Office acoustics and soundproofing in Bangladesh
Three separate problems get called one problem: speech carrying across an open floor, meeting rooms that leak, and hard rooms that ring. Each has a different answer and mixing them up is how budgets get wasted. Split units and diesel generator sets, with generators close to occupied rooms and running often.
- Open plan
- Distraction distance, not reverberation time. Ceiling absorption plus screens at the desk.
- Meeting rooms
- Privacy between rooms. That is partition and door work, not panels.
- Cabins and calls
- Short RT so a call sounds clean. A small amount of well placed absorber.

01 / What it is
The material, and what it actually does on a Bangladesh job
Three separate problems get called one problem: speech carrying across an open floor, meeting rooms that leak, and hard rooms that ring. Each has a different answer and mixing them up is how budgets get wasted.
Split units and diesel generator sets, with generators close to occupied rooms and running often.
Work reaching us from Bangladesh is mostly garment and manufacturing units, generator and plant rooms, offices, hospitals, schools, hotels.
- Reachable by road The land border makes this one of our shortest export routes. You can order what the job needs rather than over-ordering against a long sea transit.
- Garment units at scale Large production floors with continuous machine noise and rooms where instructions and alarms have to be understood. Enclosure first, absorption second.
- Generators run constantly Standby and continuous generation sits close to occupied space almost everywhere. That is mass and enclosure work, not panels.
- Open plan Distraction distance, not reverberation time. Ceiling absorption plus screens at the desk.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for office acoustics are on the main product page. This page covers what that means for a project in Bangladesh.

02 / The build-up
How the layers stack, from the structure inwards
-
Layer 1
Ceiling baffles and clouds
PET felt suspended from the soffit, vertically as baffles or horizontally as clouds. In Bangladesh, split units and diesel generator sets, with generators close to occupied rooms and running often.
Horizontal clouds. Flat rafts over the occupied zone, which also reflect early speech energy back down where it helps.
-
Layer 2
PET felt acoustic panels
A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. In Bangladesh, community halls, places of worship and conference rooms are hard volumes carrying amplified speech.
Direct to wall. Panel bonded or mechanically fixed flat to the substrate. Simplest, and the weakest at low frequency.
-
Layer 3
Acoustic carpet and rugs
A tile carpet with a dense polyester face on a felt backing. In Bangladesh, classrooms are concrete and tile with very large class sizes, and street noise enters through open windows all day.
Over a resilient underlay. Where impact noise to the floor below is the actual complaint, the underlay does that work, not the carpet.
For a Bangladesh practice, the useful thing is a detail you can put in a drawing set, not a brochure. See how we support architects.
03 / In this market
What decides the build-up in Bangladesh
- Reachable by road
The land border makes this one of our shortest export routes. You can order what the job needs rather than over-ordering against a long sea transit.
- Garment units at scale
Large production floors with continuous machine noise and rooms where instructions and alarms have to be understood. Enclosure first, absorption second.
- Generators run constantly
Standby and continuous generation sits close to occupied space almost everywhere. That is mass and enclosure work, not panels.
- Dense, humid, monsoon climate
PET felt does not hold moisture or feed mould, which decides whether a ceiling survives more than a couple of seasons.
- Plant and HVAC
Split units and diesel generator sets, with generators close to occupied rooms and running often.
04 / Room by room
What each space in a Bangladesh project needs
-
Open plan
Distraction distance, not reverberation time. Ceiling absorption plus screens at the desk. The land border makes this one of our shortest export routes. You can order what the job needs rather than over-ordering against a long sea transit.
- Ceiling baffles and clouds, 100% PET non-woven, the panel family
- Acoustic carpet and rugs, 4 mm
- Acoustic panels, Cut pattern in PET felt, adds visual rhythm without changing the absorber
-
Meeting rooms
Privacy between rooms. That is partition and door work, not panels. Large production floors with continuous machine noise and rooms where instructions and alarms have to be understood. Enclosure first, absorption second.
- Ceiling baffles and clouds, 9 to 24 mm
- Acoustic carpet and rugs, High density polyester
- Acoustic panels, ASTM C423
-
Cabins and calls
Short RT so a call sounds clean. A small amount of well placed absorber. Standby and continuous generation sits close to occupied space almost everywhere. That is mass and enclosure work, not panels.
- Ceiling baffles and clouds, Made to the drawing, standard and custom
- Acoustic carpet and rugs, Felt
- Acoustic panels, 9 to 24 mm, 1220 x 2440 mm standard, up to 2440 x 4270 mm, 1200 to 3600 GSM
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 Bangladesh changes the material, not the target
Bangladesh 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.

Where this kind of project usually fails
-
Lining every wall while leaving the ceiling bare
Square metre for square metre the ceiling is the cheapest result in the room. Skipping it and buying wall panels instead is the most common way to overspend.
-
Treating a privacy problem with absorption
If the complaint is being overheard, no amount of absorption inside the room will fix it. That is a partition job and we will say so.
-
Glass cabins specified without a door and head detail
A 6 mm undercut under a door leaves a hole the size of a brick. The wall around it is then decorative.
-
Treating it as a generic Bangladesh job
The land border makes this one of our shortest export routes. You can order what the job needs rather than over-ordering against a long sea transit.
05 / Route to site
How material reaches a Bangladesh site
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Chattogram by sea, or overland through the land border |
| Dispatch | 4 to 7 working days |
| Freight | Sea or land 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.
Sea freight into Chattogram, or overland through the land border where that suits the programme better. Air freight for samples and urgent quantities.
Questions from Bangladesh projects
What makes office acoustics and soundproofing different in Bangladesh?
Split units and diesel generator sets, with generators close to occupied rooms and running often. The land border makes this one of our shortest export routes. You can order what the job needs rather than over-ordering against a long sea transit.
Where should the budget go first on a Bangladesh project?
Open plan. Distraction distance, not reverberation time. Ceiling absorption plus screens at the desk. Meeting rooms. Privacy between rooms. That is partition and door work, not panels.
Do you have an office or installation team in Bangladesh?
No. We manufacture in India and supply into Bangladesh. 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 Bangladesh site?
ships from: Palwal, Haryana, India, arrives at: Chattogram by sea, or overland through the land border, 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?
Lining every wall while leaving the ceiling bare. Treating a privacy problem with absorption.
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.
