HVAC, plant and machine noise control in Serbia
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 and light wells.
- 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
01 / The material
What this material is and where it earns its place in Serbia
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 and light wells.
Work reaching us from Serbia is mostly manufacturing plants, offices and service centres, panel block housing, hotels, schools, hospitals.
- Landlocked, through a neighbour Two ports to choose from and a border to cross. We quote each leg separately so the programme runs on real dates.
- Manufacturing and plant Continuous machine noise where enclosure and mass do the work rather than absorption on a wall.
- Panel block housing Prefabricated concrete blocks pass speech and footfall between flats. Surface treatment does nothing here.
- 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 Serbia.
02 / The build-up
The build-up, layer by layer
-
Layer 1
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 Serbia, district heating and split units, with condensers in courtyards and light wells.
Resilient bar. Where a full independent leaf will not fit. Effective, and very easy to short circuit with one wrong screw.
-
Layer 2
Wood wool acoustic panels
Wood fibre bound into a rigid board with an open texture. In Serbia, church buildings, civic halls and auditoria are hard volumes with long reverberation.
On a cavity. Mounted on battens with an air gap, which is where the low mid performance comes from.
-
Layer 3
Ceiling baffles and clouds
PET felt suspended from the soffit, vertically as baffles or horizontally as clouds. In Serbia, school buildings are hard surfaced with long corridors and gymnasiums doubling as halls.
Horizontal clouds. Flat rafts over the occupied zone, which also reflect early speech energy back down where it helps.
We would rather argue about the build-up at design stage than on site. See how we support architects.
03 / On the ground
What decides the build-up in Serbia
- Landlocked, through a neighbour
Two ports to choose from and a border to cross. We quote each leg separately so the programme runs on real dates.
- Manufacturing and plant
Continuous machine noise where enclosure and mass do the work rather than absorption on a wall.
- Panel block housing
Prefabricated concrete blocks pass speech and footfall between flats. Surface treatment does nothing here.
- Belgrade conversions
Older buildings turned into offices and hospitality, with tall rooms and hard plaster that hold sound too long.
- Plant and HVAC
District heating and split units, with condensers in courtyards and light wells.
04 / Room by room
What each space in a Serbia project needs
-
At source
Enclosure, barrier or anti vibration mounts at the machine. Two ports to choose from and a border to cross. We quote each leg separately so the programme runs on real dates.
- 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
- 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. Continuous machine noise where enclosure and mass do the work rather than absorption on a wall.
- SoundBlanket mass loaded vinyl, STC 30, 5.25 kg per sq m
- Soundproofing materials, Mass, then decoupling, then cavity absorption, then sealing
- 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. Prefabricated concrete blocks pass speech and footfall between flats. Surface treatment does nothing here.
- SoundBlanket mass loaded vinyl, STC 34, 8.4 kg per sq m
- Soundproofing materials, ASTM E90 for the barrier, ASTM C423 for the absorber
- Ceiling baffles and clouds, ASTM C423
Designers get colour, pattern and CNC options with the absorption figure attached to each. See how we work with interior designers.
04 / Conditions
What the Serbia climate rules in and rules out
Serbia is cold winters and warm summers, with a wide annual temperature range, and that narrows the material list before acoustics is discussed.
A wide annual swing stresses adhesive fixings and moves timber. Mechanical fixing beats adhesive alone, and PET felt is stable across the range.
The failure we design against here is adhesive failure and timber movement across the annual swing.
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 / Straight talk
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
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
It sounds like a small detail until the room is finished and the complaint arrives.
-
Treating it as a generic Serbia job
Two ports to choose from and a border to cross. We quote each leg separately so the programme runs on real dates.
05 / Logistics
What the route into Serbia actually looks like
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Thessaloniki or Koper, then road across the border |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Thessaloniki or Koper, then road |
| 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 Thessaloniki or Koper, then road across the border. Air freight for samples and urgent quantities.
Questions from Serbia projects
What makes HVAC, plant and machine noise control different in Serbia?
District heating and split units, with condensers in courtyards and light wells. Two ports to choose from and a border to cross. We quote each leg separately so the programme runs on real dates.
Where should the budget go first on a Serbia 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 Serbia?
No. We manufacture in India and supply into Serbia. 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 Serbia site?
ships from: Palwal, Haryana, India, arrives at: Thessaloniki or Koper, then road across the border, 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
Send a plan and a section, get a real 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.
