- 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 Prayagraj
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 Prayagraj is mostly coaching institutes, courtrooms, colleges, auditoriums, assembly halls, offices, clinics.
Independent houses and builder flats in brick and RC frame, often built floor by floor for different households, so the slab between them was never detailed as a separation.
- 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 Prayagraj.
02 / Specification sheet
The published figures, unchanged by location
These figures are published and they do not move. The thing worth arguing about is not the number on the sheet, it is which grade and which build-up suits the room you are treating.
- 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 Prayagraj project, we supply to their specification and send the test reports rather than describing them. More on working with acoustic consultants.
03 / Local conditions
The Prayagraj conditions that change the answer
- Rooms built for listening
Coaching halls and lecture rooms pack people into hard spaces. Intelligibility fails long before anyone describes the room as echoing.
- Courtrooms and hearing spaces
Every word has to be understood and recorded. That needs controlled absorption and a low background, in that order.
- Large assembly at scale
Very large halls hold sound for a long time. Absorption has to be placed where it recovers speech, not spread evenly to hit a number.
- Two to three days by road
A dedicated truck from Palwal, and samples ahead of the order so the finish is approved first.
- The housing stock
Independent houses and builder flats in brick and RC frame, often built floor by floor for different households, so the slab between them was never detailed as a separation.
- 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 Prayagraj 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 / Durability
What the Prayagraj climate rules in and rules out
Prayagraj 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.
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 Prayagraj, with real dates
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | two to three days |
| Dispatch | 2 to 4 working days |
| To site | two to 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 seven hundred and fifty kilometres, normally two to 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
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 Prayagraj 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 material in real interiors
Prayagraj: questions we are actually asked
Is there a Prayagraj 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 Prayagraj as the manufacturer rather than through a dealer. Prayagraj is a city of rooms full of people listening. You buy at factory prices with one consistent batch across the order.
What do you look at first on a Prayagraj enquiry?
Coaching halls and lecture rooms pack people into hard spaces. Intelligibility fails long before anyone describes the room as echoing. Every word has to be understood and recorded. That needs controlled absorption and a low background, in that order. Those two things move the build-up far more than the panel figure does.
Does Prayagraj weather shorten the life of this material?
Prayagraj 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 Prayagraj?
made at: Our own plant, Palwal, Haryana, reaches site in: two to 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 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.
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.
