Sliding Door 2 panels on 2 tracks WE 70

The WE 70 2-panel 2-track sliding door is TOSTEM’s optimal solution for modern construction, combining aesthetic appeal, mechanical durability, and stable operation. Designed to comply with JIS international testing standards, this door system ensures long-term performance across various environmental conditions.

Standard Technical Specifications

The door frame depth is 72 mm, whereas the 3-track sliding door version has a frame depth of 104 mm. The bottom frame rail height is 35 mm, providing structural stability and firmness. Glass thickness options are flexible, with choices of 5 mm, 6 mm, and 8 mm to suit diverse project requirements.

Frame System and Water Infiltration Resistance

The bottom frame rail features a dedicated drainage system, efficiently channeling rainwater away and preventing water infiltration into the interior space. Thanks to this design, the door maintains airtightness and guarantees long-term durability in tropical monsoon climates.

Handle Design and Safety Lock

The door handle is ergonomically optimized to offer a comfortable, firm grip and smooth operation. Paired with a high-grade safety lock system, it provides superior operational durability and effective anti-prying protection, ensuring maximum security for the building.

Latch Mechanism and Adjustability

The outer panel is equipped with an adjustable latch mechanism, allowing installers or maintenance personnel to easily fine-tune the gap between the frame and the panel. Consequently, the door consistently maintains optimal tightness, minimizes rattling, and drastically reduces energy loss.

Integration with Fixed Windows

The WE 70 2-panel 2-track sliding door can be combined directly with a fixed glass panel without requiring an additional transom or mullion bar. This creates a seamless appearance, expands the field of view, and maximizes natural light intake for a bright, modern living space.

Sliding Insect Screen

The system is fitted with an integrated sliding insect screen neatly mounted inside the frame. The screen effectively blocks insects while allowing natural air circulation throughout the room.

JIS-Certified Technical Performance

According to JIS standards, the WE 70 2-panel 2-track sliding door offers wind pressure resistance at the S-1 level (800 Pa), water-tightness at W-2 (150 Pa), and air-tightness at A-3. Additionally, its acoustic insulation is tested at 25 dB, fulfilling requirements for quietness, comfort, and safety. These technical parameters confirm that the WE 70 door system delivers verified technical quality at a reasonable cost for residential and commercial applications.
