Sound isolation
Keep sound where it belongs.
Walls, floors, ceilings, doors and ventilation designed to keep sound in — and out.
The problem
Sound takes the weakest path.
Low-frequency sound travels through building structure as well as through the air. A well-built wall can be undone by a door gap, an air-conditioning duct or a shared floor slab.
Acoustic foam and fabric panels do not stop sound passing through a wall. Isolation depends on how the construction is built: mass, decoupling, damping, airtightness and attention to every path around it.
How we approach it
A method, not a product list.
What you receive
- Isolation targets
- Construction section drawings
- Door and ventilation details
- Material specification
- Site inspection checklist
- Post-build verification
- 01
Identify the paths
Survey the structure, the neighbouring rooms and the noise that needs to be kept in or out.
- 02
Set isolation targets
Decide how much reduction the room needs, based on its use and what is next to it.
- 03
Design the construction
Mass, decoupling, damping and cavity absorption, drawn as section details for the builder.
- 04
Detail the weak points
Doors, ventilation, services and flanking paths through floors and ceilings.
- 05
Inspect during the build
Site checks before linings are closed, when mistakes can still be corrected.
- 06
Verify
Measure the finished construction where the project calls for it.
- MassHeavier layers block more sound
- DecouplingBreak the solid path between surfaces
- DampingTurn vibration into heat
- AbsorptionFill cavities to stop resonance
- Flanking pathsSound that goes around the wall

Questions
Common questions
Will acoustic foam soundproof my room?
No. Foam and fabric panels absorb sound inside a room but block very little from passing through walls. Isolation needs mass, decoupling, damping and airtight construction.
Is bass harder to isolate?
Yes. Low frequencies carry more energy and pass more easily through lightweight construction and building structure. Rooms with subwoofers usually need decoupled construction, not just heavier walls.
How does a sealed room get fresh air?
Through ventilation designed not to carry sound. Ducts are a common weak point, so they are lined, routed and fitted with silencers to keep air moving without letting noise through.
