HVAC, plant and machine noise control in Cuba
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 and generator sets where available, with plant close to occupied rooms.
- 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.

- From a plan and a section, within 48 hours
01 / The material
What you are buying, and what it fixes in Cuba
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 and generator sets where available, with plant close to occupied rooms.
Work reaching us from Cuba is mostly hotels and restoration projects, theatres and halls, offices, clinics, schools.
- Paperwork is part of the lead time Import formalities take real time here. We prepare the documentation package before shipping rather than after, and we quote the full window.
- Heritage buildings under restoration Tall rooms with hard plaster and timber floors, where the structure stays and everything has to be done internally and shallow.
- Salt air and humidity PET felt does not absorb moisture, rot or feed mould, which matters on a Caribbean coast where mineral products fail quickly.
- 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 Cuba.
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 Cuba, split units and generator sets where available, with plant close to occupied rooms.
Duct and plant wrap. Membrane wrapped over the duct with a decoupling layer beneath, sealed at every lap.
-
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 Cuba, theatres, church buildings and cultural centres are masonry volumes with very long decay.
Floating floor. Resilient layer and deck, to break impact energy before it reaches the structure.
-
Layer 3
Wood wool acoustic panels
Wood fibre bound into a rigid board with an open texture. In Cuba, classrooms are hard and naturally ventilated with high ceilings and open circulation.
On a cavity. Mounted on battens with an air gap, which is where the low mid performance comes from.
If you are specifying for a Cuba project, we can give you a section, a BOQ and the honest limits of each layer. See how we support architects.
03 / In this market
What the buildings in Cuba do to the specification
- Paperwork is part of the lead time
Import formalities take real time here. We prepare the documentation package before shipping rather than after, and we quote the full window.
- Heritage buildings under restoration
Tall rooms with hard plaster and timber floors, where the structure stays and everything has to be done internally and shallow.
- Salt air and humidity
PET felt does not absorb moisture, rot or feed mould, which matters on a Caribbean coast where mineral products fail quickly.
- Theatres and assembly halls
Large historic rooms where speech intelligibility fails long before anyone calls the room echoey.
- Plant and HVAC
Split units and generator sets where available, with plant close to occupied rooms.
04 / Room by room
Room by room, on a typical Cuba job
-
At source
Enclosure, barrier or anti vibration mounts at the machine. Import formalities take real time here. We prepare the documentation package before shipping rather than after, and we quote the full window.
- 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
- 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. Tall rooms with hard plaster and timber floors, where the structure stays and everything has to be done internally and shallow.
- SoundBlanket mass loaded vinyl, STC 30, 5.25 kg per sq m
- Soundproofing materials, Mass, then decoupling, then cavity absorption, then sealing
- Acoustic foam and BassBloc, 100 to 500 Hz
-
At the receiver
Only after the first two, and only for what is left. PET felt does not absorb moisture, rot or feed mould, which matters on a Caribbean coast where mineral products fail quickly.
- SoundBlanket mass loaded vinyl, STC 34, 8.4 kg per sq m
- Soundproofing materials, ASTM E90 for the barrier, ASTM C423 for the absorber
- Acoustic foam and BassBloc, 0.85
If the visual is fixed and the room still has to perform, that is a solvable problem and a conversation worth having early. See how we work with interior designers.
04 / Climate
Durability in Cuba, before acoustics is discussed
Cuba is hot summers, mild winters and a distinct wet season, and that narrows the material list before acoustics is discussed.
PET felt handles the wet months without absorbing moisture or feeding mould. Timber and wood wool want a ventilated cavity and a stable indoor RH.
The failure we design against here is wet-season humidity behind linings.
On a Cuba job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.
06 / Worth knowing
What we watch go wrong on jobs like this
-
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
This is the one that comes back as a second fit-out rather than a snag.
-
Treating it as a generic Cuba job

05 / Route to site
What the route into Cuba actually looks like
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Mariel, then road to site |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Mariel |
| Support | Drawings, build-ups, BOQ and material that arrives complete |
Standard items dispatch in 4 to 7 working days. The sea leg from India is long, so plan the full door to door window into the programme. We give real dates, not optimistic ones.
Sea freight into Mariel, then road to site. Air freight for samples where it is practical.
Questions from Cuba projects
What makes HVAC, plant and machine noise control different in Cuba?
Split units and generator sets where available, with plant close to occupied rooms. Import formalities take real time here. We prepare the documentation package before shipping rather than after, and we quote the full window.
Where should the budget go first on a Cuba 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 Cuba?
No. We manufacture in India and supply into Cuba. 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 Cuba site?
ships from: Palwal, Haryana, India, arrives at: Mariel, then road to site, dispatch: 4 to 7 working days. Standard items dispatch in 4 to 7 working days. The sea leg from India is long, so plan the full door to door window into the programme. We give real dates, not optimistic ones.
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
One drawing gets you a proper answer. Build-up, quantities, a delivered date, and an honest note on anything we think is the wrong approach.
