VERILON® Strip Doors are used throughout industrial, commercial and institutional structures, both indoors and outdoors. You can see through it, walk through it and drive through it. Made up of a series of overlapping flexible VERILON® vinyl strips that are transparent, odorless and non-toxic. The strips part only enough to let a person or truck pass through. The balance of the strips remain closed with the parted strips falling right back into place automatically after passage, ensuring minimum loss of expensive heated or cooled air. VERILON® Vinyl Strips are tough, sturdy - able to withstand the impact of heavy equipment and constant use.
