Manufactured in India, supplied in Nagpur
SoundBlanket mass loaded vinyl in Nagpur
We manufacture soundBlanket mass loaded vinyl at our own plant at Palwal in Haryana, India, and supply them into Nagpur. Nagpur sits at the centre of the country, which makes it a logistics hub and gives us an unusually even mix of industrial and institutional work.

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 / The material
What you are buying, and what it fixes in Nagpur
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 Nagpur is mostly warehouses and processing units, colleges, hospitals, offices, auditoriums, hotels.
Towers and chawls side by side, in RC frame with tile floors. Redevelopment stock shares slabs and lift cores, and monsoon damp rules out anything that holds moisture.
- 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 Nagpur.
02 / Specification sheet
One specification sheet, the same in every market
The specification below is the same everywhere we supply, because a specification that changed by city would not be a specification. What changes is which grade and build-up is the right buy, and that is what the rest of this page is about.
- 2.5 mmSTC 30, 5.25 kg per sq m. Ducts, light partitions, retrofit where depth is tight
- 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
| Density | 2100 kg per cubic metre |
|---|---|
| 2.5 mm | STC 30, 5.25 kg per sq m |
| 4 mm | STC 34, 8.4 kg per sq m |
| 6 mm | 12.6 kg per sq m, STC on request |
| Roll size | 5 x 1.2 m, 6 sq m per roll |
| Form | Limp sheet, cuts with a knife, seams lapped and sealed |
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 / In this market
What we see driving Nagpur briefs
- Warehouse volumes
Very large steel and concrete sheds where alarms and instructions have to be understood. Targeted absorption fixes intelligibility without touching the machines.
- Processing machinery
Continuous plant noise close to occupied areas. Enclosure at the source is the reliable answer.
- Institutional buildings
Colleges and hospitals in concrete and tile, where lecture rooms defeat the speaker and consult rooms offer no privacy.
- Dry heat
PET felt does not sag, shed fibre or degrade at high temperature, which matters in roof voids and rooms that get genuinely hot.
- The housing stock
Towers and chawls side by side, in RC frame with tile floors. Redevelopment stock shares slabs and lift cores, and monsoon damp rules out anything that holds moisture.
- The studio and content scene
The deepest film, dubbing and music production base in the country, with rooms built inside commercial and residential buildings under real neighbour constraints.
Architects working in Nagpur 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
The Nagpur climate decides the material list
Nagpur 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 Nagpur, start to site
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | two to three days |
| Dispatch | 2 to 4 working days |
| To site | two to three 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 eleven hundred kilometres, normally two to three 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.

The things worth knowing before you place the order
-
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.
-
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.
-
A claim of being local to Nagpur
We manufacture in India and supply here. We do not run an office in this city and we will not pretend to, because you would find out on the first site visit.
Nagpur: questions we are actually asked
Where are the soundBlanket mass loaded vinyl you supply to Nagpur actually made?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Nagpur as the manufacturer rather than through a dealer. Nagpur sits at the centre of the country, which makes it a logistics hub and gives us an unusually even mix of industrial and institutional work. You buy at factory prices with one consistent batch across the order.
What changes the specification on a Nagpur job?
Very large steel and concrete sheds where alarms and instructions have to be understood. Targeted absorption fixes intelligibility without touching the machines. Continuous plant noise close to occupied areas. Enclosure at the source is the reliable answer. Those two things move the build-up far more than the panel figure does.
Will this material last in the Nagpur climate?
Nagpur 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 Nagpur site?
made at: Our own plant, Palwal, Haryana, reaches site in: two to 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.
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 quantity do we have to order, and in what packaging?
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.
