Abstract

An envelope system for protecting a substrate from fire or other thermal extreme. The system includes a screen, which surrounds the entire substrate and which is set off from the substrate by ridges folded into the screen, and a thermal protective coating applied to the screen and spaced from the substrate by the screen to form an air gap between the substrate and the coating.
