HVAC, plant and machine noise control in South Korea
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. Central plant and split units, with risers and duct runs carrying noise between floors.
- 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.
- Quote
- From a plan and a section, within 48 hours
01 / What it is
The product, described honestly, for a South Korea 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.
Central plant and split units, with risers and duct runs carrying noise between floors.
Work reaching us from South Korea is mostly apartment towers, manufacturing plants, offices, hotels, schools, studios.
- Noise between floors is the issue Impact from the flat above is the defining residential complaint in this market. It is a floor build-up question, and a ceiling treatment below will not answer it.
- Concrete towers throughout The structure carries mass, so airborne transfer is rarely the problem. Structure-borne and impact paths are.
- Precise expectations Specifications here are written carefully and checked. Send us the target and we will say plainly what our material reaches.
- 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 South Korea.
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 South Korea, central plant and split units, with risers and duct runs carrying noise between floors.
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 South Korea, church buildings, halls and auditoria are large hard volumes carrying amplified speech and music.
Floating floor. Resilient layer and deck, to break impact energy before it reaches the structure.
-
Layer 3
Ceiling baffles and clouds
PET felt suspended from the soffit, vertically as baffles or horizontally as clouds. In South Korea, school and academy buildings are hard surfaced with long corridors and very intensive use.
Vertical baffles. Hung on edge in rows. Both faces absorb, so coverage figures based on plan area understate them.
We would rather argue about the build-up at design stage than on site. See how we support architects.
03 / What drives the brief
The South Korea conditions that change the answer
- Noise between floors is the issue
Impact from the flat above is the defining residential complaint in this market. It is a floor build-up question, and a ceiling treatment below will not answer it.
- Concrete towers throughout
The structure carries mass, so airborne transfer is rarely the problem. Structure-borne and impact paths are.
- Precise expectations
Specifications here are written carefully and checked. Send us the target and we will say plainly what our material reaches.
- Two strong ports
Busan and Incheon are both well served from India, so we route to whichever suits the site.
- Plant and HVAC
Central plant and split units, with risers and duct runs carrying noise between floors.
04 / Room by room
Space by space, for South Korea briefs
-
At source
Enclosure, barrier or anti vibration mounts at the machine. Impact from the flat above is the defining residential complaint in this market. It is a floor build-up question, and a ceiling treatment below will not answer it.
- 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
- Acoustic foam and BassBloc, 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. The structure carries mass, so airborne transfer is rarely the problem. Structure-borne and impact paths are.
- Soundproofing materials, 1800 x 900 x 20 mm, 100 kg per cubic metre, NRC 0.85
- Acoustic foam and BassBloc, 100 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. Specifications here are written carefully and checked. Send us the target and we will say plainly what our material reaches.
- Soundproofing materials, Mass, then decoupling, then cavity absorption, then sealing
- Acoustic foam and BassBloc, 100 to 500 Hz
- Ceiling baffles and clouds, ASTM C423
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
The South Korea climate decides the material list
South Korea 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.
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
The six errors that cost the most
-
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
This is the one that comes back as a second fit-out rather than a snag.
-
Treating it as a generic South Korea job
Impact from the flat above is the defining residential complaint in this market. It is a floor build-up question, and a ceiling treatment below will not answer it.
05 / Supply
Getting it to South Korea, with real dates
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Busan or Incheon, then road to site |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Busan |
| 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.
Sea freight into Busan or Incheon, then road to site. Air freight for samples and urgent quantities.
Questions from South Korea projects
What makes HVAC, plant and machine noise control different in South Korea?
Central plant and split units, with risers and duct runs carrying noise between floors. Impact from the flat above is the defining residential complaint in this market. It is a floor build-up question, and a ceiling treatment below will not answer it.
Where should the budget go first on a South Korea 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 South Korea?
No. We manufacture in India and supply into South Korea. 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 South Korea site?
ships from: Palwal, Haryana, India, arrives at: Busan or Incheon, 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.
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.
