Manufactured in India, supplied in Vellore
SoundBlanket mass loaded vinyl in Vellore
We manufacture soundBlanket mass loaded vinyl at our own plant at Palwal in Haryana, India, and supply them into Vellore. Vellore is dominated by medical and engineering institutions, which makes clinical privacy and lecture intelligibility the two recurring briefs.

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 / Start here
The material, and what it actually does on a Vellore job
A limp, high density sheet that adds mass to a partition, floor or duct without adding depth. It is the barrier product, not an absorber, and it is the right answer when the problem is noise passing through a structure.
Work reaching us from Vellore is mostly teaching hospitals, engineering campuses, lecture theatres, hostels, offices, hotels.
RC frame houses and apartments with hard floors, built for heat and humidity with open plan layouts that carry sound room to room.
- Wall, decoupled Independent stud, membrane between the boards, cavity absorption, two boards. The membrane is one part of a system, never the whole answer.
- Floor, floating Membrane under a resilient layer and a floating deck, so impact energy is broken before it reaches the slab.
- Duct and plant wrap Membrane wrapped over the duct with a decoupling layer beneath, sealed at every lap.
- What it will not do Mass fixed hard to an existing wall gives far less than the same mass on an independent leaf. If we are told the wall cannot be thickened, we will say what the membrane will and will not achieve rather than quote the laboratory figure and let the site find out.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for SoundBlanket MLV are on the main product page. This page covers what that means for a project in Vellore.
02 / Specification
The numbers, and they do not move by city
Nothing below changes by location. The decisions that do change are grade, thickness and how the material is mounted, and those are covered further down.

- 4 mmSTC 34, 8.4 kg per sq m. Party walls, floors, plant rooms, the common specification
- 6 mm12.6 kg per sq m. Machine enclosures and low frequency problems

On a Vellore 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 Vellore do to the specification
- Clinical privacy
Consult and counselling rooms where conversations must not carry. That is a partition and door question before it is a panel question.
- Lecture theatres
Large teaching rooms where every seat has to hear clearly, usually in concrete and tile.
- Hostels and residences
Students living next to each other and to corridors, where separating detail does the work.
- Five 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, built for heat and humidity with open plan layouts that carry sound room to room.
- 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 Vellore practice, the useful thing is a detail you can put in a drawing set, not a brochure. See how we support architects.
04 / Conditions
Why the climate in Vellore changes the material, not the target
Vellore 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 / Getting it there
Supply into Vellore, start to site
| 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, wrapped and end capped, 5 x 1.2 m. Weights on the packing list, because a full roll is heavy and site access matters. |
| Lead time | 4 to 7 working days. Full container quantities scheduled against the vessel. |
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 two hundred kilometres, normally five days on a dedicated truck.
10 rolls for 2.5 mm and 4 mm. Other thicknesses are made to order at 10 tonnes per thickness.
| 2.5 mm | 10 rolls, 60 sq m, about 315 kg |
|---|---|
| 4 mm | 10 rolls, 60 sq m, about 504 kg |
| 6 mm and other thicknesses | 10 tonnes per thickness |
A SoundBlanket roll is 5 x 1.2 m, which is 6 sq m. At 2100 kg per cubic metre a roll weighs about 31.5 kg at 2.5 mm and about 50.4 kg at 4 mm, so a 10 roll minimum is 60 sq m and roughly 315 kg at 2.5 mm or 504 kg at 4 mm.
06 / Straight talk
What we will tell you that a reseller will not
-
The wrong product for the problem
Mass fixed hard to an existing wall gives far less than the same mass on an independent leaf. If we are told the wall cannot be thickened, we will say what the membrane will and will not achieve rather than quote the laboratory figure and let the site find out.
-
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 Vellore certification and we will not borrow one. The test data we publish is ours, and we will send the reports rather than describe them.
Vellore: questions we are actually asked
Do you manufacture soundBlanket mass loaded vinyl in Vellore?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Vellore as the manufacturer rather than through a dealer. Vellore is dominated by medical and engineering institutions, which makes clinical privacy and lecture intelligibility the two recurring briefs. You buy at factory prices with one consistent batch across the order.
What changes the specification on a Vellore job?
Consult and counselling rooms where conversations must not carry. That is a partition and door question before it is a panel question. Large teaching rooms where every seat has to hear clearly, usually in concrete and tile. Those two things move the build-up far more than the panel figure does.
Is this the right material for Vellore conditions?
Vellore 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.
What is the delivery time into Vellore?
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 soundBlanket mass loaded vinyl not do?
Mass fixed hard to an existing wall gives far less than the same mass on an independent leaf. If we are told the wall cannot be thickened, we will say what the membrane will and will not achieve rather than quote the laboratory figure and let the site find out.
What is the minimum order and how is it packed?
10 rolls for 2.5 mm and 4 mm. Other thicknesses are made to order at 10 tonnes per thickness. 2.5 mm, 10 rolls, 60 sq m, about 315 kg. 4 mm, 10 rolls, 60 sq m, about 504 kg. 6 mm and other thicknesses, 10 tonnes per thickness. A SoundBlanket roll is 5 x 1.2 m, which is 6 sq m. At 2100 kg per cubic metre a roll weighs about 31.5 kg at 2.5 mm and about 50.4 kg at 4 mm, so a 10 roll minimum is 60 sq m and roughly 315 kg at 2.5 mm or 504 kg at 4 mm. Rolls on core tubes, wrapped and end capped, 5 x 1.2 m. Weights on the packing list, because a full roll is heavy and site access matters.
