Most common materials are PVC vertical blinds
First lets look at materials and styles. Most common materials are PVC vertical blinds (vinyl), fabric, and fabric insert. PVC vinyl technology has improved dramatically. You can get a rich textured look or smooth soft look. Both are available in many colors. The back side on all is usually a shade of white. Vinyl vanes are mostly curved so when rotated to a closed position, they close tightly. Vinyl’s are easy to clean and hold up well in high traffic areas.
Fabric or fabric free hang are an excellent choice if you want light filtering. They don’t close as tightly as vinyl when rotated shut. They also come with weights at the bottom of each vane.
