DERCHI WZ-80 Folding Door Overview
The WZ-80 aluminum folding door system features an 80mm frame width built with 6063-T5 aluminum profiles at 2.0mm wall thickness. Designed for commercial procurement and industrial applications, this bi-fold door configuration accommodates large opening spans while maintaining controlled air and water penetration performance.
WZ-80 Folding Door Technical Specifications
Performance Advantages
Structural Wind Load Capacity for Mid-Rise Projects
The 2.0mm 6063-T5 aluminum profile construction achieves 4.5KPa wind pressure resistance, meeting the structural requirements of mid-rise commercial and residential buildings. This rating allows specification in coastal and elevated locations where consistent wind load performance is required for project compliance.
Multi-Layer Sealing System
The BAIYUNYILE insulation strip and perimeter sealing configuration work together to close gaps between folding panels, supporting the published air and water penetration performance figures.
CMECH Hardware Integration
Full CMECH hardware — including handles, hinges and dedicated locking points — provides consistent operational mechanics across repeated folding cycles and uniform locking engagement along the door panel.
Thermal and Acoustic Insulation
With a U-factor of 0.38 and SHGC of 0.22, the insulated glass assembly lowers heat transfer through the building envelope. The 35 dB sound insulation rating helps reduce external noise transmission for occupied interior spaces.
U-Factor (U.S./1-P): 0.38
Wind Pressure Resistance: 4.5 KPa
Water Tightness: 450 Pa
Air Tightness: 1.8 m³/(m·h)
Sound Insulation: 35 dB
CMECH hardware standard across all configurations
Nine standard layouts reduce custom engineering cost
10-year profile warranty lowers long-term maintenance
Multi-country installation service for international buyers
35 dB sound insulation for occupied commercial spaces

WZ-80 Hardware and Accessory Options
The WZ-80 series uses DERCHI developed and customized hardware components designed for consistent operation over repeated cycles.
Integrated Folding Mesh Screen
An optional folding mesh screen is compatible with the WZ-80 system, providing insect protection when the door is partially or fully opened. The mesh retracts in line with the folding panels and does not require separate mounting frames.
CMECH Handle Assembly
The ergonomic lever handle is supplied by CMECH in black or silver finish options. It operates the multi-point locking mechanism and is designed for repeated daily use in commercial entrance and patio applications.
Stainless Steel Pulley System
The bottom track incorporates stainless steel pulley assemblies that carry each folding panel along the horizontal guide rail. This design supports smooth panel travel and reduces operating effort even with larger multi-panel configurations.
Sealing Insulation Strip
Continuous sealing insulation strips run along the full perimeter of each folding panel, maintaining consistent contact between sashes when closed. This contributes to the published air and water tightness ratings of the system.
