HVAC, plant and machine noise control in Czechia
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 in newer buildings and radiator heating in older stock, so duct noise is a newer problem than it looks.
- 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 material is and where it earns its place in Czechia
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 in newer buildings and radiator heating in older stock, so duct noise is a newer problem than it looks.
Work reaching us from Czechia is mostly production halls, plant rooms, offices, panel block apartments, schools, clinics.
- Panel block apartments Prefabricated concrete panel housing passes speech and footfall between flats through thin, well connected elements. Surface treatment does nothing here. Mass and a resilient break do.
- Industrial noise is a mass problem Compressors, presses and extraction plant are low frequency and structure-borne. We will tell you when absorption is the wrong purchase rather than sell it to you.
- Value is checked properly Czech buyers compare specifications line by line. That suits a manufacturer, because we can answer for what is actually in the product.
- 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 Czechia.
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 Czechia, mechanical ventilation in newer buildings and radiator heating in older stock, so duct noise is a newer problem than it looks.
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 Czechia, concert halls, church buildings and civic rooms are long-decay volumes in stone and plaster.
Floating floor. Resilient layer and deck, to break impact energy before it reaches the structure.
-
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 Czechia, school buildings are hard surfaced with long corridors, and gymnasiums double as assembly halls.
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 Czechia project, we can give you a section, a BOQ and the honest limits of each layer. See how we support architects.
03 / In this market
The Czechia conditions that change the answer
- Panel block apartments
Prefabricated concrete panel housing passes speech and footfall between flats through thin, well connected elements. Surface treatment does nothing here. Mass and a resilient break do.
- Industrial noise is a mass problem
Compressors, presses and extraction plant are low frequency and structure-borne. We will tell you when absorption is the wrong purchase rather than sell it to you.
- Value is checked properly
Czech buyers compare specifications line by line. That suits a manufacturer, because we can answer for what is actually in the product.
- Landlocked, so plan the inland leg
Hamburg then rail and road. We quote the sea leg and the inland leg separately so the programme is built on real dates.
- Plant and HVAC
Mechanical ventilation in newer buildings and radiator heating in older stock, so duct noise is a newer problem than it looks.
04 / Room by room
Where the money goes on a Czechia project
-
At source
Enclosure, barrier or anti vibration mounts at the machine. Prefabricated concrete panel housing passes speech and footfall between flats through thin, well connected elements. Surface treatment does nothing here. Mass and a resilient break do.
- 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. Compressors, presses and extraction plant are low frequency and structure-borne. We will tell you when absorption is the wrong purchase rather than sell it to you.
- 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. Czech buyers compare specifications line by line. That suits a manufacturer, because we can answer for what is actually in the product.
- 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
The Czechia climate decides the material list
Czechia 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 Czechia job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.
06 / Before you buy
Six mistakes that turn into a second fit-out
-
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
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
This is the one that comes back as a second fit-out rather than a snag.
-
Treating it as a generic Czechia job
Prefabricated concrete panel housing passes speech and footfall between flats through thin, well connected elements. Surface treatment does nothing here. Mass and a resilient break do.
05 / Route to site
What the route into Czechia actually looks like
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Hamburg, then rail and road inland |
| Dispatch | 4 to 7 working days |
| Freight | Sea via 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 Hamburg, then rail and road inland. Air freight for samples and urgent quantities.
Questions from Czechia projects
What makes HVAC, plant and machine noise control different in Czechia?
Mechanical ventilation in newer buildings and radiator heating in older stock, so duct noise is a newer problem than it looks. Prefabricated concrete panel housing passes speech and footfall between flats through thin, well connected elements. Surface treatment does nothing here. Mass and a resilient break do.
Where should the budget go first on a Czechia 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 Czechia?
No. We manufacture in India and supply into Czechia. 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 Czechia site?
ships from: Palwal, Haryana, India, arrives at: 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.
