HVAC, plant and machine noise control in Lisbon
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 in courtyards and light wells, plus seasonal heating in cold damp winters.
- 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 product
What this is, and what it changes in a Lisbon room
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 in courtyards and light wells, plus seasonal heating in cold damp winters.
Work reaching us from Lisbon is mostly hotel and short let conversions, apartments, restaurants, offices, clinics, studios.
- Conversions put beds either side of old walls A house divided into guest rooms turns internal partitions into separating walls overnight. Doors and corridors generate more complaints than the walls themselves.
- Timber floors, every floor Footfall from above is the single most common complaint we hear from this city. It is a floor problem, and treating the ceiling below rarely fixes it.
- Hills and narrow streets Access decides the delivery. Tell us the street and the stairwell and we break pallets down to what will actually get to the room.
- 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 Lisbon.
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 Lisbon, split units with condensers in courtyards and light wells, plus seasonal heating in cold damp winters.
Floor, floating. Membrane under a resilient layer and a floating deck, so impact energy is broken before it reaches the slab.
-
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 Lisbon, church buildings, civic auditoria and function rooms are stone volumes with very long decay.
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 Lisbon, school buildings are hard surfaced with high ceilings, and canteens are the loudest rooms.
Behind a fabric frame. Where the room has to look finished, absorber inside a frame rather than foam on show.
Architects working in Lisbon usually need the build-up before the product. We will draw the section and mark what does the work. See how we support architects.
03 / In this market
What the buildings in Lisbon do to the specification
- Conversions put beds either side of old walls
A house divided into guest rooms turns internal partitions into separating walls overnight. Doors and corridors generate more complaints than the walls themselves.
- Timber floors, every floor
Footfall from above is the single most common complaint we hear from this city. It is a floor problem, and treating the ceiling below rarely fixes it.
- Hills and narrow streets
Access decides the delivery. Tell us the street and the stairwell and we break pallets down to what will actually get to the room.
- Late districts under homes
Venues in the old districts operate directly beneath apartments. Low frequency containment is what keeps the operation trading.
- Plant and HVAC
Split units with condensers in courtyards and light wells, plus seasonal heating in cold damp winters.
04 / Room by room
Space by space, for Lisbon briefs
-
At source
Enclosure, barrier or anti vibration mounts at the machine. A house divided into guest rooms turns internal partitions into separating walls overnight. Doors and corridors generate more complaints than the walls themselves.
- 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
- Wood wool acoustic panels, 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. Footfall from above is the single most common complaint we hear from this city. It is a floor problem, and treating the ceiling below rarely fixes it.
- 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
- 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. Access decides the delivery. Tell us the street and the stairwell and we break pallets down to what will actually get to the room.
- Soundproofing materials, Mass, then decoupling, then cavity absorption, then sealing
- Wood wool acoustic panels, 0.30
- 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 / Durability
Why the climate in Lisbon changes the material, not the target
Lisbon 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.
On a Lisbon job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.

Six mistakes that turn into a second fit-out
-
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
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 Lisbon job
A house divided into guest rooms turns internal partitions into separating walls overnight. Doors and corridors generate more complaints than the walls themselves.
05 / Getting it there
How material reaches a Lisbon site
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Lisbon or Sines, then a short road run to site |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Lisbon or Sines |
| 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 Lisbon or Sines, then a short road run to site. Air freight for samples and urgent quantities.
Questions from Lisbon projects
What makes HVAC, plant and machine noise control different in Lisbon?
Split units with condensers in courtyards and light wells, plus seasonal heating in cold damp winters. A house divided into guest rooms turns internal partitions into separating walls overnight. Doors and corridors generate more complaints than the walls themselves.
Where should the budget go first on a Lisbon 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 Lisbon?
No. We manufacture in India and supply into Lisbon. 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 Lisbon site?
ships from: Palwal, Haryana, India, arrives at: Lisbon or Sines, 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
Tell us the room, we will tell you the 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.
