Manufactured in India, supplied in Vapi
SoundBlanket mass loaded vinyl in Vapi
We manufacture soundBlanket mass loaded vinyl at our own plant at Palwal in Haryana, India, and supply them into Vapi. Vapi is an industrial belt, and almost everything we supply here goes into a working plant rather than an interior.

01 / The material
What this is, and what it changes in a Vapi room
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 Vapi is mostly process and chemical plants, utility and pump rooms, control rooms, offices, worker areas, clinics.
RC frame apartments and bungalows with stone and tile floors, in dry dusty conditions where open products collect dust.
- 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 Vapi.
02 / Specification
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.
- 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 / On the ground
What decides the build-up in Vapi
- Boundary noise matters
Housing sits close to industry here. Containing sound inside the site is a separate design from making the control room usable.
- Corrosive, humid air
PET felt does not absorb moisture, rot or feed mould, which matters in a coastal industrial climate.
- Plant runs continuously
Pumps, compressors and blowers do not stop, so the noise is constant rather than intermittent. Enclosure at the source is the only answer that holds.
- Control rooms need a low floor
Operators listening for alarms need background noise down before anything else matters.
- The housing stock
RC frame apartments and bungalows with stone and tile floors, in dry dusty conditions where open products collect dust.
- 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 Vapi practice, the useful thing is a detail you can put in a drawing set, not a brochure. See how we support architects.
04 / Durability
Why the climate in Vapi changes the material, not the target
Vapi is hot and dry for most of the year, with dust and high daytime surface temperatures, and that narrows the sensible material list before acoustics is even discussed.
Dust is the enemy of open-cell products. PET felt does not shed, does not hold dust in the way fabric-wrapped glass wool does, and wipes down. Timber needs a stable indoor RH or it moves.
The risk we design against here is dust ingress and thermal movement in long runs.
For a Vapi interior where the finish leads, we will say plainly what each option costs you acoustically. See how we work with interior designers.
05 / Route to site
Supply into Vapi, start to site
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | three days |
| Dispatch | 2 to 4 working days |
| To site | 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 twelve hundred kilometres, normally 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.

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.
-
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.

Suppliers who imply a Vapi 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.
Vapi: questions we are actually asked
Is there a Vapi factory behind this product?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Vapi as the manufacturer rather than through a dealer. Vapi is an industrial belt, and almost everything we supply here goes into a working plant rather than an interior. You buy at factory prices with one consistent batch across the order.
What changes the specification on a Vapi job?
Pumps, compressors and blowers do not stop, so the noise is constant rather than intermittent. Enclosure at the source is the only answer that holds. Housing sits close to industry here. Containing sound inside the site is a separate design from making the control room usable. Those two things move the build-up far more than the panel figure does.
Does Vapi weather shorten the life of this material?
Vapi is hot and dry for most of the year, with dust and high daytime surface temperatures. Dust is the enemy of open-cell products. PET felt does not shed, does not hold dust in the way fabric-wrapped glass wool does, and wipes down. Timber needs a stable indoor RH or it moves. The failure we design against here is dust ingress and thermal movement in long runs.
When would material land on a Vapi site?
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.
Where do soundBlanket mass loaded vinyl fail to help?
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.
