Office acoustics and soundproofing in Switzerland
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. Mechanical ventilation with heat recovery is standard, so duct and terminal unit noise are the sources.
- 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.
- Quote
- From a plan and a section, within 48 hours
01 / What it is
The product, described honestly, for a Switzerland 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.
Mechanical ventilation with heat recovery is standard, so duct and terminal unit noise are the sources.
Work reaching us from Switzerland is mostly apartments, offices, alpine hotels, schools, clinics, studios, timber buildings.
- Timber construction at scale Switzerland builds a lot in timber, and timber is light. Low frequency passes easily, so mass and decoupling do the work, not more absorption.
- Landlocked, so plan the inland leg Rotterdam or Antwerp, then rail. We quote the sea leg and the inland leg separately so the programme runs on real dates.
- The tolerance is zero If the sheet does not perform, you will find out and so will we. That is why we quote what the material does rather than what would win the order.
- 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 Switzerland.

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 Switzerland, mechanical ventilation with heat recovery is standard, so duct and terminal unit noise are the sources.
Direct to wall. Panel bonded or mechanically fixed flat to the substrate. Simplest, and the weakest at low frequency.
-
Layer 2
Acoustic carpet and rugs
A tile carpet with a dense polyester face on a felt backing. In Switzerland, concert halls, church buildings and civic rooms are long-decay volumes where interventions must be reversible.
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 Switzerland, school buildings are built to a high standard with hard cleanable surfaces, so rooms stay live and intelligibility is the target.
Wall array. Panels placed at first reflection points rather than spread evenly. Fewer panels, better result.
We would rather argue about the build-up at design stage than on site. See how we support architects.
03 / Local conditions
What the buildings in Switzerland do to the specification
- Timber construction at scale
Switzerland builds a lot in timber, and timber is light. Low frequency passes easily, so mass and decoupling do the work, not more absorption.
- Landlocked, so plan the inland leg
Rotterdam or Antwerp, then rail. We quote the sea leg and the inland leg separately so the programme runs on real dates.
- The tolerance is zero
If the sheet does not perform, you will find out and so will we. That is why we quote what the material does rather than what would win the order.
- Floor area is extremely expensive
Every centimetre a wall grows into the room is paid for. A dense membrane with a resilient break usually beats a thick framed build-up on both depth and cost.
- Plant and HVAC
Mechanical ventilation with heat recovery is standard, so duct and terminal unit noise are the sources.
04 / Room by room
What each space in a Switzerland project needs
-
Open plan
Distraction distance, not reverberation time. Ceiling absorption plus screens at the desk. Switzerland builds a lot in timber, and timber is light. Low frequency passes easily, so mass and decoupling do the work, not more absorption.
- Ceiling baffles and clouds, 100% PET non-woven, the panel family
- PET felt acoustic panels, 9, 12, 18 and 24 mm standard, tolerance plus or minus 5 percent
- 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. Rotterdam or Antwerp, then rail. We quote the sea leg and the inland leg separately so the programme runs on real dates.
- Ceiling baffles and clouds, 9 to 24 mm
- PET felt acoustic panels, 4 to 24 mm
- Acoustic panels, ASTM C423
-
Cabins and calls
Short RT so a call sounds clean. A small amount of well placed absorber. If the sheet does not perform, you will find out and so will we. That is why we quote what the material does rather than what would win the order.
- Ceiling baffles and clouds, Made to the drawing, standard and custom
- PET felt acoustic panels, 1220 x 2440 mm standard, 4 x 8 ft
- Acoustic panels, 9 to 24 mm, 1220 x 2440 mm standard, up to 2440 x 4270 mm, 1200 to 3600 GSM
For a Switzerland interior where the finish leads, we will say plainly what each option costs you acoustically. See how we work with interior designers.
04 / Climate and durability
The Switzerland climate decides the material list
Switzerland is cool and damp, with long heating seasons and cold external walls, and that narrows the material list before acoustics is discussed.
Cold wall build-ups and long heating seasons mean interstitial condensation is a real risk behind any lining. PET felt is unaffected by damp air and will not feed mould where a fabric-faced mineral product would.
The failure we design against here is condensation behind linings in older, poorly insulated stock.
Where a consultant is already engaged on a Switzerland project, we supply to their specification and send the test reports rather than describing them. More on working with acoustic consultants.
06 / Worth knowing
Where this kind of project usually fails
-
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
Privacy is a transmission problem. Absorption makes the room sound nicer and does not stop anyone hearing through the wall.
-
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 Switzerland job
Switzerland builds a lot in timber, and timber is light. Low frequency passes easily, so mass and decoupling do the work, not more absorption.
05 / Getting it there
What the route into Switzerland actually looks like
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Rotterdam or Antwerp, then rail and road inland |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Rotterdam, then rail |
| Support | Drawings, build-ups, BOQ and material that arrives complete |
Standard items dispatch in 4 to 7 working days. Grooved panels and custom colours take longer, and we say so before you order, not after.
Sea freight into Rotterdam or Antwerp, then rail and road inland. Air freight for samples and urgent quantities.
Questions from Switzerland projects
What makes office acoustics and soundproofing different in Switzerland?
Mechanical ventilation with heat recovery is standard, so duct and terminal unit noise are the sources. If the sheet does not perform, you will find out and so will we. That is why we quote what the material does rather than what would win the order.
Where should the budget go first on a Switzerland 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 Switzerland?
No. We manufacture in India and supply into Switzerland. 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 Switzerland site?
ships from: Palwal, Haryana, India, arrives at: Rotterdam or Antwerp, then rail and road inland, dispatch: 4 to 7 working days. Standard items dispatch in 4 to 7 working days. 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.
