Office acoustics and soundproofing in Delhi
Three separate problems get called one problem: speech carrying across an open floor, meeting rooms that leak, and hard rooms that ring. Each has a different answer and mixing them up is how budgets get wasted. Diesel generator sets, split unit banks and VRF outdoor units sit on terraces and in shafts close to bedrooms and offices.
- Open plan
- Distraction distance, not reverberation time. Ceiling absorption plus screens at the desk.
- Meeting rooms
- Privacy between rooms. That is partition and door work, not panels.
- Cabins and calls
- Short RT so a call sounds clean. A small amount of well placed absorber.

01 / The material
What you are buying, and what it fixes in Delhi
Three separate problems get called one problem: speech carrying across an open floor, meeting rooms that leak, and hard rooms that ring. Each has a different answer and mixing them up is how budgets get wasted.
Diesel generator sets, split unit banks and VRF outdoor units sit on terraces and in shafts close to bedrooms and offices.
Work reaching us from Delhi is mostly offices, studios, banquet halls, clinics, schools, home theatres, restaurants, showrooms.
- Old walls and new towers Lutyens bungalows, 1970s DDA flats and glass towers all fail differently. We ask what the wall actually is before quoting anything.
- Same day from the plant Ninety kilometres of road. Low freight cost, next-day samples, and a damaged sheet replaced without a two-week wait.
- We can come and look Delhi is close enough that a site visit is straightforward. On a difficult room that is worth more than any amount of specification over email.
- Open plan Distraction distance, not reverberation time. Ceiling absorption plus screens at the desk.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for office acoustics are on the main product page. This page covers what that means for a project in Delhi.

02 / The build-up
The stack, in the order it is installed
-
Layer 1
Ceiling baffles and clouds
PET felt suspended from the soffit, vertically as baffles or horizontally as clouds. In Delhi, diesel generator sets, split unit banks and VRF outdoor units sit on terraces and in shafts close to bedrooms and offices.
Vertical baffles. Hung on edge in rows. Both faces absorb, so coverage figures based on plan area understate them.
-
Layer 2
PET felt acoustic panels
A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. In Delhi, auditoriums, banquet halls and places of worship are large hard volumes in concrete and stone where speech falls apart long before anyone calls the room echoey.
On a 25 to 50 mm air gap. The same panel on battens. The air gap moves absorption down in frequency at no extra material cost, and is the cheapest improvement available.
-
Layer 3
Acoustic panels
The full absorber range rather than one product: plain PET felt, printed felt, grooved panels and fabric finishes, chosen by how the room is used and how it has to look. In Delhi, classrooms are concrete and tile with bare walls and high ceilings, and class sizes push levels up. Corridors act as reverberation chambers that feed every room off them.
Mixed finish. Plain felt where it is out of eye line, printed or grooved where it is seen.
We would rather argue about the build-up at design stage than on site. See how we support architects.
03 / In this market
The Delhi conditions that change the answer
- Old walls and new towers
Lutyens bungalows, 1970s DDA flats and glass towers all fail differently. We ask what the wall actually is before quoting anything.
- Same day from the plant
Ninety kilometres of road. Low freight cost, next-day samples, and a damaged sheet replaced without a two-week wait.
- We can come and look
Delhi is close enough that a site visit is straightforward. On a difficult room that is worth more than any amount of specification over email.
- Traffic and generators get in
On most Delhi sites the noise arrives through windows, shafts and gaps rather than through the wall itself. Fixing the weakest path first saves money.
- Plant and HVAC
Diesel generator sets, split unit banks and VRF outdoor units sit on terraces and in shafts close to bedrooms and offices.

Interior designers tend to arrive with the look already decided. We will tell you which finish gets there without losing the acoustics. See how we work with interior designers.
04 / Conditions
What the Delhi climate rules in and rules out
Delhi is hot summers, mild winters and a distinct wet season, and that narrows the material list before acoustics is 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 failure we design against here is wet-season humidity behind linings.
On a Delhi job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.
06 / Worth knowing
The six errors that cost the most
-
Lining every wall while leaving the ceiling bare
The ceiling is almost always the largest untreated surface, so leaving it out means paying for panels that cannot reach the target.
-
Treating a privacy problem with absorption
Nobody has ever achieved speech privacy with a panel. Privacy needs mass, a sealed head detail and a door that actually closes.
-
Glass cabins specified without a door and head detail
A gap undoes the partition it sits in. Sealing is the cheapest line on the quote and the first one to get cut.

Treating it as a generic Delhi job

05 / Getting it there
Supply into Delhi, start to site
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | same or next day |
| Dispatch | 2 to 4 working days |
| To site | same or next day |
| Support | Drawings, build-ups, BOQ and material that arrives complete |
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.
Same day or next day by road from Palwal, about ninety kilometres south. Small consignments on a shared vehicle, full loads on a dedicated truck.
Questions from Delhi projects
What makes office acoustics and soundproofing different in Delhi?
Diesel generator sets, split unit banks and VRF outdoor units sit on terraces and in shafts close to bedrooms and offices. Delhi is close enough that a site visit is straightforward. On a difficult room that is worth more than any amount of specification over email.
Where should the budget go first on a Delhi project?
Open plan. Distraction distance, not reverberation time. Ceiling absorption plus screens at the desk. Meeting rooms. Privacy between rooms. That is partition and door work, not panels.
Do you have an office or installation team in Delhi?
No. We manufacture in India and supply into Delhi. We give you drawings, build-ups, a BOQ and material that arrives complete, and we will tell you plainly when a job needs a local contractor we cannot be.
How does material get to a Delhi site?
made at: Our own plant, Palwal, Haryana, reaches site in: same or next day, 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 goes wrong most often on this kind of project?
Lining every wall while leaving the ceiling bare. Treating a privacy problem with absorption.
What do you need from us to quote?
A plan, a section through the critical partition or ceiling, and what the room is for. From that we can give a build-up and a BOQ rather than a price per square foot.
