Cinema and multiplex soundproofing in New Zealand
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. School halls, marae and community centres carry speech and performance in the same hard room.
- 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 / The material
What this is, and what it changes in a New Zealand 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.
School halls, marae and community centres carry speech and performance in the same hard room.
Work reaching us from New Zealand is mostly timber frame housing, apartments, offices, schools, clinics, studios.
- Timber frame, very little mass Light construction passes low frequency easily. Added mass and a decoupled layer do the work, and absorption alone will not.
- Designed to move Seismic detailing means junctions and joints that have to stay flexible. An acoustic build-up has to respect that rather than bridge it rigidly.
- A long sea leg This is one of the longest routes we run. Ordering to a real schedule matters more here than anywhere else, so we quote the full window.
- 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 New Zealand.
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 New Zealand, heat pumps and ducted systems, with outdoor units close to boundaries in dense suburbs.
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 New Zealand, school halls, marae and community centres carry speech and performance in the same hard room.
Wall array. Panels placed at first reflection points rather than spread evenly. Fewer panels, better result.
-
Layer 3
Acoustic carpet and rugs
A tile carpet with a dense polyester face on a felt backing. In New Zealand, classroom acoustics are taken seriously and open plan learning spaces are common, which makes speech intelligibility the design target.
Zoned. Carpet in the circulation and meeting zones, hard floor elsewhere, so the treatment sits where the noise is made.
For a New Zealand 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 the buildings in New Zealand do to the specification
- Timber frame, very little mass
Light construction passes low frequency easily. Added mass and a decoupled layer do the work, and absorption alone will not.
- Designed to move
Seismic detailing means junctions and joints that have to stay flexible. An acoustic build-up has to respect that rather than bridge it rigidly.
- A long sea leg
This is one of the longest routes we run. Ordering to a real schedule matters more here than anywhere else, so we quote the full window.
- Damp and variable climate
PET felt does not absorb moisture, shed fibre or feed mould, which suits cold external walls and sealed rooms.
- Assembly and performance rooms
School halls, marae and community centres carry speech and performance in the same hard room.
04 / Room by room
Space by space, for New Zealand briefs
-
Screen to screen
Independent construction between auditoria, with services broken at the line. Light construction passes low frequency easily. Added mass and a decoupled layer do the work, and absorption alone will not.
- SoundBlanket mass loaded vinyl, 2100 kg per cubic metre
- Acoustic panels, 1800 x 900 mm, image printed into the felt rather than onto a facing
- 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. Seismic detailing means junctions and joints that have to stay flexible. An acoustic build-up has to respect that rather than bridge it rigidly.
- SoundBlanket mass loaded vinyl, STC 30, 5.25 kg per sq m
- Acoustic panels, Cut pattern in PET felt, adds visual rhythm without changing the absorber
- PET felt acoustic panels, 1220 x 2440 mm standard, 4 x 8 ft
-
Plant and projection
Equipment noise into the auditorium, treated at source. This is one of the longest routes we run. Ordering to a real schedule matters more here than anywhere else, so we quote the full window.
- SoundBlanket mass loaded vinyl, STC 34, 8.4 kg per sq m
- Acoustic panels, ASTM C423
- PET felt acoustic panels, 2440 x 4270 mm, 2.44 x 4.27 m, 8 x 14 ft
For a New Zealand interior where the finish leads, we will say plainly what each option costs you acoustically. See how we work with interior designers.
04 / Climate and durability
Durability in New Zealand, before acoustics is discussed
New Zealand is cool and damp, with long heating seasons and cold external walls, and that narrows the material list before acoustics is discussed.
Cold wall build-ups and long heating seasons mean interstitial condensation is a real risk behind any lining. PET felt is unaffected by damp air and will not feed mould where a fabric-faced mineral product would.
The failure we design against here is condensation behind linings in older, poorly insulated stock.
On a New Zealand job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.
06 / Straight talk
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 New Zealand job
Light construction passes low frequency easily. Added mass and a decoupled layer do the work, and absorption alone will not.
05 / Logistics
How material reaches a New Zealand site
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Auckland or Tauranga, then road to site |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Auckland |
| Support | Drawings, build-ups, BOQ and material that arrives complete |
Standard items dispatch in 4 to 7 working days. The sea leg from India is long, so plan the full door to door window into the programme. We give real dates, not optimistic ones.
Sea freight into Auckland or Tauranga, then road to site. Air freight for samples and genuinely urgent quantities.
Questions from New Zealand projects
What makes cinema and multiplex soundproofing different in New Zealand?
School halls, marae and community centres carry speech and performance in the same hard room. Light construction passes low frequency easily. Added mass and a decoupled layer do the work, and absorption alone will not.
Where should the budget go first on a New Zealand 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 New Zealand?
No. We manufacture in India and supply into New Zealand. 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 New Zealand site?
ships from: Palwal, Haryana, India, arrives at: Auckland or Tauranga, then road to site, dispatch: 4 to 7 working days. Standard items dispatch in 4 to 7 working days. The sea leg from India is long, so plan the full door to door window into the programme. We give real dates, not optimistic ones.
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
One drawing gets you a proper answer. Build-up, quantities, a delivered date, and an honest note on anything we think is the wrong approach.
