HVAC, plant and machine noise control in Vienna
Noise with a source. Almost every honest fix is at the machine, the duct or the plant room, and almost nothing useful happens by lining the far wall of the occupied space. Mechanical ventilation with heat recovery in newer buildings, so duct-borne noise is the source.
- At source
- Enclosure, barrier or anti vibration mounts at the machine.
- In the path
- Duct lining, attenuators and lagging on the first run out of the plant.
- At the receiver
- Only after the first two, and only for what is left.

01 / The material
What this is, and what it changes in a Vienna room
Noise with a source. Almost every honest fix is at the machine, the duct or the plant room, and almost nothing useful happens by lining the far wall of the occupied space.
Mechanical ventilation with heat recovery in newer buildings, so duct-borne noise is the source.
Work reaching us from Vienna is mostly gründerzeit apartments, offices, studios, restaurants, clinics, schools, hotels.
- 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.
- At source Enclosure, barrier or anti vibration mounts at the machine.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for HVAC and plant noise control are on the main product page. This page covers what that means for a project in Vienna.
02 / The build-up
The build-up, layer by layer
-
Layer 1
SoundBlanket mass loaded vinyl
A limp, high density sheet that adds mass to a partition, floor or duct without adding depth. In Vienna, mechanical ventilation with heat recovery in newer buildings, so duct-borne noise is the source.
Floor, floating. Membrane under a resilient layer and a floating deck, so impact energy is broken before it reaches the slab.
-
Layer 2
Soundproofing materials
The blocking side of the range taken together: mass loaded vinyl, resilient layers, cavity absorption and the build-ups they belong in. In Vienna, concert halls, church buildings and civic rooms are long-reverberation volumes where any intervention must be reversible.
Independent leaf. A second wall that does not touch the first. Nothing else comes close for the money.
-
Layer 3
Acoustic foam and BassBloc
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. In Vienna, school and university rooms are built to a high standard with hard surfaces, and lecture spaces need intelligibility over a long tail.
Corner loading. Low frequency energy collects in corners, so absorber in the corners does more than the same area spread across a wall.
If you are specifying for a Vienna project, we can give you a section, a BOQ and the honest limits of each layer. See how we support architects.
03 / On the ground
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.

Mechanical ventilation with heat recovery in newer buildings, so duct-borne noise is the source.
04 / Room by room
Room by room, on a typical Vienna job
-
At source
Enclosure, barrier or anti vibration mounts at the machine. 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.
- SoundBlanket mass loaded vinyl, 2100 kg per cubic metre
- Acoustic foam and BassBloc, 20 mm
- Ceiling baffles and clouds, Made to the drawing, standard and custom
-
In the path
Duct lining, attenuators and lagging on the first run out of the plant. 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.
- SoundBlanket mass loaded vinyl, STC 30, 5.25 kg per sq m
- Acoustic foam and BassBloc, 100 kg per cubic metre
- Ceiling baffles and clouds, Both faces work, which is why suspended area outperforms the same area laid flat
-
At the receiver
Only after the first two, and only for what is left. 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.
- SoundBlanket mass loaded vinyl, STC 34, 8.4 kg per sq m
- Acoustic foam and BassBloc, 100 to 500 Hz
- Ceiling baffles and clouds, ASTM C423
Designers get colour, pattern and CNC options with the absorption figure attached to each. See how we work with interior designers.
04 / Climate and durability
Why the climate in Vienna changes the material, not the target
Vienna is cool and damp, with long heating seasons and cold external walls, and that narrows the material list before acoustics is 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 failure we design against here is condensation behind linings in older, poorly insulated stock.
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.
06 / Worth knowing
Six mistakes that turn into a second fit-out
-
Absorption on the office wall for a plant room problem
Enclose the machine, break the vibration path, then deal with what is left. Doing it in the other order costs more and achieves less.
-
Lagging a duct that is carrying the noise as breakout from the fan
Enclose the machine, break the vibration path, then deal with what is left. Doing it in the other order costs more and achieves less.
-
Ignoring structure borne vibration through the mounts
It sounds like a small detail until the room is finished and the complaint arrives.
-
Treating it as a generic Vienna job
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.
05 / Logistics
How material reaches a Vienna site
| 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 |
| Support | Drawings, build-ups, BOQ and material that arrives complete |
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.
Questions from Vienna projects
What makes HVAC, plant and machine noise control different in Vienna?
Mechanical ventilation with heat recovery in newer buildings, so duct-borne noise is the source. 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.
Where should the budget go first on a Vienna project?
At source. Enclosure, barrier or anti vibration mounts at the machine. In the path. Duct lining, attenuators and lagging on the first run out of the plant.
Do you have an office or installation team in Vienna?
No. We manufacture in India and supply into Vienna. We give you drawings, build-ups, a BOQ and material that arrives complete, and we will tell you plainly when a job needs a local contractor we cannot be.
How does material get to a Vienna site?
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 goes wrong most often on this kind of project?
Absorption on the office wall for a plant room problem. Lagging a duct that is carrying the noise as breakout from the fan.
What do you need from us to quote?
A plan, a section through the critical partition or ceiling, and what the room is for. From that we can give a build-up and a BOQ rather than a price per square foot.
