HVAC, plant and machine noise control in Colombia
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 with condensers on facades and in light wells, running through a mild year round climate.
- 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 / What it is
The product, described honestly, for a Colombia 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 units with condensers on facades and in light wells, running through a mild year round climate.
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.
- 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 Colombia.
02 / The build-up
What goes where, from the structure in
-
Layer 1
SoundBlanket mass loaded vinyl
A limp, high density sheet that adds mass to a partition, floor or duct without adding depth. In Colombia, split units with condensers on facades and in light wells, running through a mild year round climate.
Duct and plant wrap. Membrane wrapped over the duct with a decoupling layer beneath, sealed at every lap.
-
Layer 2
Wood wool acoustic panels
Wood fibre bound into a rigid board with an open texture. In Colombia, church buildings, event halls and auditoria are hard volumes carrying amplified music at high level.
Direct fix. Mechanically fixed to the soffit or wall. Durable and simple.
-
Layer 3
Ceiling baffles and clouds
PET felt suspended from the soffit, vertically as baffles or horizontally as clouds. In Colombia, classrooms are concrete and tile with high ceilings, and covered play areas amplify break time noise.
Horizontal clouds. Flat rafts over the occupied zone, which also reflect early speech energy back down where it helps.
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 / On the ground
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.
- Plant and HVAC
Split units with condensers on facades and in light wells, running through a mild year round climate.
04 / Room by room
Where the money goes on a Colombia project
-
At source
Enclosure, barrier or anti vibration mounts at the machine. 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.
- SoundBlanket mass loaded vinyl, 2100 kg per cubic metre
- Wood wool acoustic panels, 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. Walls carry mass. The recurring problem is hard, live interiors and services noise rather than speech through a wall.
- SoundBlanket mass loaded vinyl, STC 30, 5.25 kg per sq m
- 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
-
At the receiver
Only after the first two, and only for what is left. Hotel and restaurant fit-out is a steady share of enquiries, and those rooms are judged when they are completely full.
- SoundBlanket mass loaded vinyl, STC 34, 8.4 kg per sq m
- Wood wool acoustic panels, 0.30
- Ceiling baffles and clouds, ASTM C423
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 / Conditions
Durability in Colombia, before acoustics is discussed
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.
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.

What we watch go wrong on jobs like this
-
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
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
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 / Route to site
Supply into Colombia, start to site
| 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 HVAC, plant and machine noise control different in Colombia?
Split units with condensers on facades and in light wells, running through a mild year round climate. 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?
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 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?
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.
