Manufactured in India, supplied in Sweden
Acoustic foam and BassBloc in Sweden
We manufacture acoustic foam and BassBloc at our own plant at Palwal in Haryana, India, and supply them into Sweden. Made at our own plant in India and shipped into Gothenburg, then road onward, with the domestic leg quoted separately because Sweden is a long country.
- BassBloc size
- 1800 x 900 mm
- BassBloc thickness
- 20 mm
- BassBloc density
- 100 kg per cubic metre
- Effective range
- 100 to 500 Hz
- BassBloc NRC
- 0.85
- Lead time
- 4 to 7 working days
- Minimum order
- From 200 sq ft
- Made at our own plant, Palwal, Haryana, India
- One batch across the order, no blending between runs
- Test reports sent on request, not just quoted
Manufacturer, not reseller. We hold no local approvals and will not imply we do. You get the price the factory quotes, material that matches across a large order, and advice that sometimes talks you out of a purchase.
01 / The material
What this is, and what it changes in a Sweden room
Open cell foam shapes for high frequency control, and BassBloc, a high density absorber built for the low mid range where ordinary foam does nothing.
Work reaching us from Sweden is mostly timber buildings and apartments, offices, schools, healthcare, hotels, studios.
Concrete apartment blocks and timber frame housing with tight envelopes, hard floors and cold external walls.
- Corner loading Low frequency energy collects in corners, so absorber in the corners does more than the same area spread across a wall.
- First reflection points Mirror trick placement on side walls and ceiling, which is a handful of panels rather than a lined room.
- Behind a fabric frame Where the room has to look finished, absorber inside a frame rather than foam on show.
- What it will not do Thin foam on a wall is the most over-sold product in this industry. It controls flutter and nothing below it.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for acoustic foam and bass traps are on the main product page. This page covers what that means for a project in Sweden.
02 / The numbers
Published specification, identical wherever we ship it
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.
- Foam wedge and pyramidLow density. Flutter and high frequency only
- BassBloc100 kg per cubic metre. Low mid absorption, control rooms, live rooms
| BassBloc size | 1800 x 900 mm |
|---|---|
| BassBloc thickness | 20 mm |
| BassBloc density | 100 kg per cubic metre |
| Effective range | 100 to 500 Hz |
| BassBloc NRC | 0.85 |
On a Sweden job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.
03 / Local conditions
What the buildings in Sweden do to the specification
- Classes are written and verified
Projects arrive with a class and someone checks it afterwards. Send us the target and we will say where our material sits against it.
- Timber at scale
Sweden builds tall in timber, and timber is light. Low frequency passes easily, so mass and decoupling do the work.
- Sealed through a long winter
Ventilation runs constantly in closed buildings, so plant noise matters more than street noise.
- A long country
A site in the north has a real domestic leg. We quote it separately so the dates are honest.
- The housing stock
Concrete apartment blocks and timber frame housing with tight envelopes, hard floors and cold external walls.
- The studio and content scene
A very deep music production culture where absorption data and measured targets are expected.
We would rather argue about the build-up at design stage than on site. See how we support architects.
04 / Climate and durability
The Sweden climate decides the material list
Sweden 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 Sweden interior where the finish leads, we will say plainly what each option costs you acoustically. See how we work with interior designers.
05 / Getting it there
Supply into Sweden, start to site
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Gothenburg, then road onward to site |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Gothenburg |
| Packing | Compressed and boxed for foam, palletised flat for BassBloc. |
| Lead time | 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.
Sea freight into Gothenburg, then road onward to site. Air freight for samples and urgent quantities.
The same minimums apply on export.
| Acoustic foam | 200 sq ft, about 19 sq m |
|---|---|
| BassBloc | 300 sq ft, about 28 sq m |
| Bass traps | 10 pieces |
A BassBloc panel is 1800 x 900 mm, which is 1.62 sq m or about 17.4 sq ft, so the BassBloc minimum is roughly 17 panels.
06 / Before you buy
The things worth knowing before you place the order
-
The wrong product for the problem
Thin foam on a wall is the most over-sold product in this industry. It controls flutter and nothing below it. If the complaint is boom, bass from a neighbour, or a room that sounds uneven at low frequency, foam is the wrong purchase and we will say so.
-
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 Sweden 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 product on finished jobs
Sweden: questions we are actually asked
Where are the acoustic foam and BassBloc you supply to Sweden actually made?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Sweden as the manufacturer rather than through a dealer. Made at our own plant in India and shipped into Gothenburg, then road onward, with the domestic leg quoted separately because Sweden is a long country. You buy at factory prices with one consistent batch across the order.
What changes the specification on a Sweden job?
Projects arrive with a class and someone checks it afterwards. Send us the target and we will say where our material sits against it. Sweden builds tall in timber, and timber is light. Low frequency passes easily, so mass and decoupling do the work. Those two things move the build-up far more than the panel figure does.
Is this the right material for Sweden conditions?
Sweden 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 Sweden?
ships from: Palwal, Haryana, India, arrives at: Gothenburg, then road onward 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 will acoustic foam and BassBloc not do?
Thin foam on a wall is the most over-sold product in this industry. It controls flutter and nothing below it. If the complaint is boom, bass from a neighbour, or a room that sounds uneven at low frequency, foam is the wrong purchase and we will say so.
What is the minimum order and how is it packed?
The same minimums apply on export. Acoustic foam, 200 sq ft, about 19 sq m. BassBloc, 300 sq ft, about 28 sq m. Bass traps, 10 pieces. A BassBloc panel is 1800 x 900 mm, which is 1.62 sq m or about 17.4 sq ft, so the BassBloc minimum is roughly 17 panels. Compressed and boxed for foam, palletised flat for BassBloc.

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.
