PSP/Cob building

Jan 11, 2009 16:03:45

Hello All. I've been reading about two building techniques that have gotten me really excited but I can't seem to choose which one to utilize when it comes time for me to build my own home. I like the cost effectiveness and ease of use of PSP, and the shelter qualities of earth but would also like the soft lines and heat retention of cob building. Is it possible to build a half cob half psp structure? Anyone have any thouhts?

Would you want to build a cob house that is sunk into the earth a few feet? I wonder what the effect of earth matted against your cob walls would be. It is a possibility though.

Howzabout a PSP structure with internal cob walls?

I think a cob rocket stove would go really well with a PSP structure.

That is doubly-eco! Mike, regarding the interior of PSP, have you seen any sort of clay or cob material used for the walls, or for anything?

How about chimneys in PSP, any experience?

Are there any sort of interior materials (other than toxic paint and all the other conventional stuff) to stay away from when building PSP?

I've kinda wondered about this on exposed surfaces myself. I'd also like to integrate a rocket stove if possible.

I would definately stay away from cob exterior walls. I suspect that Paul's idea of interior cob could be sound. Just make damn sure that you don't let them get damp such as with the contact with high humidity summer air condensing on the cool inner walls. Keep windows closed summer days and open them at night.

Would the poly not protect the cob enough?

Are you gonna wrap your inner cob wall with poly?

I think that would make your house look like .... some sort of freaky leather, chains and rubber sex pit.

Steve, you sure are into some weird stuff.

Would the heat from the rocket stove mess with the poly? I am concerned it would melt it or at minimum thin it so it could tear.

It's a tiny ad. At least, that's what she said.
