Manufactured in India, supplied in Auckland
SoundBlanket mass loaded vinyl in Auckland
We manufacture soundBlanket mass loaded vinyl at our own plant at Palwal in Haryana, India, and supply them into Auckland. Made at our own plant in India and shipped straight into Auckland, so the container arrives at the city rather than a long domestic leg away.

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 / What it is
The product, described honestly, for a Auckland brief
A limp, high density sheet that adds mass to a partition, floor or duct without adding depth. It is the barrier product, not an absorber, and it is the right answer when the problem is noise passing through a structure.
Work reaching us from Auckland is mostly apartments and townhouses, offices, hospitality, 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.
- Wall, decoupled Independent stud, membrane between the boards, cavity absorption, two boards. The membrane is one part of a system, never the whole answer.
- Floor, floating Membrane under a resilient layer and a floating deck, so impact energy is broken before it reaches the slab.
- Duct and plant wrap Membrane wrapped over the duct with a decoupling layer beneath, sealed at every lap.
- What it will not do Mass fixed hard to an existing wall gives far less than the same mass on an independent leaf. If we are told the wall cannot be thickened, we will say what the membrane will and will not achieve rather than quote the laboratory figure and let the site find out.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for SoundBlanket MLV are on the main product page. This page covers what that means for a project in Auckland.
02 / The numbers
Published specification, identical wherever we ship it
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.
- 2.5 mmSTC 30, 5.25 kg per sq m. Ducts, light partitions, retrofit where depth is tight
- 4 mmSTC 34, 8.4 kg per sq m. Party walls, floors, plant rooms, the common specification
- 6 mm12.6 kg per sq m. Machine enclosures and low frequency problems

Where a consultant is already engaged on a Auckland project, we supply to their specification and send the test reports rather than describing them. More on working with acoustic consultants.
03 / On the ground
The Auckland conditions that change the answer
- Apartments built light and fast
Townhouse and apartment stock built quickly in timber frame. The separating construction is where noise complaints concentrate.
- Weathertightness shapes the build-up
Wall assemblies here are designed around drainage and drying. An acoustic layer has to work with that, not trap moisture in it.
- Volcanic ground, seismic detailing
Flexible junctions are required, so a rigid acoustic bridge across a movement joint is not acceptable.
- The port is in the city
Direct sea into Auckland keeps the road leg short, though the sea leg itself is long and we quote it fully.
- 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.
- The studio and content scene
Project studios go into garages and sleepouts in timber framed housing that leaks at every junction.
For a Auckland practice, the useful thing is a detail you can put in a drawing set, not a brochure. See how we support architects.
04 / Conditions
Why the climate in Auckland changes the material, not the target
Auckland 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.
For a Auckland interior where the finish leads, we will say plainly what each option costs you acoustically. See how we work with interior designers.
05 / Supply
Getting it to Auckland, with real dates
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Auckland, then a short road run to site |
| Dispatch | 4 to 7 working days |
| Freight | Sea into Auckland |
| Packing | Rolls on core tubes, wrapped and end capped, 5 x 1.2 m. Weights on the packing list, because a full roll is heavy and site access matters. |
| Lead time | 4 to 7 working days. Full container quantities scheduled against the vessel. |
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 direct into Auckland, then a short road run to site. Air freight for samples and urgent quantities.
The same minimums apply on export as on domestic orders.
| 2.5 mm and 4 mm | 10 rolls, 60 sq m |
|---|---|
| 6 mm and other thicknesses | 10 tonnes per thickness |
A SoundBlanket roll is 5 x 1.2 m, which is 6 sq m. At 2100 kg per cubic metre a roll weighs about 31.5 kg at 2.5 mm and about 50.4 kg at 4 mm, so a 10 roll minimum is 60 sq m and roughly 315 kg at 2.5 mm or 504 kg at 4 mm.
06 / Before you buy
Four honest warnings before you buy
-
The wrong product for the problem
Mass fixed hard to an existing wall gives far less than the same mass on an independent leaf. If we are told the wall cannot be thickened, we will say what the membrane will and will not achieve rather than quote the laboratory figure and let the site find out.
-
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 Auckland certification and we will not borrow one. The test data we publish is ours, and we will send the reports rather than describe them.
Auckland: questions we are actually asked
Is there a Auckland factory behind this product?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Auckland as the manufacturer rather than through a dealer. Made at our own plant in India and shipped straight into Auckland, so the container arrives at the city rather than a long domestic leg away. You buy at factory prices with one consistent batch across the order.
What changes the specification on a Auckland job?
Townhouse and apartment stock built quickly in timber frame. The separating construction is where noise complaints concentrate. Wall assemblies here are designed around drainage and drying. An acoustic layer has to work with that, not trap moisture in it. Those two things move the build-up far more than the panel figure does.
Is this the right material for Auckland conditions?
Auckland 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.
How does an order actually travel to Auckland?
ships from: Palwal, Haryana, India, arrives at: Auckland, then a short road run 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.
Where do soundBlanket mass loaded vinyl fail to help?
Mass fixed hard to an existing wall gives far less than the same mass on an independent leaf. If we are told the wall cannot be thickened, we will say what the membrane will and will not achieve rather than quote the laboratory figure and let the site find out.
How is the order packed and what is the minimum?
The same minimums apply on export as on domestic orders. 2.5 mm and 4 mm, 10 rolls, 60 sq m. 6 mm and other thicknesses, 10 tonnes per thickness. A SoundBlanket roll is 5 x 1.2 m, which is 6 sq m. At 2100 kg per cubic metre a roll weighs about 31.5 kg at 2.5 mm and about 50.4 kg at 4 mm, so a 10 roll minimum is 60 sq m and roughly 315 kg at 2.5 mm or 504 kg at 4 mm. Rolls on core tubes, wrapped and end capped, 5 x 1.2 m. Weights on the packing list, because a full roll is heavy and site access matters.
