What Is A Sliding Window?
Sliding windows move horizontally along built-in tracks to open and close. The DERCHI 80Z model uses precision-engineered aluminum frames with thermal break technology. This construction method places an insulating barrier between the interior and exterior aluminum sections, reducing energy loss through the frame.
The 80Z Sliding Windows feature double glazed glass panels for enhanced thermal and acoustic performance. These custom sliding windows fit various architectural styles and opening sizes. The smooth-gliding operation and secure multi-point locking system make them practical for daily use in homes and commercial buildings.

Performance Specifications
The DERCHI 80Z Sliding Windows combine advanced engineering with practical design. These Custom Sliding Windows feature thermal break aluminum frames and double glazing technology. The system meets strict performance standards for water resistance, air sealing, wind load capacity, sound reduction, and thermal efficiency. Each Double Glazed Sliding Windows unit undergoes rigorous testing to ensure consistent quality. These Thermal Break Aluminum Sliding Windows deliver reliable performance in various climate conditions.
Thermal Insulation - Grade 5 (2.5 W/(㎡·K))
Heat transfer coefficient measures 2.5 watts per square meter kelvin. This rating indicates strong energy efficiency performance. The thermal break aluminum profile interrupts heat flow. Insulated glass units with low-E coatings minimize temperature exchange between interior and exterior environments.
Wind Pressure Resistance - Grade 8 (4.5 kPa)
The structure withstands 4.5 kilopascal wind loads without permanent deformation. This capacity protects against extreme weather events. Reinforced corner joints distribute stress evenly. The frame maintains stability during hurricane-force winds up to 240 km/h.
Water Tightness - Grade 3 (300 Pa)
The window system prevents water infiltration at 300 Pascal pressure. This equals protection against driving rain with wind speeds up to 70 km/h. Specialized drainage channels direct water away from the frame. Multiple sealing points create barriers against moisture penetration.
Air Tightness - Grade 6 (4.5 m³/(m·h))
Air leakage remains below 4.5 cubic meters per hour per meter of joint length. This rating represents superior sealing performance. The multi-chambered frame design reduces air movement. High-quality weather stripping maintains consistent contact between moving parts.
Sound Insulation - Grade 3 (30 dB)
The window system reduces external noise by 30 decibels. This cuts perceived sound levels by approximately 75%. Double glazing with varied glass thickness disrupts sound waves. Acoustic seals between frame components block noise transmission paths.
