Manufactured in India, supplied in Surat
SoundBlanket mass loaded vinyl in Surat
We manufacture soundBlanket mass loaded vinyl at our own plant at Palwal in Haryana, India, and supply them into Surat. Surat runs on textiles and diamonds, both of which put continuous machine noise next to people working long shifts.

01 / Start here
The product, described honestly, for a Surat 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 Surat is mostly textile and processing units, diamond workshops, offices, showrooms, schools, 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 Surat.
02 / Specification sheet
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.

- 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

Where a consultant is already engaged on a Surat 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 we see driving Surat briefs
- Humid and coastal
PET felt does not absorb moisture or feed mould, which matters where mineral products sag within a couple of seasons.
- Looms and processing machinery
Continuous high level noise for whole shifts. Enclosure or barrier at the machine is the honest fix, not lining the walls of the hall.
- Cutting and polishing rooms
Smaller, high frequency, and right next to people concentrating. Targeted treatment works here where it does not on a loom floor.
- Units beside housing
Noise leaving the building matters as much as noise inside it, and they need different treatments.
- 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 Surat practice, the useful thing is a detail you can put in a drawing set, not a brochure. See how we support architects.
04 / Climate
The Surat climate decides the material list
Surat 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.
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 Surat, 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.
06 / Before you buy
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.
-
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.
-
A claim of being local to Surat
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.
Surat: questions we are actually asked
Where are the soundBlanket mass loaded vinyl you supply to Surat actually made?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Surat as the manufacturer rather than through a dealer. Surat runs on textiles and diamonds, both of which put continuous machine noise next to people working long shifts. You buy at factory prices with one consistent batch across the order.
What do you look at first on a Surat enquiry?
Continuous high level noise for whole shifts. Enclosure or barrier at the machine is the honest fix, not lining the walls of the hall. Smaller, high frequency, and right next to people concentrating. Targeted treatment works here where it does not on a loom floor. Those two things move the build-up far more than the panel figure does.
Does Surat weather shorten the life of this material?
Surat 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.
How does an order actually travel to Surat?
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 should you not buy soundBlanket mass loaded vinyl for?
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.
