Product Details
The E5T is a thermal break panoramic sliding window built with 6063-T5 aluminum profiles and PA66 thermal break components. Its embedded sash design hides part of the frame-sash structure in the track, making interior and exterior facades flatter and increasing visible glass area. Operation uses a side-mounted concealed automatic lock hidden on the sash side that engages when the sash is pushed to the closed position, combined with a double-row pulley design that increases contact and support with the track. A high-low track creates stepped drainage with an outer water baffle and anti-fall structure, while diversion chambers and seals at track ends, the bottom frame, and fixed glass positions reduce rainwater entry. Two-track frame width is approximately 93 mm and three-track frame width is approximately 131 mm.
Standard glass is 5 mm + 12A + 5 mm double tempered insulating glass with a PVDF spacer bar and inert gas fill, and optional glass types include Low-E, laminated, triple glazing, frosted, tinted, reflective, or ultra-clear glass. Sash glass can be fixed by gluing on the inner or outer side, and fixed glass uses rubber strip installation. The active sash engineering range is width 500-2000 mm and height 500-1400 mm, with a maximum single fixed glass area of approximately 3.5 m². Combinations wider than approximately 2500 mm can be configured with a Type A reinforced handle, and combinations wider than approximately 3000 mm can use a Type B reinforced handle. A three-track structure allows the screen sash and glass sash to move independently. Buyers should confirm track count, glass type, sash dimensions, and handle reinforcement level before finalizing the configuration.
Product Features
Model E5T is a thermal break panoramic sliding window emphasizing large glass — select this model for openings requiring unobstructed glass views with thermal break construction.
Profile material is 6063-T5 thermal break aluminum with 1.8 mm main wall thickness — choose this alloy and wall thickness when specifying thermal break aluminum frames.
Two-track frame width is approximately 93 mm and three-track is approximately 131 mm — select track count based on available wall depth and whether independent screen sash operation is needed.
Three-track structure allows screen sash and glass sash to move independently — choose three-track when separate screen and glass operation is required.
Active sash engineering range spans width 500–2000 mm and height 500–1400 mm — confirm opening dimensions fall within this range before specifying sash size.
Configurations include two-sash, three-sash, four-sash, six-sash, top light, bottom fixed, horizontal long window, left-right asymmetric, and multi-grid combinations — match sash layout to facade composition.
Optional add-ons include openable guardrail, clothes drying rack, anti-theft block, key lock, and child limiter — specify accessories based on safety and daily-usage requirements.
Facade options include horizontal long window, rectangular window wall, upper arched fixed area, bottom fixed, and multi-bay combinations — choose facade type to match architectural style.
Glazing is double tempered insulating glass (5 mm + 12A + 5 mm) with inert gas fill — select this glazing assembly for thermal and acoustic performance.
Finish options include powder coating, PVDF coating, wood grain, and dual-color — choose finish by exterior and interior color scheme.
