HVAC, plant and machine noise control in Athens
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. Split units with condensers on balconies and in light wells that act as reverberant shafts.
- 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 / What it is
The product, described honestly, for a Athens brief
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.
Split units with condensers on balconies and in light wells that act as reverberant shafts.
Work reaching us from Athens is mostly apartment blocks, hotels and short lets, restaurants and roof terraces, offices, clinics, schools.
- Concrete blocks, hard interiors The structure carries mass, so airborne transfer between flats is rarely the issue. Marble and tile making the room ring is.
- Impact through slabs Hard flooring over concrete passes footfall straight down. A resilient underlay before the finish is the fix, not a treatment below.
- Roof terraces and late trading Venues operate above and beside homes through a long season, so containment is what protects the operation.
- 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 Athens.
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 Athens, split units with condensers on balconies and in light wells that act as reverberant shafts.
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
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 Athens, church buildings, civic halls and open air venues are hard volumes with long decay.
Behind a fabric frame. Where the room has to look finished, absorber inside a frame rather than foam on show.
-
Layer 3
Ceiling baffles and clouds
PET felt suspended from the soffit, vertically as baffles or horizontally as clouds. In Athens, school buildings are concrete and tile with high ceilings and courtyards that amplify break time noise.
Mixed with services. Set out around ducts, trays and lighting rather than fighting them, coordinated from your reflected ceiling plan.
For a Athens practice, the useful thing is a detail you can put in a drawing set, not a brochure. See how we support architects.
03 / On the ground
The Athens conditions that change the answer
- Concrete blocks, hard interiors
The structure carries mass, so airborne transfer between flats is rarely the issue. Marble and tile making the room ring is.
- Impact through slabs
Hard flooring over concrete passes footfall straight down. A resilient underlay before the finish is the fix, not a treatment below.
- Roof terraces and late trading
Venues operate above and beside homes through a long season, so containment is what protects the operation.
- Piraeus is next to the city
Direct sea into the port beside Athens keeps landed cost and dates both predictable.
- Plant and HVAC
Split units with condensers on balconies and in light wells that act as reverberant shafts.
04 / Room by room
Room by room, on a typical Athens job
-
At source
Enclosure, barrier or anti vibration mounts at the machine. The structure carries mass, so airborne transfer between flats is rarely the issue. Marble and tile making the room ring is.
- Soundproofing materials, 2100 kg per cubic metre. 2.5 mm STC 30 at 5.25 kg per sq m, 4 mm STC 34 at 8.4, 6 mm at 12.6
- 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. Hard flooring over concrete passes footfall straight down. A resilient underlay before the finish is the fix, not a treatment below.
- Soundproofing materials, 1800 x 900 x 20 mm, 100 kg per cubic metre, NRC 0.85
- 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. Venues operate above and beside homes through a long season, so containment is what protects the operation.
- Soundproofing materials, Mass, then decoupling, then cavity absorption, then sealing
- Acoustic foam and BassBloc, 100 to 500 Hz
- Ceiling baffles and clouds, ASTM C423
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 and durability
The Athens climate decides the material list
Athens is hot dry summers and mild wet winters, and that narrows the material list before acoustics is discussed.
The swing between a dry summer and a wet winter moves timber. PET felt is dimensionally stable across that swing; slat panels want a stable substrate and a ventilated fixing.
The failure we design against here is seasonal movement in timber and winter damp in unheated stock.
Consultants get the raw data, not a sales sheet. That is the whole of our side of the job, and it is set out under 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
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
It sounds like a small detail until the room is finished and the complaint arrives.
-
Treating it as a generic Athens job
The structure carries mass, so airborne transfer between flats is rarely the issue. Marble and tile making the room ring is.
05 / Logistics
What the route into Athens actually looks like
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Piraeus, then a short road run to site |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Piraeus |
| 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 Piraeus, then a short road run to site. Air freight for samples and urgent quantities.
Questions from Athens projects
What makes HVAC, plant and machine noise control different in Athens?
Split units with condensers on balconies and in light wells that act as reverberant shafts. The structure carries mass, so airborne transfer between flats is rarely the issue. Marble and tile making the room ring is.
Where should the budget go first on a Athens 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 Athens?
No. We manufacture in India and supply into Athens. 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 Athens site?
ships from: Palwal, Haryana, India, arrives at: Piraeus, then a short road run to site, 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
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.
