Manufactured in India, supplied in Ranchi
Acoustic foam and BassBloc in Ranchi
We manufacture acoustic foam and BassBloc at our own plant at Palwal in Haryana, India, and supply them into Ranchi. Ranchi is a state capital on a plateau, with mining sector offices and a growing institutional sector rather than heavy plant inside the city.

- 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

- 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
This comes from our own plant, not a trading desk. We do not have an office in your city and we will not invent one. What we can give you is factory pricing, consistent material and a technical answer before you commit.
01 / The product
What this material is and where it earns its place in Ranchi
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 Ranchi is mostly government and institutional buildings, colleges, hospitals, corporate offices, auditoriums, hotels.
RC frame apartments and houses with hard floors, in towns built around mining and steel activity.
- 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 Ranchi.
02 / Specification
One specification sheet, the same in every market
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 |
Where a consultant is already engaged on a Ranchi project, we supply to their specification and send the test reports rather than describing them. More on working with acoustic consultants.
03 / What drives the brief
The Ranchi conditions that change the answer
- Rooms built for listening
Assembly halls and lecture theatres in hard finishes defeat the speaker long before anyone calls the room echoey.
- New institutional build
Concrete and tile put up quickly, with the acoustic problem discovered at handover rather than designed out.
- Corporate and regional offices
Open floors with glass cabins where calls carry and meeting rooms sound hollow.
- Three days by road
A dedicated truck from Palwal, confirmed before dispatch, with samples sent ahead.
- The housing stock
RC frame apartments and houses with hard floors, in towns built around mining and steel activity.
- 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 Ranchi 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
What the Ranchi climate rules in and rules out
Ranchi is hot summers, mild winters and a distinct wet season, and that narrows the sensible material list before acoustics is even discussed.
PET felt handles the wet months without absorbing moisture or feeding mould. Timber and wood wool want a ventilated cavity and a stable indoor RH.
The risk we design against here is wet-season humidity behind linings.
Designers get colour, pattern and CNC options with the absorption figure attached to each. See how we work with interior designers.
05 / Supply
Getting it to Ranchi, with real dates
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | three days |
| Dispatch | 2 to 4 working days |
| To site | three 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 twelve hundred kilometres, normally three 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.
-
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.
-
Suppliers who imply a Ranchi presence
Ask any supplier where the material is made and who carries the warranty. We make it at Palwal in Haryana and we say so on every page, including this one.

The product on finished jobs
Ranchi: questions we are actually asked
Are these acoustic foam and BassBloc made in Ranchi?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Ranchi as the manufacturer rather than through a dealer. Ranchi is a state capital on a plateau, with mining sector offices and a growing institutional sector rather than heavy plant inside the city. You buy at factory prices with one consistent batch across the order.
What decides the specification for a Ranchi project?
Assembly halls and lecture theatres in hard finishes defeat the speaker long before anyone calls the room echoey. Concrete and tile put up quickly, with the acoustic problem discovered at handover rather than designed out. Those two things move the build-up far more than the panel figure does.
Will this material last in the Ranchi climate?
Ranchi is hot summers, mild winters and a distinct wet season. PET felt handles the wet months without absorbing moisture or feeding mould. Timber and wood wool want a ventilated cavity and a stable indoor RH. The failure we design against here is wet-season humidity behind linings.
What is the delivery time into Ranchi?
made at: Our own plant, Palwal, Haryana, reaches site in: three 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 will acoustic foam and BassBloc not do?
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.

Send the drawings, get a straight answer
A plan and a section is enough. We will come back with a build-up, a BOQ and a delivered date, and we will say so if what you are asking for will not work.
