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 you are buying, and what it fixes in Vienna
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 Vienna is mostly gründerzeit apartments, offices, studios, restaurants, clinics, schools, hotels.
Gruenderzeit blocks have solid masonry walls and timber joist floors, so footfall carries even where airborne noise does not. Newer stock is concrete and much harder inside.
- 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 Vienna.
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 Vienna 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 Vienna do to the specification
- Gründerzeit rooms are tall and hard
High ceilings and lime plaster hold sound for a long time. A room can look perfect and still be unusable for speech until something absorbent goes high on the wall or across the ceiling.
- Timber floors between apartments
Footfall travels down through the joists into the flat below. A resilient layer under the finish does far more than anything applied to the ceiling underneath.
- Quiet hours are taken seriously
Neighbour complaints here are not shrugged off. The isolation layer is what protects a home studio, a practice room or a late venue from becoming somebody else problem.
- Trams and the Ring
Ground level trams and traffic put low frequency into the structure. Panels on a wall will not touch it, and we will say so rather than sell them.
- School and campus buildings
School and university rooms are built to a high standard with hard surfaces, and lecture spaces need intelligibility over a long tail.
We would rather argue about the build-up at design stage than on site. See how we support architects.
04 / Durability
What the Vienna climate rules in and rules out
Vienna 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.
For a Vienna interior where the finish leads, we will say plainly what each option costs you acoustically. See how we work with interior designers.
05 / Supply
Getting it to Vienna, with real dates
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Koper or Hamburg, then rail and road into Vienna |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Koper or Hamburg |
| 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 panels and custom colours take longer, and we say so before you order, not after.
Sea freight into Koper or Hamburg, then rail and road into Vienna. 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.
| 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.
-
A number chased without a measurement
If nobody has measured the room or set a target, the specification is a guess with a decimal point in it. We will ask for the target before we quote the quantity.

Suppliers who imply a Vienna 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.
Vienna: questions we are actually asked
Do you manufacture PET felt acoustic panels in Vienna?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Vienna as the manufacturer rather than through a dealer. Made at our own plant in India and routed through Koper or Hamburg, then rail and road into the city, with the inland leg written into the dates we quote. You buy at factory prices with one consistent batch across the order.
What decides the specification for a Vienna project?
High ceilings and lime plaster hold sound for a long time. A room can look perfect and still be unusable for speech until something absorbent goes high on the wall or across the ceiling. Footfall travels down through the joists into the flat below. A resilient layer under the finish does far more than anything applied to the ceiling underneath. Those two things move the build-up far more than the panel figure does.
Will this material last in the Vienna climate?
Vienna 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 Vienna?
ships from: Palwal, Haryana, India, arrives at: Koper or Hamburg, then rail and road into Vienna, 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.
What should you not buy PET felt acoustic panels for?
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.
Is there a minimum order, and how does it arrive?
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.

A plan and a section is enough. We will come back with a build-up, a BOQ and a delivered date, and we will say so if what you are asking for will not work.
