FEEPOP Fibre Cement Board Acoustic Wall System
Achieving Up to STC 60 Sound Insulation Performance
In modern building design, acoustic performance has become a key indicator of spatial quality. Hospitals, schools, hotels, offices, and cultural facilities all require effective sound insulation to ensure comfort, privacy, and functionality.
The FEEPOP fibre cement board acoustic wall system, developed through material science and building acoustics principles, delivers reliable sound insulation performance up to STC 60, making it a proven solution for high-performance architectural projects.
Multi-Layer Composite Structure: System-Based Soundproofing
High acoustic performance cannot be achieved by material alone. It requires a well-designed wall system.
The FEEPOP acoustic wall adopts a multi-layer double-leaf structure, combining mass, damping, and structural decoupling to maximize sound reduction.
For example, a 172 mm thick wall system consists of:
-- Three layers of 12 mm FEEPOP fibre cement board on each side, forming high surface mass
-- A 100 mm cavity filled with high-density acoustic insulation to absorb sound energy
-- Light steel framing to achieve structural decoupling
-- Perimeter elastic sealing and staggered joints to eliminate sound bridges
This configuration effectively controls resonance and provides broadband sound insulation.
Proven Acoustic Performance: STC 57–60
Laboratory testing and acoustic modeling demonstrate that:
-- A 148 mm system achieves STC 57
-- An optimized 172 mm system reaches STC 60
The sound insulation curve remains stable across the 125–4000 Hz frequency range, which is critical for speech and environmental noise.
The system also delivers improved low-frequency insulation in the 63–125 Hz range, making it suitable for traffic noise and mechanical equipment sound control.
Typical Building Applications
The FEEPOP fibre cement board acoustic system is ideal for:
-- Healthcare buildings: consultation rooms, wards, functional areas
-- Educational facilities: classrooms, music rooms, lecture halls
-- Hotels: guestroom partition walls, suites
-- Office buildings: meeting rooms, acoustic zoning
-- Cultural buildings: cinemas, theaters, recording spaces
By combining high-density fibre cement boards with a multi-layer composite wall design, the FEEPOP acoustic system delivers predictable, tested, and repeatable sound insulation performance.
With STC ratings from 57 to 60, it provides architects, acoustic consultants, and project owners with a reliable solution for high-standard acoustic wall construction.
As demand for healthier and more comfortable buildings continues to grow, FEEPOP fibre cement board acoustic systems offer a durable and effective approach to modern soundproofing design.
