[Cob] Insulative valuesDulane silkworm at spiderhollow.comTue Nov 22 22:54:57 CST 2011
Change may yet free us all. Maybe there is merit in this video. If the walls are thick enough, a little garbage can be a good thing. http://www.youtube.com/watch?v=EVWRHt7tYlI&feature=related -----Original Message----- From: coblist-bounces at deatech.com [mailto:coblist-bounces at deatech.com] On Behalf Of Damon Howell Sent: Tuesday, November 08, 2011 1:47 PM To: coblist at deatech.com Subject: Re: [Cob] Insulative values Christopher wrote: An inquisitive mind that challenges the status quo (even if it's the natural building status quo) is healthy for all of us. Blind faith is a poor mindset and is not empowering to the individual. Although blind faith is bad and challenging bad policy is good, changing for the sake of changing is naive. Building practices have been honed over generations, so we're not reinventing the wheel. Enough research has been done to show insulative values of cob are sadly low. I have read that the best approach to designing with insulation is thermal mass on the inside to act as a temperature regulator and insulation on the outside. BUT the problems with this approach is the cob can't breathe, so it can't dry out which will cause 1. the wall to eventually collapse, 2. mold, 3. a lot more woodwork for framing. You'd need to build an air gap in between the walls and that gets into a lot of extra work and know-how. One of the lures of cob construction is the do-it-yourself and affordability...
