Benefits of 80-SERIES THERMAL BREAK HEAVY DUTY BI-FOLDING DOOR

1.Equipped with heavy-duty hardware, each door leaf can bear a load of 150-200kg. It can be manufactured into large-size doors with a width of 3-8 meters, meeting the needs of large openings.

2.The thermal break structure blocks heat conduction of the profile. When matched with insulated glass, it provides thermal insulation in winter and heat resistance in summer, and also isolates external noise.

3.After folding, it can be fully retracted to both sides. There is no obstruction when opened, realizing seamless connection between indoor and outdoor spaces, with excellent viewing and ventilation effects.

Common FAQ

Q: What is the difference between “heavy-duty” folding doors and ordinary folding doors? Will they be bulkier?

A: The difference lies in hardware and profiles. Heavy-duty doors adopt thickened profiles (wall thickness ≥ 1.4mm) and dedicated heavy-duty hardware. Their load-bearing capacity is 2-3 times that of ordinary doors. However, they are equipped with precision bearings, enabling smooth and effortless pushing and pulling, and even better stability.

Q: Is the thermal insulation effect of the thermal break structure obvious? Will it leak air in northern winters?

A: The effect is obvious. The thermal break structure uses nylon thermal insulation strips to block heat conduction, and is matched with multiple sealing strips, which can reduce heat loss. It can help reduce heating costs in northern winters, and there will be no air leakage with proper installation.

Q: Will large-size doors be prone to deformation? What is their service life?

A: They will not deform easily. High-strength aluminum alloy profiles have strong anti-deformation ability. When matched with high-quality heavy-duty hardware, their service life can reach 15-20 years under normal use. Daily maintenance only requires regular cleaning of the tracks.
