Manufactured in India, supplied in Patna
SoundBlanket mass loaded vinyl in Patna
We manufacture soundBlanket mass loaded vinyl at our own plant at Palwal in Haryana, India, and supply them into Patna. Patna is building institutional space quickly, and almost all of it involves large rooms where a lot of people need to hear one person.

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 / The material
What this material is and where it earns its place in Patna
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 Patna is mostly coaching institutes and colleges, hospitals, government buildings, auditoriums, offices, hotels.
RC frame with brick infill and hard floors, in buildings that sit close together on narrow lanes.
- 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 Patna.
02 / Data sheet
The numbers, and they do not move by city
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 |
Consultants get the raw data, not a sales sheet. That is the whole of our side of the job, and it is set out under working with acoustic consultants.
03 / On the ground
The Patna conditions that change the answer
- Rooms built for listening
Coaching halls and lecture rooms pack people into hard spaces. Intelligibility fails long before anyone describes the room as echoing.
- New institutional build
Concrete and tile put up quickly, with acoustics discovered at handover. Early drawings are worth more than extra material later.
- Medical privacy
Consult and counselling rooms where conversations have to stay in the room. Partition and door before panel.
- Two days by road
A manageable run, so freight is reasonable and samples arrive before the order is placed.
- The housing stock
RC frame with brick infill and hard floors, in buildings that sit close together on narrow lanes.
- 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 Patna practice, the useful thing is a detail you can put in a drawing set, not a brochure. See how we support architects.
04 / Conditions
The Patna climate decides the material list
Patna 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.
Designers get colour, pattern and CNC options with the absorption figure attached to each. See how we work with interior designers.
05 / Route to site
What the route into Patna actually looks like
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | two days |
| Dispatch | 2 to 4 working days |
| To site | 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 ten hundred kilometres, normally two 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
Where this goes wrong, said plainly
-
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.
-
Local approvals that nobody actually holds
We hold no Patna certification and we will not borrow one. The test data we publish is ours, and we will send the reports rather than describe them.
Patna: questions we are actually asked
Are these soundBlanket mass loaded vinyl made in Patna?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Patna as the manufacturer rather than through a dealer. Patna is building institutional space quickly, and almost all of it involves large rooms where a lot of people need to hear one person. You buy at factory prices with one consistent batch across the order.
Why would a Patna build-up differ from anywhere else?
Coaching halls and lecture rooms pack people into hard spaces. Intelligibility fails long before anyone describes the room as echoing. Concrete and tile put up quickly, with acoustics discovered at handover. Early drawings are worth more than extra material later. Those two things move the build-up far more than the panel figure does.
How does the Patna climate affect this product?
Patna 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.
When would material land on a Patna site?
made at: Our own plant, Palwal, Haryana, reaches site in: 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.
When are soundBlanket mass loaded vinyl the wrong purchase?
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.
