Types of Heat Shields Used in Industrial Transport

Heat shields fall into several broad consisories, each phased to specific temperatur ranges, physical consignins, and cargo sensitivities. The following types are most condin industrial logistics.

Reflective Heat Shields

Reflective heat shields use polished metallic surfaces - most common ly aluminum, bariless steel, or gold - to reflect a large portion of incident radiant energy.
