Manufactured in India, supplied in Vellore
Acoustic foam and BassBloc in Vellore
We manufacture acoustic foam and BassBloc at our own plant at Palwal in Haryana, India, and supply them into Vellore. Vellore is dominated by medical and engineering institutions, which makes clinical privacy and lecture intelligibility the two recurring briefs.
- 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 / What it is
The material, and what it actually does on a Vellore job
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 Vellore is mostly teaching hospitals, engineering campuses, lecture theatres, hostels, offices, hotels.
RC frame houses and apartments with hard floors, built for heat and humidity with open plan layouts that carry sound room to room.
- 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 Vellore.
02 / Specification sheet
Published specification, identical wherever we ship it
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 |

On a Vellore job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.
03 / Local conditions
What decides the build-up in Vellore
- Clinical privacy
Consult and counselling rooms where conversations must not carry. That is a partition and door question before it is a panel question.
- Lecture theatres
Large teaching rooms where every seat has to hear clearly, usually in concrete and tile.
- Hostels and residences
Students living next to each other and to corridors, where separating detail does the work.
- Five 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, built for heat and humidity with open plan layouts that carry sound room to room.
- 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.
We would rather argue about the build-up at design stage than on site. See how we support architects.
04 / Climate
Durability in Vellore, before acoustics is discussed
Vellore 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.
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 / Supply
Getting it to Vellore, with real dates
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | five days |
| Dispatch | 2 to 4 working days |
| To site | five 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 two hundred kilometres, normally five 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
Four honest warnings before you buy
-
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.
-
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 Vellore certification and we will not borrow one. The test data we publish is ours, and we will send the reports rather than describe them.
07 / In projects
The material in real interiors
Vellore: questions we are actually asked
Where are the acoustic foam and BassBloc you supply to Vellore actually made?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Vellore as the manufacturer rather than through a dealer. Vellore is dominated by medical and engineering institutions, which makes clinical privacy and lecture intelligibility the two recurring briefs. You buy at factory prices with one consistent batch across the order.
Why would a Vellore build-up differ from anywhere else?
Consult and counselling rooms where conversations must not carry. That is a partition and door question before it is a panel question. Large teaching rooms where every seat has to hear clearly, usually in concrete and tile. Those two things move the build-up far more than the panel figure does.
Does Vellore weather shorten the life of this material?
Vellore 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.
What is the delivery time into Vellore?
made at: Our own plant, Palwal, Haryana, reaches site in: five 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.
Where do acoustic foam and BassBloc fail to help?
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.
