Soundproof curtains in Trivandrum
We manufacture soundproof curtains at our own plant at Palwal in Haryana, India, and supply them into Trivandrum. Trivandrum is government and technology in a humid coastal climate, and it is the furthest point in the country from our plant.

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 product, described honestly, for a Trivandrum brief
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 Trivandrum is mostly government and institutional buildings, technology park offices, hospitals, colleges, hotels, auditoriums.
Independent houses with high ceilings, tile floors and open plan layouts built for heat and very heavy monsoon, which rules out anything that absorbs moisture.
- 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 Trivandrum.
02 / Specification sheet
Published specification, identical wherever we ship it
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.

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 Trivandrum
- Humidity decides the material
PET felt does not absorb moisture, shed fibre or feed mould. On this coast that is the whole selection argument.
- Our longest domestic run
Six days by road. We confirm dates before dispatch and send samples ahead so nothing is decided at the last moment.
- Technology park floors
Open plans with glass and hard flooring that carry every call across the room.
- Institutional assembly spaces
Large halls in concrete where speech stops being intelligible well before the room sounds wrong.
- The housing stock
Independent houses with high ceilings, tile floors and open plan layouts built for heat and very heavy monsoon, which rules out anything that absorbs moisture.
- 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.
We would rather argue about the build-up at design stage than on site. See how we support architects.
04 / Climate
Why the climate in Trivandrum changes the material, not the target
Trivandrum 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.
For a Trivandrum interior where the finish leads, we will say plainly what each option costs you acoustically. See how we work with interior designers.
05 / Logistics
Supply into Trivandrum, start to site
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | six days |
| Dispatch | 2 to 4 working days |
| To site | six 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 twenty six hundred kilometres, normally six days on a dedicated truck. It is the longest domestic run we operate.
5 curtains.
| Any size | 5 pieces |

Curtains are made to size, so the minimum is counted in pieces rather than area.
06 / Before you buy
The things worth knowing before you place the order
-
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 Trivandrum certification and we will not borrow one. The test data we publish is ours, and we will send the reports rather than describe them.
Trivandrum: questions we are actually asked
Are these soundproof curtains made in Trivandrum?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Trivandrum as the manufacturer rather than through a dealer. Trivandrum is government and technology in a humid coastal climate, and it is the furthest point in the country from our plant. You buy at factory prices with one consistent batch across the order.
Why would a Trivandrum build-up differ from anywhere else?
Six days by road. We confirm dates before dispatch and send samples ahead so nothing is decided at the last moment. PET felt does not absorb moisture, shed fibre or feed mould. On this coast that is the whole selection argument. Those two things move the build-up far more than the panel figure does.
How does the Trivandrum climate affect this product?
Trivandrum 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.
How quickly can material reach a site in Trivandrum?
made at: Our own plant, Palwal, Haryana, reaches site in: six 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.
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
Tell us the room, we will tell you the build-up
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.
