Sliding Door 3 panels on 3 tracks WE 70

The WE 70 3-track 3-panel sliding door is a premium sliding door system from TOSTEM, manufactured under strict technical standards to meet the rigorous demands of modern construction. The product achieves a harmonious balance between mechanical performance, aesthetics, and convenience, delivering a sustainable solution at a reasonable investment cost.

Standard technical specifications 

The 3-track sliding door features a frame depth of 104 mm. The bottom frame height is designed at 35 mm, providing sturdiness and stability. Glass thickness options are flexible, available in 5 mm, 6 mm, and 8 mm to suit diverse project requirements.

Frame system and protection capabilities

The bottom frame features an integrated specialized drainage system that efficiently channels water away and prevents rainwater from infiltrating interior spaces. Thanks to this construction, the door maintains airtightness while ensuring long-lasting durability in tropical monsoon climate conditions.

Handle mechanism and safety lock

The door handle is ergonomically optimized to provide a firm grip and effortless operation. Paired with a high-safety lock made from premium materials, it offers exceptional operational durability and effective anti-prying protection, ensuring absolute security for the building.

Latch mechanism and adjustability

The outer sash is equipped with a flexible adjustable latch, allowing users to easily adjust the gap between the frame and sash during installation or maintenance. As a result, the door consistently maintains optimal sealing, minimizes rattling, and reduces energy loss to a minimum.

Intergration with fixed sashes

The WE 70 3-track 3-panel sliding door can be directly combined with fixed glass sashes without requiring additional horizontal mullions. This creates a seamless design, maximizes the view, and optimizes natural daylighting to deliver an open, modern living space.

Sliding insect screen system

The door system comes equipped with a sliding insect screen neatly installed inside the frame. The screen effectively prevents insects from entering while maintaining natural air circulation for interior spaces.

Standard tested performance

According to JIS standards, the WE 70 3-track 3-panel sliding door achieves wind pressure resistance at S-1 (800 Pa), watertightness at W-2 (150 Pa), and airtightness at A-3. Additionally, sound insulation is rated at 25 dB, satisfying requirements for quietness, comfort, and safety. These parameters confirm that the WE 70 system delivers both technical quality and cost efficiency for a wide range of residential and commercial projects.
