Sliding Door 4 panels on 2 tracks WE 70

The WE 70 4-panel 2-track sliding door is a premium sliding door line from TOSTEM, developed according to strict engineering standards to meet requirements for durability, stability, and operational performance under various conditions. Belonging to the accessible segment, the product still maintains consistent quality and can be easily implemented across many building types.

Frame structure and technical specifications

The door frame has a depth of 72 mm, providing the necessary rigidity for the entire structure. In the three-track configuration, the 104 mm frame enhances load-bearing capacity and operational stability. The bottom sill is 35 mm high, engineered to improve waterproofing performance while ensuring ease of movement. The installed glass thickness options include 5 mm, 6 mm, or 8 mm, matching safety, sound insulation, and thermal insulation requirements.

Drainage and waterproof system

The bottom sill integrates a specialized drainage component that quickly channels rainwater outward. This structure helps minimize water pooling and keeps the interior floor surface dry even under heavy rain conditions.

Convenient handle and security lock

The handle is sturdily designed, providing a comfortable feel during opening and closing operations. A high-quality security lock is equipped as standard, raising the overall protection level for the entire door system.

Flexible keeper adjustment mechanism

The outer panel’s locking keeper can be precisely adjusted, helping maintain airtightness and reducing energy loss. This ensures the door system remains stable, operates smoothly, and extends its overall service life.

Optimized connection with fixed glass panels

The technical configuration allows the door to connect directly with fixed glass panels without requiring an additional transom profile. This design creates a continuous surface, allowing interior spaces to maximize natural light and open up expansive views.

Sliding insect screen

A sliding insect screen is positioned internally, offering flexible operation that provides ventilation while preventing insect intrusion. This feature creates a fresh living environment suitable for modern residential spaces.

International standard performance

The WE 70 4-panel 2-track sliding door has been certified according to JIS standards. Its wind pressure resistance reaches JIS S-1 (800 Pa), water tightness JIS W-2 (150 Pa), air tightness JIS A-3, and sound insulation JIS (25 dB). These parameters demonstrate the product’s stability and effectiveness when installed in projects with demanding technical requirements.
