SoundBlanket mass loaded vinyl in Trivandrum
We manufacture soundBlanket mass loaded vinyl at our own plant at Palwal in Haryana, India, and supply them into Trivandrum. Trivandrum is government and technology in a humid coastal climate, and it is the furthest point in the country from our plant.

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 Trivandrum
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 Trivandrum is mostly government and institutional buildings, technology park offices, hospitals, colleges, hotels, auditoriums.
Independent houses with high ceilings, tile floors and open plan layouts built for heat and very heavy monsoon, which rules out anything that absorbs moisture.
- 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 Trivandrum.
02 / Specification sheet
The published figures, unchanged by location
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.

On a Trivandrum job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.
03 / On the ground
What the buildings in Trivandrum do to the specification
- Our longest domestic run
Six days by road. We confirm dates before dispatch and send samples ahead so nothing is decided at the last moment.
- Humidity decides the material
PET felt does not absorb moisture, shed fibre or feed mould. On this coast that is the whole selection argument.
- Technology park floors
Open plans with glass and hard flooring that carry every call across the room.
- Institutional assembly spaces
Large halls in concrete where speech stops being intelligible well before the room sounds wrong.
- The housing stock
Independent houses with high ceilings, tile floors and open plan layouts built for heat and very heavy monsoon, which rules out anything that absorbs moisture.
- 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 Trivandrum 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 Trivandrum climate rules in and rules out
Trivandrum 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.
Interior designers tend to arrive with the look already decided. We will tell you which finish gets there without losing the acoustics. See how we work with interior designers.
05 / Supply
What the route into Trivandrum actually looks like
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | six days |
| Dispatch | 2 to 4 working days |
| To site | six 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 twenty six hundred kilometres, normally six days on a dedicated truck. It is the longest domestic run we operate.
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.
-
Square footage quoted before the room is understood
Anyone can price a wall. Working out how much material the room actually needs usually reduces the order, which is why not everyone does it.

Suppliers who imply a Trivandrum 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.
Trivandrum: questions we are actually asked
Is there a Trivandrum 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 Trivandrum as the manufacturer rather than through a dealer. Trivandrum is government and technology in a humid coastal climate, and it is the furthest point in the country from our plant. You buy at factory prices with one consistent batch across the order.
Why would a Trivandrum build-up differ from anywhere else?
Six days by road. We confirm dates before dispatch and send samples ahead so nothing is decided at the last moment. PET felt does not absorb moisture, shed fibre or feed mould. On this coast that is the whole selection argument. Those two things move the build-up far more than the panel figure does.
Does Trivandrum weather shorten the life of this material?
Trivandrum 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 Trivandrum?
made at: Our own plant, Palwal, Haryana, reaches site in: six 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.
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.

Send a plan and a section, get a real build-up
A plan and a section is enough. We will come back with a build-up, a BOQ and a delivered date, and we will say so if what you are asking for will not work.
