Doors higher than the frontage?

The advantage of a self-supporting frame combined with a wind-resistant folding curtain

This major distributor of bulk products for agriculture wanted high-speed flexible doors with maximum opening height which also needed to stand up to wind pressure.
The very high wind resistance of Nergeco Entrematic folding curtains results, when the door is open, in a greater height being taken up than with a simple roller curtain. This disadvantage is overcome by the self-supporting capabilities of the multi-folded steel frames for Nergeco high-speed flexible doors which allows them to protrude beyond the parapet of the frontage and which, incidentally, provides an interesting architectural rhythm to this frontage.
