<p>A heat shield (10) disclosed having a flexible substrate (12) attached to a corrugated insulating layer (16). An outwardly facing metalized or metal foil reflecting layer (14) is positioned on the flexible substrate (12), and air pockets (26) are formed between the corrugation of the insulating layer (16) and the substrate (12). Resilient elongated filamentary members (28) are distributed throughout the insulating layer (16) and are biaised into a waveform shape matched to the corrugations to support the insulating layer (16) and prevent collapse of the air pockets (26). A reinforcing layer (30) is positioned on the corrugated insulating layer (16) opposite the flexible substrate (12) forming a second layer of air pockets (32). The reinforcing layer (30) is formed of a scrim of woven or non-woven insulating material.</p> |
