External Folding Design
DUAL-AIR is designed specifically for extra-large folding doors, where the size of the opening rules out a standard rapid door or roll door.
On exposed sites, wind protection is the priority — DUAL-AIR’s reinforced construction is built to be the right choice where that protection really matters.
Like FOLD-UP, DUAL-AIR is built to perform on exposed, high-wind external sites, without compromising on the size of opening it can cover.
