Manufactured in India, supplied in Guwahati
SoundBlanket mass loaded vinyl in Guwahati
We manufacture soundBlanket mass loaded vinyl at our own plant at Palwal in Haryana, India, and supply them into Guwahati. Guwahati is the gateway to the Northeast, so a good share of what we send here continues onward to sites across the region.

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 Guwahati
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 Guwahati is mostly hotels, hospitals, colleges, government buildings, offices, auditoriums, houses.
RC frame and timber construction with hard floors, built for very heavy rainfall and high humidity year round.
- 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 Guwahati.
02 / Specification
The numbers, and they do not move by city
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 |
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.

What the buildings in Guwahati do to the specification
- Seismic detailing comes first
Buildings here are designed to move. Movement joints have to stay free, so the build-up must respect the structure rather than bridge it rigidly.
- A gateway, not just a destination
Material often continues into the Northeast on rougher roads. We brace and wrap for that second leg when you tell us it is happening.
- High humidity most of the year
PET felt does not hold moisture or feed mould, which matters where mineral products sag within a couple of seasons.
- Four days by road
A long run, confirmed before dispatch, with samples sent ahead of the order.
- The housing stock
RC frame and timber construction with hard floors, built for very heavy rainfall and high humidity year round.
- 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.
Architects working in Guwahati 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 / Conditions
What the Guwahati climate rules in and rules out
Guwahati 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.
Designers get colour, pattern and CNC options with the absorption figure attached to each. See how we work with interior designers.
05 / Getting it there
Supply into Guwahati, start to site
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | four days |
| Dispatch | 2 to 4 working days |
| To site | four 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 nineteen hundred kilometres, normally four 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 Guwahati
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.
Guwahati: questions we are actually asked
Are these soundBlanket mass loaded vinyl made in Guwahati?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Guwahati as the manufacturer rather than through a dealer. Guwahati is the gateway to the Northeast, so a good share of what we send here continues onward to sites across the region. You buy at factory prices with one consistent batch across the order.
What decides the specification for a Guwahati project?
Buildings here are designed to move. Movement joints have to stay free, so the build-up must respect the structure rather than bridge it rigidly. Material often continues into the Northeast on rougher roads. We brace and wrap for that second leg when you tell us it is happening. Those two things move the build-up far more than the panel figure does.
Is this the right material for Guwahati conditions?
Guwahati 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.
How does an order actually travel to Guwahati?
made at: Our own plant, Palwal, Haryana, reaches site in: four 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.
How is the order packed and what is the minimum?
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.
