Thermal conductivity is the quantity of heat transmitted through a unit thickness in a direction normal to a surface of unit area, due to a unit temperature gradient under steady state conditions.
Been there tried that. Save your money. Studies show no difference. Thermal insulation properties of argon - PubMed Mobile
Placebo effect maybe? There really isn't a difference. Denser gas, yes. Dense enough to actually feel a difference....no.
