Isn’t aeorogel really expensive to begin with? I mean we have tech like Ytong and they are still using bricks in buildings. Why? Ytong seems expensive to uneducated who have no clue about TCO and engineering.
Aerogel is insanely expensive. It has an R-value of 10 per inch and the handy property of costing about $1 per R-value per square foot. So a piece of aerogel 1" thick by 4’ x 8’ would cost $320; the equivalent piece of 2" thick XPS foam board (also R-10) costs about $50 these days. So with aerogel you’re paying a 500% to 600% premium to have your insulation be half as thick as XPS would be - and to essentially have no compression resistance at all (vs. the 20+ PSI of foam board).
