Insulation to meet code

[Heather V.]

Hi all,

My husband and I are going to go the yurt route! We want to build a house eventually but plan on living in the yurt for a few years before and during the project. We spoke with the local building inspector and his biggest concern was the

insulation

. Code says the walls have to be R21 and the ceiling has to be R49 (!). We are trying to figure out a way to add the

insulation

without taking away from the structure. We would like to put as much of it between the cover and liner as we can so it doesn't make our space smaller or cover the lattice(although we are prepared to cover it). If we use fiberglass and put it between the rafters it will make the ceiling almost a foot shorter! The trick is we have to have a material that has a stated R value. I saw the post about ethafoam and it sounded great because it hold its shape well but I couldn't find its R value. Any suggestions are greatly appreciated!
