Cinema and multiplex soundproofing in Dehradun
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. Hotel banquet rooms, auditoria and temple halls are hard volumes carrying amplified speech and music.
- 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 product, described honestly, for a Dehradun brief
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.
Hotel banquet rooms, auditoria and temple halls are hard volumes carrying amplified speech and music.
Work reaching us from Dehradun is mostly boarding schools and colleges, assembly halls, dormitories, hotels, hospitals, offices.
- Classrooms defeat the teacher Hard floors, high ceilings and hard plaster mean a teacher raises their voice all day. Absorption on the ceiling recovers most of it.
- Halls used for everything Assembly, examinations, performances and sport in one room. The design has to work for speech first and music second.
- Dormitories Children sleeping next to corridors and each other. Partition and door detailing does more than anything applied inside the room.
- 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 Dehradun.
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 Dehradun, hotel plant, boilers and generator sets close to guest rooms in compact hillside buildings.
Duct and plant wrap. Membrane wrapped over the duct with a decoupling layer beneath, sealed at every lap.
-
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 Dehradun, hotel banquet rooms, auditoria and temple halls are hard volumes carrying amplified speech and music.
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 Dehradun, classrooms are concrete and tile with bare walls and high ceilings, and class sizes push levels up. Corridors act as reverberation chambers that feed every room off them.
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.
If you are specifying for a Dehradun project, we can give you a section, a BOQ and the honest limits of each layer. See how we support architects.
03 / What drives the brief
The Dehradun conditions that change the answer
- Classrooms defeat the teacher
Hard floors, high ceilings and hard plaster mean a teacher raises their voice all day. Absorption on the ceiling recovers most of it.
- Halls used for everything
Assembly, examinations, performances and sport in one room. The design has to work for speech first and music second.
- Dormitories
Children sleeping next to corridors and each other. Partition and door detailing does more than anything applied inside the room.
- Next day from the plant
A short run, so freight stays low and samples arrive before the order.
- Assembly and performance rooms
Hotel banquet rooms, auditoria and temple halls are hard volumes carrying amplified speech and music.

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 / Conditions
Why the climate in Dehradun changes the material, not the target
Dehradun 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 Dehradun job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.
06 / Read this first
Six mistakes that turn into a second fit-out
-
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
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 Dehradun job
Hard floors, high ceilings and hard plaster mean a teacher raises their voice all day. Absorption on the ceiling recovers most of it.
05 / Logistics
What the route into Dehradun actually looks like
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | next day |
| Dispatch | 2 to 4 working days |
| To site | next day |
| 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 three hundred kilometres, normally next day on a dedicated truck.
Questions from Dehradun projects
What makes cinema and multiplex soundproofing different in Dehradun?
Hotel banquet rooms, auditoria and temple halls are hard volumes carrying amplified speech and music. Hard floors, high ceilings and hard plaster mean a teacher raises their voice all day. Absorption on the ceiling recovers most of it.
Where should the budget go first on a Dehradun 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 Dehradun?
No. We manufacture in India and supply into Dehradun. 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 Dehradun site?
made at: Our own plant, Palwal, Haryana, reaches site in: next day, 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.

Drawings in, BOQ and a delivered date out
Send what you have. We will give you a layer by layer build-up, a bill of quantities and a date material lands, and we will flag anything in the brief that will not achieve what you want.
