PVC Strip Door Kits do a great job of separating areas for temperature control and energy savings, but eventually, PVC strips will need to be replaced, due to natural wear and tear that happens over time. Some of the common reasons for replacing PVC strips are scratches on the surface that limit visibility or cracked or broken strips that allow air through the doorway. Strips that have lost there transparency can lead to an unsafe situation where you have traffic coming in from both directions, unaware of what is happening on the other side of the strip door.
