01 / What it is
The product, described honestly, for a London brief
A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. It absorbs mid and high frequency energy and finishes as the visible surface, so it is both the acoustic layer and the finish.
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.
- Direct to wall Panel bonded or mechanically fixed flat to the substrate. Simplest, and the weakest at low frequency.
- On a 25 to 50 mm air gap The same panel on battens. The air gap moves absorption down in frequency at no extra material cost, and is the cheapest improvement available.
- Over a porous backing Panel over mineral or PET backing where the room needs genuine low mid control.
- What it will not do It absorbs. It does not block.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for PET felt panels are on the main product page. This page covers what that means for a project in London.
02 / Specification sheet
One specification sheet, the same in every market
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.
- EchoCore 151500 GSM. Offices, classrooms, general commercial
- EchoPro 181800 GSM. Studios, auditoria, rooms with a written RT target
- EchoMax 222200 GSM. High occupancy and high level spaces

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.

What the buildings in London do to the specification
- Damp winters
PET felt does not absorb moisture, shed fibre or feed mould, which matters in older stock with cold wall build-ups.
- 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.
- School and campus buildings
School buildings mix Victorian halls with post war system build and new academies, so hard floors, high ceilings and long corridors are the constant.
We would rather argue about the build-up at design stage than on site. See how we support architects.
04 / Climate
Why the climate in London changes the material, not the target
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.
Designers get colour, pattern and CNC options with the absorption figure attached to each. See how we work with interior designers.
05 / Logistics
Getting it to London, with real dates
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Felixstowe, London Gateway or Southampton |
| Dispatch | 4 to 7 working days |
| Freight | Sea and air |
| Packing | Palletised flat and film wrapped, cut sheets interleaved. Packing list and weights issued with the quote. |
| Lead time | 4 to 7 working days for standard colours and thicknesses. Grooved and custom colours take longer, and we say so before you order. |
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.
200 panels for a trial order, in any mix of thickness, GSM and colour. Beyond a trial we would rather quote a container load, because the price per panel and the freight per panel both fall sharply and a part load pays for space it does not use.
| Trial order | 200 panels, 6,400 sq ft, mixed thickness, GSM and colour |
|---|---|
| Recommended | Full container, for the best price per panel and the lowest freight per panel |
A panel is 1220 x 2440 mm, which is 32 sq ft.

What we will tell you that a reseller will not
-
The wrong product for the problem
It absorbs. It does not block. A PET panel on a shared wall will make the room sound better and will not stop the neighbour being heard. If the brief is stopping noise passing through a wall or floor, the answer is mass and decoupling, and we will say so before quoting.
-
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.

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
Do you manufacture PET felt acoustic panels 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 changes the specification on a London job?
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.
How does the London climate affect this product?
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.
What will PET felt acoustic panels not do?
It absorbs. It does not block. A PET panel on a shared wall will make the room sound better and will not stop the neighbour being heard. If the brief is stopping noise passing through a wall or floor, the answer is mass and decoupling, and we will say so before quoting.
How is the order packed and what is the minimum?
200 panels for a trial order, in any mix of thickness, GSM and colour. Beyond a trial we would rather quote a container load, because the price per panel and the freight per panel both fall sharply and a part load pays for space it does not use. Trial order, 200 panels, 6,400 sq ft, mixed thickness, GSM and colour. Recommended, Full container, for the best price per panel and the lowest freight per panel. A panel is 1220 x 2440 mm, which is 32 sq ft. Palletised flat and film wrapped, cut sheets interleaved. Packing list and weights issued with the quote.
