01 / The product
What this is, and what it changes in a London room
Open cell foam shapes for high frequency control, and BassBloc, a high density absorber built for the low mid range where ordinary foam does nothing.
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.
- Corner loading Low frequency energy collects in corners, so absorber in the corners does more than the same area spread across a wall.
- First reflection points Mirror trick placement on side walls and ceiling, which is a handful of panels rather than a lined room.
- Behind a fabric frame Where the room has to look finished, absorber inside a frame rather than foam on show.
- What it will not do Thin foam on a wall is the most over-sold product in this industry. It controls flutter and nothing below it.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for acoustic foam and bass traps are on the main product page. This page covers what that means for a project in London.
02 / Specification
Published specification, identical wherever we ship it
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.
- Foam wedge and pyramidLow density. Flutter and high frequency only
- BassBloc100 kg per cubic metre. Low mid absorption, control rooms, live rooms

On a London job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.
03 / In this market
The London conditions that change the answer
- 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.
- 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.
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 / 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 / Logistics
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 | Compressed and boxed for foam, palletised flat for BassBloc. |
| Lead time | 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.
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.
| Acoustic foam | 200 sq ft, about 19 sq m |
|---|---|
| BassBloc | 300 sq ft, about 28 sq m |
| Bass traps | 10 pieces |
A BassBloc panel is 1800 x 900 mm, which is 1.62 sq m or about 17.4 sq ft, so the BassBloc minimum is roughly 17 panels.

What we will tell you that a reseller will not
-
The wrong product for the problem
Thin foam on a wall is the most over-sold product in this industry. It controls flutter and nothing below it. If the complaint is boom, bass from a neighbour, or a room that sounds uneven at low frequency, foam is the wrong purchase and we will say so.
-
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.

Suppliers who imply a London 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.

London: questions we are actually asked
Are these acoustic foam and BassBloc made in London?
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 decides the specification for a London project?
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.
Is this the right material for London conditions?
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.
Where do acoustic foam and BassBloc fail to help?
Thin foam on a wall is the most over-sold product in this industry. It controls flutter and nothing below it. If the complaint is boom, bass from a neighbour, or a room that sounds uneven at low frequency, foam is the wrong purchase and we will say so.
What is the minimum order and how is it packed?
The same minimums apply on export. Acoustic foam, 200 sq ft, about 19 sq m. BassBloc, 300 sq ft, about 28 sq m. Bass traps, 10 pieces. A BassBloc panel is 1800 x 900 mm, which is 1.62 sq m or about 17.4 sq ft, so the BassBloc minimum is roughly 17 panels. Compressed and boxed for foam, palletised flat for BassBloc.
