HVAC, plant and machine noise control in Madrid
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.

The product, described honestly, for a Madrid 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 and multi-split systems dominate, with condensers in patios and light wells that act as reverberant shafts.
Work reaching us from Madrid is mostly ensanche apartments, Castellana office floors, restaurants, hotels, clinics, studios, schools.
- Closed up against the heat Once a room is sealed and air conditioned it stops leaking sound outward and starts building it up inside. Absorption has to be balanced, not maximised.
- Ensanche blocks share everything The classic Madrid block stacks flats around a central patio with shared walls and slabs. Footfall and speech move between homes, which is a mass and isolation problem, not a panel problem.
- Castellana floors have nothing soft Tower and corporate floors run glass to glass with raised floors and exposed slabs. Speech carries because there is nowhere for it to land, so the ceiling has to do the work.
- 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 Madrid.
02 / The build-up
What goes where, from the structure in
-
Layer 1
Wood wool acoustic panels
Wood fibre bound into a rigid board with an open texture. In Madrid, split and multi-split systems dominate, with condensers in patios and light wells that act as reverberant shafts.
Direct fix. Mechanically fixed to the soffit or wall. Durable and simple.
-
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 Madrid, churches, civic auditoriums and hotel function rooms are stone and plaster volumes with very long decay times.
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 Madrid, school buildings are concrete and tile with high ceilings and hard floors, and dining halls are the loudest rooms in the building.
Vertical baffles. Hung on edge in rows. Both faces absorb, so coverage figures based on plan area understate them.
Architects working in Madrid 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 decides the build-up in Madrid
- Closed up against the heat
Once a room is sealed and air conditioned it stops leaking sound outward and starts building it up inside. Absorption has to be balanced, not maximised.
- Ensanche blocks share everything
The classic Madrid block stacks flats around a central patio with shared walls and slabs. Footfall and speech move between homes, which is a mass and isolation problem, not a panel problem.
- Castellana floors have nothing soft
Tower and corporate floors run glass to glass with raised floors and exposed slabs. Speech carries because there is nowhere for it to land, so the ceiling has to do the work.
- A city that eats and drinks late
Bars and restaurants run long hours directly under apartments. The complaint is almost always low frequency and footfall, and it arrives fast.
- 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
What each space in a Madrid project needs
-
At source
Enclosure, barrier or anti vibration mounts at the machine. Once a room is sealed and air conditioned it stops leaking sound outward and starts building it up inside. Absorption has to be balanced, not maximised.
- 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. The classic Madrid block stacks flats around a central patio with shared walls and slabs. Footfall and speech move between homes, which is a mass and isolation problem, not a panel problem.
- 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. Tower and corporate floors run glass to glass with raised floors and exposed slabs. Speech carries because there is nowhere for it to land, so the ceiling has to do the work.
- 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
What the Madrid climate rules in and rules out
Madrid 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.
Where a consultant is already engaged on a Madrid project, we supply to their specification and send the test reports rather than describing them. 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
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
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
This is the one that comes back as a second fit-out rather than a snag.
-
Treating it as a generic Madrid job
Once a room is sealed and air conditioned it stops leaking sound outward and starts building it up inside. Absorption has to be balanced, not maximised.
05 / Getting it there
How material reaches a Madrid site
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Valencia or Barcelona, then road inland to Madrid |
| Dispatch | 4 to 7 working days |
| Freight | Sea, then road inland |
| 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 Valencia or Barcelona, then road inland to Madrid. Air freight for samples and urgent quantities.
Questions from Madrid projects
What makes HVAC, plant and machine noise control different in Madrid?
Split and multi-split systems dominate, with condensers in patios and light wells that act as reverberant shafts. The classic Madrid block stacks flats around a central patio with shared walls and slabs. Footfall and speech move between homes, which is a mass and isolation problem, not a panel problem.
Where should the budget go first on a Madrid 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 Madrid?
No. We manufacture in India and supply into Madrid. 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 Madrid site?
ships from: Palwal, Haryana, India, arrives at: Valencia or Barcelona, then road inland to Madrid, 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.
