The most important part is insulation. With sealed, thin sheet aerogel insulation just a few millimeters thick, with minimal energy use, buildings could be cold in the heat of summer and hot at the coldest time of winter.
And this also applies to appliances like ovens and refrigerator/freezers. Line them with sealed aerogel panels and once at temperature, with minimal extra energy they stay there.
Aerogel is so efficient that it cannot be used in clothing, even in Arctic conditions.
You got may interest so I priced out Aerogel at one internet site and for a mere $250 I can buy a single sheet 4 feet x 30 inches that’s a whopping 6mm thick.
An online search of our local building supply stores do not offer this as a whole house wrap, or in any other manner for a home insulation.
It is not cost effective.
I’ve wondered for some time when high-end coolers will be made with aerogel. Seems obvious, so someone has undoubtedly considered it.
Yea, and all that aerogel will cost you a fortune.
