VERTICAL BI-FOLD DOORS

FourSeasonDoors is the exclusive manufacturer of the Hydraulic Bi-Folding Door and Window System, as well as the Hydraulic and Single-Swing door/window systems. Through creative design and engineering excellence, we produce innovative architectural hydraulic doors and windows. With an emphasis on ease of installation and simplicity of use, our products redefine the way in which you interact with the spaces around you.

The hydraulic bi-folding system opens vertically, allowing smooth and quiet access between environments with just the press of a button. By incorporating the bi-folding door or window system, the barrier between the interior and exterior vanishes, and the ambiance of the outdoors is allowed to flow in. Designing allows light and motion to easily move through your interior space.

Key Benefits:

Shipped with rust-resistant, red-oxide primer, ready for field finishing
Manual lowering system in case of power failure
Total security without the use of locking mechanisms – The hydraulic cylinders draw the system panels closed with 1,000+ lbs. of force, creating a tight seal around the perimeter
Full perimeter weather seals
Integral mounting frame to limit loads on the structure
Precision welds at all frame joints
Heavy-duty bottom rollers are entirely captured by the SST-II frame, keeping the system secure at all times
No floor track is required – Nothing to impair movement through the opening
When open the system forms an awning providing protection from the weather and sun
The use of hydraulics eliminates the need for limit switches
