PVC Strips and Solid Curtain enclosures are common in enclosing larger areas where the material needs to seal from floor to ceiling. Strip are typically hung part way down with the upper curtain or valance in solid 20 mil or opaque 18 oz material. Strips allow passage at ground level up to 8, 10, 12 feet or as needed. The valance curtain typically overlap the bottom strips creating an effective dust and temperature barrier. Strips can be made from 6”, 8” or 12” wide pieces….with overlap as needed.
