> As some of you know, at 3crow, I've been working with sawdust materials for

> the last three years. I've finally named the materials sawdobe and sawcrete

> depending on whether clay/lime or Portland cement is used in the mix but

> perhaps I should also add light sawcrete and light sawdobe to the

> nomenclature for my wall fill mixes as they are very light on the clay/lime

> or Portland cement, between 7 to 1 and  9 to 1.

> For my slabwall fill (which I'm in the process of finishing up) I'm using

> light sawcrete in potentially wet area applications and light sawdobe in the

> more protected high and dry areas. For the most part I'm using a wonderful

> shredded chip from a poll peeler that acts as good or perhaps better than

> straw as a binder. This summer my daughter used it in a mix over my bag wall

> and now it's dry and very hard and has quite the rough texture that will

> definitely give the next layer of natural plaster something to grab on to.

> In the cavity between the ceiling and roof I have a 2"- 4" layer of sawdobe

> and 12+" sawdust lime or between R 46 and R 54. next year I'll add the

> living roof part.

> So for Bradley Pride's question on o_a  I would highly recommend using

> sawdust or/and wood chips in your building.

> I think using stones from your land would be a superior idea in building

> your "kinda victorian" timber frame home. But you are right in thinking it

> will be a more expensive project than a simple passive solar earthshelter.

> As you design it remember contemporary thinking is backwards. The mass

> wall... brick, adobe, tile or stone should be to the inside, to soak up heat

> and slowly radiate it back into the room, and the insulating material should

> be to the outside with a protective skin over it. Now if you are working

> with stone you can have both. For the outside walls think of using a double

> stone wall with a 16" cavity filled with light sawcrete and/or sawdobe.

> Behind any surface where there will definitely be exposure to direct water

> use sawcrete* switching to light sawcrete as you get past that area and for

> any higher areas out of the range of direct water contact you may be able to

> use light sawdobe.

> Is there anyone else out there currently using sawdust and wood chips?
