    Non-combustible autoclaved aerated concrete core - it will not burn or feed a fire.

    Tested to AS 1530.4 · AS 5113

    Rw+Ctr≥ 50dB

    Acoustic

    Dense, sound-absorbing panels deliver intertenancy separation without secondary linings.

    Up to R 3.33 system

    Thermal

    High thermal mass holds a steady internal temperature and lifts the whole-of-wall R-value.

    NCC 2025 · Section J

    50+ year design life

    Durability

    Steel-reinforced panels resist rot, warping and termites - a low-maintenance envelope.
