Here is the SuperTherm ceramic insulation I was talking about. It is applied the same way as paint is applied to walls. It can be sprayed on or applied using a roller. It is approximately $100/gallon, and one gallon is typically applied to 100 sq. ft. (spicoatings.com)

BioBased Insulation makes a spray in insulation that is soy based. It is environmentally friendly, healthy, VOC free, pest resistant, water based and acts as a vapor retardant. I figured a house that was 20′ by 50′ with 2×6 framing and 2×12 roof joists and got an estimate of $7,800 which seems a bit steep. And with an R-value of 13 with standard 2×4 framing, it isn’t that impressive for the price either considering you can get an R15 out of your typical 3.5″ pink fiberglass insulation.
Winterpanel manufactures SIPs that can come prefaced in finished wood or wallboard. A 6.5″ panel can have an R-value of up to 38 and will cost $212.16 per panel.

This is one example of Straw Bale construction. Since energy efficiency is going to be a major goal in my project straw bale construction is extremely relevant. Straw Bales are essentially a waste product. The material is normally burned in the fields after harvest. Benefits include super insulation, which allows the unit to be cool in the summer and warm in the winter, and an overall inexpensive construction process.
