with track and fixings listed separately. |
| Lead time | Made to size. Confirmed at quote. |
Standard items dispatch in 2 to 4 working days from our plant at Palwal. Grooved panels and custom colours take longer, and we say so before you order, not after.
By road from Palwal, roughly eighteen hundred kilometres, normally four days on a dedicated truck.
5 curtains.
| Any size | 5 pieces |

Curtains are made to size, so the minimum is counted in pieces rather than area.
06 / Straight talk
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.
-
Local approvals that nobody actually holds
We hold no Visakhapatnam certification and we will not borrow one. The test data we publish is ours, and we will send the reports rather than describe them.
Visakhapatnam: questions we are actually asked
Are these soundproof curtains made in Visakhapatnam?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Visakhapatnam as the manufacturer rather than through a dealer. Visakhapatnam is a port and a steel city on a cyclone coast, which means heavy industry and a climate that destroys the wrong material. You buy at factory prices with one consistent batch across the order.
What decides the specification for a Visakhapatnam project?
Mills, blowers and compressors put energy into the structure. Mass, isolation and enclosure are the only things that address it. Operators listening for alarms need a low background before anything else matters. Those two things move the build-up far more than the panel figure does.
Is this the right material for Visakhapatnam conditions?
Visakhapatnam is warm and humid through most of the year, with a long wet season. Humidity is the deciding factor. PET felt does not absorb moisture, shed fibre or feed mould, which is why it outlasts fabric-wrapped mineral wool in this climate. Wood wool and timber need a ventilated cavity behind them. The failure we design against here is mould, sagging fabric finishes and swelling in timber.
When would material land on a Visakhapatnam site?
made at: Our own plant, Palwal, Haryana, reaches site in: four days, dispatch: 2 to 4 working days. Standard items dispatch in 2 to 4 working days from our plant at Palwal. Grooved panels and custom colours take longer, and we say so before you order, not after.
What should you not buy soundproof curtains for?
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?
5 curtains. 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 a plan and a section, get a real build-up
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.
