However U-value is the measurement of heat transmission through concrete slab from ground into the closed space or vice versa. The higher the number the more resistant the material is. Foam insulation is about 20 times more energy efficient. R-value is the measurement of concrete slab or other material capacity to resist heat flow ie. In general a solid concrete wall 12 inches thick only has an R-value of around 2. Compare that to rigid foam with has between a 3-4 R-value per inch.
Thermal conduction is not the only mode of energy loss in a building.
By doubling the thickness of the wall to 16 inches the R-value only increases by 050. A wall of greater thickness would be more optimal in terms of insulating value if it were of lightweight or low density. Backer – 182 Vinyl Siding –. Zones 3 and 4 include the Midwest and Northern regions requiring R-10 to R-19 values. Whole wall systems are generally the most reliable method for determining R values for insulation of walls.

What about your attics floors or crawlspaces where you might need higher R-values. ICF walls consist of a center cavity to contain concrete between two layers of EPS which provide two continuous layers of insulation rated at R-22 and higher. When heat or cold comes in contact with concrete it passes right through with almost no resistance. The higher the number the more resistant the material is. It takes into account additional materials such as windows door and exterior corners.
