After the published tables the silica aerogel is a very good thermal insulator.
Yes. Aerogel is less dense than radon. I think it's also less dense than xenon. For a while I wondered about it too, but yes, a solid can float on a gas.
Pentane is 0.626 g/cm^3 at 25 C and one atmosphere. Hydrogen is 0.070 g/cm^3 at -253 C and one atmosphere.Read more: What_is_the_lowest_density_liquid_commonly_availablei did not wright this!

regular (silica) aerogel is not lighter than air but SEAgel is a form of aerogel that is lighter than air
The most common use for Aerogel is for thermal insulation. Silica Aerogel has been used to help insulate the Mars Rover and protected all the wiring from the extreme temperatures it faces in outer space.

the aerogel
The proper spelling is aerogel. It is not specially capitalized at the beginning or in the middle, nor should it contain a hyphen or a space. The word has been in technical usage since 1931 and is not a tradename or proper noun. Common incorrect spellings include "Aerogel', "AeroGel", "aero-gel", "aero gel", and alternative phonetic spellings such as "airojell" and "aerojell".

Aerogel is 39 times more insulating than the best fiberglass ever made.
After the published tables the silica aerogel is a very good thermal insulator.
Silica aerogel of ·1 g/cm3 starts at $8/g or 80¢/cm3. If you'd like densities toward the record of 1 mg/cm3, multiply by--I don't know--500? Carbon aerogels are somewhat cheaper, resorcinol formaldehyde cheaper still. You could make your own and maybe do better. It seems a 3mg/cm3 aerogel costs $2100/g or $6·2/cm3.
