HVAC, plant and machine noise control in Frankfurt
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.

What this material is and where it earns its place in Frankfurt
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 Frankfurt is mostly tower office floors, trading and call floors, data and plant rooms, hotels, studios, clinics.
- Towers full of glass Full height glazing, raised floors and exposed slabs give sound nothing to land on. The ceiling has to do most of the work, and it has to do it without breaking the design.
- Speech privacy is a business requirement On banking and trading floors the issue is not comfort, it is who can hear what. Absorption plus masking beats absorption alone every time.
- Plant rooms and equipment halls Generators, chillers and cooling plant sit close to occupied space and close to neighbours. Mass and a resilient break do more than any lining.
- 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 Frankfurt.
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 Frankfurt, 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.
Wall, decoupled. Independent stud, membrane between the boards, cavity absorption, two boards. The membrane is one part of a system, never the whole answer.
-
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 Frankfurt, 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 Frankfurt, 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.
We would rather argue about the build-up at design stage than on site. See how we support architects.
03 / In this market
What the buildings in Frankfurt do to the specification
- Towers full of glass
Full height glazing, raised floors and exposed slabs give sound nothing to land on. The ceiling has to do most of the work, and it has to do it without breaking the design.
- Speech privacy is a business requirement
On banking and trading floors the issue is not comfort, it is who can hear what. Absorption plus masking beats absorption alone every time.
- Plant rooms and equipment halls
Generators, chillers and cooling plant sit close to occupied space and close to neighbours. Mass and a resilient break do more than any lining.
- Trade fair and hotel programmes
Messe dates do not move. We give honest dispatch and transit windows so a fit-out is not sitting waiting on a container that will not land in time.
- 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
Where the money goes on a Frankfurt project
-
At source
Enclosure, barrier or anti vibration mounts at the machine. Full height glazing, raised floors and exposed slabs give sound nothing to land on. The ceiling has to do most of the work, and it has to do it without breaking the design.
- SoundBlanket mass loaded vinyl, 2100 kg per cubic metre
- Wood wool acoustic panels, 20 mm
- Acoustic foam and BassBloc, 100 kg per cubic metre
-
In the path
Duct lining, attenuators and lagging on the first run out of the plant. On banking and trading floors the issue is not comfort, it is who can hear what. Absorption plus masking beats absorption alone every time.
- SoundBlanket mass loaded vinyl, STC 30, 5.25 kg per sq m
- Wood wool acoustic panels, 400 kg per cubic metre
- Acoustic foam and BassBloc, 100 to 500 Hz
-
At the receiver
Only after the first two, and only for what is left. Generators, chillers and cooling plant sit close to occupied space and close to neighbours. Mass and a resilient break do more than any lining.
- SoundBlanket mass loaded vinyl, STC 34, 8.4 kg per sq m
- Wood wool acoustic panels, 0.30
- Acoustic foam and BassBloc, 0.85
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
Durability in Frankfurt, before acoustics is discussed
Frankfurt 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.
On a Frankfurt job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.
06 / Worth knowing
What we watch go wrong on jobs like this
-
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
Plant noise treated as a room problem is the most reliable way to spend a budget and change nothing anyone can hear.
-
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 Frankfurt job
Full height glazing, raised floors and exposed slabs give sound nothing to land on. The ceiling has to do most of the work, and it has to do it without breaking the design.
05 / Supply

Questions from Frankfurt projects
What makes HVAC, plant and machine noise control different in Frankfurt?
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. Full height glazing, raised floors and exposed slabs give sound nothing to land on. The ceiling has to do most of the work, and it has to do it without breaking the design.
Where should the budget go first on a Frankfurt 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 Frankfurt?
No. We manufacture in India and supply into Frankfurt. 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 Frankfurt site?
ships from: Palwal, Haryana, India, arrives at: Hamburg or Rotterdam by sea, or Frankfurt airport when the date demands it, 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.
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.
