Cinema and multiplex soundproofing in Bangladesh
Screens stacked beside and above each other, each running full range at high level. Bleed between auditoria is the failure everyone hears, and it is decided by the shell, not the finishes. Community halls, places of worship and conference rooms are hard volumes carrying amplified speech.
- Screen to screen
- Independent construction between auditoria, with services broken at the line.
- In room response
- Heavy absorption on side and rear walls so the mix is heard as intended.
- Plant and projection
- Equipment noise into the auditorium, treated at source.

What this is, and what it changes in a Bangladesh room
Screens stacked beside and above each other, each running full range at high level. Bleed between auditoria is the failure everyone hears, and it is decided by the shell, not the finishes.
Community halls, places of worship and conference rooms are hard volumes carrying amplified speech.
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.
- Screen to screen Independent construction between auditoria, with services broken at the line.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for cinema soundproofing are on the main product page. This page covers what that means for a project in Bangladesh.
02 / The build-up
The stack, in the order it is installed
-
Layer 1
SoundBlanket mass loaded vinyl
A limp, high density sheet that adds mass to a partition, floor or duct without adding depth. In Bangladesh, split units and diesel generator sets, with generators close to occupied rooms and running often.
Wall, decoupled. Independent stud, membrane between the boards, cavity absorption, two boards. The membrane is one part of a system, never the whole answer.
-
Layer 2
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 Bangladesh, community halls, places of worship and conference rooms are hard volumes carrying amplified speech.
Mixed finish. Plain felt where it is out of eye line, printed or grooved where it is seen.
-
Layer 3
PET felt acoustic panels
A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. In Bangladesh, classrooms are concrete and tile with very large class sizes, and street noise enters through open windows all day.
Over a porous backing. Panel over mineral or PET backing where the room needs genuine low mid control.
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 / Local conditions
What we see driving Bangladesh briefs
- 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.
- Assembly and performance rooms
Community halls, places of worship and conference rooms are hard volumes carrying amplified speech.

Screen to screen
Independent construction between auditoria, with services broken at the line. 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.
- SoundBlanket mass loaded vinyl, 2100 kg per cubic metre
- Acoustic carpet and rugs, 4 mm
- PET felt acoustic panels, 4 to 24 mm
-
In room response
Heavy absorption on side and rear walls so the mix is heard as intended. Large production floors with continuous machine noise and rooms where instructions and alarms have to be understood. Enclosure first, absorption second.
- SoundBlanket mass loaded vinyl, STC 30, 5.25 kg per sq m
- Acoustic carpet and rugs, High density polyester
- PET felt acoustic panels, 1220 x 2440 mm standard, 4 x 8 ft
-
Plant and projection
Equipment noise into the auditorium, treated at source. Standby and continuous generation sits close to occupied space almost everywhere. That is mass and enclosure work, not panels.
- SoundBlanket mass loaded vinyl, STC 34, 8.4 kg per sq m
- Acoustic carpet and rugs, Felt
- PET felt acoustic panels, 2440 x 4270 mm, 2.44 x 4.27 m, 8 x 14 ft
Designers get colour, pattern and CNC options with the absorption figure attached to each. See how we work with interior designers.
04 / Climate and 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.
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 / Worth knowing
The six errors that cost the most
-
A shared service void running across the wall line
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 the auditorium to fix bleed from the next screen
It sounds like a small detail until the room is finished and the complaint arrives.
-
Doors and lobbies specified late and undersized
A gap undoes the partition it sits in. Sealing is the cheapest line on the quote and the first one to get cut.
-
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 / Logistics
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 cinema and multiplex soundproofing different in Bangladesh?
Community halls, places of worship and conference rooms are hard volumes carrying amplified speech. 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?
Screen to screen. Independent construction between auditoria, with services broken at the line. In room response. Heavy absorption on side and rear walls so the mix is heard as intended.
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?
A shared service void running across the wall line. Treating the auditorium to fix bleed from the next screen.
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.
