Manufactured in India, supplied in Ranchi
Soundproof curtains in Ranchi
We manufacture soundproof curtains at our own plant at Palwal in Haryana, India, and supply them into Ranchi. Ranchi is a state capital on a plateau, with mining sector offices and a growing institutional sector rather than heavy plant inside the city.

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 Ranchi 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 Ranchi is mostly government and institutional buildings, colleges, hospitals, corporate offices, auditoriums, hotels.
RC frame apartments and houses with hard floors, in towns built around mining and steel activity.
- 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 Ranchi.
02 / Data sheet
The published figures, unchanged by location
These figures are published and they do not move. The thing worth arguing about is not the number on the sheet, it is which grade and which build-up suits the room you are treating.

On a Ranchi job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.
03 / In this market
What we see driving Ranchi briefs
- Rooms built for listening
Assembly halls and lecture theatres in hard finishes defeat the speaker long before anyone calls the room echoey.
- New institutional build
Concrete and tile put up quickly, with the acoustic problem discovered at handover rather than designed out.
- Corporate and regional offices
Open floors with glass cabins where calls carry and meeting rooms sound hollow.
- Three days by road
A dedicated truck from Palwal, confirmed before dispatch, with samples sent ahead.
- The housing stock
RC frame apartments and houses with hard floors, in towns built around mining and steel activity.
- 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.
Architects working in Ranchi 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 / Durability
Why the climate in Ranchi changes the material, not the target
Ranchi is hot summers, mild winters and a distinct wet season, and that narrows the sensible material list before acoustics is even discussed.
PET felt handles the wet months without absorbing moisture or feeding mould. Timber and wood wool want a ventilated cavity and a stable indoor RH.
The risk we design against here is wet-season humidity behind linings.
For a Ranchi interior where the finish leads, we will say plainly what each option costs you acoustically. See how we work with interior designers.
05 / Getting it there
What the route into Ranchi actually looks like
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | three days |
| Dispatch | 2 to 4 working days |
| To site | three 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 twelve hundred kilometres, normally three 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.

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.
-
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.
-
Suppliers who imply a Ranchi 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.
Ranchi: questions we are actually asked
Where are the soundproof curtains you supply to Ranchi actually made?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Ranchi as the manufacturer rather than through a dealer. Ranchi is a state capital on a plateau, with mining sector offices and a growing institutional sector rather than heavy plant inside the city. You buy at factory prices with one consistent batch across the order.
Why would a Ranchi build-up differ from anywhere else?
Assembly halls and lecture theatres in hard finishes defeat the speaker long before anyone calls the room echoey. Concrete and tile put up quickly, with the acoustic problem discovered at handover rather than designed out. Those two things move the build-up far more than the panel figure does.
How does the Ranchi climate affect this product?
Ranchi is hot summers, mild winters and a distinct wet season. PET felt handles the wet months without absorbing moisture or feeding mould. Timber and wood wool want a ventilated cavity and a stable indoor RH. The failure we design against here is wet-season humidity behind linings.
What is the delivery time into Ranchi?
made at: Our own plant, Palwal, Haryana, reaches site in: three 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.
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?
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.

Send the drawings, get a straight answer
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.
