Acoustic foam and BassBloc in Coimbatore
We manufacture acoustic foam and BassBloc at our own plant at Palwal in Haryana, India, and supply them into Coimbatore. Coimbatore makes pumps, motors and textile machinery, which means test rooms and shop floors rather than interiors.
- 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 / Start here
The product, described honestly, for a Coimbatore 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 Coimbatore is mostly engineering plants and test rooms, colleges, textile units, hospitals, 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 Coimbatore.
02 / Data sheet
The published figures, unchanged by location
The specification below is the same everywhere we supply, because a specification that changed by city would not be a specification. What changes is which grade and build-up is the right buy, and that is what the rest of this page is about.
- 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 decides the build-up in Coimbatore
- Test and measurement rooms
Motor and pump testing needs a genuinely low background before any reading means anything. That is isolation with a written target, not absorption.
- Foundry and machining noise
Low frequency and structure-borne. Enclosure at the source rather than treating the hall.
- Education at scale
A large college sector with lecture rooms and hostels where speech fails and noise between rooms is constant.
- Dry inland climate
PET felt is stable in dry heat and does not shed fibre, which suits sealed conditioned rooms.
- 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 and durability
The Coimbatore climate decides the material list
Coimbatore 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 Coimbatore interior where the finish leads, we will say plainly what each option costs you acoustically. See how we work with interior designers.
05 / Supply
Getting it to Coimbatore, 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 three 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
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.
-
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.
-
A claim of being local to Coimbatore
We manufacture in India and supply here. We do not run an office in this city and we will not pretend to, because you would find out on the first site visit.
07 / In projects
The material in real interiors
Coimbatore: questions we are actually asked
Are these acoustic foam and BassBloc made in Coimbatore?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Coimbatore as the manufacturer rather than through a dealer. Coimbatore makes pumps, motors and textile machinery, which means test rooms and shop floors rather than interiors. You buy at factory prices with one consistent batch across the order.
What changes the specification on a Coimbatore job?
Motor and pump testing needs a genuinely low background before any reading means anything. That is isolation with a written target, not absorption. Low frequency and structure-borne. Enclosure at the source rather than treating the hall. Those two things move the build-up far more than the panel figure does.
Does Coimbatore weather shorten the life of this material?
Coimbatore 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 Coimbatore?
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.
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 quantity do we have to order, and in what packaging?
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.
