135 Series Lift & Slide Doors

The 135 Series heavy lift and slide door is built around a 2.2mm aluminium wall — the heaviest in our range — and a 135mm frame depth that allows oversized glass panels to glide smoothly without racking. Three opening modes are available as standard: manual push, infrared sensor activation, and facial-recognition activation, all driven by Yihuichuang electric hardware. Glazing up to 29-30mm is accommodated within a 30mm multi-chamber thermal break, delivering Uf 1.6–2.0 W/(m²·K) and 32 dB acoustic insulation, with Class 8 wind resistance and Class 4 air and water tightness. Composite brush seals combine with EPDM weather-stripping and a self-expanding screw-corner assembly for long-term stability under heavy use. Suitable for residential penthouses, hospitality and commercial openings where the threshold between inside and out should disappear at the touch of a hand. Send us your opening dimensions and we will confirm the configuration, panel layout and hardware.
