HVAC, plant and machine noise control in Austria
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.
- Quote
- From a plan and a section, within 48 hours

The product, described honestly, for a Austria brief
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 Austria is mostly apartments, alpine hotels, offices, schools, clinics, studios, timber buildings.
- Landlocked, so plan the inland leg Koper is the shorter route from India, Hamburg the more frequent one. Either way there is rail and road after the port, and we build that into the date rather than quoting you a port arrival.
- Timber construction is growing Cross laminated and timber frame buildings are light. Light means low frequency passes easily, so the answer is added mass and a resilient break, not more absorption.
- Resort work runs to an opening date Alpine hotel refurbishment happens in a short window between seasons. Real dispatch and transit dates matter more than a slightly better price.
- 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 Austria.
02 / The build-up
How the layers stack, from the structure inwards
-
Layer 1
SoundBlanket mass loaded vinyl
A limp, high density sheet that adds mass to a partition, floor or duct without adding depth. In Austria, 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
Wood wool acoustic panels
Wood fibre bound into a rigid board with an open texture. In Austria, concert halls, church buildings and civic rooms are long-reverberation volumes where any intervention must be reversible.
On a cavity. Mounted on battens with an air gap, which is where the low mid performance comes from.
-
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 Austria, 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.
We would rather argue about the build-up at design stage than on site. See how we support architects.
03 / On the ground
The Austria conditions that change the answer
- Landlocked, so plan the inland leg
Koper is the shorter route from India, Hamburg the more frequent one. Either way there is rail and road after the port, and we build that into the date rather than quoting you a port arrival.
- Timber construction is growing
Cross laminated and timber frame buildings are light. Light means low frequency passes easily, so the answer is added mass and a resilient break, not more absorption.
- Resort work runs to an opening date
Alpine hotel refurbishment happens in a short window between seasons. Real dispatch and transit dates matter more than a slightly better price.
- Numbers before materials
Send the target values and the build-up. We will tell you what our material reaches and where it will not get you there, in writing, before you commit.

04 / Room by room
Where the money goes on a Austria project
-
At source
Enclosure, barrier or anti vibration mounts at the machine. Koper is the shorter route from India, Hamburg the more frequent one. Either way there is rail and road after the port, and we build that into the date rather than quoting you a port arrival.
- SoundBlanket mass loaded vinyl, 2100 kg per cubic metre
- Soundproofing materials, 1800 x 900 x 20 mm, 100 kg per cubic metre, NRC 0.85
- Wood wool acoustic panels, 400 kg per cubic metre
-
In the path
Duct lining, attenuators and lagging on the first run out of the plant. Cross laminated and timber frame buildings are light. Light means low frequency passes easily, so the answer is added mass and a resilient break, not more absorption.
- SoundBlanket mass loaded vinyl, STC 30, 5.25 kg per sq m
- Soundproofing materials, Mass, then decoupling, then cavity absorption, then sealing
- Wood wool acoustic panels, 0.30
-
At the receiver
Only after the first two, and only for what is left. Alpine hotel refurbishment happens in a short window between seasons. Real dispatch and transit dates matter more than a slightly better price.
- SoundBlanket mass loaded vinyl, STC 34, 8.4 kg per sq m
- Soundproofing materials, ASTM E90 for the barrier, ASTM C423 for the absorber
- Wood wool acoustic panels, ASTM C-423 and EN ISO 354
Interior designers tend to arrive with the look already decided. We will tell you which finish gets there without losing the acoustics. See how we work with interior designers.
04 / Climate and durability
Why the climate in Austria changes the material, not the target
Austria 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.

What we watch go wrong on jobs like this
-
Absorption on the office wall for a plant room problem
Noise with a source is fixed at the source. Treating the receiving room is the expensive way to get a small result.
-
Lagging a duct that is carrying the noise as breakout from the fan
Noise with a source is fixed at the source. Treating the receiving room is the expensive way to get a small result.
-
Ignoring structure borne vibration through the mounts
This is the one that comes back as a second fit-out rather than a snag.
-
Treating it as a generic Austria job
Koper is the shorter route from India, Hamburg the more frequent one. Either way there is rail and road after the port, and we build that into the date rather than quoting you a port arrival.

Questions from Austria projects
What makes HVAC, plant and machine noise control different in Austria?
Mechanical ventilation with heat recovery in newer buildings, so duct-borne noise is the source. Koper is the shorter route from India, Hamburg the more frequent one. Either way there is rail and road after the port, and we build that into the date rather than quoting you a port arrival.
Where should the budget go first on a Austria 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 Austria?
No. We manufacture in India and supply into Austria. 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 Austria site?
ships from: Palwal, Haryana, India, arrives at: Koper or Hamburg, then rail and road inland, 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.
Next step
Drawings in, BOQ and a delivered date out
We quote from drawings, not from a square foot rate. Send a plan and the section through the critical wall or ceiling and you will get something you can actually build from.
