HVAC, plant and machine noise control in Spain
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 and multi-split systems dominate, with condensers in patios and 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 / The material
What this material is and where it earns its place in Spain
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 and multi-split systems dominate, with condensers in patios and light wells that act as reverberant shafts.
Work reaching us from Spain is mostly hotels and resorts, restaurants, apartments, offices, schools, clinics, studios.
- Sealed, air-conditioned rooms Once a room is closed up against the heat it stops leaking sound outward and starts building it up inside. Absorption has to be balanced, not maximised.
- Tile and terrazzo everywhere Hard floors and rendered walls are the standard build. They reflect almost everything, so absorption on the ceiling usually does more than anything you add at eye level.
- Season deadlines are real deadlines Coastal and resort work has to be finished before the season opens. We give honest dispatch and transit windows rather than optimistic ones, so the fit-out is not waiting on a container.
- 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 Spain.
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 Spain, split and multi-split systems dominate, with condensers in patios and 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
Wood wool acoustic panels
Wood fibre bound into a rigid board with an open texture. In Spain, churches, civic auditoriums and hotel function rooms are stone and plaster volumes with very long decay times.
On a cavity. Mounted on battens with an air gap, which is where the low mid performance comes from.
-
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 Spain, school buildings are concrete and tile with high ceilings and hard floors, and dining halls are the loudest rooms in the building.
Behind a fabric frame. Where the room has to look finished, absorber inside a frame rather than foam on show.
We would rather argue about the build-up at design stage than on site. See how we support architects.
03 / Local conditions
The Spain conditions that change the answer
- Sealed, air-conditioned rooms
Once a room is closed up against the heat it stops leaking sound outward and starts building it up inside. Absorption has to be balanced, not maximised.
- Tile and terrazzo everywhere
Hard floors and rendered walls are the standard build. They reflect almost everything, so absorption on the ceiling usually does more than anything you add at eye level.
- Season deadlines are real deadlines
Coastal and resort work has to be finished before the season opens. We give honest dispatch and transit windows rather than optimistic ones, so the fit-out is not waiting on a container.
- Late hours, homes above
Bars and restaurants run late underneath apartments. The complaint is almost always low frequency and footfall, which means mass and isolation, not foam.
- Plant and HVAC
Split and multi-split systems dominate, with condensers in patios and light wells that act as reverberant shafts.
04 / Room by room
Where the money goes on a Spain project
-
At source
Enclosure, barrier or anti vibration mounts at the machine. Once a room is closed up against the heat it stops leaking sound outward and starts building it up inside. Absorption has to be balanced, not maximised.
- SoundBlanket mass loaded vinyl, 2100 kg per cubic metre
- Wood wool acoustic panels, 20 mm
- Acoustic foam and BassBloc, 100 kg per cubic metre
-
In the path
Duct lining, attenuators and lagging on the first run out of the plant. Hard floors and rendered walls are the standard build. They reflect almost everything, so absorption on the ceiling usually does more than anything you add at eye level.
- SoundBlanket mass loaded vinyl, STC 30, 5.25 kg per sq m
- Wood wool acoustic panels, 400 kg per cubic metre
- Acoustic foam and BassBloc, 100 to 500 Hz
-
At the receiver
Only after the first two, and only for what is left. Coastal and resort work has to be finished before the season opens. We give honest dispatch and transit windows rather than optimistic ones, so the fit-out is not waiting on a container.
- SoundBlanket mass loaded vinyl, STC 34, 8.4 kg per sq m
- Wood wool acoustic panels, 0.30
- Acoustic foam and BassBloc, 0.85
Designers get colour, pattern and CNC options with the absorption figure attached to each. See how we work with interior designers.
04 / Climate and durability
Durability in Spain, before acoustics is discussed
Spain 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
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
Enclose the machine, break the vibration path, then deal with what is left. Doing it in the other order costs more and achieves less.
-
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 Spain job
Once a room is closed up against the heat it stops leaking sound outward and starts building it up inside. Absorption has to be balanced, not maximised.

Questions from Spain projects
What makes HVAC, plant and machine noise control different in Spain?
Split and multi-split systems dominate, with condensers in patios and light wells that act as reverberant shafts. Hard floors and rendered walls are the standard build. They reflect almost everything, so absorption on the ceiling usually does more than anything you add at eye level.
Where should the budget go first on a Spain 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 Spain?
No. We manufacture in India and supply into Spain. 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 Spain site?
ships from: Palwal, Haryana, India, arrives at: Valencia, Barcelona or Algeciras, then road 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.
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.
