Handing off aerogel blankets from Hebei to furnace overhauls in Saudi door plants and Australian solar setups, a common call comes in: "We wrapped thin, but surfaces stay hot—why?" One farm operator puzzled after blanketing a 300°C exhaust—the outside barely cooled. The culprit? Unchecked radiation from porous walls, not the aerogel.
Radiation's the silent thief in hot zones: Over 400°C, it outpaces conduction and convection, emitting waves that penetrate porous surfaces. Insulate without prep, and walls heat to extremes, "cooking" the blanket from inside. We've countered this by sealing walls first with reflective coatings or foils to bounce 70-80% radiation inward.
In a Saudi test, this dropped wall temps 25%, letting 10mm aerogel (0.02 W/m·K) slash losses 40% versus untreated. Easier wraps on bends, no compression issues in vibes. An Australian rig saved 20% material, payback in months via lower fuel.
We've mixed in powder fills for gaps too, boosting hybrids. If your furnaces face this radiation trap, what's your prep routine? Happy to compare notes on seals.
