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 / Start here
What this material is and where it earns its place in London
The blocking side of the range taken together: mass loaded vinyl, resilient layers, cavity absorption and the build-ups they belong in. This is the page for someone whose problem is noise getting through, not a room that sounds wrong.
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.
- Independent leaf A second wall that does not touch the first. Nothing else comes close for the money.
- Resilient bar Where a full independent leaf will not fit. Effective, and very easy to short circuit with one wrong screw.
- Floating floor Resilient layer and deck, to break impact energy before it reaches the structure.
- What it will not do Soundproofing fails at the gaps, not the materials. A service penetration, a back to back socket, or a door undercut will undo a correctly built wall.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for our soundproofing materials are on the main product page. This page covers what that means for a project in London.

02 / Specification
The numbers, and they do not move by city
These figures are published and they do not move. The thing worth arguing about is not the number on the sheet, it is which grade and which build-up suits the room you are treating.
- Light retrofit2.5 mm membrane. Where depth is not available
- Standard partition4 mm membrane on an independent leaf. The common specification
- Heavy6 mm membrane and full decoupling. Plant, machine enclosure, low frequency

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.
03 / In this market
What the buildings in London do to the specification
- Rail and Underground rumble
Structure borne, so surface panels do nothing. It needs mass and decoupling in the floor, wall or ceiling first.
- 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.
- Damp winters
PET felt does not absorb moisture, shed fibre or feed mould, which matters in older stock with cold wall build-ups.
- Plant and HVAC
Older stock has radiators and open windows, newer stock has mechanical ventilation with heat recovery, so duct-borne noise is a newer problem than the buildings suggest.
- 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.
For a London 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
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.
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 / Route to site
What the route into London actually looks like
| 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, boards palletised, fixings and tapes listed on the same packing list. |
| Lead time | 4 to 7 working days for stock items. |
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.

What we will tell you that a reseller will not
-
The wrong product for the problem
Soundproofing fails at the gaps, not the materials. A service penetration, a back to back socket, or a door undercut will undo a correctly built wall. We would rather spend the conversation on the detail than on the product.
-
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.
-
A claim of being local to London
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.

How it looks once it is installed
London: questions we are actually asked
Where are the soundproofing materials 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.
Why would a London build-up differ from anywhere else?
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.
Does London weather shorten the life of this material?
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.
What is the delivery time into 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 soundproofing materials the wrong purchase?
Soundproofing fails at the gaps, not the materials. A service penetration, a back to back socket, or a door undercut will undo a correctly built wall. We would rather spend the conversation on the detail than on the product.
How is the order packed and what is the minimum?
Minimum order is confirmed with the quote. Rolls on core tubes, boards palletised, fixings and tapes listed on the same packing list.
Next step
Tell us the room, we will tell you the build-up
We quote from drawings, not from a square foot rate. Send a plan and the section through the critical wall or ceiling and you will get something you can actually build from.
