SoundBlanket mass loaded vinyl in Lisbon

We manufacture soundBlanket mass loaded vinyl at our own plant at Palwal in Haryana, India, and supply them into Lisbon. Made at our own plant in India and shipped into Lisbon or Sines, then a short road run to site, with narrow street access planned into how we pack.

  • Test reports sent on request, not just quoted

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 / What it is

The material, and what it actually does on a Lisbon job

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 Lisbon is mostly hotel and short let conversions, apartments, restaurants, offices, clinics, studios.

Masonry and concrete blocks with tile and stone floors, in buildings that share walls and courtyards.

  • 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 Lisbon.

02 / Specification

The numbers, and they do not move by city

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.

  • 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

Where a consultant is already engaged on a Lisbon project, we supply to their specification and send the test reports rather than describing them. More on working with acoustic consultants.

03 / Local conditions

What we see driving Lisbon briefs

  • Timber floors, every floor

    Footfall from above is the single most common complaint we hear from this city. It is a floor problem, and treating the ceiling below rarely fixes it.

  • Conversions put beds either side of old walls

    A house divided into guest rooms turns internal partitions into separating walls overnight. Doors and corridors generate more complaints than the walls themselves.

  • Hills and narrow streets

    Access decides the delivery. Tell us the street and the stairwell and we break pallets down to what will actually get to the room.

  • Late districts under homes

    Venues in the old districts operate directly beneath apartments. Low frequency containment is what keeps the operation trading.

  • The housing stock

    Masonry and concrete blocks with tile and stone floors, in buildings that share walls and courtyards.

  • The studio and content scene

    Studios go into converted older buildings with good mass and hard surfaces, often with neighbours above.

We would rather argue about the build-up at design stage than on site. See how we support architects.

04 / Conditions

What the Lisbon climate rules in and rules out

Lisbon is hot dry summers and mild wet winters, and that narrows the sensible material list before acoustics is even discussed.

The swing between a dry summer and a wet winter moves timber. PET felt is dimensionally stable across that swing; slat panels want a stable substrate and a ventilated fixing.

The risk we design against here is seasonal movement in timber and winter damp in unheated stock.

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 / Logistics

Supply into Lisbon, start to site

Supply into Lisbon
Ships fromPalwal, Haryana, India
Arrives atLisbon or Sines, then a short road run to site
Dispatch4 to 7 working days
FreightSea via Lisbon or Sines
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.

Sea freight into Lisbon or Sines, then a short road run to site. Air freight for samples and urgent quantities.

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.

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.

  • Local approvals that nobody actually holds

    We hold no Lisbon certification and we will not borrow one. The test data we publish is ours, and we will send the reports rather than describe them.

FAQ

Lisbon: questions we are actually asked

Are these soundBlanket mass loaded vinyl made in Lisbon?

No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Lisbon as the manufacturer rather than through a dealer. Made at our own plant in India and shipped into Lisbon or Sines, then a short road run to site, with narrow street access planned into how we pack. You buy at factory prices with one consistent batch across the order.

Why would a Lisbon build-up differ from anywhere else?

A house divided into guest rooms turns internal partitions into separating walls overnight. Doors and corridors generate more complaints than the walls themselves. Footfall from above is the single most common complaint we hear from this city. It is a floor problem, and treating the ceiling below rarely fixes it. Those two things move the build-up far more than the panel figure does.

Will this material last in the Lisbon climate?

Lisbon is hot dry summers and mild wet winters. The swing between a dry summer and a wet winter moves timber. PET felt is dimensionally stable across that swing; slat panels want a stable substrate and a ventilated fixing. The failure we design against here is seasonal movement in timber and winter damp in unheated stock.

What is the delivery time into Lisbon?

ships from: Palwal, Haryana, India, arrives at: Lisbon or Sines, then a short road run 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.

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.

How is the order packed and what is the minimum?

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.
