Acoustic foam and BassBloc in Trivandrum
We manufacture acoustic foam and BassBloc at our own plant at Palwal in Haryana, India, and supply them into Trivandrum. Trivandrum is government and technology in a humid coastal climate, and it is the furthest point in the country from our plant.
- 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 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 / The material
What this material is and where it earns its place in Trivandrum
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 Trivandrum is mostly government and institutional buildings, technology park offices, hospitals, colleges, hotels, auditoriums.
Independent houses with high ceilings, tile floors and open plan layouts built for heat and very heavy monsoon, which rules out anything that absorbs moisture.
- 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 Trivandrum.
02 / Data sheet
One specification sheet, the same in every market
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.
- 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.

What decides the build-up in Trivandrum
- Our longest domestic run
Six days by road. We confirm dates before dispatch and send samples ahead so nothing is decided at the last moment.
- Humidity decides the material
PET felt does not absorb moisture, shed fibre or feed mould. On this coast that is the whole selection argument.
- Technology park floors
Open plans with glass and hard flooring that carry every call across the room.
- Institutional assembly spaces
Large halls in concrete where speech stops being intelligible well before the room sounds wrong.
- The housing stock
Independent houses with high ceilings, tile floors and open plan layouts built for heat and very heavy monsoon, which rules out anything that absorbs moisture.
- 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.
For a Trivandrum practice, the useful thing is a detail you can put in a drawing set, not a brochure. See how we support architects.
04 / Climate and durability
Durability in Trivandrum, before acoustics is discussed
Trivandrum 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.
Designers get colour, pattern and CNC options with the absorption figure attached to each. See how we work with interior designers.
05 / Route to site
How material reaches a Trivandrum site
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | six days |
| Dispatch | 2 to 4 working days |
| To site | six 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 twenty six hundred kilometres, normally six days on a dedicated truck. It is the longest domestic run we operate.
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
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.
-
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 Trivandrum 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
Trivandrum: questions we are actually asked
Do you manufacture acoustic foam and BassBloc in Trivandrum?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Trivandrum as the manufacturer rather than through a dealer. Trivandrum is government and technology in a humid coastal climate, and it is the furthest point in the country from our plant. You buy at factory prices with one consistent batch across the order.
What changes the specification on a Trivandrum job?
Six days by road. We confirm dates before dispatch and send samples ahead so nothing is decided at the last moment. PET felt does not absorb moisture, shed fibre or feed mould. On this coast that is the whole selection argument. Those two things move the build-up far more than the panel figure does.
How does the Trivandrum climate affect this product?
Trivandrum 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.
When would material land on a Trivandrum site?
made at: Our own plant, Palwal, Haryana, reaches site in: six 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.
Is there a minimum order, and how does it arrive?
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.
