Manufactured in India, supplied in Montreal
SoundBlanket mass loaded vinyl in Montreal
We manufacture soundBlanket mass loaded vinyl at our own plant at Palwal in Haryana, India, and supply them into Montreal. Made at our own plant in India and shipped up the St Lawrence into the Port of Montreal, which puts the container inside the city rather than a province 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 material, and what it actually does on a Montreal job
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 Montreal is mostly plex and condo housing, studios and rehearsal rooms, offices, restaurants, schools, clinics.
Timber frame with gypsum board in low rise, concrete in towers. Condominium party walls and floors generate most complaints, and impact noise through a concrete slab needs a resilient layer, not a panel.
- 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.

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 Montreal.
02 / Data sheet
The numbers, and they do not move by city
These figures are published and they do not move. The thing worth arguing about is not the number on the sheet, it is which grade and which build-up suits the room you are treating.
- 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 Montreal project, we supply to their specification and send the test reports rather than describing them. More on working with acoustic consultants.
03 / In this market
What decides the build-up in Montreal
- Plex floors pass everything
Stacked flats with timber joists send footfall and speech straight down. A resilient layer under the new floor does more than any ceiling treatment below it.
- A city that makes a lot of noise on purpose
Rehearsal rooms, studios and practice spaces in residential buildings are normal here. Isolation is what keeps them viable, not absorption.
- The port is in the city
Containers come up the St Lawrence and land in Montreal itself, which keeps the road leg short and the landed cost predictable.
- Long sealed winters
Buildings close up for months and mechanical systems run hard. Noise stops escaping and accumulates inside instead.
- The housing stock
Timber frame with gypsum board in low rise, concrete in towers. Condominium party walls and floors generate most complaints, and impact noise through a concrete slab needs a resilient layer, not a panel.
- The studio and content scene
Basement and garage studios are common, and a finished basement ceiling with no decoupling passes everything to the floor above.
For a Montreal practice, the useful thing is a detail you can put in a drawing set, not a brochure. See how we support architects.
04 / Conditions
Durability in Montreal, before acoustics is discussed
Montreal 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 Montreal 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 Montreal, with real dates
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Port of Montreal, then a short road run to site |
| Dispatch | 4 to 7 working days |
| Freight | Sea into Port of Montreal |
| 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 into the Port of Montreal, 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 / Straight talk
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 Montreal certification and we will not borrow one. The test data we publish is ours, and we will send the reports rather than describe them.
Montreal: questions we are actually asked
Is there a Montreal 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 Montreal as the manufacturer rather than through a dealer. Made at our own plant in India and shipped up the St Lawrence into the Port of Montreal, which puts the container inside the city rather than a province away. You buy at factory prices with one consistent batch across the order.
What decides the specification for a Montreal project?
Stacked flats with timber joists send footfall and speech straight down. A resilient layer under the new floor does more than any ceiling treatment below it. Rehearsal rooms, studios and practice spaces in residential buildings are normal here. Isolation is what keeps them viable, not absorption. Those two things move the build-up far more than the panel figure does.
Is this the right material for Montreal conditions?
Montreal 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 quickly can material reach a site in Montreal?
ships from: Palwal, Haryana, India, arrives at: Port of Montreal, 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.
When are soundBlanket mass loaded vinyl the wrong purchase?
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.
What quantity do we have to order, and in what packaging?
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.
