Office acoustics and soundproofing in Lisbon
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. Split units with condensers in courtyards and light wells, plus seasonal heating in cold damp winters.
- 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 Lisbon
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.
Split units with condensers in courtyards and light wells, plus seasonal heating in cold damp winters.
Work reaching us from Lisbon is mostly hotel and short let conversions, apartments, restaurants, offices, clinics, studios.
- Conversions put beds either side of old walls A house divided into guest rooms turns internal partitions into separating walls overnight. Doors and corridors generate more complaints than the walls themselves.
- Timber floors, every floor Footfall from above is the single most common complaint we hear from this city. It is a floor problem, and treating the ceiling below rarely fixes it.
- Hills and narrow streets Access decides the delivery. Tell us the street and the stairwell and we break pallets down to what will actually get to the room.
- 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 Lisbon.

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 Lisbon, split units with condensers in courtyards and light wells, plus seasonal heating in cold damp winters.
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 Lisbon, church buildings, civic auditoria and function rooms are stone volumes with very long decay.
Zoned. Carpet in the circulation and meeting zones, hard floor elsewhere, so the treatment sits where the noise is made.
-
Layer 3
SoundBlanket mass loaded vinyl
A limp, high density sheet that adds mass to a partition, floor or duct without adding depth. In Lisbon, school buildings are hard surfaced with high ceilings, and canteens are the loudest rooms.
Duct and plant wrap. Membrane wrapped over the duct with a decoupling layer beneath, sealed at every lap.
If you are specifying for a Lisbon 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 Lisbon
- Conversions put beds either side of old walls
A house divided into guest rooms turns internal partitions into separating walls overnight. Doors and corridors generate more complaints than the walls themselves.
- Timber floors, every floor
Footfall from above is the single most common complaint we hear from this city. It is a floor problem, and treating the ceiling below rarely fixes it.
- Hills and narrow streets
Access decides the delivery. Tell us the street and the stairwell and we break pallets down to what will actually get to the room.
- Late districts under homes
Venues in the old districts operate directly beneath apartments. Low frequency containment is what keeps the operation trading.
- Plant and HVAC
Split units with condensers in courtyards and light wells, plus seasonal heating in cold damp winters.

Open plan
Distraction distance, not reverberation time. Ceiling absorption plus screens at the desk. A house divided into guest rooms turns internal partitions into separating walls overnight. Doors and corridors generate more complaints than the walls themselves.
- 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
- SoundBlanket mass loaded vinyl, STC 34, 8.4 kg per sq m
-
Meeting rooms
Privacy between rooms. That is partition and door work, not panels. Footfall from above is the single most common complaint we hear from this city. It is a floor problem, and treating the ceiling below rarely fixes it.
- Ceiling baffles and clouds, 9 to 24 mm
- PET felt acoustic panels, 4 to 24 mm
- SoundBlanket mass loaded vinyl, 12.6 kg per sq m, STC on request
-
Cabins and calls
Short RT so a call sounds clean. A small amount of well placed absorber. Access decides the delivery. Tell us the street and the stairwell and we break pallets down to what will actually get to the room.
- Ceiling baffles and clouds, Made to the drawing, standard and custom
- PET felt acoustic panels, 1220 x 2440 mm standard, 4 x 8 ft
- SoundBlanket mass loaded vinyl, 5 x 1.2 m, 6 sq m per roll
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 Lisbon changes the material, not the target
Lisbon is hot dry summers and mild wet winters, and that narrows the material list before acoustics is discussed.
The swing between a dry summer and a wet winter moves timber. PET felt is dimensionally stable across that swing; slat panels want a stable substrate and a ventilated fixing.
The failure we design against here is seasonal movement in timber and winter damp in unheated stock.
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 / Straight talk
Where this kind of project usually fails
-
Lining every wall while leaving the ceiling bare
A treated wall under a bare hard ceiling gives you a fraction of the reduction you paid for, and the room still sounds wrong.
-
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 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 Lisbon job
A house divided into guest rooms turns internal partitions into separating walls overnight. Doors and corridors generate more complaints than the walls themselves.
05 / Supply
How material reaches a Lisbon site
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Lisbon or Sines, then a short road run to site |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Lisbon or Sines |
| 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 Lisbon or Sines, then a short road run to site. Air freight for samples and urgent quantities.
Questions from Lisbon projects
What makes office acoustics and soundproofing different in Lisbon?
Split units with condensers in courtyards and light wells, plus seasonal heating in cold damp winters. A house divided into guest rooms turns internal partitions into separating walls overnight. Doors and corridors generate more complaints than the walls themselves.
Where should the budget go first on a Lisbon 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 Lisbon?
No. We manufacture in India and supply into Lisbon. 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 Lisbon site?
ships from: Palwal, Haryana, India, arrives at: Lisbon or Sines, then a short road run to site, 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.
Next step
Tell us the room, we will tell you the build-up
Send what you have. We will give you a layer by layer build-up, a bill of quantities and a date material lands, and we will flag anything in the brief that will not achieve what you want.
