Superior Noise Control

Certified Acoustic Performance: Achieves Rw 46 dB (Personnel Door) and Rw 45 dB (Double Door) – exceptional noise reduction across industrial, commercial, and high-noise environments
Low-Frequency Attenuation: Effectively minimises machine-generated hums and deep industrial noises (28.8 dB at 100 Hz)
Broad Frequency Coverage: Optimised mid-to-high frequency blocking (51.6 dB at 5000 Hz) ensures comprehensive sound control
Double Runner Seals: Unique dual-seal system prevents sound leakage

Easy Installation

SonicFix Ready-to-Fit Design: Australia’s only 100% ready-to-install door set – arrives pre-hung in portal frame with all hardware factory fitted
Fast Install: Minimal on-site assembly required; can be installed by builders or end-users without specialist knowledge
Time & Cost Savings: Reduces installation time and labour costs while guaranteeing acoustic performance
Immediately Operational: Doors are powder-coated and factory-painted, ready for use straight after fitting
Flexible Installation: Compatible with concrete, metal, or timber support structures – no concrete casting required
