For projects in Cuba
School and classroom acoustics in Cuba
Hard floors, bare walls and long corridors that amplify everything. Children with developing language, and anyone with a hearing difficulty, lose more from a live classroom than adults do, which is why intelligibility is the target rather than quiet. Classrooms are hard and naturally ventilated with high ceilings and open circulation.
- Classroom RT
- A number, set against room volume, achieved mostly at the ceiling.
- Corridor spill
- Long hard circulation feeds every room off it. Treating the corridor helps every classroom at once.
- Halls and gyms
- Dual use rooms carrying speech, music and sport, where durability decides the product.

01 / What it is
The material, and what it actually does on a Cuba job
Hard floors, bare walls and long corridors that amplify everything. Children with developing language, and anyone with a hearing difficulty, lose more from a live classroom than adults do, which is why intelligibility is the target rather than quiet.
Classrooms are hard and naturally ventilated with high ceilings and open circulation.
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.
- Classroom RT A number, set against room volume, achieved mostly at the ceiling.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for school acoustics are on the main product page. This page covers what that means for a project in Cuba.
02 / The build-up
What goes where, from the structure in
-
Layer 1
Ceiling baffles and clouds
PET felt suspended from the soffit, vertically as baffles or horizontally as clouds. In Cuba, split units and generator sets where available, with plant close to occupied rooms.
Horizontal clouds. Flat rafts over the occupied zone, which also reflect early speech energy back down where it helps.
-
Layer 2
Acoustic panels
The full absorber range rather than one product: plain PET felt, printed felt, grooved panels and fabric finishes, chosen by how the room is used and how it has to look. In Cuba, theatres, church buildings and cultural centres are masonry volumes with very long decay.
Mixed finish. Plain felt where it is out of eye line, printed or grooved where it is seen.
-
Layer 3
Acoustic carpet and rugs
A tile carpet with a dense polyester face on a felt backing. In Cuba, classrooms are hard and naturally ventilated with high ceilings and open circulation.
Over a resilient underlay. Where impact noise to the floor below is the actual complaint, the underlay does that work, not the carpet.
For a Cuba practice, the useful thing is a detail you can put in a drawing set, not a brochure. See how we support architects.
03 / Local conditions
The Cuba conditions that change the answer
- 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.
- Assembly and performance rooms
Theatres, church buildings and cultural centres are masonry volumes with very long decay.
- School and campus buildings
Classrooms are hard and naturally ventilated with high ceilings and open circulation.
04 / Room by room
What each space in a Cuba project needs
-
Classroom RT
A number, set against room volume, achieved mostly at the ceiling. Import formalities take real time here. We prepare the documentation package before shipping rather than after, and we quote the full window.
- Wood wool acoustic panels, 1200 x 600 mm
- Ceiling baffles and clouds, 9 to 24 mm
- Acoustic panels, Cut pattern in PET felt, adds visual rhythm without changing the absorber
-
Corridor spill
Long hard circulation feeds every room off it. Treating the corridor helps every classroom at once. Tall rooms with hard plaster and timber floors, where the structure stays and everything has to be done internally and shallow.
- Wood wool acoustic panels, 20 mm
- Ceiling baffles and clouds, Made to the drawing, standard and custom
- Acoustic panels, ASTM C423
-
Halls and gyms
Dual use rooms carrying speech, music and sport, where durability decides the product. PET felt does not absorb moisture, rot or feed mould, which matters on a Caribbean coast where mineral products fail quickly.
- 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
- Acoustic panels, 9 to 24 mm, 1220 x 2440 mm standard, up to 2440 x 4270 mm, 1200 to 3600 GSM
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
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.
If a consultant has set the target, we will quote against their figures rather than ours, and stay out of the scope they own. More on working with acoustic consultants.
06 / Straight talk
Where this kind of project usually fails
-
Panels at child height where they get damaged
This is the one that comes back as a second fit-out rather than a snag.
-
Treating one classroom and leaving the corridor
Small on the drawing, expensive on site, and almost always found after handover.
-
Choosing a product that cannot take a football
Noise with a source is fixed at the source. Treating the receiving room is the expensive way to get a small result.
-
Treating it as a generic Cuba job
Import formalities take real time here. We prepare the documentation package before shipping rather than after, and we quote the full window.
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 school and classroom acoustics different in Cuba?
Classrooms are hard and naturally ventilated with high ceilings and open circulation. 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?
Classroom RT. A number, set against room volume, achieved mostly at the ceiling. Corridor spill. Long hard circulation feeds every room off it. Treating the corridor helps every classroom at once.
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?
Panels at child height where they get damaged. Treating one classroom and leaving the corridor.
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
Drawings in, BOQ and a delivered date out
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.
