HVAC, plant and machine noise control in Peru
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 rooftops, running through a mild coastal 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.

01 / The material
What you are buying, and what it fixes in Peru
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 rooftops, running through a mild coastal climate.
Work reaching us from Peru is mostly offices, apartments, mining and industrial facilities, hotels, hospitals, schools.
- Callao is next to the market The port sits beside Lima, so most commercial deliveries have almost no inland leg. Mining sites inland are a different calculation and we quote them separately.
- Mining plant and control rooms Continuous machinery and rooms where operators listen for alarms. Enclosure and a low background, not decorative absorption.
- Dry coastal climate Lima is dry and mild. Material stability is straightforward, and PET felt does not degrade or shed in these conditions.
- 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 Peru.
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 Peru, split units with condensers on facades and rooftops, running through a mild coastal climate.
With a porous backing. Board over mineral backing where the room needs more than the board alone gives.
-
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 Peru, church buildings and event halls are hard volumes carrying amplified speech and music.
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 Peru, classrooms are concrete and tile with large class sizes and open courtyards that carry sound.
Vertical baffles. Hung on edge in rows. Both faces absorb, so coverage figures based on plan area understate them.
For a Peru practice, the useful thing is a detail you can put in a drawing set, not a brochure. See how we support architects.
03 / On the ground
The Peru conditions that change the answer
- Callao is next to the market
The port sits beside Lima, so most commercial deliveries have almost no inland leg. Mining sites inland are a different calculation and we quote them separately.
- Mining plant and control rooms
Continuous machinery and rooms where operators listen for alarms. Enclosure and a low background, not decorative absorption.
- Dry coastal climate
Lima is dry and mild. Material stability is straightforward, and PET felt does not degrade or shed in these conditions.
- Concrete construction
Walls carry mass, so hard live interiors and services noise are the usual complaints rather than transmission between rooms.
- Plant and HVAC
Split units with condensers on facades and rooftops, running through a mild coastal climate.

Room by room, on a typical Peru job

At source
Enclosure, barrier or anti vibration mounts at the machine. The port sits beside Lima, so most commercial deliveries have almost no inland leg. Mining sites inland are a different calculation and we quote them separately.
- 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
- Wood wool acoustic panels, 20 mm
- 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. Continuous machinery and rooms where operators listen for alarms. Enclosure and a low background, not decorative absorption.
- Soundproofing materials, 1800 x 900 x 20 mm, 100 kg per cubic metre, NRC 0.85
- Wood wool acoustic panels, 400 kg per cubic metre
- Acoustic foam and BassBloc, 100 to 500 Hz
-
At the receiver
Only after the first two, and only for what is left. Lima is dry and mild. Material stability is straightforward, and PET felt does not degrade or shed in these conditions.
- Soundproofing materials, Mass, then decoupling, then cavity absorption, then sealing
- Wood wool acoustic panels, 0.30
- 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 / Durability
Why the climate in Peru changes the material, not the target
Peru 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.
Where a consultant is already engaged on a Peru project, we supply to their specification and send the test reports rather than describing them. More on working with acoustic consultants.
06 / Worth knowing
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
Enclose the machine, break the vibration path, then deal with what is left. Doing it in the other order costs more and achieves less.
-
Ignoring structure borne vibration through the mounts
Small on the drawing, expensive on site, and almost always found after handover.
-
Treating it as a generic Peru job
The port sits beside Lima, so most commercial deliveries have almost no inland leg. Mining sites inland are a different calculation and we quote them separately.
05 / Logistics
Getting it to Peru, with real dates
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Callao, next to Lima, then road to site |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Callao |
| 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 Callao, then a short road run for Lima work or a longer inland leg for mining sites. Air freight for samples.
Questions from Peru projects
What makes HVAC, plant and machine noise control different in Peru?
Split units with condensers on facades and rooftops, running through a mild coastal climate. The port sits beside Lima, so most commercial deliveries have almost no inland leg. Mining sites inland are a different calculation and we quote them separately.
Where should the budget go first on a Peru 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 Peru?
No. We manufacture in India and supply into Peru. 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 Peru site?
ships from: Palwal, Haryana, India, arrives at: Callao, next to Lima, 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
Drawings in, BOQ and a delivered date out
A plan and a section is enough. We will come back with a build-up, a BOQ and a delivered date, and we will say so if what you are asking for will not work.
