Product Details
The 120 x 80 patio door is an ultra-narrow hanging sliding door built for projects requiring both visual elegance and structural resilience. Its hidden nine-tier structure incorporates multiple barriers that progressively weaken outdoor wind pressure, making it suitable for severe weather regions. The track-mounted anti-balance wheel delivers anti-typhoon and anti-fall protection, keeping panels secure under extreme conditions. With a 2.5mm frame and 2.0mm door leaf, the door balances slim lines with rigidity. Double tempered glass (5mm+12A+5mm) with argon fill and PVDF aluminum spacers delivers measurable thermal and acoustic performance. Buyers considering this as a 48 x 80 sliding glass door option must confirm the measurement units for the 120 x 80 dimensions with the supplier before ordering.
Product Features
Hidden Nine-Tier Structure: This 120 x 80 patio door uses a concealed nine-tier design with multiple barriers that progressively reduce strong wind pressure. Unlike single-barrier doors, the layered approach distributes wind loads across several points, improving stability. Buyers in high-wind regions should verify this configuration meets local building codes for their project location.
Anti-Typhoon & Anti-Fall Protection: A track-mounted anti-balance wheel secures panels against uplift and derailment during typhoon-force winds. This prevents the door leaf from blowing off track or falling inward, addressing a critical safety concern for coastal installations. Buyers should confirm rated wind speed capacity for their conditions.
Ultra-Narrow Hanging Design: The minimal frame maximizes glass area while maintaining structural integrity through 2.5mm frame and 2.0mm door leaf thickness. The hanging sliding mechanism eliminates floor tracks, creating cleaner threshold transitions. Projects requiring accessibility compliance should confirm threshold details with the supplier.
Advanced Sealing System: EPDM rubber strips combined with siliconized wool strips create comprehensive weather sealing. EPDM resists UV degradation and temperature extremes, while siliconized wool provides secondary draft protection. Buyers targeting extreme climates should request specific sealing test data.
Thermal & Acoustic Performance: The 5mm+12A+5mm double tempered glass with argon achieves a U-Factor of 0.28 and SHGC of 0.22. Sound insulation reaches 30 dB, reducing external noise. Buyers should request certified test reports to confirm these values meet their 48 x 80 sliding glass door project specifications.
Customizable Styles
Glass Options: The standard configuration uses 5mm+12A+5mm double tempered glass with argon and a PVDF aluminum spacer. Buyers needing enhanced acoustic or thermal performance may discuss alternative glass thicknesses or triple-glazed options. Glass selection directly impacts energy ratings, so confirming configuration against project requirements is essential for this 120 x 80 patio door.
Frame Options: The aluminum frame features 2.5mm profile thickness and 2.0mm door leaf thickness. The exact alloy grade should be confirmed, as material composition affects structural performance and corrosion resistance. Coastal or industrial environment buyers should verify frame material meets durability requirements.
Size Options: The product references 120 x 80 dimensions; however, measurement units are unspecified and must be confirmed. Accurate opening dimensions are critical for proper installation. Buyers should provide exact rough opening sizes and request confirmation the door fits their project.
Color/Finish Options: Surface treatment and color options are not specified. Buyers should inquire about available finishes such as powder coating or anodizing, and request samples for visual matching. Confirming finish durability and UV resistance for the intended environment is recommended.
Track Configuration: Available in two-track (103mm frame) or three-track (149mm frame) configurations. Two-track suits standard openings with a slimmer profile, while three-track accommodates wider openings. Buyers evaluating a 68 x 80 sliding patio door layout should select the track configuration based on opening width and panel arrangement needs.
Project Customization: Optional hardware packages (New 47 Pack, 70 Pack, 75 Pack, 100 Pack) may accommodate different project scales. Package contents are not detailed and should be confirmed. Large-scale installation buyers should discuss custom packaging and bulk configuration options with the manufacturer.
Hardware Accessories
Handle: Handle specifications are not detailed in current data. Handle choice impacts daily operation comfort and the aesthetic of the 120 x 80 patio door. Buyers should confirm handle style, material, and finish options, ensuring the selection complements the door design and meets accessibility requirements.
Rollers: The track-mounted anti-balance wheel system provides both smooth operation and anti-typhoon, anti-fall safety. This dual-function roller keeps the panel on track during extreme wind while maintaining easy sliding under normal conditions. Buyers should confirm expected operational lifespan and maintenance requirements.
Buffer/Soft-Close System: Buffer or soft-close specifications are not provided. A soft-close mechanism prevents panel slamming, reducing hardware wear and improving safety. Buyers requiring soft-close functionality should confirm its availability and compatibility with their selected track configuration.
Lock: The flush lock is a PAG Aluminum Hook Lock, providing secure engagement when closed. The hook-style mechanism offers enhanced forced-entry resistance compared to standard latches. Buyers should verify this lock meets security requirements and confirm additional locking point options.
Track System: The track accommodates two-track or three-track configurations with frame widths of 103mm and 149mm respectively. It supports the hanging sliding mechanism and integrates the anti-balance wheel. Buyers considering patio doors 8 feet wide should confirm track material and installation requirements for their conditions.
Sealing/Connection Hardware: EPDM rubber strips from JIANGYINHAIDA and siliconized wool strips provide primary weather sealing. These components are critical for maintaining 300pa water tightness and air tightness. Buyers should confirm expected service life and replacement seal availability for long-term commercial projects.
