Manufactured in India, supplied in Tirupati
Acoustic foam and BassBloc in Tirupati
We manufacture acoustic foam and BassBloc at our own plant at Palwal in Haryana, India, and supply them into Tirupati. Tirupati handles crowds at a scale almost nowhere else does, and that changes what a hall, a queue complex and a guest room have to do.
- 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
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 / What it is
The product, described honestly, for a Tirupati 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 Tirupati is mostly queue and assembly complexes, dining halls, guest accommodation, hotels, hospitals, offices.
RC frame houses and apartments with hard floors, in towns where units share walls and slabs.
- 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 Tirupati.
02 / Specification 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 |
On a Tirupati job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.
03 / On the ground
What the buildings in Tirupati do to the specification
- Designed for continuous crowds
Rooms occupied at capacity around the clock. Announcements have to be understood over a crowd, which is an intelligibility problem first.
- Hard masonry everywhere
Stone, tile and concrete with nothing soft in the room, so reverberation is long and speech suffers.
- Accommodation at volume
Guest rooms in blocks where corridor noise and the next room cause the complaints, not the room itself.
- Four to 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, in towns where units share walls and slabs.
- 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.
For a Tirupati practice, the useful thing is a detail you can put in a drawing set, not a brochure. See how we support architects.
04 / Climate
Why the climate in Tirupati changes the material, not the target
Tirupati 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 / Logistics
Supply into Tirupati, start to site
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | four to five days |
| Dispatch | 2 to 4 working days |
| To site | four to 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 hundred kilometres, normally four to 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
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 Tirupati certification and we will not borrow one. The test data we publish is ours, and we will send the reports rather than describe them.

Tirupati: questions we are actually asked
Is there a Tirupati 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 Tirupati as the manufacturer rather than through a dealer. Tirupati handles crowds at a scale almost nowhere else does, and that changes what a hall, a queue complex and a guest room have to do. You buy at factory prices with one consistent batch across the order.
What changes the specification on a Tirupati job?
Rooms occupied at capacity around the clock. Announcements have to be understood over a crowd, which is an intelligibility problem first. Stone, tile and concrete with nothing soft in the room, so reverberation is long and speech suffers. Those two things move the build-up far more than the panel figure does.
Will this material last in the Tirupati climate?
Tirupati 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 does an order actually travel to Tirupati?
made at: Our own plant, Palwal, Haryana, reaches site in: four to 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.
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.
