Home sound insulation

What is home sound insulation?

Home sound insulation is a holistic acoustic-engineering service that evaluates every noise source in a residence together and produces a tailored solution for each. It is not just insulating one wall — it is a 360° design approach covering the whole apartment. This is the most common approach we see in existing homes.

The most frequent noise issues in homes

• Speech / TV from a neighbour (Rw 36-42 → 50+ target)
• Footsteps from upstairs (weak ΔLw → 22+ ΔLw target)
• Street / traffic noise (weak facade Rw + Ctr)
• Insufficient internal-room separation (bedroom — living room)
• Bathroom / kitchen plumbing / pipe noise
• Lift vibration and shaft noise

How does the holistic approach work?

1. Detailed survey: walking the whole flat, mapping problem points.
2. Comprehensive measurement: separate Rw / ΔLw measurements for each wall/ceiling/floor.
3. Prioritisation: the most disturbing source first; maximum impact for a given budget.
4. Modular design: phased application plan (can start on a limited budget).
5. Turnkey delivery: paint, flooring and everything restored to original.
6. Final measurement: separate report for each component.

Target performance (residential comfort level)

• Party wall between flats: Rw 50-55 dB
• Upstairs ceiling: Rw 50+ + ΔLw 25+
• Facade (traffic): DnT,w + Ctr 35+ dB
• Internal-room partition: Rw 42-48 dB
• Acoustic door: Rw 32-38 dB
• Acoustic glass: Rw 38-42 dB

Phased-application approach

For budget-limited customers we recommend: instead of insulating the whole flat at once, the 1-2 most disturbing problems are solved first, then other components are added over time. The multi-layer build is composite, so additions can be retrofitted.

Building components we use

We have separate detail pages per category for each wall/ceiling/floor system.

Lead time, cost and continuing to live in the home

A typical full home insulation runs 2-4 weeks. The family can stay in the home during application; however, due to noise and dust, a 1-2 week hotel stay may be recommended. Dry systems (plasterboard, suspended ceiling) are preferred so demolition is minimal.
