FREQUENTLY ASKED QUESTIONS

Q1:How does this folding door contribute to "Energy Saving" in residential projects?

A: The DERCHI 80 Series is explicitly engineered for premium energy conservation. By combining a 6063-T5 thermal break profile with a 5mm + 20A + 5mm double-tempered glass system injected with Argon gas, the door creates a strong thermal barrier. This drastically minimizes thermal conductivity (lowers U-factor) and keeps indoor temperatures stable, reducing heating and cooling costs.
Q2:Is this folding door structurally safe for severe outdoor windproof applications?

Yes, absolutely. Built with an upgraded 2.0mm structural aluminum wall thickness, this door delivers high torsional rigidity and structural deflection resistance. It is fully certified under NFRC and AS2047, proving it can withstand heavy outdoor wind pressure and harsh weather when installed on exterior balconies, patios, or commercial entries.
Q3:What makes American CMECH hardware essential for this multi-panel accordion door?

A: Folding systems demand heavy-duty hardware because the entire weight of multiple panels rests on the tracks and hinges. American CMECH hardware provides industry-leading structural strength and precision engineering. It prevents the door panels from sagging over time, ensuring a smooth, frictionless push-and-pull motion for decades.
Q4:What custom sizing and color options do you offer for the 80 Series?

A: We offer complete architectural customization. Each single folding panel can be tailored within a width of 500mm to 850mm and a height of 1900mm to 3000mm, allowing you to combine as many panels as your layout requires. For aesthetics, we provide high-grade powder-coated surface finishes in any customized color to match your modern design style.
Q5: Can this system be used for both indoor and outdoor installations?

Yes, it is highly versatile. It features multi-layered weather stripping and superior water tightness for severe Outdoor/Exterior environments (like patios, courtyards, and parks). Meanwhile, its sleek, narrow-frame modern design makes it an elegant choice for Indoor room dividers, wine cellars, or commercial office partitions.
Q6: What kind of specialized project solutions and after-sales services does DERCHI provide?

We offer a comprehensive "Total Solution for Projects" which includes customized 3D model design, graphic design, and cross-categories consolidation during your planning phase. For international peace of mind, we provide a warranty of more than 5 years alongside comprehensive after-sales care: online technical support, free spare parts, return/replacement options, and onsite inspections or installation training.
