The thickness refers to how dense the vinyl strip curtain material is.

.060is the thinnest available material and is an excellent alternative for walk-in coolers.

.080can be used with carts, pallet jacks and light forklift traffic. Okay in small exterior doorways with some air movement and cold storage coolers or freezers.

.120can be used with heavy lift-truck traffic in docks, doorways and cold storage coolers or freezers. Okay for use in exterior doorways and dock enclosures. Provides good sound attenuation.

.160can be used with heavy duty lift-truck or vehicle traffic in large dock, door or craneway openings. Reduce sand, dust, chip and wind penetration. Not designed for walk-through.

When selecting material thickness, your choices will be limited according to the type of material and strip width that you choose.
