Dual International Certification (NFRC & AS2047) Fully tested and certified under the USA NFRC and Australia AS2047 frameworks. This guarantees structural deflection compliance, legal building permit approvals, and high performance in energy efficiency audits across North American and Oceanian markets.
02

Premium American CMECH Hardware Integration

Premium American CMECH Hardware Integration Utilizing elite American CMECH hardware, the heavy-duty bottom-rolling and top-guided mechanisms ensure frictionless, fluid folding motion. The architectural hardware provides maximum multi-point security locking and resists heavy cycle wear across decades of operation.
03

Superior Thermal & Acoustic Insulation (Argon-Filled Cavity)

Superior Thermal & Acoustic Insulation (Argon-Filled Cavity) Featuring a massive 20A (20mm) spacer injected with premium Argon gas paired with thermal break profiles, the 80 Series dramatically dampens external noise and blocks convective heat transfer, optimizing indoor HVAC performance.
04

Hurricane Impact & Severe Weatherproof Engineering

Hurricane Impact & Severe Weatherproof Engineering Fabricated with a rigid 2.0mm thickness structural profile and heavy automotive-grade double tempered glass, this folding door handles intense outdoor wind loads, tropical storms, and structural stress without compromising water tightness.
05

Flexible Open-Space Maximization

Flexible Open-Space Maximization Designed with narrow-profile single panels (500mm–850mm wide and up to 3000mm high), it effortlessly stacks away to open up 95% of the wall aperture—making it ideal for converting structural walls into panoramic view lifelines.
06

Ultra Durable Anti-Corrosion Aluminum Frame

Adopting aerospace-grade aluminum alloy with complete powder coating surface treatment, the frame effectively resists salt spray, rain corrosion and UV fading. It maintains stable appearance and structural performance for over 30 years in coastal, high-temperature and humid regions without rust or discoloration.

FREQUENTLY ASKED QUESTIONS

Q1: Is this folding door structurally certified for severe weather and hurricane regions in the US?

A：Yes, absolutely. The DERCHI 80 Series is fully NFRC certified for thermal and air-infiltration criteria. With its heavy-duty 2.0mm profile wall thickness and optimized double tempered glass layers, it is engineered to withstand extreme positive and negative wind pressures, making it excellent for outdoor exterior patio and coastal applications.
Q2: What are the insulation benefits of the "5mm + 20A + 5mm with Argon Gas" glass setup?

The 20A (20mm) space acts as a heavy acoustic and thermal buffer. By injecting Argon gas into this hollow space, we reduce internal moisture/condensation and lower the door's overall U-factor. It delivers elite heat insulation and soundproofing, blocking street and outdoor noises efficiently.
Q3: Why does DERCHI specify American CMECH hardware for the 80 Series Folding Door?

Folding doors carry tremendous structural load on their tracking systems. American CMECH is a world leader in architectural hardware. Its heavy-duty rollers and hinges ensure the panels slide and fold smoothly without sagging over time, providing highly reliable security and air-tight locking performance.
Q4: What custom sizes can be accommodated for large structural patio openings?

While we offer full-scale custom sizing tailored to your blueprints, our single panel configuration ranges from 500mm to 850mm in width and 1900mm to 3000mm in height. This allows us to link multiple panels together to span massive architectural openings while keeping operations lightweight.
Two primary surface treatment options are available:
•Powder Coated (standard) — durable, cost-effective, available in a wide range of colors
•PVDF Coating — premium option with superior UV resistance and color retention for 15+ years
Both treatments provide excellent anti-corrosion protection suitable for coastal and high-humidity environments. Available colors include White, Black, Grey, Bronze, Champagne, Dark Brown, and fully customizable RAL or Pantone specifications.Our standard build uses 5 mm + 20A + 5 mm double-tempered insulated glass with argon gas. The following options are also available:
•6 mm + 18A + 6 mm double-tempered glass with argon gas — for enhanced impact resistance
•8 mm + 14A + 8 mm double-tempered glass with argon gas — for maximum strength applications
•Triple tempered glass with argon gas — for superior thermal and acoustic insulation
•Low-E coated glass — for improved solar heat rejection and energy efficiency
•Acoustic laminated glass — for sound attenuation in urban and high-traffic environments
•Reflective and tinted glass — for solar heat gain control in hot climate regions
Q5:Can this folding door be installed as an exterior entry door? Are colors customizable?

A: Yes, it is explicitly built for Exterior/Outdoor use with multi-layered weather stripping, though it is versatile enough for commercial interior partitions as well. For aesthetics, we offer fully customized powder-coated colors to seamlessly blend with your modern architectural themes.
Q6: What specific project solutions and after-sales support do you extend to developers?

A: We offer robust graphic design and structural engineering alignment during the design phase. For international orders, our service includes a warranty of more than 5 years, comprehensive online technical support, free spare parts, return/replacement policies, and even onsite training or installation coordination when requested.
Q7: How are products packaged and shipped internationally?
Our export packaging is engineered to guarantee damage-free arrival at any global port:
- Full-surface protective film applied to all aluminum profiles before packaging
- High-density foam corner protectors cushion all frame edges against transit impact
- ISPM-15 certified fumigation-free wooden or steel pallets meet international customs requirements
- Air-bag container securing system prevents load shifting during ocean transit
- Each shipment includes packing list, commercial invoice, and Certificate of Origin
We support FOB, CIF, CFR, and EXW trade terms with extensive experience in ocean freight to ports worldwide.
