Cinema and multiplex soundproofing in Nagpur
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. Auditoriums, banquet halls and places of worship are large hard volumes in concrete and stone where speech falls apart long before anyone calls the room echoey.
- 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.

01 / What it is
The material, and what it actually does on a Nagpur job
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.
Auditoriums, banquet halls and places of worship are large hard volumes in concrete and stone where speech falls apart long before anyone calls the room echoey.
Work reaching us from Nagpur is mostly warehouses and processing units, colleges, hospitals, offices, auditoriums, hotels.
- Warehouse volumes Very large steel and concrete sheds where alarms and instructions have to be understood. Targeted absorption fixes intelligibility without touching the machines.
- Processing machinery Continuous plant noise close to occupied areas. Enclosure at the source is the reliable answer.
- Institutional buildings Colleges and hospitals in concrete and tile, where lecture rooms defeat the speaker and consult rooms offer no privacy.
- 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 Nagpur.
02 / The build-up
The build-up, layer by layer
-
Layer 1
SoundBlanket mass loaded vinyl
A limp, high density sheet that adds mass to a partition, floor or duct without adding depth. In Nagpur, split units, VRF outdoor banks and diesel generator sets sit close to occupied areas, often on the same terrace as a bedroom. Generator enclosure and condenser screening are the recurring jobs.
Floor, floating. Membrane under a resilient layer and a floating deck, so impact energy is broken before it reaches the slab.
-
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 Nagpur, auditoriums, banquet halls and places of worship are large hard volumes in concrete and stone where speech falls apart long before anyone calls the room echoey.
Resilient bar. Where a full independent leaf will not fit. Effective, and very easy to short circuit with one wrong screw.
-
Layer 3
PET felt acoustic panels
A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. In Nagpur, schools range from compact municipal buildings to large private campuses, all hard surfaced, with assembly halls doing duty as performance spaces.
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.
Architects working in Nagpur 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
What we see driving Nagpur briefs
- Warehouse volumes
Very large steel and concrete sheds where alarms and instructions have to be understood. Targeted absorption fixes intelligibility without touching the machines.
- Processing machinery
Continuous plant noise close to occupied areas. Enclosure at the source is the reliable answer.
- Institutional buildings
Colleges and hospitals in concrete and tile, where lecture rooms defeat the speaker and consult rooms offer no privacy.
- Dry heat
PET felt does not sag, shed fibre or degrade at high temperature, which matters in roof voids and rooms that get genuinely hot.
- Assembly and performance rooms
Auditoriums, banquet halls and places of worship are large hard volumes in concrete and stone where speech falls apart long before anyone calls the room echoey.

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
What the Nagpur climate rules in and rules out
Nagpur 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
What we watch go wrong on jobs like this
-
A shared service void running across the wall line
The ceiling is almost always the largest untreated surface, so leaving it out means paying for panels that cannot reach the target.
-
Treating the auditorium to fix bleed from the next screen
Small on the drawing, expensive on site, and almost always found after handover.
-
Doors and lobbies specified late and undersized
Soundproofing fails at the gaps, not the materials. One unsealed service penetration can undo a correctly built wall.
-
Treating it as a generic Nagpur job
Very large steel and concrete sheds where alarms and instructions have to be understood. Targeted absorption fixes intelligibility without touching the machines.
05 / Getting it there
Supply into Nagpur, start to site
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | two to three days |
| Dispatch | 2 to 4 working days |
| To site | two to three days |
| Support | Drawings, build-ups, BOQ and material that arrives complete |
Standard items dispatch in 2 to 4 working days from our plant at Palwal. Grooved panels and custom colours take longer, and we say so before you order, not after.
By road from Palwal, roughly eleven hundred kilometres, normally two to three days on a dedicated truck.
Questions from Nagpur projects
What makes cinema and multiplex soundproofing different in Nagpur?
Auditoriums, banquet halls and places of worship are large hard volumes in concrete and stone where speech falls apart long before anyone calls the room echoey. Very large steel and concrete sheds where alarms and instructions have to be understood. Targeted absorption fixes intelligibility without touching the machines.
Where should the budget go first on a Nagpur 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 Nagpur?
No. We manufacture in India and supply into Nagpur. 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 Nagpur site?
made at: Our own plant, Palwal, Haryana, reaches site in: two to three days, dispatch: 2 to 4 working days. Standard items dispatch in 2 to 4 working days from our plant at Palwal. 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.
