For projects in Colombia
Auditorium acoustics and soundproofing in Colombia
A large hard volume where speech falls apart long before anyone calls the room echoey. The target is intelligibility at the back row, which is a reverberation and early reflection problem, not a loudspeaker problem. Church buildings, event halls and auditoria are hard volumes carrying amplified music at high level.
- Reverberation time
- Set against use. Speech and music want different numbers, and a dual use hall needs a decision.
- Early reflections
- Shaped surfaces that send energy to the rear seats rather than absorbing everything.
- Rear wall
- The single worst surface in most halls, and the first one to treat.

01 / The product
What you are buying, and what it fixes in Colombia
A large hard volume where speech falls apart long before anyone calls the room echoey. The target is intelligibility at the back row, which is a reverberation and early reflection problem, not a loudspeaker problem.
Church buildings, event halls and auditoria are hard volumes carrying amplified music at high level.
Work reaching us from Colombia is mostly offices, apartments, hotels, restaurants, hospitals, schools, studios.
- The inland leg is significant The commercial centres are well inland and high up. We quote the port leg and the road leg separately so the programme runs on real dates.
- Concrete and brick construction Walls carry mass. The recurring problem is hard, live interiors and services noise rather than speech through a wall.
- Growing hospitality sector Hotel and restaurant fit-out is a steady share of enquiries, and those rooms are judged when they are completely full.
- Reverberation time Set against use. Speech and music want different numbers, and a dual use hall needs a decision.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for auditorium acoustics are on the main product page. This page covers what that means for a project in Colombia.
02 / The build-up
How the layers stack, from the structure inwards
-
Layer 1
Wood wool acoustic panels
Wood fibre bound into a rigid board with an open texture. In Colombia, split units with condensers on facades and in light wells, running through a mild year round climate.
Direct fix. Mechanically fixed to the soffit or wall. Durable and simple.
-
Layer 2
Wooden slat acoustic panels
Timber slats on an acoustic backing. In Colombia, church buildings, event halls and auditoria are hard volumes carrying amplified music at high level.
Feature wall only. Slats where they are seen, plain felt elsewhere, to hold the budget where it shows.
-
Layer 3
PET felt acoustic panels
A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. In Colombia, classrooms are concrete and tile with high ceilings, and covered play areas amplify break time noise.
On a 25 to 50 mm air gap. The same panel on battens. The air gap moves absorption down in frequency at no extra material cost, and is the cheapest improvement available.
If you are specifying for a Colombia 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 we see driving Colombia briefs
- The inland leg is significant
The commercial centres are well inland and high up. We quote the port leg and the road leg separately so the programme runs on real dates.
- Concrete and brick construction
Walls carry mass. The recurring problem is hard, live interiors and services noise rather than speech through a wall.
- Growing hospitality sector
Hotel and restaurant fit-out is a steady share of enquiries, and those rooms are judged when they are completely full.
- Two coasts to choose from
Cartagena on the Caribbean or Buenaventura on the Pacific, routed to whichever shortens the run to your site.
- Assembly and performance rooms
Church buildings, event halls and auditoria are hard volumes carrying amplified music at high level.
- School and campus buildings
Classrooms are concrete and tile with high ceilings, and covered play areas amplify break time noise.
04 / Room by room
What each space in a Colombia project needs
-
Reverberation time
Set against use. Speech and music want different numbers, and a dual use hall needs a decision. The commercial centres are well inland and high up. We quote the port leg and the road leg separately so the programme runs on real dates.
- Wood wool acoustic panels, 1200 x 600 mm
- Wooden slat acoustic panels, 13-3, 14-2, 28-4 and 59-5
- Ceiling baffles and clouds, Made to the drawing, standard and custom
-
Early reflections
Shaped surfaces that send energy to the rear seats rather than absorbing everything. Walls carry mass. The recurring problem is hard, live interiors and services noise rather than speech through a wall.
- Wood wool acoustic panels, 20 mm
- Wooden slat acoustic panels, 2440 x 192 mm and 2440 x 128 mm
- Ceiling baffles and clouds, Both faces work, which is why suspended area outperforms the same area laid flat
-
Rear wall
The single worst surface in most halls, and the first one to treat. Hotel and restaurant fit-out is a steady share of enquiries, and those rooms are judged when they are completely full.
- Wood wool acoustic panels, 400 kg per cubic metre
- Wooden slat acoustic panels, 14, 16 and 18 mm
- 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 / Climate and durability
The Colombia climate decides the material list
Colombia is warm and humid through most of the year, with a long wet season, and that narrows the material list before acoustics is discussed.
Humidity is the deciding factor. PET felt does not absorb moisture, shed fibre or feed mould, which is why it outlasts fabric-wrapped mineral wool in this climate. Wood wool and timber need a ventilated cavity behind them.
The failure we design against here is mould, sagging fabric finishes and swelling in timber.
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 / Straight talk
Where this kind of project usually fails
-
Absorbing the whole room and losing the back rows
Small on the drawing, expensive on site, and almost always found after handover.
-
Adding speakers to fix a reverberation problem
It sounds like a small detail until the room is finished and the complaint arrives.
-
Ignoring the rear wall because it is behind the audience
It sounds like a small detail until the room is finished and the complaint arrives.
-
Treating it as a generic Colombia job
The commercial centres are well inland and high up. We quote the port leg and the road leg separately so the programme runs on real dates.
05 / Supply
What the route into Colombia actually looks like
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Cartagena or Buenaventura, then road inland |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Cartagena |
| 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 Cartagena or Buenaventura, then road inland. Air freight for samples and urgent quantities.
Questions from Colombia projects
What makes auditorium acoustics and soundproofing different in Colombia?
Church buildings, event halls and auditoria are hard volumes carrying amplified music at high level. The commercial centres are well inland and high up. We quote the port leg and the road leg separately so the programme runs on real dates.
Where should the budget go first on a Colombia project?
Reverberation time. Set against use. Speech and music want different numbers, and a dual use hall needs a decision. Early reflections. Shaped surfaces that send energy to the rear seats rather than absorbing everything.
Do you have an office or installation team in Colombia?
No. We manufacture in India and supply into Colombia. 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 Colombia site?
ships from: Palwal, Haryana, India, arrives at: Cartagena or Buenaventura, then road inland, 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?
Absorbing the whole room and losing the back rows. Adding speakers to fix a reverberation problem.
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.
