Acoustic foam and BassBloc in Visakhapatnam
We manufacture acoustic foam and BassBloc at our own plant at Palwal in Haryana, India, and supply them into Visakhapatnam. Visakhapatnam is a port and a steel city on a cyclone coast, which means heavy industry and a climate that destroys the wrong material.
- 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
We make this ourselves and ship it to you. No local branch, no borrowed certifications, no dealer margin. One batch across the whole order, and an honest answer when the product is wrong for the problem.
01 / The material
What this material is and where it earns its place in Visakhapatnam
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 Visakhapatnam is mostly steel and port industry, control rooms, offices, hospitals, colleges, hotels.
RC frame houses and apartments with hard floors, in towns where units share walls and slabs.
- 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 Visakhapatnam.
02 / Data sheet
The published figures, unchanged by location
We publish one data sheet for every market. If a supplier quotes you a different figure for the same product in a different city, one of the two numbers is wrong.
- 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 |
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 / In this market
What the buildings in Visakhapatnam do to the specification
- Heavy industry, low frequency
Mills, blowers and compressors put energy into the structure. Mass, isolation and enclosure are the only things that address it.
- Control rooms run long shifts
Operators listening for alarms need a low background before anything else matters.
- Salt air and cyclone coast
PET felt does not absorb moisture, rot or corrode, which matters where mineral products fail within a couple of seasons.
- Four days by road
A long run, confirmed before dispatch, with samples sent ahead of the order.
- The housing stock
RC frame houses and apartments with hard floors, in towns where units share walls and slabs.
- The studio and content scene
Studios go into basements, terrace rooms and back rooms with neighbours on every side and a generator somewhere in the lane. Isolating from the building has to come before treating the room.
If you are specifying for a Visakhapatnam project, we can give you a section, a BOQ and the honest limits of each layer. See how we support architects.
04 / Durability
The Visakhapatnam climate decides the material list
Visakhapatnam is warm and humid through most of the year, with a long wet season, and that narrows the sensible material list before acoustics is even discussed.
Humidity is the deciding factor. PET felt does not absorb moisture, shed fibre or feed mould, which is why it outlasts fabric-wrapped mineral wool in this climate. Wood wool and timber need a ventilated cavity behind them.
The risk we design against here is mould, sagging fabric finishes and swelling in timber.
For a Visakhapatnam interior where the finish leads, we will say plainly what each option costs you acoustically. See how we work with interior designers.
05 / Logistics
How material reaches a Visakhapatnam site
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | four days |
| Dispatch | 2 to 4 working days |
| To site | four days |
| Packing | Compressed and boxed for foam, palletised flat for BassBloc. |
| Lead time | 4 to 7 working days. |
Standard items dispatch in 2 to 4 working days from our plant at Palwal. Grooved panels and custom colours take longer, and we say so before you order, not after.
By road from Palwal, roughly eighteen hundred kilometres, normally four days on a dedicated truck.
200 sq ft for acoustic foam, 300 sq ft for BassBloc, 10 pieces for bass traps.
| 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
Where this goes wrong, said plainly
-
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.
-
Square footage quoted before the room is understood
Anyone can price a wall. Working out how much material the room actually needs usually reduces the order, which is why not everyone does it.
-
Local approvals that nobody actually holds
We hold no Visakhapatnam 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
Visakhapatnam: questions we are actually asked
Is there a Visakhapatnam 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 Visakhapatnam as the manufacturer rather than through a dealer. Visakhapatnam is a port and a steel city on a cyclone coast, which means heavy industry and a climate that destroys the wrong material. You buy at factory prices with one consistent batch across the order.
What changes the specification on a Visakhapatnam job?
Mills, blowers and compressors put energy into the structure. Mass, isolation and enclosure are the only things that address it. Operators listening for alarms need a low background before anything else matters. Those two things move the build-up far more than the panel figure does.
Does Visakhapatnam weather shorten the life of this material?
Visakhapatnam is warm and humid through most of the year, with a long wet season. Humidity is the deciding factor. PET felt does not absorb moisture, shed fibre or feed mould, which is why it outlasts fabric-wrapped mineral wool in this climate. Wood wool and timber need a ventilated cavity behind them. The failure we design against here is mould, sagging fabric finishes and swelling in timber.
How does an order actually travel to Visakhapatnam?
made at: Our own plant, Palwal, Haryana, reaches site in: four days, dispatch: 2 to 4 working days. Standard items dispatch in 2 to 4 working days from our plant at Palwal. Grooved panels and custom colours take longer, and we say so before you order, not after.
What should you not buy acoustic foam and BassBloc for?
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?
200 sq ft for acoustic foam, 300 sq ft for BassBloc, 10 pieces for bass traps. 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.
