Safetyline’s integrated internal security bars deliver high airflow and tamper resistance—without airflow loss typical of retrofit screens.
Integrated Design: Permanent internal bars embedded in the frame provide forced-entry deterrence and fall prevention. Locking restrictors (≤125mm opening) comply with NCC requirements while maintaining unobstructed egress.
Maximum Airflow: 235mm glass blade options and wide spans (up to 1200mm) maximize free-area opening. Integrated bars maintain 90%+ free-area ventilation vs. <75% with retrofit screens (15–25% airflow loss).
Night Purging: After-hours passive cooling enabled because security bars remain in place. Manual operation supports demand-controlled ventilation without automation risk.
