Tempro® Back-Stop™ curtains from Seymour Manufacturing are the first insulated flexible barrier to be designed to reduce energy loss from the back of a chilled or frozen vehicle. Made possible by the acclaimed unique thermal properties of Tempro®, the lightest, thinnest and most effective thermal insulator.

Substantial energy and fuel savings can be achieved when using Back-Stop™ and the flexibility and simple functionality of the system provides easy access during loading and unloading whilst still retaining the required temperature with the vehicle rear doors open.

SMI’s Tempro® Back-Stop™ is an insulated door curtain system based on SMI’s original development for supermarket cold rooms and freezer. Which save 25% in chillers and an amazing 33.3% in freezers.
