HVAC, plant and machine noise control in Hungary
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. District heating and split units, with condensers in courtyards that reflect noise back into flats.
- 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 Hungary
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.
District heating and split units, with condensers in courtyards that reflect noise back into flats.
Work reaching us from Hungary is mostly automotive plants, offices and service centres, hotels, panel block housing, schools, hospitals.
- Landlocked, so plan the inland leg Koper then rail and road. We quote the sea leg and the inland leg separately so the programme runs on real dates.
- Automotive plant noise Presses, robots and conveyors are low frequency and structure-borne. Enclosure at the source rather than absorption on a far wall.
- Panel block housing Prefabricated concrete passes speech and footfall between flats through thin connected elements. Mass is the only reliable answer.
- 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 Hungary.
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 Hungary, district heating and split units, with condensers in courtyards that reflect noise back into flats.
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 Hungary, church buildings, concert halls and civic rooms are stone and plaster volumes with long decay.
With a porous backing. Board over mineral backing where the room needs more than the board alone gives.
-
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 Hungary, school buildings are hard surfaced with long corridors and gymnasiums serving as halls.
Behind a fabric frame. Where the room has to look finished, absorber inside a frame rather than foam on show.
For a Hungary 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 the buildings in Hungary do to the specification
- Landlocked, so plan the inland leg
Koper then rail and road. We quote the sea leg and the inland leg separately so the programme runs on real dates.
- Automotive plant noise
Presses, robots and conveyors are low frequency and structure-borne. Enclosure at the source rather than absorption on a far wall.
- Panel block housing
Prefabricated concrete passes speech and footfall between flats through thin connected elements. Mass is the only reliable answer.
- Budapest conversions
Old buildings turned into offices and hotels, with tall rooms and hard plaster that hold sound far too long.
- Plant and HVAC
District heating and split units, with condensers in courtyards that reflect noise back into flats.

Where the money goes on a Hungary project
-
At source
Enclosure, barrier or anti vibration mounts at the machine. Koper then rail and road. We quote the sea leg and the inland leg separately so the programme runs on real dates.
- SoundBlanket mass loaded vinyl, 2100 kg per cubic metre

-
In the path
Duct lining, attenuators and lagging on the first run out of the plant. Presses, robots and conveyors are low frequency and structure-borne. Enclosure at the source rather than absorption on a far wall.
- 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. Prefabricated concrete passes speech and footfall between flats through thin connected elements. Mass is the only reliable answer.
- 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 Hungary climate decides the material list
Hungary 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.
If a consultant has set the target, we will quote against their figures rather than ours, and stay out of the scope they own. More on working with acoustic consultants.
06 / Before you buy
The six errors that cost the most
-
Absorption on the office wall for a plant room problem
Plant noise treated as a room problem is the most reliable way to spend a budget and change nothing anyone can hear.
-
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 Hungary job
Koper then rail and road. We quote the sea leg and the inland leg separately so the programme runs on real dates.
05 / Supply
How material reaches a Hungary site
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Koper, then rail and road inland |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Koper, then rail |
| 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, then rail and road inland. Air freight for samples and urgent quantities.
Questions from Hungary projects
What makes HVAC, plant and machine noise control different in Hungary?
District heating and split units, with condensers in courtyards that reflect noise back into flats. Koper then rail and road. We quote the sea leg and the inland leg separately so the programme runs on real dates.
Where should the budget go first on a Hungary 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 Hungary?
No. We manufacture in India and supply into Hungary. 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 Hungary site?
ships from: Palwal, Haryana, India, arrives at: Koper, 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.

Send what you have. We will give you a layer by layer build-up, a bill of quantities and a date material lands, and we will flag anything in the brief that will not achieve what you want.
