Soundproof curtains in Port Blair
We manufacture soundproof curtains at our own plant at Palwal in Haryana, India, and supply them into Port Blair. Port Blair is reached by ship from the mainland, so the sailing schedule governs the delivery date rather than our dispatch date does.

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 / The product
What you are buying, and what it fixes in Port Blair
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 Port Blair is mostly hotels and guest houses, administrative buildings, hospitals, schools, dining spaces, offices.
RC frame and timber construction with hard floors, in a very humid island climate where moisture resistance decides the material.
- 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 Port Blair.
02 / Specification
The numbers, and they do not move by city
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.

Where a consultant is already engaged on a Port Blair project, we supply to their specification and send the test reports rather than describing them. More on working with acoustic consultants.
03 / What drives the brief
The Port Blair conditions that change the answer
- The sailing sets the date
Scheduled vessels, not our dispatch, determine arrival. We work backwards from the sailing and tell you the real date.
- Get it right the first time
A replacement means waiting for the next sailing. We confirm the specification and send samples before anything ships.
- Salt air and heavy monsoon
PET felt does not absorb moisture, rot or corrode, which matters where almost everything else degrades quickly.
- Seismic islands
Buildings are designed to move, so a build-up must not stiffen across a movement joint.
- The housing stock
RC frame and timber construction with hard floors, in a very humid island climate where moisture resistance decides the material.
- The studio and content scene
No meaningful studio sector. Acoustic demand comes from community halls, resort entertainment rooms and offices instead.
Architects working in Port Blair 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 Port Blair climate rules in and rules out
Port Blair 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.
Interior designers tend to arrive with the look already decided. We will tell you which finish gets there without losing the acoustics. See how we work with interior designers.
05 / Getting it there
How material reaches a Port Blair site
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | a ship leg after Chennai |
| Dispatch | 2 to 4 working days |
| To site | a ship leg after Chennai |
| 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 to Chennai or Kolkata, then by ship to the islands. The sailing is scheduled and we plan the whole journey around it.
5 curtains.
| Any size | 5 pieces |

Curtains are made to size, so the minimum is counted in pieces rather than area.
06 / Straight talk
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.
-
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.
-
Local approvals that nobody actually holds
We hold no Port Blair certification and we will not borrow one. The test data we publish is ours, and we will send the reports rather than describe them.
Port Blair: questions we are actually asked
Is there a Port Blair factory behind this product?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Port Blair as the manufacturer rather than through a dealer. Port Blair is reached by ship from the mainland, so the sailing schedule governs the delivery date rather than our dispatch date does. You buy at factory prices with one consistent batch across the order.
Why would a Port Blair build-up differ from anywhere else?
Scheduled vessels, not our dispatch, determine arrival. We work backwards from the sailing and tell you the real date. A replacement means waiting for the next sailing. We confirm the specification and send samples before anything ships. Those two things move the build-up far more than the panel figure does.
Does Port Blair weather shorten the life of this material?
Port Blair 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 Port Blair site?
made at: Our own plant, Palwal, Haryana, reaches site in: a ship leg after Chennai, 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.
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.
What quantity do we have to order, and in what packaging?
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
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.
