E3T Sliding window
Boundary-Free Visual Design
• Ultra-Narrow Frame: Merely 3.3cm sash width with embedded profiles that vanish when closed, creating seamless glass expanses.
• Maximized Glass Area: Single panel up to 3.5㎡, with customizable 2- or 3-track configurations (with optional screens).
Silent Smoothness & Durability
• Custom Silent Pulleys: Noise-free operation for undisturbed relaxation.
• German-Engineered Hardware: Collaboration with HOPPE and G-U ensures 100,000+ open/close cycles.
Thermal & Acoustic Insulation
• Precision Thermal Break: Multi-chamber profiles with PA66 nylon barriers minimize heat transfer (U-value ≤1.8 W/m²K), cutting energy loss by 40%.
• Acoustic Engineering: Double-glazed units (5mm glass + 27A argon gap + 5mm glass) reduce noise by ≤35dB.
Typhoon-Grade Security
• Anti-Drop System:
Dedicated Anti-Typhoon Rollers prevent sway/displacement.
Patent Drop-Proof Structure with reinforced outdoor-side heighteners.
• Auto-Hidden Locks: Invisible multi-point locking engages upon closure for intrusion resistance.
