This comes from our own plant, not a trading desk. We do not have an office in your city and we will not invent one. What we can give you is factory pricing, consistent material and a technical answer before you commit.
01 / The material
What this material is and where it earns its place in London
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 London is mostly flat conversions, offices, studios, bars and restaurants, schools, clinics.
Victorian and Edwardian terraces split into flats share a single brick party wall and a timber joist floor that was never built for two households. Newer stock is concrete with harder finishes.
- 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 London.
02 / Data sheet
The published figures, unchanged by location
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 London 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 decides the build-up in London
- Rail and Underground rumble
Structure borne, so surface panels do nothing. It needs mass and decoupling in the floor, wall or ceiling first.
- Damp winters
PET felt does not absorb moisture, shed fibre or feed mould, which matters in older stock with cold wall build-ups.
- Single brick party walls
A joist floor between two flats was never built for two households. Membrane plus an independent lining, then absorption.
- Night economy neighbours
Soho, Shoreditch, Camden and Clapham venues sit under flats. Bass containment and table-level comfort are two different jobs.
- The housing stock
Victorian and Edwardian terraces split into flats share a single brick party wall and a timber joist floor that was never built for two households. Newer stock is concrete with harder finishes.
- The studio and content scene
A deep music and broadcast culture, with rooms built into terraces, basements and converted industrial buildings where the party wall sets the limit.
Architects working in London 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
Durability in London, before acoustics is discussed
London is cool and damp, with long heating seasons and cold external walls, and that narrows the sensible material list before acoustics is even discussed.
Cold wall build-ups and long heating seasons mean interstitial condensation is a real risk behind any lining. PET felt is unaffected by damp air and will not feed mould where a fabric-faced mineral product would.
The risk we design against here is condensation behind linings in older, poorly insulated 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 / Getting it there
Supply into London, start to site
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Felixstowe, London Gateway or Southampton |
| Dispatch | 4 to 7 working days |
| Freight | Sea and air |
| 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 4 to 7 working days. Grooved and custom colours take longer, and we say so before you order, not after.
Sea freight to Felixstowe, London Gateway or Southampton. Air freight for samples and urgent quantities. Clearance through your agent or ours.
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.
06 / Before you buy
Four honest warnings before you buy
-
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.
-
Local approvals that nobody actually holds
We hold no London certification and we will not borrow one. The test data we publish is ours, and we will send the reports rather than describe them.
London: questions we are actually asked
Where are the soundBlanket mass loaded vinyl you supply to London actually made?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into London as the manufacturer rather than through a dealer. Made at our own plant in India, packed for container transit, specified with your drawings before anything ships. You buy at factory prices with one consistent batch across the order.
What do you look at first on a London enquiry?
Structure borne, so surface panels do nothing. It needs mass and decoupling in the floor, wall or ceiling first. A joist floor between two flats was never built for two households. Membrane plus an independent lining, then absorption. Those two things move the build-up far more than the panel figure does.
Will this material last in the London climate?
London is cool and damp, with long heating seasons and cold external walls. Cold wall build-ups and long heating seasons mean interstitial condensation is a real risk behind any lining. PET felt is unaffected by damp air and will not feed mould where a fabric-faced mineral product would. The failure we design against here is condensation behind linings in older, poorly insulated stock.
How does an order actually travel to London?
ships from: Palwal, Haryana, India, arrives at: Felixstowe, London Gateway or Southampton, dispatch: 4 to 7 working days. Standard items dispatch in 4 to 7 working days. Grooved 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.
What quantity do we have to order, and in what packaging?
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.
Next step
Tell us the room, we will tell you the build-up
Send what you have. We will give you a layer by layer build-up, a bill of quantities and a date material lands, and we will flag anything in the brief that will not achieve what you want.
