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.

A thermal protective structure applied over a substrate, the thermal protective structure comprising a mesh support structure having a plurality of spacers formed integrally therein and an active thermal protective material applied to the support structure, the active thermal protective material forming a continuous layer which is held, through the major part of its extent, spaced from the substrate by the spacers and responding to thermal extremes to protect the substrate. In combination, a metal cable tray containing a plurality of electrical cables extending in a first direction, and a thermal protective structure applied as an envelope around the cable tray, the thermal protective structure comprising a mesh support structure having a plurality of spacers formed integrally therein, said spacers comprising stiffening ridges, said integral spacers extending transverse to said first direction, and an active thermal protective material applied in a continuous layer to the support structure, the active thermal protective material being held, through the major part of its extent, spaced from the cable tray by the integral spacers and responding to thermal extremes to protect the cable tray.
