01 / The material
What this material is and where it earns its place in Prague
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 Prague is mostly hotel conversions, apartments, production and studio spaces, offices, restaurants, clinics.
Panel block housing has concrete walls with good mass but no impact isolation, while older masonry stock has timber floors that pass footfall.
- 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 Prague.
02 / Data sheet
The published figures, unchanged by location
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
| Density | 2100 kg per cubic metre |
|---|---|
| 2.5 mm | STC 30, 5.25 kg per sq m |
| 4 mm | STC 34, 8.4 kg per sq m |
| 6 mm | 12.6 kg per sq m, STC on request |
| Roll size | 5 x 1.2 m, 6 sq m per roll |
| Form | Limp sheet, cuts with a knife, seams lapped and sealed |
If a consultant has set the target, we will quote against their figures rather than ours, and stay out of the scope they own. More on working with acoustic consultants.
03 / On the ground
The Prague conditions that change the answer
- Protected buildings, internal fixes only
In the centre you often cannot alter the structure or the facade. The work has to be internal, shallow and ideally reversible, which rules out most thick framed systems.
- Conversions into guest rooms
Old buildings divided into hotel rooms and short lets put beds either side of walls that were never separating walls. Door and corridor details cause more complaints than anything else.
- A production city
Stages, edit rooms and post production spaces need the shell to isolate before anything else is decided. There is no partial credit on a room like that.
- Hard stone, long reverberation
Stone, plaster and tile in tall rooms hold sound for a long time. Speech stops being intelligible well before the room sounds obviously wrong.
- The housing stock
Panel block housing has concrete walls with good mass but no impact isolation, while older masonry stock has timber floors that pass footfall.
- The studio and content scene
A strong recording tradition, with rooms fitted into older buildings where the structure helps and the surfaces do not.
For a Prague practice, the useful thing is a detail you can put in a drawing set, not a brochure. See how we support architects.
04 / Durability
What the Prague climate rules in and rules out
Prague 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.
If the visual is fixed and the room still has to perform, that is a solvable problem and a conversation worth having early. See how we work with interior designers.
05 / Logistics
Getting it to Prague, with real dates
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Hamburg, then rail and road into Prague |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Hamburg |
| 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. Grooved panels and custom colours take longer, and we say so before you order, not after.
Sea freight into Hamburg, then rail and road into Prague. 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
The things worth knowing before you place the order
-
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.
-
A number chased without a measurement
If nobody has measured the room or set a target, the specification is a guess with a decimal point in it. We will ask for the target before we quote the quantity.
-
Local approvals that nobody actually holds
We hold no Prague certification and we will not borrow one. The test data we publish is ours, and we will send the reports rather than describe them.
Prague: questions we are actually asked
Where are the soundBlanket mass loaded vinyl you supply to Prague actually made?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Prague as the manufacturer rather than through a dealer. Made at our own plant in India and shipped into Hamburg, then rail and road into the city, with the inland leg written into the dates we quote. You buy at factory prices with one consistent batch across the order.
What changes the specification on a Prague job?
In the centre you often cannot alter the structure or the facade. The work has to be internal, shallow and ideally reversible, which rules out most thick framed systems. Old buildings divided into hotel rooms and short lets put beds either side of walls that were never separating walls. Door and corridor details cause more complaints than anything else. Those two things move the build-up far more than the panel figure does.
Is this the right material for Prague conditions?
Prague 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 Prague?
ships from: Palwal, Haryana, India, arrives at: Hamburg, then rail and road into Prague, dispatch: 4 to 7 working days. Standard items dispatch in 4 to 7 working days. Grooved panels and custom colours take longer, and we say so before you order, not after.
What will soundBlanket mass loaded vinyl 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.
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.
