Manufactured in India, supplied in Ludhiana
SoundBlanket mass loaded vinyl in Ludhiana
We manufacture soundBlanket mass loaded vinyl at our own plant at Palwal in Haryana, India, and supply them into Ludhiana. Ludhiana runs on textile and knitting machinery, and knitting machinery is genuinely loud for the people standing next to it all day.

We are the manufacturer. There is no local office and we do not claim approvals we do not hold. What you get is factory pricing, one consistent batch across the order, and a straight answer on what the material will and will not do.
01 / What it is
The product, described honestly, for a Ludhiana brief
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 Ludhiana is mostly knitting and textile units, workshops, worker areas, offices, showrooms, schools, clinics.
Independent houses and RC frame apartments with stone and tile floors, in towns with agricultural and light industrial activity nearby.
- 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 Ludhiana.
02 / Specification
One specification sheet, the same in every market
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.
- 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 |
Where a consultant is already engaged on a Ludhiana project, we supply to their specification and send the test reports rather than describing them. More on working with acoustic consultants.
03 / On the ground
What the buildings in Ludhiana do to the specification
- Industry beside housing
Units sit close to homes, so noise leaving the building matters as much as noise inside it. Those are two different treatments.
- One to two days by road
A dedicated truck from Palwal, with samples sent ahead so you can check the material before committing.
- Machine noise, all shift
Knitting and processing machines run continuously. The honest fix is enclosing or barriering the machine, not lining the walls of the hall.
- Hard halls, no intelligibility
Large sheds with steel and concrete surfaces make instructions and alarms hard to understand. Targeted absorption fixes that without touching the machines.
- The housing stock
Independent houses and RC frame apartments with stone and tile floors, in towns with agricultural and light industrial activity nearby.
- 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 and durability
Durability in Ludhiana, before acoustics is discussed
Ludhiana 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 Ludhiana interior where the finish leads, we will say plainly what each option costs you acoustically. See how we work with interior designers.
05 / Supply
Getting it to Ludhiana, with real dates
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | one to two days |
| Dispatch | 2 to 4 working days |
| To site | one to two 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 three hundred and fifty kilometres. Full loads on a dedicated truck, smaller consignments on a shared vehicle.
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 / Worth knowing
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 Ludhiana
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.
Ludhiana: questions we are actually asked
Do you manufacture soundBlanket mass loaded vinyl in Ludhiana?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Ludhiana as the manufacturer rather than through a dealer. Ludhiana runs on textile and knitting machinery, and knitting machinery is genuinely loud for the people standing next to it all day. You buy at factory prices with one consistent batch across the order.
What changes the specification on a Ludhiana job?
Knitting and processing machines run continuously. The honest fix is enclosing or barriering the machine, not lining the walls of the hall. Units sit close to homes, so noise leaving the building matters as much as noise inside it. Those are two different treatments. Those two things move the build-up far more than the panel figure does.
How does the Ludhiana climate affect this product?
Ludhiana 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.
How does an order actually travel to Ludhiana?
made at: Our own plant, Palwal, Haryana, reaches site in: one to two 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.
Is there a minimum order, and how does it arrive?
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.
