01 / Start here
What this is, and what it changes in a Kolkata room
Timber slats on an acoustic backing. The slats are the finish and the rhythm, the backing does the absorbing. Used where the room has to look considered rather than treated.
Work reaching us from Kolkata is mostly old buildings and conversions, offices, clubs and restaurants, schools, clinics, auditoriums.
Older masonry buildings and newer RC frame apartments with hard floors, in very dense neighbourhoods with heavy monsoon damp.
- Slats on felt backing The standard. Absorption comes from the backing behind the gaps, so the slat gap ratio is an acoustic decision, not only a visual one.
- Slats on a cavity Backing plus an air gap behind moves absorption lower, which matters in music rooms.
- Feature wall only Slats where they are seen, plain felt elsewhere, to hold the budget where it shows.
- What it will not do A tight slat pattern looks denser but absorbs less, because the open area is what lets sound reach the backing. If the visual you want and the RT target you need pull apart, we will tell you which one the pattern is serving.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for wooden slat panels are on the main product page. This page covers what that means for a project in Kolkata.
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.
- MDFStandard. Dry interiors, general commercial
- FR MDFFire rated. Public buildings and anywhere the specification calls for a class
- HDHMRMoisture resistant. Humid climates and rooms that see damp

On a Kolkata job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.
03 / In this market
What we see driving Kolkata briefs
- Tall rooms, hard plaster
High ceilings and lime plaster hold sound for a long time. A room can look magnificent and still defeat anyone trying to speak in it.
- Timber floors between floors
Footfall travels straight down through the joists. A resilient layer under the new finish does more than anything applied to the ceiling below.
- The structure is staying
Conversions here keep the original fabric, so the work has to be internal, shallow and ideally reversible.
- Humid most of the year
PET felt does not hold moisture or feed mould, which matters where mineral products sag within a couple of seasons.
- Assembly and performance rooms
Auditoria, community halls and pandal spaces carry amplified speech and music at high level.
Architects working in Kolkata 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 Kolkata climate decides the material list
Kolkata 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 Kolkata interior where the finish leads, we will say plainly what each option costs you acoustically. See how we work with interior designers.
05 / Logistics
Supply into Kolkata, start to site
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | three days |
| Dispatch | 2 to 4 working days |
| To site | three days |
| Packing | Braced crates, slats supported along their length. Timber moves, so crates are kept flat and dry. |
| Lead time | Longer than felt. Confirmed against the pattern and substrate at quote stage. |
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 fourteen hundred kilometres, normally three days on a dedicated truck.
500 sq ft, about 46 sq m, whatever the substrate, pattern, width or thickness.
| Any specification | 500 sq ft, about 46 sq m |
|---|
One unit covers 96 sq ft, so the minimum is a little over five units. Substrate, slat pattern, width and thickness can be mixed inside the same order.
06 / Before you buy
The things worth knowing before you place the order
-
The wrong product for the problem
A tight slat pattern looks denser but absorbs less, because the open area is what lets sound reach the backing. If the visual you want and the RT target you need pull apart, we will tell you which one the pattern is serving.
-
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 Kolkata
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.
Kolkata: questions we are actually asked
Where are the wooden slat acoustic panels you supply to Kolkata actually made?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Kolkata as the manufacturer rather than through a dealer. Kolkata has the oldest building stock we work with regularly. You buy at factory prices with one consistent batch across the order.
Why would a Kolkata build-up differ from anywhere else?
High ceilings and lime plaster hold sound for a long time. A room can look magnificent and still defeat anyone trying to speak in it. Footfall travels straight down through the joists. A resilient layer under the new finish does more than anything applied to the ceiling below. Those two things move the build-up far more than the panel figure does.
Is this the right material for Kolkata conditions?
Kolkata 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 Kolkata?
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.
Where do wooden slat acoustic panels fail to help?
A tight slat pattern looks denser but absorbs less, because the open area is what lets sound reach the backing. If the visual you want and the RT target you need pull apart, we will tell you which one the pattern is serving.
What quantity do we have to order, and in what packaging?
500 sq ft, about 46 sq m, whatever the substrate, pattern, width or thickness. Any specification, 500 sq ft, about 46 sq m. One unit covers 96 sq ft, so the minimum is a little over five units. Substrate, slat pattern, width and thickness can be mixed inside the same order. Braced crates, slats supported along their length. Timber moves, so crates are kept flat and dry.
