We are the manufacturer. There is no local office and we do not claim approvals we do not hold. What you get is factory pricing, one consistent batch across the order, and a straight answer on what the material will and will not do.

01 / Start here

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

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 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.

  • 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 Lisbon.

02 / Specification

Published specification, identical wherever we ship it

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

If a consultant has set the target, we will quote against their figures rather than ours, and stay out of the scope they own. More on working with acoustic consultants.

03 / On the ground

What the buildings in Lisbon do to the specification

  • 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.

  • 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.

  • 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.

  • School and campus buildings

    School buildings are hard surfaced with high ceilings, and canteens are the loudest rooms.

Architects working in Lisbon 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 / Climate and durability

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.

Designers get colour, pattern and CNC options with the absorption figure attached to each. See how we work with interior designers.

05 / Supply

How material reaches a Lisbon 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
PackingPalletised flat and film wrapped, cut sheets interleaved. Packing list and weights issued with the quote.
Lead time4 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 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.

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.

Minimum order, pet felt acoustic panels
Trial order200 panels, 6,400 sq ft, mixed thickness, GSM and colour
RecommendedFull 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.

06 / Read this first

Where this goes wrong, said plainly

  • 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.

  • 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 Lisbon 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.

FAQ

Lisbon: questions we are actually asked

Where are the PET felt acoustic panels you supply to Lisbon actually made?

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.

What changes the specification on a Lisbon job?

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.

Does Lisbon weather shorten the life of this material?

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.

When would material land on a Lisbon site?

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.

Where do PET felt acoustic panels fail to help?

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.

What is the minimum order and how is it packed?

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.
