HVAC, plant and machine noise control in Bhutan
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. Electric heating and split units, with plant close to occupied rooms in compact buildings.
- 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 product
What this material is and where it earns its place in Bhutan
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.
Electric heating and split units, with plant close to occupied rooms in compact buildings.
Work reaching us from Bhutan is mostly hotels and resorts, institutional buildings, assembly halls, schools, clinics, offices.
- No port, no container handling Entirely by road from our plant. Lead times are short and a small consignment is genuinely economic.
- Traditional construction Timber framing, rammed earth and masonry in buildings that must keep their character. Work has to be internal and respectful of the fabric.
- Seismic and mountainous Structures are built to move and the final road leg is steep and rough. We brace and wrap for both.
- 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 Bhutan.
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 Bhutan, electric heating and split units, with plant close to occupied rooms in compact buildings.
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 Bhutan, dzongs, monastery halls and civic rooms are tall hard volumes with long reverberation.
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 Bhutan, school buildings are hard surfaced with high ceilings, and halls carry assembly and performance.
Direct fix. Mechanically fixed to the soffit or wall. Durable and simple.
We would rather argue about the build-up at design stage than on site. See how we support architects.

What the buildings in Bhutan do to the specification
- No port, no container handling
Entirely by road from our plant. Lead times are short and a small consignment is genuinely economic.
- Traditional construction
Timber framing, rammed earth and masonry in buildings that must keep their character. Work has to be internal and respectful of the fabric.
- Seismic and mountainous
Structures are built to move and the final road leg is steep and rough. We brace and wrap for both.
- Hospitality at altitude
Hotels and lodges where guest room isolation matters more than anything happening inside the room itself.
- Plant and HVAC
Electric heating and split units, with plant close to occupied rooms in compact buildings.
04 / Room by room
Space by space, for Bhutan briefs
-
At source
Enclosure, barrier or anti vibration mounts at the machine. Entirely by road from our plant. Lead times are short and a small consignment is genuinely economic.
- 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
- 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. Timber framing, rammed earth and masonry in buildings that must keep their character. Work has to be internal and respectful of the fabric.
- 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
- 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. Structures are built to move and the final road leg is steep and rough. We brace and wrap for both.
- Soundproofing materials, Mass, then decoupling, then cavity absorption, then sealing
- Wood wool acoustic panels, 0.30
- 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
Durability in Bhutan, before acoustics is discussed
Bhutan 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 Bhutan job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.
06 / Before you buy
Six mistakes that turn into a second fit-out
-
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
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
This is the one that comes back as a second fit-out rather than a snag.
-
Treating it as a generic Bhutan job
Entirely by road from our plant. Lead times are short and a small consignment is genuinely economic.
05 / Route to site
Getting it to Bhutan, with real dates
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Overland through Phuentsholing, then road to site |
| Dispatch | 4 to 7 working days |
| Freight | Road via the India border |
| Support | Drawings, build-ups, BOQ and material that arrives complete |
Standard items dispatch in 4 to 7 working days. Grooved panels and custom colours take longer, and we say so before you order, not after.
Overland by road through the India border, then on to site. No sea leg and no port handling.
Questions from Bhutan projects
What makes HVAC, plant and machine noise control different in Bhutan?
Electric heating and split units, with plant close to occupied rooms in compact buildings. Entirely by road from our plant. Lead times are short and a small consignment is genuinely economic.
Where should the budget go first on a Bhutan 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 Bhutan?
No. We manufacture in India and supply into Bhutan. 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 Bhutan site?
ships from: Palwal, Haryana, India, arrives at: Overland through Phuentsholing, then road to site, dispatch: 4 to 7 working days. Standard items dispatch in 4 to 7 working days. Grooved panels and custom colours take longer, and we say so before you order, not after.
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.

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.
