DEI Exhaust Heat Wrap. Constructed from pulverised lava rock, extruded into fibres and then woven into a tight weave gives this material titanium-like strength and toughness. Typical glass fibre wrap will handle 1200°F of maximum direct heat, while Design Engineering’s new Titanium Wrap, using LR Technology, is capable of handling direct continuous heat up to 1800°F and radiant heat up to 2800°F.
