School and classroom acoustics in South Korea
Hard floors, bare walls and long corridors that amplify everything. Children with developing language, and anyone with a hearing difficulty, lose more from a live classroom than adults do, which is why intelligibility is the target rather than quiet. School and academy buildings are hard surfaced with long corridors and very intensive use.
- Classroom RT
- A number, set against room volume, achieved mostly at the ceiling.
- Corridor spill
- Long hard circulation feeds every room off it. Treating the corridor helps every classroom at once.
- Halls and gyms
- Dual use rooms carrying speech, music and sport, where durability decides the product.

The material, and what it actually does on a South Korea job
Hard floors, bare walls and long corridors that amplify everything. Children with developing language, and anyone with a hearing difficulty, lose more from a live classroom than adults do, which is why intelligibility is the target rather than quiet.
School and academy buildings are hard surfaced with long corridors and very intensive use.
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.
- Classroom RT A number, set against room volume, achieved mostly at the ceiling.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for school acoustics are on the main product page. This page covers what that means for a project in South Korea.
02 / The build-up
How the layers stack, from the structure inwards
-
Layer 1
PET felt acoustic panels
A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. In South Korea, central plant and split units, with risers and duct runs carrying noise between floors.
Over a porous backing. Panel over mineral or PET backing where the room needs genuine low mid control.
-
Layer 2
Wood wool acoustic panels
Wood fibre bound into a rigid board with an open texture. In South Korea, church buildings, halls and auditoria are large hard volumes carrying amplified speech and music.
On a cavity. Mounted on battens with an air gap, which is where the low mid performance comes from.
-
Layer 3
Acoustic panels
The full absorber range rather than one product: plain PET felt, printed felt, grooved panels and fabric finishes, chosen by how the room is used and how it has to look. In South Korea, school and academy buildings are hard surfaced with long corridors and very intensive use.
Mixed finish. Plain felt where it is out of eye line, printed or grooved where it is seen.
Architects working in South Korea usually need the build-up before the product. We will draw the section and mark what does the work. See how we support architects.
03 / On the ground
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.
- Assembly and performance rooms
Church buildings, halls and auditoria are large hard volumes carrying amplified speech and music.
- School and campus buildings
School and academy buildings are hard surfaced with long corridors and very intensive use.
04 / Room by room
Space by space, for South Korea briefs
-
Classroom RT
A number, set against room volume, achieved mostly at the ceiling. 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.
- Wood wool acoustic panels, 1200 x 600 mm
- Acoustic panels, 1800 x 900 mm, image printed into the felt rather than onto a facing
- Acoustic carpet and rugs, High density polyester
-
Corridor spill
Long hard circulation feeds every room off it. Treating the corridor helps every classroom at once. The structure carries mass, so airborne transfer is rarely the problem. Structure-borne and impact paths are.
- Wood wool acoustic panels, 20 mm
- Acoustic panels, Cut pattern in PET felt, adds visual rhythm without changing the absorber
- Acoustic carpet and rugs, Felt
-
Halls and gyms
Dual use rooms carrying speech, music and sport, where durability decides the product. Specifications here are written carefully and checked. Send us the target and we will say plainly what our material reaches.
- Wood wool acoustic panels, 400 kg per cubic metre
- Acoustic panels, ASTM C423
- Acoustic carpet and rugs, 64 sq ft per pack
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
Why the climate in South Korea changes the material, not the target
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.
On a South Korea 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
-
Panels at child height where they get damaged
Small on the drawing, expensive on site, and almost always found after handover.
-
Treating one classroom and leaving the corridor
Small on the drawing, expensive on site, and almost always found after handover.
-
Choosing a product that cannot take a football
Noise with a source is fixed at the source. Treating the receiving room is the expensive way to get a small result.

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 / Route to site
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 school and classroom acoustics different in South Korea?
School and academy buildings are hard surfaced with long corridors and very intensive use. 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?
Classroom RT. A number, set against room volume, achieved mostly at the ceiling. Corridor spill. Long hard circulation feeds every room off it. Treating the corridor helps every classroom at once.
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?
Panels at child height where they get damaged. Treating one classroom and leaving the corridor.
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.
