Wool prices grew 25 percent in 2003 to an average of $0.72 per pound, or a total value of $27.4 million, from $21.9 million in 2002.
Among the following materials, the one with the highest R-value per inch of thickness is typically closed-cell spray foam insulation.
As strange as it may sound dead or still air is one of the best insulators. Insulation such as fiberglass or rock wool and styrofoam work because they are fluffy with trapped air. If you have a sheet of four inch thick R40 fiberglass and squeeze it into a wall made of 2X3 studs you will have less R value than than a 3 inch piece of fiberglass insulation. So the highest R value goes to the insulation that traps the most dead air per inch of thickness and is installed propperly.
