75 Series Aluminum BI-FOLDING GLASS DOOR

Benefits of 75 BI-FOLDING GLASS DOOR SERIES

Stable Structure & Strong Load-Bearing Capacity：Adopting 75mm thickened profiles and matched with heavy-duty hardware, it meets the needs of most large-opening scenarios and is applicable to various large-space settings.

Excellent Thermal Insulation & Soundproofing Performance：The profile has a built-in thermal insulation structure, and when combined with multiple sealing strips, it can effectively block temperature differences, reduce heat transfer, and isolate noise at the same time, creating a quiet and comfortable indoor environment. For example, when equipped with 5mm+12A+5mm insulated glass, it can reduce noise by more than 30dB.

Efficient Space Utilization：When folded, it can retract to both sides, enabling full ventilation and unobstructed views. Moreover, the door leaves are aligned on the same vertical plane when folded, presenting a concise and neat visual effect without occupying excessive space.

Superior Sealing & Waterproof Performance：The overlapping part of the frame and sash adopts a three-layer rubber strip sealing design, and the cavity uses EPDM (Ethylene Propylene Diene Monomer) sealing strips, which are resistant to aging and durable. The lower rail is designed with double waterproof rubber strips and a drainage system, completely solving the problems of rubber strip aging and water leakage that occurred in previous products.

Aesthetic Appearance & Versatile Style Compatibility：With a moderate overall size, it does not look bulky due to excessive thickness. The frame and sash are connected at a 45-degree angle, ensuring firmness, safety, and an elegant appearance. Meanwhile, a variety of colors and surface treatment processes are available, making it compatible with most space styles.

Safe & Convenient to Use：It is standardly equipped with high-end hardware hinges, which are firm and durable. The widened and thickened automotive-grade sealing strips have an anti-pinch function. The door opens and closes flexibly and smoothly, effectively protecting family safety. In addition, it has strong detachable performance, facilitating cleaning and maintenance with low maintenance costs.

Common FAQ

Q: What does “75” in the 75-Series specifically refer to? What are the differences between it and other series (such as the 80-Series and 65-Series)?

A: “75” refers to the main width of the profile being 75mm. Compared with the 65-Series, its profile is thicker and has stronger load-bearing capacity; compared with the 80-Series, it is thinner and lighter, and suitable for slightly smaller openings. It is a “golden size” that balances strength and space adaptability.

Q: During daily use, is the track prone to dust accumulation and jamming?

A: The track is designed with a slightly inclined water guide groove, which prevents dust accumulation and water retention.

Q: Can the glass be customized? For example, can double-layer insulated glass or Low-E glass be used?

A: Yes. The glass notch of the 75-Series profile is compatible with glass with a thickness of 5-20mm. Customization options include double-layer insulated glass and Low-E energy-saving glass, to meet the needs of thermal insulation, sound insulation or privacy protection.

Q: Can the aluminum alloy folding door be installed together with fixed doors or windows?

A: Yes. The aluminum alloy series folding glass doors are designed with certain flexibility and can be combined and installed with fixed doors or windows according to actual needs, so as to meet different spatial layouts and usage requirements.

Q: Will the glass fog up?

A: Generally not. If double-layer glass of specifications such as 5mm+6A+5mm is used and the glass is professionally manufactured, there will be no fogging between the double layers of glass.

Q: How does this door perform when used in cold climates?

A: The Aluminum Alloy 75-Series Folding Glass Door is designed to meet the usage requirements of different climatic conditions. Especially in cold climates, its built-in thermal insulation structure and multiple sealing strips can effectively block temperature differences and reduce heat loss. When matched with double-layer or multi-layer glass, it can provide excellent thermal insulation performance to resist cold weather.
