Insulation

[Corinarose]

I live in vermont and have a 30' yurt with the full

insulation

and snow load package.
I heat with wood and was able to be toasty warm when the wood was burning. What bothers me though is for a space that is just over 700sf I am burning more wood then friends in conventional homes with much more space.
I want to find a way to add

insulation

that helps to hold heat not just lose heat

I wanted to live in a yurt to simplify~maintaining a woodstove in a yurt is by no means simplifying~ it is a full time job. I have a great stove.

Have others used insulation beyond the reflectix insulation? Sources?

Thanks
