Manufactured in India, supplied in Madurai
Acoustic foam and BassBloc in Madurai
We manufacture acoustic foam and BassBloc at our own plant at Palwal in Haryana, India, and supply them into Madurai. Madurai is a temple city with a textile base, in dry heat, and most of the work is very large rooms handling very large numbers of people.

- Made at our own plant, Palwal, Haryana, India
- One batch across the order, no blending between runs

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 / Start here
The product, described honestly, for a Madurai brief
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 Madurai is mostly assembly and dining halls, hotels, textile units, colleges, hospitals, offices.
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 Madurai.
02 / The numbers
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 |
| BassBloc NRC | 0.85 |
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 / Local conditions
What the buildings in Madurai do to the specification
- Very large assembly spaces
Halls holding continuous crowds in hard stone and concrete, where intelligibility fails long before the room sounds obviously wrong.
- Textile machinery
Continuous machine noise in units close to housing. Enclosure at the source rather than lining the hall.
- Dry heat
PET felt does not sag, shed fibre or degrade at high temperature, which matters in roof voids and sealed conditioned rooms.
- 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.
Architects working in Madurai usually need the build-up before the product. We will draw the section and mark what does the work. See how we support architects.
04 / Climate
The Madurai climate decides the material list
Madurai 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 / Supply
How material reaches a Madurai site
| 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 four 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 / Worth knowing
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 Madurai certification and we will not borrow one. The test data we publish is ours, and we will send the reports rather than describe them.

How it looks once it is installed
Madurai: questions we are actually asked
Is there a Madurai 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 Madurai as the manufacturer rather than through a dealer. Madurai is a temple city with a textile base, in dry heat, and most of the work is very large rooms handling very large numbers of people. You buy at factory prices with one consistent batch across the order.
What decides the specification for a Madurai project?
Halls holding continuous crowds in hard stone and concrete, where intelligibility fails long before the room sounds obviously wrong. Continuous machine noise in units close to housing. Enclosure at the source rather than lining the hall. Those two things move the build-up far more than the panel figure does.
Will this material last in the Madurai climate?
Madurai 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 quickly can material reach a site in Madurai?
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.
When are acoustic foam and BassBloc the wrong purchase?
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.
How is the order packed and what is the minimum?
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.
