HVAC, plant and machine noise control in Germany
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 is standard in newer stock, so duct-borne noise and terminal unit noise are the sources rather than open windows.
- 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 Germany 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 is standard in newer stock, so duct-borne noise and terminal unit noise are the sources rather than open windows.
Work reaching us from Germany is mostly offices, studios, clubs, hotels, schools, clinics, industrial plant rooms.
- Two building stocks Altbau apartments with timber floors pass noise between homes. Post-war concrete holds it in and rings. The same room needs a different answer depending on which one you are in.
- Specified acoustics Most German jobs arrive with an acoustician already involved. Send us the target values and we will tell you which build-up gets there, and which one will not.
- Container quantities Fit-outs across several floors or sites are cheaper by container. We quote full loads and stage deliveries against your programme.
- 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 Germany.
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 Germany, mechanical ventilation with heat recovery is standard in newer stock, so duct-borne noise and terminal unit noise are the sources rather than open windows.
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 Germany, concert halls, church buildings and civic Saal spaces are long-reverberation rooms where any intervention has to be reversible and visually disciplined.
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 Germany, school and university buildings are built to a high thermal standard with hard, cleanable surfaces. Speech clarity in classrooms and long corridors is where the acoustic budget goes.
Corner loading. Low frequency energy collects in corners, so absorber in the corners does more than the same area spread across a wall.
For a Germany practice, the useful thing is a detail you can put in a drawing set, not a brochure. See how we support architects.
03 / In this market
What decides the build-up in Germany
- Two building stocks
Altbau apartments with timber floors pass noise between homes. Post-war concrete holds it in and rings. The same room needs a different answer depending on which one you are in.
- Specified acoustics
Most German jobs arrive with an acoustician already involved. Send us the target values and we will tell you which build-up gets there, and which one will not.
- Container quantities
Fit-outs across several floors or sites are cheaper by container. We quote full loads and stage deliveries against your programme.
- Winter build programmes
Sealed, insulated rooms sound dead in the wrong way. Absorption has to be balanced, not maximised, once the envelope is tight.
- Plant and HVAC
Mechanical ventilation with heat recovery is standard in newer stock, so duct-borne noise and terminal unit noise are the sources rather than open windows.
04 / Room by room
Space by space, for Germany briefs
-
At source
Enclosure, barrier or anti vibration mounts at the machine. Altbau apartments with timber floors pass noise between homes. Post-war concrete holds it in and rings. The same room needs a different answer depending on which one you are in.
- 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. Most German jobs arrive with an acoustician already involved. Send us the target values and we will tell you which build-up gets there, and which one will not.
- 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. Fit-outs across several floors or sites are cheaper by container. We quote full loads and stage deliveries against your programme.
- 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
If the visual is fixed and the room still has to perform, that is a solvable problem and a conversation worth having early. See how we work with interior designers.
04 / Climate and durability
The Germany climate decides the material list
Germany 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.
Where a consultant is already engaged on a Germany project, we supply to their specification and send the test reports rather than describing them. More on 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
Small on the drawing, expensive on site, and almost always found after handover.
-
Treating it as a generic Germany job
Altbau apartments with timber floors pass noise between homes. Post-war concrete holds it in and rings. The same room needs a different answer depending on which one you are in.

Questions from Germany projects
What makes HVAC, plant and machine noise control different in Germany?
Mechanical ventilation with heat recovery is standard in newer stock, so duct-borne noise and terminal unit noise are the sources rather than open windows. Altbau apartments with timber floors pass noise between homes. Post-war concrete holds it in and rings. The same room needs a different answer depending on which one you are in.
Where should the budget go first on a Germany 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 Germany?
No. We manufacture in India and supply into Germany. 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 Germany site?
ships from: Palwal, Haryana, India, arrives at: Hamburg or Bremerhaven, then road to site, 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.
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
Tell us the room, we will tell you the build-up
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.
