SoundBlanket mass loaded vinyl soundproofing membrane used in projects in Abu Dhabi

Manufactured in India, supplied in Nepal

SoundBlanket mass loaded vinyl in Nepal

We manufacture soundBlanket mass loaded vinyl at our own plant at Palwal in Haryana, India, and supply them into Nepal. Made at our own plant in India and moved overland through the border, which makes Nepal one of the few markets we reach entirely by road.

  • Made at our own plant, Palwal, Haryana, India
  • One batch across the order, no blending between runs
  • Test reports sent on request, not just quoted

We make this ourselves and ship it to you. No local branch, no borrowed certifications, no dealer margin. One batch across the whole order, and an honest answer when the product is wrong for the problem.

01 / The material

What this material is and where it earns its place in Nepal

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 Nepal is mostly hotels and guest houses, offices, hospitals, schools, assembly halls, houses.

Reinforced concrete frames with brick infill and hard floors, in buildings that sit very 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 Nepal.

02 / Specification sheet

One specification sheet, the same in every market

We publish one data sheet for every market. If a supplier quotes you a different figure for the same product in a different city, one of the two numbers is wrong.

  • 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

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 / Local conditions

What decides the build-up in Nepal

  • Reached entirely by road

    No port, no container, no sea leg. That keeps lead times short and makes small or repeat orders practical in a way they are not for most export markets.

  • Rebuilt and reinforced structures

    A great deal of stock has been rebuilt or retrofitted for seismic performance. Movement joints must stay free and an acoustic layer must not stiffen across them.

  • Hospitality in dense valleys

    Hotels and guest houses packed into tight streets where street noise reaches rooms through openings rather than walls.

  • Packing for mountain roads

    The final leg is often on rough road. We brace and wrap for that rather than for a smooth port transfer.

  • The housing stock

    Reinforced concrete frames with brick infill and hard floors, in buildings that sit very close together on narrow lanes.

  • The studio and content scene

    A growing music and content sector working out of rooms in residential buildings with neighbours on every side.

For a Nepal practice, the useful thing is a detail you can put in a drawing set, not a brochure. See how we support architects.

04 / Climate and durability

The Nepal climate decides the material list

Nepal 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.

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 / Supply

Getting it to Nepal, with real dates

Supply into Nepal
Ships fromPalwal, Haryana, India
Arrives atOverland through the India border, then road to site
Dispatch4 to 7 working days
FreightRoad via the India border
PackingRolls 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 time4 to 7 working days. Full container quantities scheduled against the vessel.

Standard items dispatch in 4 to 7 working days. Grooved panels and custom colours take longer, and we say so before you order, not after.

Overland by road through the India border, then on to site. No sea leg and no port handling.

The same minimums apply on export as on domestic orders.

Minimum order, soundblanket mass loaded vinyl
2.5 mm and 4 mm10 rolls, 60 sq m
6 mm and other thicknesses10 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 / Read this first

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 Nepal 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.

FAQ

Nepal: questions we are actually asked

Is there a Nepal 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 Nepal as the manufacturer rather than through a dealer. Made at our own plant in India and moved overland through the border, which makes Nepal one of the few markets we reach entirely by road. You buy at factory prices with one consistent batch across the order.

What do you look at first on a Nepal enquiry?

No port, no container, no sea leg. That keeps lead times short and makes small or repeat orders practical in a way they are not for most export markets. A great deal of stock has been rebuilt or retrofitted for seismic performance. Movement joints must stay free and an acoustic layer must not stiffen across them. Those two things move the build-up far more than the panel figure does.

Is this the right material for Nepal conditions?

Nepal 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 Nepal site?

ships from: Palwal, Haryana, India, arrives at: Overland through the India border, then road to site, dispatch: 4 to 7 working days. Standard items dispatch in 4 to 7 working days. 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?

The same minimums apply on export as on domestic orders. 2.5 mm and 4 mm, 10 rolls, 60 sq m. 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.
