Manufactured in India, supplied in Salem
Soundproofing materials in Salem
We manufacture soundproofing materials at our own plant at Palwal in Haryana, India, and supply them into Salem. Salem is steel and textiles in dry inland heat, so most of what we supply goes into working plant rather than interiors.

- Made at our own plant, Palwal, Haryana, India
- One batch across the order, no blending between runs
We make this ourselves and ship it to you. No local branch, no borrowed certifications, no dealer margin. One batch across the whole order, and an honest answer when the product is wrong for the problem.
01 / What it is
The material, and what it actually does on a Salem job
The blocking side of the range taken together: mass loaded vinyl, resilient layers, cavity absorption and the build-ups they belong in. This is the page for someone whose problem is noise getting through, not a room that sounds wrong.
Work reaching us from Salem is mostly steel and textile plant, workshops, offices, canteens, colleges, hospitals.
RC frame houses and apartments with hard floors, built for heat and humidity with open plan layouts that carry sound room to room.
- Independent leaf A second wall that does not touch the first. Nothing else comes close for the money.
- Resilient bar Where a full independent leaf will not fit. Effective, and very easy to short circuit with one wrong screw.
- Floating floor Resilient layer and deck, to break impact energy before it reaches the structure.
- What it will not do Soundproofing fails at the gaps, not the materials. A service penetration, a back to back socket, or a door undercut will undo a correctly built wall.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for our soundproofing materials are on the main product page. This page covers what that means for a project in Salem.

02 / Specification
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.
- Light retrofit2.5 mm membrane. Where depth is not available
- Standard partition4 mm membrane on an independent leaf. The common specification
- Heavy6 mm membrane and full decoupling. Plant, machine enclosure, low frequency

Consultants get the raw data, not a sales sheet. That is the whole of our side of the job, and it is set out under working with acoustic consultants.
03 / In this market
What we see driving Salem briefs
- Plant noise is a mass problem
Mills, compressors and processing machinery are low frequency and structure-borne. Panels on a wall will not touch them.
- Hot buildings
PET felt does not sag, shed fibre or degrade at high temperature, which matters in a roof void above a hot process.
- Intelligibility on the floor
Large sheds where instructions and alarms have to be understood. Targeted absorption fixes that without touching the machines.
- Five days by road
A long run, confirmed before dispatch, with samples sent ahead.
- Plant and HVAC
Split units, VRF outdoor banks and diesel generator sets sit close to occupied areas, often on the same terrace as a bedroom. Generator enclosure and condenser screening are the recurring jobs.
- The housing stock
RC frame houses and apartments with hard floors, built for heat and humidity with open plan layouts that carry sound room to room.
If you are specifying for a Salem project, we can give you a section, a BOQ and the honest limits of each layer. See how we support architects.
04 / Climate
The Salem climate decides the material list
Salem 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.
Designers get colour, pattern and CNC options with the absorption figure attached to each. See how we work with interior designers.
05 / Supply
Getting it to Salem, with real dates
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | five days |
| Dispatch | 2 to 4 working days |
| To site | five days |
| Packing | Rolls on core tubes, boards palletised, fixings and tapes listed on the same packing list. |
| Lead time | 4 to 7 working days for stock items. |
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 three hundred kilometres, normally five days on a dedicated truck.

Where this goes wrong, said plainly
-
The wrong product for the problem
Soundproofing fails at the gaps, not the materials. A service penetration, a back to back socket, or a door undercut will undo a correctly built wall. We would rather spend the conversation on the detail than on the product.
-
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 Salem 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.

The product on finished jobs
Salem: questions we are actually asked
Where are the soundproofing materials you supply to Salem actually made?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Salem as the manufacturer rather than through a dealer. Salem is steel and textiles in dry inland heat, so most of what we supply goes into working plant rather than interiors. You buy at factory prices with one consistent batch across the order.
What decides the specification for a Salem project?
Mills, compressors and processing machinery are low frequency and structure-borne. Panels on a wall will not touch them. PET felt does not sag, shed fibre or degrade at high temperature, which matters in a roof void above a hot process. Those two things move the build-up far more than the panel figure does.
How does the Salem climate affect this product?
Salem 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 Salem?
made at: Our own plant, Palwal, Haryana, reaches site in: five 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 will soundproofing materials not do?
Soundproofing fails at the gaps, not the materials. A service penetration, a back to back socket, or a door undercut will undo a correctly built wall. We would rather spend the conversation on the detail than on the product.
What is the minimum order and how is it packed?
Minimum order is confirmed with the quote. Rolls on core tubes, boards palletised, fixings and tapes listed on the same packing list.
