Home theatre soundproofing and acoustics in Portugal
Serious equipment in a room with no isolation plan. The complaint is almost never the speakers. It is bass leaving the room and an untreated box making the system sound worse than it is. Masonry and concrete blocks with tile and stone floors, in buildings that share walls and courtyards.
- Containment
- Bass through the wall, floor and door. Mass and decoupling, with the door usually the weakest point.
- Low frequency inside
- Corner absorption with depth, before any surface treatment.
- Reflections
- Side wall and ceiling first reflection points at the seating position.
- Quote
- From a plan and a section, within 48 hours

What you are buying, and what it fixes in Portugal
Serious equipment in a room with no isolation plan. The complaint is almost never the speakers. It is bass leaving the room and an untreated box making the system sound worse than it is.
Masonry and concrete blocks with tile and stone floors, in buildings that share walls and courtyards.
Work reaching us from Portugal is mostly hotel and apartment conversions, restaurants, offices, clinics, schools, studios.
- Timber floors in old buildings Footfall passes straight down through the joists. A resilient layer under the new finish does more than anything applied to the ceiling below.
- Conversion, not construction The structure is staying. Whatever we propose has to work inside the depth and the finishes that are already there, which rules out most thick framed systems.
- Atlantic damp Our PET felt does not absorb moisture, shed fibre or feed mould, which matters on cold external walls in a mild wet climate where mineral products sag.
- Containment Bass through the wall, floor and door. Mass and decoupling, with the door usually the weakest point.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for home theatre soundproofing are on the main product page. This page covers what that means for a project in Portugal.
02 / The build-up
The stack, in the order it is installed
-
Layer 1
SoundBlanket mass loaded vinyl
A limp, high density sheet that adds mass to a partition, floor or duct without adding depth. In Portugal, split units with condensers in courtyards and light wells, plus seasonal heating in cold damp winters.
Wall, decoupled. Independent stud, membrane between the boards, cavity absorption, two boards. The membrane is one part of a system, never the whole answer.
-
Layer 2
Soundproofing materials
The blocking side of the range taken together: mass loaded vinyl, resilient layers, cavity absorption and the build-ups they belong in. In Portugal, church buildings, civic auditoria and function rooms are stone volumes with very long decay.
Independent leaf. A second wall that does not touch the first. Nothing else comes close for the money.
-
Layer 3
Soundproof curtains
A layered curtain with a mass loaded vinyl core, used where an opening has to stay an opening. In Portugal, school buildings are hard surfaced with high ceilings, and canteens are the loudest rooms.
Track with a seal. Ceiling track plus a floor seal or drape, so the perimeter is closed when it is drawn.
Architects working in Portugal usually need the build-up before the product. We will draw the section and mark what does the work. See how we support architects.
03 / On the ground
What we see driving Portugal briefs
- Timber floors in old buildings
Footfall passes straight down through the joists. A resilient layer under the new finish does more than anything applied to the ceiling below.
- Conversion, not construction
The structure is staying. Whatever we propose has to work inside the depth and the finishes that are already there, which rules out most thick framed systems.
- Atlantic damp
Our PET felt does not absorb moisture, shed fibre or feed mould, which matters on cold external walls in a mild wet climate where mineral products sag.
- Tourism programmes have fixed dates
Hotel openings do not move. We give honest dispatch and transit windows so the fit-out is not waiting on a container.
- The housing stock
Masonry and concrete blocks with tile and stone floors, in buildings that share walls and courtyards.
04 / Room by room
What each space in a Portugal project needs
-
Containment
Bass through the wall, floor and door. Mass and decoupling, with the door usually the weakest point. Footfall passes straight down through the joists. A resilient layer under the new finish does more than anything applied to the ceiling below.
- SoundBlanket mass loaded vinyl, 2100 kg per cubic metre
- Soundproof curtains, 10 to 12 mm
- Acoustic carpet and rugs, High density polyester
-
Low frequency inside
Corner absorption with depth, before any surface treatment. The structure is staying. Whatever we propose has to work inside the depth and the finishes that are already there, which rules out most thick framed systems.
- SoundBlanket mass loaded vinyl, STC 30, 5.25 kg per sq m
- Soundproof curtains, 5.5 kg per sq m
- Acoustic carpet and rugs, Felt
-
Reflections
Side wall and ceiling first reflection points at the seating position. Our PET felt does not absorb moisture, shed fibre or feed mould, which matters on cold external walls in a mild wet climate where mineral products sag.
- SoundBlanket mass loaded vinyl, STC 34, 8.4 kg per sq m
- Soundproof curtains, Up to 30 dB
- Acoustic carpet and rugs, 64 sq ft per pack
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
Why the climate in Portugal changes the material, not the target
Portugal 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 / Worth knowing
Six mistakes that turn into a second fit-out
-
Foam on the walls as a soundproofing measure
Small on the drawing, expensive on site, and almost always found after handover.
-
A standard door on a room built to hold bass
Soundproofing fails at the gaps, not the materials. One unsealed service penetration can undo a correctly built wall.
-
Treating before the room is sealed
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 Portugal job
Footfall passes straight down through the joists. A resilient layer under the new finish does more than anything applied to the ceiling below.
05 / Route to site
Supply into Portugal, start to site
| Ships from | Palwal, Haryana, India |

Questions from Portugal projects
What makes home theatre soundproofing and acoustics different in Portugal?
Masonry and concrete blocks with tile and stone floors, in buildings that share walls and courtyards. The structure is staying. Whatever we propose has to work inside the depth and the finishes that are already there, which rules out most thick framed systems.
Where should the budget go first on a Portugal project?
Containment. Bass through the wall, floor and door. Mass and decoupling, with the door usually the weakest point. Low frequency inside. Corner absorption with depth, before any surface treatment.
Do you have an office or installation team in Portugal?
No. We manufacture in India and supply into Portugal. 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 Portugal site?
ships from: Palwal, Haryana, India, arrives at: Sines, Lisbon or Leixões, then road 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?
Foam on the walls as a soundproofing measure. A standard door on a room built to hold bass.
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.
