earthbag home free insulation idea in alaska

ok so in alaska we have mossy sod that we use for roofs in log cabins. usually we fram a roof plastic over it and roll the mossy sod over that! i have done a 3 part sand one part lime with lots of straw exterior plaster to help reinforce my walls and keep them solid. plastic is cheap and i want to know if i should plastic over the plaster before i roll the mossy sod over it or if i should roll it over the plaster with no plastic at all. plastic is cheap and 20$ worth will cover the whole earthbag home! the moss will give it a nice hobbit home style look. ill upload pictures after

I would use the plastic. Do you expect a deep snow load? Snow can go a long way to insulating both roof and walls.

Are you using the thick mix of lichens and moss know as Caribou moss?

I assume that you are heating with wood.

yes i can pack snow on top of the moss! will work great and im using a rocket mass heater for heating the interior! ill go ahead and plastic over it then and cut moss today. its really thick moss the kind that you sink into when you step on it

ok so i plasterd and plastic the whole earthbag house here in north pole alaska but we got slammed with a snow storm! i did cut just enough moss for the roof but i guess my earthbag home wont be insulated! i might pile snow against the walls to act as a insulator but im going to focus on the interior for now! ill build a arctic entryway then ill build the rmh but for now im totally screwd! winter usually doesnt come till mid october but it came early this year putting a damper on my production
