PVC Strip Door  Curtain, 41.3x86.6in Clear Plastic Vinyl Door Strips Windbreak Walk in Freezer Cooler Curtain Strips for Doorways of Supermarket, Garage, Warehouse, Pet Animal House

This product is an absolute waste of time and money if you are using them for a FREEZER. The entire kit is cumbersome to assemble. It comes with a strange sticky residue that’s difficult to wash off, and it’s already too late before you realize you need gloves to handle it because you’ve touched it. The hanging hardware is pretty flimsy and difficult to align. More importantly, it completely failed at its main job, which was insulating a sub-freezing environment. The vinyl strips became instantly rigid and hard in the cold. They lost all flexibility, turning the entire curtain into a brittle and hard curtain of panels. It was just totally useless for a freezer doorway. The product material is clearly not rated for sub freezing storage, despite the commercial label. It went straight into the trash. Had no other possible use for this. Very disappointed and dissatisfied.

These clear vinyl strip curtains are effective for regulating airflow between rooms, making them ideal for temperature control in spaces like stairwells or workshops. The material is thick and durable, offering solid insulation while still allowing visibility through. However, it’s worth noting that the strips come with a sticky or oily film from manufacturing - most likely so they won't stick together in transport, but it requires thorough cleaning before installation to achieve a crystal-clear finish. Once cleaned, they hang smoothly and work exactly as intended, creating a practical and affordable way to separate areas without blocking light or accessibility. I'll update once they're hung so you can see how they appear if used for stairwell openings.
