[Strawbale] Living Roof (on strawbale) - advice?

[Heidi Wordhouse-Dykema]

Thanks everyone for the links and heads up on methodologies!! 

Speaking of beefier roof systems, I'm planning 16" OC for my trusses.  Did people find that adequate, or should one move spacing closer together to help support the extra weight of a living/green roof?

Robtom, I'm not gonna build a strawbale roof, darlin'.  I'll be building a strawbale infill building, that happens to have a living roof.  The living roof will have some flakes of straw on top of it to mulch up the dirt and protect it from rain the first few seasons, but goodness, I'd never try to insulate a roof with strawbales!  
That's what sheepswool is for! (grins)
