Office acoustics and soundproofing in Chicago
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. Packaged rooftop units and ducted forced air are standard, so noise arrives through the duct rather than through the wall. Lining the first three metres of duct and treating the return path is usually the whole job.
- 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 / What it is
The product, described honestly, for a Chicago brief
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.
Packaged rooftop units and ducted forced air are standard, so noise arrives through the duct rather than through the wall. Lining the first three metres of duct and treating the return path is usually the whole job.
Work reaching us from Chicago is mostly two-flats and three-flats, high-rise apartments, offices, venues, schools, clinics.
- Elevated rail past the window Trains at window height put noise in through the glazing, not through the wall. The facade is where the money should go first.
- No port, so plan the inland leg Everything arrives at a coast and rails in. We quote the sea leg and the inland leg separately.
- Brick outside, timber inside Two-flats and three-flats have solid masonry outside and timber floors between families. Footfall travels down and masonry does nothing about it.
- 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 Chicago.

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 Chicago, packaged rooftop units and ducted forced air are standard, so noise arrives through the duct rather than through the wall. Lining the first three metres of duct and treating the return path is usually the whole job.
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 Chicago, churches, school gyms and multipurpose halls double as performance spaces, which means a room designed for neither speech nor music has to carry both.
Direct to wall. Panel bonded or mechanically fixed flat to the substrate. Simplest, and the weakest at low frequency.
-
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 Chicago, public school buildings run long corridors with hard floors and lay-in tile ceilings that were chosen for cost, not for speech. Classroom reverberation and corridor spill are the two complaints, and both respond to ceiling area rather than wall panels.
Ceiling first. In most rooms the ceiling is the largest untreated surface and the cheapest square metre of result.
If you are specifying for a Chicago project, we can give you a section, a BOQ and the honest limits of each layer. See how we support architects.
03 / On the ground
What the buildings in Chicago do to the specification
- Elevated rail past the window
Trains at window height put noise in through the glazing, not through the wall. The facade is where the money should go first.
- No port, so plan the inland leg
Everything arrives at a coast and rails in. We quote the sea leg and the inland leg separately.
- Brick outside, timber inside
Two-flats and three-flats have solid masonry outside and timber floors between families. Footfall travels down and masonry does nothing about it.
- Sealed against hard winters
Buildings close up for months and mechanical systems run hard, so sound accumulates inside rather than escaping.
- Plant and HVAC
Packaged rooftop units and ducted forced air are standard, so noise arrives through the duct rather than through the wall. Lining the first three metres of duct and treating the return path is usually the whole job.
04 / Room by room
What each space in a Chicago project needs
-
Open plan
Distraction distance, not reverberation time. Ceiling absorption plus screens at the desk. Trains at window height put noise in through the glazing, not through the wall. The facade is where the money should go first.
- Ceiling baffles and clouds, 100% PET non-woven, the panel family
- Acoustic carpet and rugs, 4 mm
- Acoustic panels, Cut pattern in PET felt, adds visual rhythm without changing the absorber
-
Meeting rooms
Privacy between rooms. That is partition and door work, not panels. Everything arrives at a coast and rails in. We quote the sea leg and the inland leg separately.
- Ceiling baffles and clouds, 9 to 24 mm
- Acoustic carpet and rugs, High density polyester
- Acoustic panels, ASTM C423
-
Cabins and calls
Short RT so a call sounds clean. A small amount of well placed absorber. Two-flats and three-flats have solid masonry outside and timber floors between families. Footfall travels down and masonry does nothing about it.
- Ceiling baffles and clouds, Made to the drawing, standard and custom
- Acoustic carpet and rugs, Felt
- Acoustic panels, 9 to 24 mm, 1220 x 2440 mm standard, up to 2440 x 4270 mm, 1200 to 3600 GSM
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 / Climate
What the Chicago climate rules in and rules out
Chicago is mild summers and cold, wet winters, and that narrows the material list before acoustics is discussed.
Cold external walls and long heating seasons make condensation behind a lining the thing to design out. PET felt is unaffected by damp air.
The failure we design against here is condensation and cold bridging behind new linings.
If a consultant has set the target, we will quote against their figures rather than ours, and stay out of the scope they own. More on 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
If the complaint is being overheard, no amount of absorption inside the room will fix it. That is a partition job and we will say so.
-
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 Chicago job
Trains at window height put noise in through the glazing, not through the wall. The facade is where the money should go first.
05 / Logistics
What the route into Chicago actually looks like
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | An East or Gulf coast port, then rail and road inland |
| Dispatch | 4 to 7 working days |
| Freight | Sea, then rail inland |
| Support | Drawings, build-ups, BOQ and material that arrives complete |
Standard items dispatch in 4 to 7 working days. The sea leg from India is long, so plan the full door to door window into the programme. We give real dates, not optimistic ones.
Sea freight into an East or Gulf coast port, then rail and road to Chicago. Air freight for samples and urgent quantities.
Questions from Chicago projects
What makes office acoustics and soundproofing different in Chicago?
Packaged rooftop units and ducted forced air are standard, so noise arrives through the duct rather than through the wall. Lining the first three metres of duct and treating the return path is usually the whole job. Trains at window height put noise in through the glazing, not through the wall. The facade is where the money should go first.
Where should the budget go first on a Chicago 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 Chicago?
No. We manufacture in India and supply into Chicago. 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 Chicago site?
ships from: Palwal, Haryana, India, arrives at: An East or Gulf coast port, then rail and road inland, dispatch: 4 to 7 working days. Standard items dispatch in 4 to 7 working days. The sea leg from India is long, so plan the full door to door window into the programme. We give real dates, not optimistic ones.
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.
Next step
Drawings in, BOQ and a delivered date out
We quote from drawings, not from a square foot rate. Send a plan and the section through the critical wall or ceiling and you will get something you can actually build from.
