School and classroom acoustics in Bangkok
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. Classrooms are hard and naturally ventilated, open to traffic and corridor noise, with large class sizes pushing levels up.
- 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.

01 / The material
What this material is and where it earns its place in Bangkok
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.
Classrooms are hard and naturally ventilated, open to traffic and corridor noise, with large class sizes pushing levels up.
Work reaching us from Bangkok is mostly condo towers, hotels and lounges, offices, restaurants, clinics, studios.
- Elevated rail and traffic Trains and traffic close to facades put noise in through glazing, not through the wall. Fix the window path first.
- Concrete towers, live interiors The structure blocks a lot already. The problem is tile, glass and stone inside making the room ring, and that is a treatment job.
- Impact through slabs Hard flooring over concrete passes footfall straight down. A resilient underlay before the finish is the fix.
- 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 Bangkok.
02 / The build-up
The build-up, layer by layer
-
Layer 1
PET felt acoustic panels
A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. In Bangkok, split units and VRF with condensers on balconies and in light wells, running at full load most of the year.
On a 25 to 50 mm air gap. The same panel on battens. The air gap moves absorption down in frequency at no extra material cost, and is the cheapest improvement available.
-
Layer 2
Ceiling baffles and clouds
PET felt suspended from the soffit, vertically as baffles or horizontally as clouds. In Bangkok, temples, function halls and hotel ballrooms are tall hard volumes carrying amplified speech and music.
Vertical baffles. Hung on edge in rows. Both faces absorb, so coverage figures based on plan area understate them.
-
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 Bangkok, classrooms are hard and naturally ventilated, open to traffic and corridor noise, with large class sizes pushing levels up.
Ceiling first. In most rooms the ceiling is the largest untreated surface and the cheapest square metre of result.
Architects working in Bangkok usually need the build-up before the product. We will draw the section and mark what does the work. See how we support architects.

What decides the build-up in Bangkok
- Elevated rail and traffic
Trains and traffic close to facades put noise in through glazing, not through the wall. Fix the window path first.
- Concrete towers, live interiors
The structure blocks a lot already. The problem is tile, glass and stone inside making the room ring, and that is a treatment job.
- Impact through slabs
Hard flooring over concrete passes footfall straight down. A resilient underlay before the finish is the fix.
- Heat and humidity all year
Our PET felt does not hold moisture or feed mould, which matters where mineral products sag in a tropical climate.
- Assembly and performance rooms
Temples, function halls and hotel ballrooms are tall hard volumes carrying amplified speech and music.
- School and campus buildings
Classrooms are hard and naturally ventilated, open to traffic and corridor noise, with large class sizes pushing levels up.
04 / Room by room
Where the money goes on a Bangkok project
-
Classroom RT
A number, set against room volume, achieved mostly at the ceiling. Trains and traffic close to facades put noise in through glazing, not through the wall. Fix the window path first.
- PET felt acoustic panels, 100% PET non-woven, no added binder
- Ceiling baffles and clouds, 9 to 24 mm
- 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 blocks a lot already. The problem is tile, glass and stone inside making the room ring, and that is a treatment job.
- PET felt acoustic panels, 9, 12, 18 and 24 mm standard, tolerance plus or minus 5 percent
- Ceiling baffles and clouds, Made to the drawing, standard and custom
- Acoustic carpet and rugs, Felt
-
Halls and gyms
Dual use rooms carrying speech, music and sport, where durability decides the product. Hard flooring over concrete passes footfall straight down. A resilient underlay before the finish is the fix.
- PET felt acoustic panels, 4 to 24 mm
- Ceiling baffles and clouds, Both faces work, which is why suspended area outperforms the same area laid flat
- Acoustic carpet and rugs, 64 sq ft per pack
For a Bangkok interior where the finish leads, we will say plainly what each option costs you acoustically. See how we work with interior designers.
04 / Climate
The Bangkok climate decides the material list
Bangkok 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.
06 / Straight talk
The six errors that cost the most
-
Panels at child height where they get damaged
This is the one that comes back as a second fit-out rather than a snag.
-
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 Bangkok job
Trains and traffic close to facades put noise in through glazing, not through the wall. Fix the window path first.
05 / Supply
What the route into Bangkok actually looks like
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Laem Chabang, then a short road run into Bangkok |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Laem Chabang |
| 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 Laem Chabang, then a short road run into Bangkok. Air freight for samples and urgent quantities.
Questions from Bangkok projects
What makes school and classroom acoustics different in Bangkok?
Classrooms are hard and naturally ventilated, open to traffic and corridor noise, with large class sizes pushing levels up. The structure blocks a lot already. The problem is tile, glass and stone inside making the room ring, and that is a treatment job.
Where should the budget go first on a Bangkok 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 Bangkok?
No. We manufacture in India and supply into Bangkok. 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 Bangkok site?
ships from: Palwal, Haryana, India, arrives at: Laem Chabang, then a short road run into Bangkok, 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
We quote from drawings, not from a square foot rate. Send a plan and the section through the critical wall or ceiling and you will get something you can actually build from.
