Office acoustics and soundproofing in Seattle
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 / The material
What this material is and where it earns its place in Seattle
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 Seattle is mostly mass timber offices, tech campuses, multifamily, studios, schools, clinics.
- Mass timber is still light Exposed timber looks solid and performs nothing like concrete at low frequency. It also cannot be covered, because the timber is the design, so the acoustic work has to happen where it will not be seen.
- Rain on the roof Metal and membrane roofs over open volumes turn heavy rain into a noise source. It is worth designing for rather than discovering in the first storm.
- Campus open plans Large tech floors with exposed structure and hard finishes carry speech a long way. The ceiling plane and screens have to do what the walls are not there to do.
- 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 Seattle.

02 / The build-up
How the layers stack, from the structure inwards
-
Layer 1
PET felt acoustic panels
A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. In Seattle, 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.
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 2
Acoustic carpet and rugs
A tile carpet with a dense polyester face on a felt backing. In Seattle, churches, school gyms and multipurpose halls double as performance spaces, which means a room designed for neither speech nor music has to carry both.
Zoned. Carpet in the circulation and meeting zones, hard floor elsewhere, so the treatment sits where the noise is made.
-
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 Seattle, 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.
Wall array. Panels placed at first reflection points rather than spread evenly. Fewer panels, better result.
If you are specifying for a Seattle project, we can give you a section, a BOQ and the honest limits of each layer. See how we support architects.
03 / Local conditions
What decides the build-up in Seattle
- Mass timber is still light
Exposed timber looks solid and performs nothing like concrete at low frequency. It also cannot be covered, because the timber is the design, so the acoustic work has to happen where it will not be seen.
- Rain on the roof
Metal and membrane roofs over open volumes turn heavy rain into a noise source. It is worth designing for rather than discovering in the first storm.
- Campus open plans
Large tech floors with exposed structure and hard finishes carry speech a long way. The ceiling plane and screens have to do what the walls are not there to do.
- The port is right here
Containers land at Seattle or Tacoma, so there is no cross-country leg. That keeps the landed cost and the date both predictable.
- 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
Room by room, on a typical Seattle job
-
Open plan
Distraction distance, not reverberation time. Ceiling absorption plus screens at the desk. Exposed timber looks solid and performs nothing like concrete at low frequency. It also cannot be covered, because the timber is the design, so the acoustic work has to happen where it will not be seen.
- PET felt acoustic panels, 100% PET non-woven, no added binder
- 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. Metal and membrane roofs over open volumes turn heavy rain into a noise source. It is worth designing for rather than discovering in the first storm.
- PET felt acoustic panels, 9, 12, 18 and 24 mm standard, tolerance plus or minus 5 percent
- 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. Large tech floors with exposed structure and hard finishes carry speech a long way. The ceiling plane and screens have to do what the walls are not there to do.
- PET felt acoustic panels, 4 to 24 mm
- 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
Designers get colour, pattern and CNC options with the absorption figure attached to each. See how we work with interior designers.
04 / Climate and durability
Why the climate in Seattle changes the material, not the target
Seattle 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.
Consultants get the raw data, not a sales sheet. That is the whole of our side of the job, and it is set out under working with acoustic consultants.
06 / Before you buy
What we watch go wrong on jobs like this
-
Lining every wall while leaving the ceiling bare
Square metre for square metre the ceiling is the cheapest result in the room. Skipping it and buying wall panels instead is the most common way to overspend.
-
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 6 mm undercut under a door leaves a hole the size of a brick. The wall around it is then decorative.
-
Treating it as a generic Seattle job
Exposed timber looks solid and performs nothing like concrete at low frequency. It also cannot be covered, because the timber is the design, so the acoustic work has to happen where it will not be seen.
05 / Supply
What the route into Seattle actually looks like
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Seattle or Tacoma, then a short road run to site |
| Dispatch | 4 to 7 working days |
| Freight | Sea into Seattle or Tacoma |
| 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 Seattle or Tacoma, then a short road run to site. Air freight for samples and urgent quantities.
Questions from Seattle projects
What makes office acoustics and soundproofing different in Seattle?
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. Exposed timber looks solid and performs nothing like concrete at low frequency. It also cannot be covered, because the timber is the design, so the acoustic work has to happen where it will not be seen.
Where should the budget go first on a Seattle 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 Seattle?
No. We manufacture in India and supply into Seattle. 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 Seattle site?
ships from: Palwal, Haryana, India, arrives at: Seattle or Tacoma, then a short road run to site, 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.
