I've been trying to figure out what are the best ways of insulating a small woods house/cabin. My preference would be a brick house, rammed earth bale house, or some kind of greener structure that I can take advantage of the clay that available. I have ceramics experience and I've built brick kilns a couple times, so it would play to my strengths. Only problem is i dont know Jack about insulation. I know reflective materials help with thermoregulation, and I know what R values are suggested for the Rockies, but after that I'm afloat with no paddle. I know a dead air space between the inside and outside with a reflective surface on one side is good. I know that using rock wool or perlite fill or a perlite concrete wall sealed by sodium silicate can add insulation, and that one of the best means of limiting the difficulty of heating or cooling a structure is to simply keep it small. Ideally my homestead could be heated by one rocket stove, and I'd love to bury it slightly or have a decent portion if the space be under ground/basement to make use the root cellar effect to kind of keep it comfortable, and as the land I'm looking at is mountainous high desert that should be fine as far as drainage and moisture goes. I dont have a hookup for rockwool but I do have a connection that can get me perlite for about $150-180 a ton so that could be very nice for building up those r values. I made something in the past as an experiment that was perlite and slightly thinned glue (I want to say elmer's but it might have been something waterpoof) that was remarkably sturdy and had a decent insulation value (close to loose perlite, but safer when it comes to dust and could be kind of applied directly to a surface or formed into brick/panels with the aid of chalk dust. Downside is the glue looses perlite's benefit of being fireproof, but that's about it. Let's call it DRCT (The devil's rice crispies treat). Anyway, so, outside-in, brick wall, then DCRT at 3-4 inches thick, reflective material, 2-3 inch dead airspace, reflective material, inch of the DCRT and then interior walls, be they paneling or drywall or whatever. By my calculation I lose a fair amount of living space, but that averages out at around R-32 in a room with no windows and one average quality door. Assuming I understand how that works ( I probably dont). So, what do you think? Am I nuts and this wont work, or is this an ok idea?
