Are there any problems with electric wiring overheating with airKrete insulation?
No. airKrete is 100% fireproof. Because airKrete’s main compound is a mineral-magnesium oxide- it is a poor conductor of electricity. If a short circuit develops in wiring within a cavity filled with airKrete, the short circuit will self-extinguish. airKrete is also non-exothermic, therefore it does not give off heat during curing.
