Product Details
The frame is extruded from 6063-T5 aluminum alloy with a main wall thickness of 1.4 mm, and sash sections measure approximately 40 mm in thickness with a visible face of approximately 60 mm. Corner joints use a 45-degree splicing process for improved flatness. Sashes run on high-low tracks equipped with custom silent rollers, upper anti-swing rollers, and an anti-drop structure, while the track system uses a high-low differential with concealed external drainage. Overlap areas use siliconized weatherstripping, and fixed glass areas use rubber strips or sealant. Standard glazing is 5 mm + 12A + 5 mm double tempered insulated glass with a black PVDF spacer.
The window is available in two-track or three-track configurations, with structural options including two-sash two-track, three-sash three-track, four-sash two-track, left-right fixed with center opening, top light/bottom fixed, and screen combinations. Procurement teams should confirm finished dimensions, track configuration, glass type, mesh, color, lock, roller grade, wrapping, and fixed area before ordering. Glass options include double or triple insulated, Low-E, laminated, reflective, tinted, tempered, and high-security glass, and fixed glass can be installed from either the interior or exterior side.
Product Features
Model 80Z is a general-purpose aluminum alloy sliding window for residential renovation, apartments, kitchens, bedrooms, living rooms, and balconies.
Two-track or three-track configuration determines sash count and whether an independent 304 stainless steel mesh sash can be integrated.
Active sash width range of 350–1400 mm and height range of 500–2700 mm sets the feasible opening dimensions per project.
Structural options include two-sash two-track, three-sash three-track, four-sash two-track, left-right fixed with center opening, top light/bottom fixed, and screen combinations, defining the window layout pattern.
The system does not use vertical curved bending; shaped facades are achieved through linear division, top lights, bottom fixed panels, or multi-window combinations.
Standard mesh uses 304 stainless steel at approximately 0.8 mm wire diameter and 11 mesh; alternative high-transparency or denser insect screen is available.
Lock options include HOPO/HOPPE type embedded handles, automatic sliding locks, and an optional keyed flush lock, affecting protrusion and security level.
The current export configuration uses a thermal break profile.

Color options: Sand Grey, Dark Coffee, Light Coffee, White, Indigo, Soft Gold, Marble Black, Black Walnut, Pear Wood, Black Spinel, Galaxy.
Surface finishes: powder coating, fluorocarbon, wood grain, and indoor-outdoor dual color; dual color is a custom surface process.
Optional 10×18 decorative grilles are available.
Active sash width range: 350–1400 mm; active sash height range: 500–2700 mm.
Roller load capacity options: approximately 30 kg, 50 kg, or higher.
Wrapping options: approximately 47, 70, 75, 100 mm; European standard 80/110 mm.
Hardware Accessories
Sashes run on high-low tracks with custom silent rollers, upper anti-swing rollers, and an anti-drop structure.
HOPO/HOPPE type embedded handles or automatic sliding locks reduce protrusion.
Optional keyed flush lock is available.
Roller components can be configured for approximately 30 kg, 50 kg, or higher load capacity depending on sash weight.
Track uses high-low differential and concealed external drainage.
Exterior can be configured with waterproof blocks and drainage covers to reduce storm backflow.
Three-track version can be configured with an independent 304 stainless steel mesh sash; two-track version can also have mesh solutions per project.
Basic Parameters
Performance Dimension | Meaning | Product Configuration | Test Evidence to Request |
|---|---|---|---|
Thermal Insulation | Resistance to conductive heat transfer through the frame and glazing assembly, typically rated by U-factor. | Thermal break profile in the current export configuration. | NFRC simulation report or label listing U-factor for the configured frame and glass. |
Wind Pressure Resistance | Capacity of the window assembly to withstand design wind loads without structural failure or permanent deflection. | Confirm the required rating class for the target project's design wind load. | AS2047 structural test report for the specified window size and glazing configuration. |
Water Tightness | Resistance to water penetration under wind-driven rain, evaluated by applying water spray at increasing pressure differentials. | High-low track differential with concealed external drainage; siliconized weatherstripping at overlaps; rubber strips or sealant at fixed glass areas. | AS2047 or EN 12208 water penetration test report for the configured sash and track assembly. |
Air Tightness | Resistance to air infiltration through joints and weatherstripping, measured as airflow rate per unit perimeter at a standard pressure differential. | Confirm the required air infiltration class for the target project. | EN 12207 or ASTM E283 air leakage test report for the specified configuration. |
Sound Insulation | Reduction of airborne sound transmission through the window assembly, expressed as a weighted sound reduction index. | Confirm the required acoustic rating for the target project's noise environment. | EN ISO 10140 or ASTM E90 laboratory acoustic test report for the specified glass and frame configuration. |
