The Challenge
Why This Product Exists
Sliding doors provide wide openings but always leave at least one fixed panel blocking the view. When architects and homeowners want a truly open connection between indoor and outdoor spaces — where the entire wall disappears — sliding systems fall short. The challenge is creating a system that opens completely while remaining easy to operate and weather-tight when closed.

Common Questions
Frequently Asked Questions
A traffic door is one panel in the folding system that can be opened independently as a single swing door for everyday access, without needing to fold the entire system. This is essential for daily use.
Modern folding door systems with compression seals and proper drainage achieve excellent weather performance. However, due to the number of panel joints, they are slightly less air-tight than equivalent sliding systems. We recommend folding doors for sheltered locations or climates without extreme wind-driven rain.
