Abstract

An insulating isolator for a heat shield has a unitary first land, a bead portion, a second land and a half bead. The first land defines a fastener aperture. In one case, a plurality of circumferentially spaced apart petals is formed in the isolator. The petals may be separated by gaps. In another case, a set of circumferentially spaced apart apertures are formed in the isolator.The heat shield may have at least two disk apertures. Two metallic disks are located in the area of at least one of the two disk apertures. The metallic disks are connected to each other, have aligned fastener openings that are smaller than the disk apertures and they are smaller than the metallic sheet. One of the metallic disks may have a bead.
