Abstract
According to some aspects, provided are curtain assemblies configured to operate in high wind environments. The curtain assembly can include first and second track guide including internal security rails. The internal securing rails moveably engage end portions of fabric stiffeners to provide stability in the curtain. In some embodiments, the securing rails include ramp portions to accommodate drift in the curtain and/or fabric stiffeners without compromising operation of the curtain.

A curtain assembly comprising:
- a curtain selectably moveable between an open position and a closed position, the curtain having a first vertical edge and a second vertical edge opposite the first vertical edge;
- a track guide having a first side constructed to guide the first vertical edge of the curtain and second side that is opposite the first side and constructed to guide the second vertical edge of the curtain, wherein the first and second sides define a plane of operation for the curtain as the curtain moves between the open position and the closed position;
- a plurality of stiffeners disposed within the curtain, each of the plurality of stiffeners comprising a cylindrical member having a first end constructed to engage a first channel in the first side of the track guide and a second end that is opposite the first end and constructed to engage a second channel in the second side of the track guide;
- a roll tube configured to wind the curtain and the plurality of stiffeners around the roll tube and unwind the plurality of stiffeners into the track guide;
- a first entry guide comprising a ramp region constructed to guide the first end of each of the plurality of stiffeners into the first channel;
- and
- a second entry guide comprising a ramp region constructed to guide the second end of each of the plurality of stiffeners into the second channel.
