- One batch across the order, no blending between runs
We are the manufacturer. There is no local office and we do not claim approvals we do not hold. What you get is factory pricing, one consistent batch across the order, and a straight answer on what the material will and will not do.
01 / The product
What this material is and where it earns its place in New Zealand
The blocking side of the range taken together: mass loaded vinyl, resilient layers, cavity absorption and the build-ups they belong in. This is the page for someone whose problem is noise getting through, not a room that sounds wrong.
Work reaching us from New Zealand is mostly timber frame housing, apartments, offices, schools, clinics, studios.
Timber frame with plasterboard linings, so walls have very little mass. Apartment and townhouse party walls need a second leaf rather than surface treatment.
- Independent leaf A second wall that does not touch the first. Nothing else comes close for the money.
- Resilient bar Where a full independent leaf will not fit. Effective, and very easy to short circuit with one wrong screw.
- Floating floor Resilient layer and deck, to break impact energy before it reaches the structure.
- What it will not do Soundproofing fails at the gaps, not the materials. A service penetration, a back to back socket, or a door undercut will undo a correctly built wall.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for our soundproofing materials are on the main product page. This page covers what that means for a project in New Zealand.

02 / Specification
The numbers, and they do not move by city
Nothing below changes by location. The decisions that do change are grade, thickness and how the material is mounted, and those are covered further down.
- Light retrofit2.5 mm membrane. Where depth is not available
- Standard partition4 mm membrane on an independent leaf. The common specification
- Heavy6 mm membrane and full decoupling. Plant, machine enclosure, low frequency

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.
03 / On the ground
What decides the build-up in New Zealand
- 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.
- Plant and HVAC
Heat pumps and ducted systems, with outdoor units close to boundaries in dense suburbs.
- The housing stock
Timber frame with plasterboard linings, so walls have very little mass. Apartment and townhouse party walls need a second leaf rather than surface treatment.
Architects working in New Zealand usually need the build-up before the product. We will draw the section and mark what does the work. See how we support architects.
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 sensible material list before acoustics is even 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 risk we design against here is condensation behind linings in older, poorly insulated stock.
Designers get colour, pattern and CNC options with the absorption figure attached to each. See how we work with interior designers.
05 / Route to site
Getting it to New Zealand, with real dates
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Auckland or Tauranga, then road to site |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Auckland |
| Packing | Rolls on core tubes, boards palletised, fixings and tapes listed on the same packing list. |
| Lead time | 4 to 7 working days for stock items. |
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.
06 / Before you buy
What we will tell you that a reseller will not
-
The wrong product for the problem
Soundproofing fails at the gaps, not the materials. A service penetration, a back to back socket, or a door undercut will undo a correctly built wall. We would rather spend the conversation on the detail than on the product.
-
Coverage bought instead of a target
Lining every surface is a purchase, not a result. We would rather calculate the area against a reverberation target and sell you less of it.
-
Local approvals that nobody actually holds
We hold no New Zealand certification and we will not borrow one. The test data we publish is ours, and we will send the reports rather than describe them.

The material in real interiors
New Zealand: questions we are actually asked
Do you manufacture soundproofing materials in New Zealand?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into New Zealand as the manufacturer rather than through a dealer. Made at our own plant in India and shipped into Auckland or Tauranga. You buy at factory prices with one consistent batch across the order.
What decides the specification for a New Zealand project?
Light construction passes low frequency easily. Added mass and a decoupled layer do the work, and absorption alone will not. Seismic detailing means junctions and joints that have to stay flexible. An acoustic build-up has to respect that rather than bridge it rigidly. Those two things move the build-up far more than the panel figure does.
Is this the right material for New Zealand conditions?
New Zealand is cool and damp, with long heating seasons and cold external walls. 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.
When would material land on 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 should you not buy soundproofing materials for?
Soundproofing fails at the gaps, not the materials. A service penetration, a back to back socket, or a door undercut will undo a correctly built wall. We would rather spend the conversation on the detail than on the product.
How is the order packed and what is the minimum?
Minimum order is confirmed with the quote. Rolls on core tubes, boards palletised, fixings and tapes listed on the same packing list.
Next step
Send a plan and a section, get a real build-up
We quote from drawings, not from a square foot rate. Send a plan and the section through the critical wall or ceiling and you will get something you can actually build from.
